How do I use Django templates without the rest of Django?

Solution 1:

The solution is simple. It's actually well documented, but not too easy to find. (I had to dig around -- it didn't come up when I tried a few different Google searches.)

The following code works:

>>> from django.template import Template, Context
>>> from django.conf import settings
>>> settings.configure()
>>> t = Template('My name is {{ my_name }}.')
>>> c = Context({'my_name': 'Daryl Spitzer'})
>>> t.render(c)
u'My name is Daryl Spitzer.'

See the Django documentation (linked above) for a description of some of the settings you may want to define (as keyword arguments to configure).

Solution 2:

Jinja2 syntax is pretty much the same as Django's with very few differences, and you get a much more powerfull template engine, which also compiles your template to bytecode (FAST!).

I use it for templating, including in Django itself, and it is very good. You can also easily write extensions if some feature you want is missing.

Here is some demonstration of the code generation:

>>> import jinja2
>>> print jinja2.Environment().compile('{% for row in data %}{{ row.name | upper }}{% endfor %}', raw=True) 
from __future__ import division
from jinja2.runtime import LoopContext, Context, TemplateReference, Macro, Markup, TemplateRuntimeError, missing, concat, escape, markup_join, unicode_join
name = None

def root(context, environment=environment):
    l_data = context.resolve('data')
    t_1 = environment.filters['upper']
    if 0: yield None
    for l_row in l_data:
        if 0: yield None
        yield unicode(t_1(environment.getattr(l_row, 'name')))

blocks = {}
debug_info = '1=9'

Solution 3:

Any particular reason you want to use Django's templates? Both Jinja and Genshi are, in my opinion, superior.

If you really want to, then see the Django documentation on settings.py. Especially the section "Using settings without setting DJANGO_SETTINGS_MODULE". Use something like this:

from django.conf import settings
settings.configure (FOO='bar') # Your settings go here

Solution 4:

I would also recommend jinja2. There is a nice article on django vs. jinja2 that gives some in-detail information on why you should prefere the later.

Solution 5:

According to the Jinja documentation, Python 3 support is still experimental. So if you are on Python 3 and performance is not an issue, you can use django's built in template engine.

Django 1.8 introduced support for multiple template engines which requires a change to the way templates are initialized. You have to explicitly configure settings.DEBUG which is used by the default template engine provided by django. Here's the code to use templates without using the rest of django.

from django.template import Template, Context
from django.template.engine import Engine

from django.conf import settings
settings.configure(DEBUG=False)

template_string = "Hello {{ name }}"
template = Template(template_string, engine=Engine())
context = Context({"name": "world"})
output = template.render(context) #"hello world"
