A package that makes possible the integration of Jinja2 in Django, in a clean way.
Djinja tries to integrate Jinja2 in Django. The aim is to replace completely the Django’s template system, including administration.
Currently, the following templating modules have been written and are working:
- Django administration
- Django Debug Toolbar
In a near future, you could convert Django templates syntax to Jinja2 syntax, isn’t awesome?
If you have ideas please let us know.
Add the djinja directory to your Python path.
Add the following template loader (AT TOP OF TEMPLATE_LOADERS) to your project’s settings.py file:
Tying into template loaders allows Djinja to manage automatically ALL the templates with Jinja2 (including Django templates)
Note: If you don’t install djinja.contrib.admin when you try to access to the Django administration you will get an error, this is caused because the Django administration templates are not adapted for Jinja2.
That’s all! ;)
IMPORTANT: You have to adapt your website templates to Jinja2 or you will get an error when rendering (until the djinja converser is ready).
Custom filters and extensions
Djinja uses the same templatetag library approach as Django, meaning your app has a templatetags directory, and each of it’s modules represents a “template library”, providing new filters and tags.
A custom Library class in djinja.template.Library can be used to register Jinja-specific components.
Djinja can automatically make your existing Django filters usable in Jinja, but not your custom tags - you need to rewrite those as Jinja extensions manually.
Example for a Jinja-enabled template library:
from djinja import template register = template.Library() register.filter(plenk, 'plenk') # Filter function register.extension(FooExtension) # Jinja version of the tag register.tag(my_function_name) # A global function/object register.set(a='hello') # A context variable (named a)
You may also define additional extensions, filters, tests, and globas via your settings.py:
JINJA2_FILTERS = ( 'path.to.myfilter', ) JINJA2_EXTENSIONS = ( 'jinja2.ext.do', )
Djinja can render HAML pages (having installed HamlPy - https://github.com/jessemiller/HamlPy), and is as just simple as put the .haml extension to your template and adding 'djinja.template.extensions.haml' in the JINJA2_EXTENSIONS variable of your settings:
JINJA2_EXTENSIONS = ( ... 'djinja.template.extensions.haml', ... )
HAML templates can also include,extend,etc HTML templates and viceversa.
For install the Django administration Jinja2 templating just add 'djinja.contrib.admin', before ‘django.contrib.admin’ in your INSTALLED_APPS in settings.py.
INSTALLED_APPS = ( ... 'djinja.contrib.admin', 'django.contrib.admin', ... )

With Jinja2 (Djinja)
Requests per second: 202.16 [#/sec] (mean) Time per request: 4.947 [ms] (mean)
3x performance using Jinja2 instead of Django templating in administration
Django Debug Toolbar
For install the Django Debug Toolbar Jinja2 templating just add 'djinja.contrib.debug_toolbar', before ‘debug_toolbar’ in your INSTALLED_APPS in settings.py.
INSTALLED_APPS = ( ... 'djinja.contrib.debug_toolbar', 'debug_toolbar', ... )
