Question

i have a Reply class:

class Reply(models.Model):
    reply_to = models.ForeignKey(New)
    creator = models.ForeignKey(User)
    reply = models.CharField(max_length=140,blank=False)

a replay form:

class ReplyForm(ModelForm):
class Meta:
      model = Reply
      fields = ['reply']

where New is the Post class (containing users posts)
and a view

def save_reply(request):
   #u = New.objects.get(pk=id)
if request.method == 'POST':

    form = ReplyForm(request.POST)
    if form.is_valid():
       new_obj = form.save(commit=False)
       new_obj.creator = request.user
       new_obj.reply_to = form.reply_to
     #  reply_to_id = u
       new_post = New(2) #this works hardcoded, but how can i get the blog New post #id, as a parameter, instead?
       new_obj.reply_to = new_post
       new_obj.save()
       return HttpResponseRedirect('.')    

else:
form = ReplyForm()
return render_to_response(‘replies/replies.html’, {
‘form’: form,
},
context_instance=RequestContext(request))

where created_by belongs to New class and represents the creator of the post (which is to be replied)

how can i assign the current post to the reply under it?

thanks in advance!

Answer 1

I may have missed something, but reply_to needs an instance of the New model. New.id doesn’t look like one to me?

new_obj.reply_to = New.id

Do you have an instance of the New model available at that point that you can assign?

ah, I see you’ve tweaked the question

If you don’t have an instance of the New model, you’ll need to create one

new_post = New(whatever, goes, here)
new_post.save()

Then assign it to reply_to

new_obj.reply_to = new_post

Or similar.

edit

Without knowing exactly that ReplyForm looks like I’m guessing a bit, but presumably it’s based on the Reply object, letting the user select the reply_to field somehow or other?

Assuming that the form’s reply_to variable is populated & correct I think you should just be able to do:

form = ReplyForm(request.POST)
if form.is_valid():
   new_obj = form.save(commit=False)
   new_obj.creator = request.user
   new_obj.reply_to = form.reply_to
   new_obj.save()

In fact since it’s a foreign key, the new_obj = form.save(commit=False) may have already set .reply_to for you? The Django Model Forms docs may help.
