Re: Using FormMixin with DetailView

Hello,

could you show us the relevant part of your urls.py file? I suspect view parameters to cause the trouble but I'd like to be sure.

Best,
Gergely

I am on the exact same situation as the one described in the documentation here: https://docs.djangoproject.com/en/1.7/topics/class-based-views/mixins/#using-formmixin-with-detailview 

I have followed the documentation but I get the following exception:

__init__() takes exactly 1 argument (3 given)

Request Method:	GET
Request URL:	http://localhost:8000/post/5144752345317376/
Django Version:	1.6.11
Exception Type:	TypeError
Exception Value:	__init__() takes exactly 1 argument (3 given)
Exception Location:	...app/sitepackages/django/core/handlers/base.py in get_response, line 11

I think the only location where I might need something different is my urls.py... Here is the complete code:

class PostView(BlogMixin,DetailView):
    """ A view for displaying a single post """
    template_name = 'post.html'
    model = Post
    def get_context_data(self, **kwargs):
        context = super(PostView, self).get_context_data(**kwargs)
        context['form'] = CommentForm()
        return context
   
class PostDetailView(View):
    print "HERE   ------------ "


    def get(self, request, *args, **kwargs):
        print "GET   ------------ "
        view = PostView.as_view()
        return view(request, *args, **kwargs)


    def post(self, request, *args, **kwargs):
        print "POST   ------------ "
        view = PostComment.as_view()
        return view(request, *args, **kwargs)


class PostComment(  SingleObjectMixin , FormView):
    template_name = 'post.html'
    form_class = CommentForm
    model = Post


    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        return super(PostComment, self).post(request, *args, **kwargs)


    def get_success_url(self):
        return reverse('post-detail', kwargs={'pk': self.object.pk})

class BlogMixin(object):

    """

    Basic mixin for all the views. Update the context with additional

    information that is required across the whole site, typically

    to render base.html properly

    """

    def get_context_data(self, *args, **kwargs):

        context = super(BlogMixin, self).get_context_data(*args, **kwargs)

        blog = Blog.get_unique()

        context.update({

            'blog': blog,

            'active_user': users.get_current_user(),

            'is_admin': users.is_current_user_admin()

        })

        return context

urls.py:

    url(r'^post/(?P<pk>[\d]+)/$', views.PostDetailView., name="post-detail"),

Before the exception, 'HERE ------" is printed, but no GET or POST
