This module is a collection of helper classes generally used in view functions/classes. All the shortcuts are available
in the module django.shortcuts.
render
Params:
def render(request, template_name, context=None, content_type=None, status=None, using=None)Shortcut for:
content = loader.render_to_string(template_name, context, request, using=using)
return HttpResponse(content, content_type, status)There is also render_to_response, the only difference is that it does not pass the request to the context.
redirect
Params:
def redirect(to, *args, **kwargs):Returns an HttpResponseRedirect (or HttpResponsePermanentRedirect) to the appropriate URL for the arguments passed.
The arguments could be:
- A model: the model’s
get_absolute_url()function will be called. - A view name, possibly with arguments:
urls.reverse()will be used to reverse-resolve the name. - A URL, which will be used as-is for the redirect location.
Shortcut for:
def post_view(request, post_id):
post = Post.objects.get(pk=post_id)
return redirect(post)
# equivalent to: return HttpResponseRedirect(post.get_absolute_url())
def post_view(request, post_id):
return redirect('post_details', id=post_id)
# equivalent to: return HttpResponseRedirect(reverse('post_details', args=(post_id, )))
def relative_url_view(request):
return redirect('/posts/archive/')
# equivalent to: return HttpResponseRedirect('/posts/archive/')
def absolute_url_view(request):
return redirect('https://simpleblog.com/posts/archive/')
# equivalent to: return HttpResponseRedirect('https://simpleblog.com/posts/archive/')See more in this post about the redirect function.
get_object_or_404
Params:
def get_object_or_404(klass, *args, **kwargs):Shortcut for:
try:
return Model.objects.get(pk=1)
except Model.DoesNotExist:
raise Http404()get_list_or_404
Params:
def get_list_or_404(klass, *args, **kwargs):Shortcut for:
obj_list = list(Model.objects.filter(title='test'))
if not obj_list:
raise Http404()
return obj_listresolve_url
This one is actually used by the redirect shortcut. It will do basically the same thing, except to perform the actual redirect.
Params:
def resolve_url(to, *args, **kwargs):The arguments could be:
- A model: the model’s
get_absolute_url()function will be called. - A view name, possibly with arguments:
urls.reverse()will be used to reverse-resolve the name. - A URL, which will be returned as-is.
