I wonder how can I make a cycle of comments and replies :
I wanted to make a replyable comment but replies also need to be replyable to make a better communication but I'm just a student and don't have much experience
here is my models :
class Comment(models.Model):
#comments model
post = models.ForeignKey(Post, on_delete=models.CASCADE)
text = models.CharField(max_length=300)
user = models.ForeignKey(get_user_model(),on_delete=models.CASCADE)
date = models.DateTimeField(auto_now_add=True)
class Meta():
verbose_name_plural = 'Comments'
ordering = ['date']
def __str__(self):
return self.test[:50]
class Reply(models.Model):
#replying to comments
comment = models.ForeignKey(Comment,on_delete=models.CASCADE)
text = models.CharField(max_length=300)
user = models.ForeignKey(get_user_model(),on_delete=models.CASCADE)
date = models.DateTimeField(auto_now_add=True)
class Meta():
verbose_name_plural = 'Replies'
ordering = ['date']
def __str__(self):
return self.text[:50]
problem is that if i use this models i have to make a new model for every reply and it's not in cycle.
also I tried to check if replyable comment works or not and i got a problem with view:
I couldn't add both forms(comment, reply) in the same get_context_data()
class PostDetailView(FormView, DetailView):
#detail page of items
template_name = 'pages/post_detail.html'
model = Post
form_class = CommentForm, ReplyForm
def get_context_data(self, **kwargs):
context = super(PostDetailView, self).get_context_data(**kwargs)
context['form'] = self.get_form()
return context
def post(self,request, *args, **kwargs):
form = CommentForm(request.POST)
if form.is_valid():
form_instance = form.save(commit=False)
form_instance.user = self.request.user
form_instance.post = self.get_object()
form_instance.save()
return HttpResponseRedirect(self.get_success_url())
else:
super().is_invalid(form)
def get_success_url(self):
return reverse('pages:post_detail',args=(self.kwargs['pk'],))
how can i fix views and make comments and replies both replyable

Hello asd you can add flags like this in your Profile Model like this
class Profile(models.Model):
user = models.ForeignKey(User,on_delete=models.PROTECT)
is_moderator = models.BooleanField(default=False)
is_editor = models.BooleanField(default=False)#you can add many more as you want
and you can validate user in template or in views like this
in views.py
def check_user(request):
moderator_profile = Profile(user_id=request.user.id,is_moderator=True)
editor_profile = Profile(user_id=request.user.id,is_editor=True)
if user_profile:
return redirect('url_for_moderator')
elif editor_profile:
return redirect('url_for_editor')
OR
you can pass data to the template and give certain functionality for certain user
like this
in your views.py
def get_post(request):
user_profile = Profile.objects.filter(user=request.user.id)
return render(request,"post.html",{"user_profile":user_profile})
and inside post.html
{% if user_profile.is_editor or user_profile.is_moderator %}
<button>Edit</button>
{% endif %}
if you don't like this way you can do it in better way check this post

Trying to get post id in Detailview in views.py .I am trying to add like button on blog Detail page.

Error in terminal
#error
post = get_object_or_404(Post, id=self.kwargs['id'])
KeyError: 'id'
self.kwargs is different in get_context_data kwargs, and kwargs depend of your url
replace:
post = get_object_or_404(Post, id=self.kwargs['id'])
by :
post = self.get_object()
you are in DetailView, so you have methods get_object, for getting yout post object with verify if object exsits
I created an update screen for django. However, although it redirects to successURL, the data has not been updated. I don't know why.
I need your help.

Please understand me.
I'm creating a blog in Django.
I am making it into class view, but I want to see a reple list and form in the post details view.

POST detailview has already been implemented and I don't know how to add comments.
Should I be function view?
Give me some advice.

It's my first time writing, so I don't know how to Indent. Sorry
And if my code is not effective, tell me how to fix it.
thank you!
It might be easier to write the view from scratch as a function, but you can also override the existing post method to return additional data.
