Unobtrusive jinja2 integration in Django
Tested with Django 1.8, 1.11 and 2.0 and the latest minor versions of Python 2
and 3 (Django 2.0 only supports Python 3).
If you like ``djinga`` and are looking for a way to thank me and/or encourage
future development, here is my BTC or BCH donation address:
``1EwENyR8RV6tMc1hsLTkPURtn5wJgaBfG9``.
Why djinga ?
------------
Simply because no other jinja2 integration app for django met the requirements
of a perfectionist django developer.
Djinga enables you to:
- Use django and jinja2 templates in the same project with dynamic selection
of the template engine to use
- Extend and include jinja2 templates from django ones and vice-versa
- Insert django template code into jinja2 templates
- Turn any django templatetag or python function into jinja2 filters or
globals using decorators ... and without creating import loops
- Extract translation strings from jinja2 templates with django's
``makemessages`` management command
- Access useful jinja2 extensions, such as HTML compression, most django
template's native tags and context processors
Usage
-----
- Install djinga using the method of your choice
- Add 'djinga' to your INSTALLED_APPS
- Set the ``TEMPLATE`` setting as::
TEMPLATES = [
{
'BACKEND': 'djinga.backends.djinga.DjingaTemplates',
'DIRS': ['your/first/template/directory',
'your/second/template/directory'],
'OPTIONS': {
...
},
},
]
- Add the relevant `options`_ for jinja2 and djinga
How it works
------------
By default, a template will be rendered using Django's built-in template engine
if it has a .html, .htm, .djhtml or .djhtm file extension. If it has a .jjhtml
or .jjhtm file extension, it will be rendered by Jinja2, using the setting
values provided in django's setting module.
Options
-------
Simply add the following options to the ``'OPTIONS'`` section of the
``TEMPLATES`` item matching the djinga backend::
TEMPLATES = [
{
'BACKEND': 'djinga.backends.djinga.DjingaTemplates',
'OPTIONS': {
'option1': 'value1',
'option2': {'key1': 'val1',
'key2': 'val2'},
...
},
},
]
dj_exts
A list or tuple of file extensions (with or without the leading dot) for
templates that should be rendered with Django's internal template engine.
Defaults to ``('html', 'htm', 'jjhtml', 'jjhtm')``
jj_exts
A list or tuple of the file extensions (with or without the leading dot) for
templates that should be rendered with Jinja2.
Defaults to ``('jjhtml', 'jjhtm')``
condition
A function taking as sole argument the path of the template file and
returning True if the file should be rendered with Jinja2. Defaults to a
function returning True if the extension is in JINJA2_JJ_EXTS
extensions
A tuple or list of extensions to be loaded by jinja2 (as python objects or
paths to the python objects). `Some extensions`_ are shipped with
djinga under ``djinga.ext.*``.
globals
The jinja2 globals as a dictionary.
filters
The jinja2 filters as a dictionary.
load_from
A tuple or list of module paths to load globals and filters from. This
advantageously complements or replaces the ``globals`` and
``filters`` options. See `Adding globals and filters`_ for details.
any_jinja2_option
Any other argument to construct a jinja2 environment may be provided.
Jinja2 extensions
-----------------
Djinga comes with several Jinja2 extensions:
djinga.ext.static
Provides a ``{% static 'path' %}`` tag to refer to Django's staticfiles
directory
djinga.ext.css
Provides a ``{% css 'rel/path/to/file.css' %}`` tag that generates a
HTML link element refering to the css file located at a relative path in
a css directory. The css directory's path can be defined relatively to
Django's staticfiles directory through the setting JINJA2_STATIC_CSS
djinga.ext.js
Same as djinga.ext.css but generates a HTML script element refering to a
javascript file. The js directory's relative path can be set through the
setting JINJA2_STATIC_JS
djinga.ext.media
Simply concatenates django's MEDIA_URL to the argument provided
djinga.ext.django
From `a PR on coffin`_.
Provides a ``{% django %}{% enddjango %}`` tag to include django template
language in a jinja2 template. For this tag to work, the
``django.core.context_processors.request`` context processor must be
enabled.
djinga.ext.csrf_token
From coffin_
Provides a Django-like ``{% csrf_token %}`` tag.
djinga.ext.url
Provides a tag for URL reversing, similar to the django templates one.
djinga.ext.htmlcompress.HTMLCompress / SelectiveHTMLCompress
Based on `Armin Ronacher's version`_.
Eliminates useless whitespace at template compilation time without extra
overhead. Since version 2.0, it also deals with inline javascript.
Django template tags
--------------------
The following tags are automatically made available in any django template:
extends
Overrides the standard ``{% extends %}`` tag and enables it to refer to
jinja2 files as well as normal django template files. While the template
engine for the current file remains Django's one, the template engine for
the extended file can be either Jinja2 or Django, depending on the file
extension (in ``dj_exts`` or ``jj_exts``)
Adding globals and filters
--------------------------
A straightforward way to add globals and filters and make them available from
your Jinja2 templates is to add them to the ``globals`` or the ``filters``
options in the settings module.
However, this is not always convenient nor possible (import loops), and djinga
therefore provides a way to ease this process, through the ``jj_global`` and
``jj_filter`` decorators in combination with the ``load_from`` option.
Basically, the decorators mark the functions as Jinja2 globals or filters,
while the setting (a list of module paths) indicates djinga where to look for
them.
A short example is better than long explanations, so here we go.
This::
[my_app/my_module.py]
from djinga.register import jj_filter, jj_global
@jj_global
def my_tag(*args, **kw):
pass
@jj_filter
def my_filter(*args, **kw)
pass
[settings.py] # django 1.8+
TEMPLATES = [
{
'BACKEND': 'djinga.backends.djinga.DjingaTemplates',
'OPTIONS': {
'load_from': ('my_app.my_module',),
},
},
]
[settings.py] # django < 1.8
JINJA2_LOAD_FROM = (
'my_app.my_module',
)
is equivalent to this::
[my_app/my_module.py]
def my_tag(*args):
pass
def my_filter(*args, **kw)
pass
[settings.py] # django 1.8+
from my_app.my_module import my_tag, my_filter
TEMPLATES = [
{
'BACKEND': 'djinga.backends.djinga.DjingaTemplates',
'OPTIONS': {
'globals': {'my_tag': my_tag},
'filters': {'my_filter': my_filter},
},
},
]
[settings.py] # django < 1.8
from my_app.my_module import my_tag, my_filter
JINJA2_GLOBALS = {'my_tag': my_tag}
JINJA2_FILTERS = {'my_filter': my_filter}
...with the significant advantage of not requiring a possibly issue-prone
``import`` statement in the ``settings`` module.
The ``jj_global`` and ``jj_filter`` decorators are compatible with any of the
`Jinja2 built-in decorators`_. They do not affect the behavior nor the
signature of the decorated function, so you can use it normally (as a normal
Django template tag or filter, for example).
The collected globals and filters are appended to the ones already specified
in ``globals`` and ``filters``.
``makemesssages`` management command
------------------------------------
Adapted from coffin_.
Djinga overrides the Django ``makemessages`` core management command to include
the specific Jinja2 translation tags and ensure the strings marked for
translation in Jinja2 templates appear in the translations dictionary.
