Question

I am working on blog project in which I added an add post which add post now I want only the superuser can add post and that page is visible only to superuser.
1st Method
Views.py
class AddPostView(CreateView):
model = Post
template_name = 'MainSite/add_post.html'
fields = '__all__'
this is my current view I am able to achieve authenticate for superuser using 2nd method
2nd Method
class AddPostView(View):
def get(self,request):
if request.user.is_superuser == True:
return render(...)
else:
pass
How can I achieve the same result using 1st method.I tried using LoginRequiredMixin but nothing is happening . I just import LoginRequiredMixin and use it like this .
class Addpost(CreateView,LoginRequiredMixin):
...
Thanks in advance and advice will be helpful.

Answer 1

You can work with a UserPassesTestMixin mixin [Django-doc]:
from django.contrib.auth.mixins import UserPassesTestMixin
class AddPostView(UserPassesTestMixin, CreateView):
# …
def test_func(self):
return self.request.user.is_superuser
# …
You can encapsulate this in a mixin:
from django.contrib.auth.mixins import UserPassesTestMixin
class AdminRequiredMixin(UserPassesTestMixin):
def test_func(self):
return self.request.user.is_superuser
and then use this mixin:
class AddPostView(AdminRequiredMixin, CreateView):
# …
def test_func(self):
return self.request.user.is_superuser
# …
Mixins should be put before the actual view in the inheritance hierarchy: otherwise these appear after the view in the method resolution order (MRO), and thus likely will not override the behavior (correctly).

class AddPostView(CreateView,LoginRequiredMixin):
model = Post
template_name = 'MainSite/add_post.html'
fields = '__all__'
def dispatch(self, request, *args, **kwargs):
if request.user.is_anonymous:
return redirect_to_login(self.request.get_full_path(), self.get_login_url(), self.get_redirect_field_name())
elif request.user.is_superuser:
return render(.....)
else
return super(AddPostView, self).dispatch(request, *args, **kwargs)

Use method_decorator and user_passes_test to achieve this
from django.views.generic import View
from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import user_passes_test
class AddPostView(View):
#method_decorator(user_passes_test(lambda u: u.is_superuser))
def post(self, *args, **kwargs):
pass
