if need rest of code this github repo
thanks in advance... thank :)
you have forget add post foreignkey field save in views. because did not defined null=true in post foreignkey field in comment model. need assign post model instance when saving comment model instance
def form_valid(self,form,*args,**kwargs): self.object = form.save(commit = false) self.object.aurthor = self.request.user self.object.post = # assign post model instance self.object.save() return super().form_valid(form)
