Welcome to django-classy-tags’s documentation!¶

django-classy-tags is an approach at making writing template tags in Django easier, shorter and more fun by providing an extensible argument parser which reduces most of the boiler plate code you usually have to write when coding custom template tags.

django-classy-tags does no magic by design. Thus you will not get automatic registering/loading of your tags like other solutions provide. You will not get automatic argument guessing from function signatures but rather you have to declare what arguments your tag accepts. There is also no magic in your template tag class either, it’s just a subclass of django.template.Node which invokes a parser class to parse the arguments when it’s initialized and resolves those arguments into keyword arguments in it’s render method and calls it’s render_tag method with those keyword arguments.

Contents:

Installation¶

To install django-classy-tags, please use sudo pip install django-classy-tags.

If you don’t want to use pip, download the latest version from pypi, unpack the tarball and run sudo python setup.py install.

django-classy-tags has no dependencies other than Django. Django 1.11 and later are supported.

Usage¶

A simple example¶

A very basic tag which takes no arguments and always returns 'hello world' would be:

from classytags.core import Tag
from django import template

register = template.Library()

class HelloWorld(Tag):
    name = 'hello_world'

    def render_tag(self, context):
        return 'hello world'

register.tag(HelloWorld)

Now let’s explain this. To create a tag, you subclass classytags.core.Tag and define a classytags.core.Tag.render_tag() method which takes the context and any template tag options you define as arguments to the method. Since we did not define any options for this tag, it only takes context. The classytags.core.Tag.render_tag() method should always return a string.

classytags.core.Tag.render_tag on a tag class is what is used when registering the tag with a Django template tag library and also what will be used in the template.

Defining options¶

Defining options is done by setting the classytags.core.Tag.options attribute on your tag class to an instance of classytags.core.Options. The Options class takes any amount of argument objects or strings (called breakpoints) as initialization arguments.

Let’s build a tag which takes a single argument and an optional ‘as varname’ argument:

from classytags.core import Tag, Options
from classytags.arguments import Argument
from django import template

register = template.Library()

class Hello(Tag):
    name = 'hello'
    options = Options(
        Argument('name'),
        'as',
        Argument('varname', required=False, resolve=False)
    )

    def render_tag(self, context, name, varname):
        output = 'hello %s' % name
        if varname:
            context[varname] = output
            return ''
        else:
            return output

register.tag(Hello)

In a template we could now do either {% hello "world" %} which would output 'hello world' or {% hello "world" as "varname" %} which would output nothing but set the {{ varname }} template variable to 'hello world'. You may also use {% hello "world" as varname %} to achieve the same result like the last example.

Writing a block tag¶

You can write tags which wrap a block (nodelist) in the template. An example for this kind of tag is Django’s built-in {% with %} tag.

To write the {% with %} tag from Django using django-classy-tags you would do:

from classytags.core import Tag, Options
from classytags.arguments import Argument
from django import template

register = template.Library()

class With(Tag):
    name = 'with'
    options = Options(
        Argument('variable'),
        'as',
        Argument('varname', resolve=False),
        blocks=[('endwith', 'nodelist')],
    )

    def render_tag(self, context, variable, varname, nodelist):
        context.push()
        context[varname] = variable
        output = nodelist.render(context)
        context.pop()
        return output

register.tag(With)

Working with multiple blocks¶

If you’re working with multiple, optional blocks, the nodelist is always credited to the leftmost block name.

For example the Django for tag accepts an optional empty block. Let’s take following classytag options:

options = Options(
    CommaSeperatableMultiValueArgument('loopvars'),
    'in',
    arguments.Argument('values'),
    blocks=[('empty', 'pre_empty'), ('endfor', 'post_empty')],
)

If you use it with {% for x in y %}hello{% empty %}world{% enfor %} the pre_empty argument to your classytags.arguments.Argument.render_tag`() would hold a nodelist containing hello, post_empty would contain world. Now if you have {% for x in y%}{{ hello }}{% endfor %}, pre_empty remains the same, but post_empty is an empty nodelist.

Easy ‘as’ Tags¶

There is a helper class for tags which store their output (optionally) in the context. This class is in classytags.helpers.AsTag and instead of defining a render_tag method, you define a classytags.helpers.AsTag.get_value() method which returns the value you want to either display or be put into the context.

Here is a small example:

from classytags.core import Options
from classytags.arguments import Argument
from classytags.helpers import AsTag
from django import template

register = template.Library()

class Dummy(AsTag):
    options = Options(
        'as',
        Argument('varname', resolve=False, required=False),
    )

    def get_value(self, context):
        return 'dummy'

register.tag(Dummy)

Now if you do {% dummy %} in your templates, it will output ‘dummy’ there. If you use {% dummy as myvar %} ‘dummy’ will be stored into the myvar context variable.

Inclusion Tags¶

A helper class for inclusion tags (template tags which render a template) is provided at classytags.helpers.InclusionTag. Instead of the usual render_tag method it provides two methods classytags.helpers.InclusionTag.get_template() which by default returns the attribute classytags.helpers.InclusionTag.template and defines the template to use for rendering. The method classytags.helpers.InclusionTag.get_context() should return a dictionary holding the content to use for rendering the template. Both those methods get the context and the arguments of the tag passed as arguments.

A very simple example would be:

from classytags.core import Options
from classytags.arguments import Argument
from classytags.helpers import InclusionTag
from django import template

register = template.Library()

class Dummy(InclusionTag):
    template = 'dummy.html'

    def get_context(self, context):
        return {'varname': 'dummy'}

register.tag(Dummy)

With the following template for dummy.html:

varname: {{ varname }}

This would always render as varname: dummy.

Advanced Block Definition¶

Sometimes you might want to allow your blocktag to be terminated by a variable end tag to make templates more readable. This is for example done in the block tag in Django, where you can do {% block myblock %}...{% endblock %} as well as {% block myblock %}...{% endblock myblock %}. To do so in classytags, you have to use advanced block definitions using the classytags.blocks.BlockDefinition class together with the classytags.blocks.VariableBlockName class.

An example for a tag with the same signature as Django’s block tag:

class Block(Tag):
    options = Options(
        Argument('name', resolve=False),
        blocks=[
            BlockDefinition('nodelist', VariableBlockName('endblock %(value)s', 'name'), 'endblock')
        ]
    )

Arguments in depth¶

Examples given here are in tabular form. The non-standard options are a list of options to the argument class which are not the default value. The input is the single token in your template tag that gets consumed by this argument class. The output is the value you get in your render_tag method for the keyword of this argument.

Context for all examples: {'name': 'classytags'}

Reference¶

`classytags.arguments`¶

This module contains standard argument types.

class classytags.arguments.Argument(name[, default=None][, required=True], [resolve=True])¶

A basic single value argument with name as it’s name.

default is used if required is False and this argument is not given.

If resolve is False, the argument will not try to resolve it’s contents against the context. This is especially useful for ‘as varname’ arguments. Note that quotation marks around the argument will be removed if there are any.

value_class¶: The class to be used to wrap the value in. Defaults to classytags.values.StringValue.

get_default()¶: Returns the default value for this argument

parse(parser, token, tagname, kwargs)¶: Parses a single token into kwargs. Should return True if it consumed this token or False if it didn’t.

parse_token(parser, token)¶: Parses a single token using parser into an object which is can be resolved against a context. Usually this is a template variable, a filter expression or a classytags.utils.TemplateConstant.

class classytags.arguments.Argument(name[, default=None][, required=True], [resolve=True])¶: Same as classytags.arguments.Argument but with classytags.values.StrictStringValue as value_class.

class classytags.arguments.KeywordArgument(name[, default=None][, required=True] [, resolve=True][, defaultkey=None][, splitter='='])¶

An argument that allows key=value notation.

defaultkey is used as key if no key is given or the default value should be used.

splitter is used to split the key value pair.

wrapper_class¶: Class to use to wrap the key value pair in. Defaults to classytags.values.DictValue.

class classytags.arguments.IntegerArgument¶: Same as classytags.arguments.Argument but with classytags.values.IntegerValue as value_class.

class classytags.arguments.ChoiceArgument(name, choices[, default=None][, required=True] [, resolve=True])¶: An argument which validates it’s input against predefined choices.

class classytags.arguments.MultiValueArgument(name[, default=NULL][, required=True] [, max_values=None][, resolve=True])¶

An argument which accepts a variable amount of values. The maximum amount of accepted values can be controlled with the max_values argument which defaults to None, meaning there is no maximum amount of values.

default is an empty list if required is False.

resolve has the same effects as in classytags.arguments.Argument however applies to all values of this argument.

The default value for value_class is$ classytags.values.ListValue.

sequence_class¶: Class to be used to build the sequence. Defaults to classytags.utils.ResolvableList.

class classytags.arguments.MultiKeywordArgument(name[, default=None][, required=True] [, resolve=True][, max_values=None] [, splitter='='])¶

Similar to classytags.arguments.KeywordArgument but allows multiple key value pairs to be given. The will be merged into one dictionary.

Arguments are the same as for classytags.arguments.KeywordArgument and classytags.arguments.MultiValueArgument, except that default_key is not accepted and default should be a dictionary or None.

class classytags.arguments.Flag(name[, default=NULL][, true_values=None][, false_values=None] [, case_sensitive=False])¶

A boolean flag. Either true_values or false_values must be provided.

If default is not given, this argument is required.

true_values and false_values must be either a list or a tuple of strings. If both true_values and false_values are given, any value not in those sequences will raise a classytag.exceptions.InvalidFlag exception.

case_sensitive defaults to False and controls whether the values are matched case sensitive or not.

`classytags.blocks`¶

This module contains classes for Advanced Block Definition.

class classytags.blocks.BlockDefintion(alias, *names)¶

A block definition with the given alias and a sequence of names. The members of the names sequence must either be strings, classytags.blocks.VariableBlockName instances or other objects implementing at least a collect() method compatible with the one of classytags.blocks.VariableBlockName.

alias¶: The alias for this definition to be used in the tag’s kwargs.

names¶: Sequence of strings or block name definitions.

validate(options)¶: Validates this definition against an instance of classytags.core.Options by calling the validate() on all it’s names if such a method is available.

collect(parser)¶: Returns a sequence of strings to be used in the parse_until statement. This is a sequence of strings that this block accepts to be handled. The parser argument is an instance of classytags.parser.Parser.

class classytags.blocks.VariableBlockName(template, argname)¶

A block name definition to be used in classytags.blocks.BlockDefinition to implement block names that depend on the (unresolved) value of an argument. The template argument to this class should be a string with the value string substitution placeholder. For example: 'end_my_block %(value)s'. The argname argument is the name of the argument from which the value should be extracted.

validate(options)¶: Validates that the given argname is actually available on the tag.

collect(parser)¶: Returns the template substitued with the value extracted from the tag.

`classytags.core`¶

This module contains the core objects to create tags.

class classytags.core.Options(*options, **kwargs)¶

Holds the options of a tag. options should be a sequence of classytags.arguments.Argument subclasses or strings (for breakpoints). You can give they keyword argument blocks to define a list of blocks to parse until. You can specify a custom argument parser by providing the keyword argument parser_class.

all_argument_names¶: A list of all argument names in this tag options. Used by classytags.blocks.VariableBlockName to validate it’s definition.

get_parser_class()¶: Returns classytags.parser.Parser or a subclass of it.

bootstrap()¶: An internal method to bootstrap the arguments. Returns an instance of classytags.utils.StructuredOptions.

parse(parser, token):: An internal method to parse the template tag. Returns a tuple (arguments, blocks).

class classytags.core.TagMeta¶: The metaclass of classytags.core.Tag which ensures the tag has a name attribute by setting one based on the classes name if none is provided.

class classytags.core.Tag(parser, token)¶

The Tag class is nothing other than a subclass of django.template.Node which handles argument parsing in it’s __init__() method rather than an external function. In a normal use case you should only override name, options and render_tag().

Note

When registering your template tag, register the class object, not an instance of it.

name¶: The name of this tag (for use in templates). This attribute is optional and if not provided, the un-camelcase class name will be used instead. So MyTag becomes my_tag.

options¶: An instance of classytags.core.Options which holds the options of this tag.

__init__(parser, token):: Warning

This is an internal method. It is only documented here for those who would like to extend django-classy-tags.

This is where the arguments to this tag get parsed. It’s the equivalent to a compile function in Django’s standard templating system. This method does nothing else but assing the kwargs and blocks attributes to the output of options.parse() with the given parser and token.

render(context)¶: Warning

This is an internal method. It is only documented here for those who would like to extend django-classy-tags.

This method resolves the arguments to this tag against the context and then calls render_tag() with the context and those arguments and returns the return value of that method.

render_tag(context[, **kwargs])¶: The method used to render this tag for a given context. kwargs is a dictionary of the (already resolved) options of this tag as well as the blocks (as nodelists) this tag parses until if any are given. This method should return a string.

`classytags.exceptions`¶

This module contains the custom exceptions used by django-classy-tags.

exception classytags.exceptions.BaseError¶: The base class for all custom excpetions, should never be raised directly.

exception classytags.exceptions.ArgumentRequiredError(argument, tagname)¶: Gets raised if an option of a tag is required but not provided.

exception classytags.exceptions.InvalidFlag(argname, actual_value, allowed_values, tagname)¶: Gets raised if a given value for a flag option is neither in true_values nor false_values.

exception classytags.exceptions.BreakpointExpected(tagname, breakpoints, got)¶: Gets raised if a breakpoint was expected, but another argument was found.

exception classytags.exceptions.TooManyArguments(tagname, extra)¶: Gets raised if too many arguments are provided for a tag.

`classytags.helpers`¶

This modules contains helper classes to make building template tags even easier.

class classytags.helpers.AsTag¶

A helper tag base class to build ‘as varname’ tags. Note that the option class still has to contain the ‘as varname’ information. This tag will use the last argument in the options class to set the value into the context.

This class implements the method classytags.helpers.AsTag.get_value() which gets the context and all arguments except for the varname argument as arguments. It should always return the value this tag comes up with, the class then takes care of either putting the value into the context or returns it if the varname argument is not provided.

Note

You should not override the render_tag() method of this class.

get_value_for_context(context, **kwargs):

New in version 0.5.

Should return the value of this tag if used in the ‘as varname’ form. By default this method just calls get_value and returns that.

You may want to use this method if you want to suppress exceptions in the ‘as varname’ case.

get_value(context, **kwargs)¶: Should return the value of this tag. The context setting is done in the classytags.core.Tag.render_tag() method of this class.

class classytags.helpers.InclusionTag¶

A helper class for writing inclusion tags (template tags which render a template).

Note

You should not override the render_tag() method of this class.

template¶: The template to use if get_template() is not overridden.

push_context¶: New in version 0.5.2.

By default, this is False. If it’s set to True the context will be pushed before rendering the included template, preventing context pollution.

get_template(context, **kwargs)¶: This method should return a template (path) for this context and arguments. By default returns the value of template.

get_context(context, **kwargs)¶: Should return the context (as a dictionary or an instance of django.template.Context or a subclass of it) to use to render the template. By default returns an empty dictionary.

`classytags.parser`¶

The default argument parser lies here.

class classytags.parser.Parser(options)¶

The default argument parser class. It get’s initialized with an instance of classytags.utils.StructuredOptions.

options¶: The classytags.utils.StructuredOptions instance given when the parser was instantiated.

parser¶: The (template) parser used to parse this tag.

bits¶: The split tokens.

tagname¶: Name of this tag.

kwargs¶: The data extracted from the bits.

blocks¶: A dictionary holding the block nodelists.

arguments¶: The arguments in the current breakpoint scope.

current_argument¶: The current argument if any.

todo¶: Remaining bits. Used for more helpful exception messages.

parse(parser, token)¶: Parses a token stream. This is called when your template tag is parsed.

handle_bit(bit)¶: Handle the current bit (token).

handle_next_breakpoint(bit)¶: The current bit is the next breakpoint. Make sure the current scope can be finished successfully and shift to the next one.

handle_breakpoints(bit)¶: The current bit is a future breakpoint, try to close all breakpoint scopes before that breakpoint and shift to it.

handle_argument(bit)¶: The current bit is an argument. Handle it and contribute to kwargs.

parse_blocks()¶: Parses the blocks this tag wants to parse until if any are provided.

finish()¶: After all bits have been parsed, finish all remaining breakpoint scopes.

check_required()¶: A helper method to check if there’s any required arguments left in the current breakpoint scope. Raises a classytags.exceptions.ArgumentRequiredError if one is found and contributes all optional arguments to kwargs.

`classytags.utils`¶

Utility classes and methods for django-classy-tags.

class classytags.utils.NULL¶: A pseudo type.

class classytags.utils.TemplateConstant(value)¶

A constant pseudo template variable which always returns it’s initial value when resolved.

literal¶: Used by the classytags.blocks.VariableBlockName to generate it’s final name.

class classytags.utils.StructuredOptions(options, breakpoints)¶

A helper class to organize options.

options¶: The arguments in this options.

breakpoints¶: A copy of the breakpoints in this options

blocks¶: A copy of the list of tuples (blockname, alias) of blocks of this tag.

current_breakpoint¶: The current breakpoint.

next_breakpoint¶: The next breakpoint (if there is any).

shift_breakpoint()¶: Shift to the next breakpoint and update current_breakpoint and next_breakpoint.

get_arguments()¶: Returns a copy of the arguments in the current breakpoint scope.

class classytags.utils.ResolvableList(item)¶: A subclass of list which resolves all it’s items against a context when it’s resolve method gets called.

classytags.utils.get_default_name(name)¶: Turns ‘CamelCase’ into ‘camel_case’.

`classytags.values`¶

class classytags.values.StringValue(var)¶

errors¶: A dictionary holding error messages which can be caused by this value class. Defaults to an empty dictionary.

value_on_error¶: The value to use when the validation of a input value fails in non-debug mode. Defaults to an empty string.

var¶: The variable wrapped by this value instance.

resolve(context)¶: Resolve var against context and validate it by calling the clean() method with the resolved value.

clean(value)¶: Validates and/or cleans a resolved value. This method should always return something. If validation fails, the error() helper method should be used to properly handle debug modes.

error(value, category)¶: Handles an error in category caused by value. In debug mode this will cause a django.template.TemplateSyntaxError to be raised, otherwise a TemplateSyntaxWarning is called and value_on_error is returned. The message to be used for both the exception and the warning will be constructed by the message in errors if category is in it. The value can be used as a named string formatting parameter.

class classytags.values.StrictStringValue(var)¶: Same as StringValue but enforces that the value passed to it is a string (instance of basestring).

class classytags.values.IntegerValue(var)¶

Subclass of StringValue.

clean(value)¶: Tries to convert the value to an integer.

class classytags.values.ListValue(value)¶

Subclass of StringValue and list.

Appends the initial value to itself in initialization.

resolve(context)¶: Resolves all items in itself against context and calls clean() with the list of resolved values.

class classytags.values.DictValue(dict)¶

Subclass of StringValue and dict.

resolve(context)¶: Resolves all values against context and calls clean() with the resolved dictionary.

Extending django-classy-tags¶

You can extend django-classy-tags by writing your own subclasses of classytags.arguments.Argument which behave to your needs. If that does not cover your needs, you may also subclass classytags.core.Options and set a custom argument parser, which should subclass classytags.parser.Parser.

Creating a custom argument class¶

The most important method in this class for customization is classytags.arguments.Argument.parse(), so let’s have a closer look at it. It takes exactly four arguments, which are as follows:

parser: An instance of django.template.Parser.
token: The current token as a string.
tagname: The name of the tag being handled.
kwargs: The dictionary of already parsed arguments.

The parse method must return a boolean value:

If your method returns True, it means it has successfully handled the provided token. Your method has to add content to kwargs itself. The parser does not do that! When you return True, the next token will also try to get parsed by this argument’s parse method.
If your method returns False, it means it has not handled this token and the next argument class in the stack should be used to handle this token. Usually you would return False when your argument’s name is already in kwargs. Obviously this only applies to single-value arguments.

So let’s look at the standard classytags.arguments.Argument.parse():

def parse(self, parser, token, tagname, kwargs):
    """
    Parse a token.
    """
    if self.name in kwargs:
        return False
    else:
        kwargs[self.name] = self.parse_token(parser, token)
        return True

First it checks if the name is already in kwargs. If so, return False and let the next argument handle this token. Otherwise do some checking if we should resolve this token or not and add it to kwargs. Finally return True.

You might notice the classytags.arguments.Argument.parse_token() method used there. This method is responsible for turning an token into a template variable, a filter expression or any other object which allows to be resolved against a context. The one in classytags.arguments.Argument looks like this:

def parse_token(self, parser, token):
    if self.resolve:
        return parser.compile_filter(token)
    else:
        return TemplateConstant(token)

Cleaning arguments¶

If all you want to do is clean arguments or enforce a certain type, you can just change the classytags.arguments.Argument.value_class of your subclass of classytags.arguments.Argument to a subclass of classytags.values.StringValue which implements a clean method in which you can check the type and/or cast a type on the value. For further information on value classes, see classytags.values.

Custom argument parser¶

The argument parser was written with extensibility in mind. All important steps are split into individual methods which can be overwritten. For information about those methods, please refer to the reference about classytags.parser.Parser.

To use a custom parser, provide it as the parser_class keyword argument to classytags.core.Options.

Note

Each time your tag gets parsed, a new instance of the parser class gets created. This makes it safe to use self.

Example¶

Let’s make an argument which, when resolved, returns a template.

First we need a helper class which, after resolving loads the template specified by the value:

from django.template.loader import get_template

class TemplateResolver:
    def __init__(self, real):
        self.real = real

    def resolve(self, context):
        value = self.real.resolve(context)
        return get_template(value)

Now for the real argument:

from classytags.arguments import Argument

class TemplateArgument(Argument):
    def parse_token(self, parser, token):
        real = super().parse_token(parser, token)
        return TemplateResolver(real)

Contribute to django-classy-tags¶

As with (hopefully) any open source project, contribution is very welcome.

Review the documentation¶

A great way to contribute to django-classy-tags, which requires absolutely no coding skills and can be done by anyone who knows English, is to read this documentation and inform me about any mistakes in the documentation. Also any suggestion on how to write the documentation clearer and easier to understand would be greatly appreciated.

If you use django-classy-tags yourself as a developer and found certain things in the documentation to be unclear to you or you would like to have more in depth documentation on some features, please also tell me so I can make it easier for people to use this project.

Spread the word¶

Tell people about this project! The more people use it the higher the chance the quality of this project will increase.

Improve the test suite¶

There is a handy little test framework located in the testdata folder. It allows automated testing of django-classy-tags implementation against builtin Django tags. Have a look at the existing tags and feel free to add more!

Also adding good old unit tests is a great way to help too.

Running the test suite¶

From the root folder of your django-classy-tags checkout, run ./runtests.sh.

Write code¶

Want a feature implemented or a bug eliminated? The quickest way to get there is to write the code yourself and get it back to me.
