Django: Redirect to current article after comment post

Question

I am trying to use comments application in my project.

I tried to use code ({% render_comment_form for event %}), shown in the documentation here: Django comments

Answer 1

Take a look at "Django-1.4/django/contrib/comments/templates/comments/" folder and you will see in the "form.html" file, there is the line

{% if next %}<div><input type="hidden" name="next" value="{{ next }}" /></div>{% endif %}

Therefore, in the Article-Detail view, you can include the "next" attribute in the context data, and then the comment framework will do the rest

class ArticleDetailView(DetailView):
    model = Article
    context_object_name = 'article'

    def get_context_data(self, **kwargs):
        context = super(ArticleDetailView, self).get_context_data(**kwargs)

        context['next'] = reverse('blogs.views.article_detail_view', 
            kwargs={'pk':self.kwargs['pk'], 'slug': self.kwargs['slug']})
        return context

Update: Now have the option to redirect as part of the comment form: see http://docs.djangoproject.com/en/dev/ref/contrib/comments/#redirecting-after-the-comment-post

Answer 3

I will show you how I resolved it in my blog, so you could do something similar. My comments are for Entry model in entries application.

First add new method for your Entry (like) object.

def get_absolute_url(self):
    return "/%i/%i/%i/entry/%i/%s/" % (self.date.year, self.date.month, self.date.day, self.id, self.slug)

It generates url for entry objects. URL example: /2009/12/12/entry/1/lorem-ipsum/

To urls.py add 1 line:

(r'^comments/posted/$', 'smenteks_blog.entries.views.comment_posted'),

So now you should have at least 2 lines for comments in your urls.py file.

(r'^comments/posted/$', 'smenteks_blog.entries.views.comment_posted'),
(r'^comments/', include('django.contrib.comments.urls')),

For entries (like) application in views.py file add function:

from django.contrib.comments import Comment #A
...
def comment_posted(request):
    if request.GET['c']:
        comment_id = request.GET['c'] #B
        comment = Comment.objects.get( pk=comment_id )
        entry = Entry.objects.get(id=comment.object_pk) #C
        if entry:
            return HttpResponseRedirect( entry.get_absolute_url() ) #D
    return HttpResponseRedirect( "/" )    

• A) Import on top of file to have access for comment object,
• B) Get comment_id form REQUEST,
• C) Fetch entry object,
• D) Use get_absolute_url method to make proper redirect.

Now:

• Post button in comment form on entry site redirects user on the same (entry) site.
• Post button on preview site redirects user on the proper (entry) site.
• Preview button in comment form on entry site and on preview site redirects user on preview site
• Thankyou page is not more in use (That page was quite annoying in my opinion).

Next thing good to do is to override preview.html template:

• Go to django framework dir, under linux it could by /usr/share/pyshared/.
• Get original preview.html template from DJANGO_DIR/contrib/comments/templates/comments/preview.html
• Copy it to templates direcotry in your project PROJECT_DIR/templates/comments/entries_preview.html
• From now on, it shoud override default template, You can change extends in this way: {% extends "your_pagelayout.html" %} to have your layout and all css files working.

Simplify Django’s Free Comments Redirection

Answer 5

This is a really simple redirect to implement. It redirects you back to the page where the comment was made.

When a comment is posted, the url comments/posted/ calls the view comment_posted which then redirects back to the referer page.

Be sure to replace [app_name] with your application name.

views.py

from urlparse import urlsplit

def comment_posted( request ):
    referer = request.META.get('HTTP_REFERER', None)
    if referer is None:
        pass
    try:
        redirect_to = urlsplit(referer, 'http', False)[2]
    except IndexError:
       pass
    return HttpResponseRedirect(redirect_to)

urls.py

( r'^comments/posted/$', '[app_name].views.comment_posted' ),
