Re: Using FormMixin with DetailView

Forgot to add, the full backtrace would be helpful, too. It should be present on the same error page.

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
