Hi,
Inside your "post" method, you have this line:
context = super(AccountProfilesView, self).post(request, *args, **kwargs)
in that case "context" is a HttpResponse object[0]. May be, from the name
you use for the variable, you think this is a simple dict as those used to
pass context to render functions; it is not.
You can use HttpResponse as a dictionary to put HTTP headers in the
response [1], so line 184 is setting an HTTP header with a value of the
HTML to render the form; that is not what you want.
You have to remove that line and create your context with something like:
context = {}
And you have to return an HttpResponse object, probably by calling one of
the render functions [2].
