}
WARNING: Be carefull with serialization of model objects. As you can see in example, password hash has been serialized.
json_encode
~~~~~~~~~~~
json_encode(data)
Serialize python object into JSON string.
The main issues with django's default json serializer is that properties that
had been added to an object dynamically are being ignored (and it also has
problems with some models).
json_response
~~~~~~~~~~~~~
json_response(data)
Serialize python object into JSON string and return HttpResponse with correct content_type (application/json)
json_template
~~~~~~~~~~~~~
json_template(data, template_name, template_context)
Render template, add it for serialization data, serialize data into JSON string and return HttpResponse with correct content_type.
Context processors
------------------
useful_constants
~~~~~~~~~~~~~~~~
If you want use True, False, None in django templates, add line to TEMPLATE_CONTEXT_PROCESSORS in settings.py::
'misc.context_processors.useful_constants',
Example, A = True, B = False, C = None, D - undefined::
{% if A == True %}A is True{% endif %}
{% if A == False %}A is False{% endif %}
{% if A == None %}A is None{% endif %}
{% if B == True %}B is True{% endif %}
{% if B == False %}B is False{% endif %}
{% if B == None %}B is None{% endif %}
{% if C == True %}C is True{% endif %}
{% if C == False %}C is False{% endif %}
{% if C == None %}C is None{% endif %}
{% if D == True %}D is True{% endif %}
{% if D == False %}D is False{% endif %}
{% if D == None %}D is None{% endif %}
Will produce output::
A is True
B is False
C is None
D is None
Views utils
-----------
server_error
~~~~~~~~~~~~
misc.views.server_error(request)
Put server_error as your handler500 in urls.py and add templates/errors/500.html ::

decorator to_template or render_to

@to_template
def test2(request, template_name='test.html'):
return {'test': 100, 'TEMPLATE': template_name}
HttpResponseReload
~~~~~~~~~~~~~~~~~~
utils.HttpResponseReload(request)
Reload current page. ::
def simple_view(request, form_class=CommentForm, template_name='some_template.html'):

if form.valid():

return HttpResponseReload(request)
return render(template_name, {'form': form})
