how can i create a cycle of comments and replies? - django

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

Django - Filtering Post Form option by currently logged-in User's Vehicle

I'm a django newbie and i'm making a form where a User can make a Post and pick one of his Vehicles for the Post. The Vehicle and the Post models are created like so:
*blog/models.py*
class Post(models.Model):
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE, null=True)
def get_absolute_url(self):
return reverse('post-detail', kwargs ={'pk': self.pk} )
*vehicles/models.py*
class Vehicle(models.Model)*:
TESLA = 'TESLA'
MAZDA = 'MAZDA'
VOLVO = 'VOLVO'
VEHICLE_CHOICES = (
(TESLA, "Tesla"),
(MAZDA, "Mazda"),
(VOLVO, "Volvo"),
)
owner = models.ForeignKey(User, on_delete=models.CASCADE)
model = models.CharField(max_length=9,
choices=VEHICLE_CHOICES,
default=TESLA)
def __str__(self):
return self.model
My blog views:
*blog/views.py*
class PostCreateView(LoginRequiredMixin, CreateView):
model = Post
fields = [ 'vehicle']
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
I would like to filter the vehicles so that only the current logged in User's vehicles
show up in the form, i've tried a variety of different solutions but I seem to be going around in circles, if you could help me out that would be awesome. Thanks!
Since you are using createview, you can create a form in forms.py. First you have to send the logged in user to the form, then in the form, pop the user from kwargs and use it to filter the vehicles.
views.py
class PostCreateView(LoginRequiredMixin, CreateView):
model = Post
form_class = PostForm
def get_form_kwargs(self):
kwargs = super().get_form_kwargs()
kwargs['user'] = self.request.user
return kwargs
def form_valid(self, form):
form.instance.author = self.request.user
return super().form_valid(form)
class PostForm(forms.ModelForm):
class Meta:
model = Post
fields = ['vehicle']
def __init__(self, *args, **kwargs):
user = kwargs.pop('user', None)
super().__init__(*args, **kwargs)
self.fields['vehicle'].queryset = Vehicle.objects.filter(owner=user)

This is my view to create a new course!.

form.save()
if forms.is_valid():
forms.save()
return redirect('courses:manage_course_list')
return self.render_to_response({'course': self.course,

Here is my model, am using formset to create course and also

updated = models.DateTimeField(auto_now=True)
students = models.ManyToManyField(settings.AUTH_USER_MODEL,related_name='courses_joined',blank=True)
class Meta:
ordering = ['-created']
def __str__(self):
return self.title
Here is my formset
class CourseForm(forms.ModelForm):
class Meta:
model = Course
fields = ['pic']
ModuleFormSet = inlineformset_factory(Course,
Module,
fields=['title','description',],
extra=2,
can_delete=True)
RequirementFormset = inlineformset_factory(Course,
Requirement,
fields=['requirements'],
extra=4,can_delete=True)
WhatYouWillLearnFormset = inlineformset_factory(Course,
WhatYouWillLearn,
fields=['hightlights'],
extra=4,can_delete=True)
I think the attribute enctype="multipart/form-data" is missing in the form tag in the template file.
<form method="post" enctype="multipart/form-data">
...
...
</form>

User report function

I want to implement a report feature with Django in my blog which users will be able click a link/button under a post and the admin will be notified and he will decide if the post shows up on the homepage or not .
My Post model
class Post(models.Model):
title = models.CharField(max_length=225)
post_image = models.ImageField(null=True, blank=True, upload_to="images/")
author = models.ForeignKey(User, on_delete=models.CASCADE)
body = models.TextField()
post_date = models.DateField(auto_now_add=True)
likes = models.ManyToManyField(User, related_name='blog_posts')
def total_likes(self):
return self.likes.count()
def __str__(self):
return self.title + ' | ' + str(self.author)
def get_absolute_url(self):
return reverse('post-detail', args=(str(self.id)),)
My views.py
def LikeView(request, pk):
post = get_object_or_404(Post, id=request.POST.get('post_id'))
liked = False
if post.likes.filter(id=request.user.id).exists():
post.likes.remove(request.user)
liked = False
else:
post.likes.add(request.user)
liked = True
return HttpResponseRedirect(reverse('post-detail', args=[str(pk)]))
class HomeView(ListView):
model = Post
template_name = 'home.html'
ordering = ['-post_date']
class Suggest(ListView):
queryset = Post.objects.annotate(like_count=Count('likes')).order_by('like_count')
template_name = 'home.html'
context_object_name = 'post_list' # Providing a useful context_object_name is always a good idea
class PostDetail(DetailView):
model = Post
template_name = 'post_detail.html'
def get_context_data(self, *args, **kwargs):
context = super(PostDetail, self).get_context_data()
current_post = get_object_or_404(Post, id=self.kwargs['pk'])
total_likes = current_post.total_likes()
liked = False
if current_post.likes.filter(id=self.request.user.id).exists():
liked = True
context['total_likes'] = total_likes
context['liked'] = liked
return context
class AddPost(CreateView):
model = Post
form_class = PostForm
template_name = 'add_post.html'
# fields = '__all__'
success_url = reverse_lazy('home')
Thanks in advance!

You should probably at least add another attribute to your Post model that can determine whether or not a particular post should even display on the homepage.
From there, I think you need to decide how admins will actually review these posts/set them to be visible on the homepage. It could be as simple as sending them an email and having them log into the django admin to find the post in question and set this new homepage display attribute as needed.
The email could even include a URL to the post in question directly!
For more information on sending emails from django, check this out:

How to specify a list of values ​in a form in which CheckboxSelectMultiple is used?

I have a problem with the form in django. It uses the CheckboxSelectMultiple widget, but I need to set a list of possible choices only for posts created by the currently logged in user.
Any idea?
form:
class CycleForm(BSModalForm):
class Meta:
model = Cycle
fields = ['title', 'description', 'posts']
widgets = {
'posts': forms.CheckboxSelectMultiple(),
}
models
class Cycle(models.Model):
title = models.CharField(max_length=200, unique=True)
description = models.TextField(max_length=500, default="Brak opisu")
date_created = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
posts = models.ManyToManyField(Post)
def __str__(self):
return self.title
class Post(models.Model):
title = models.CharField(max_length=50, unique=True)
content = MDTextField()
date_posted = models.DateTimeField(default=timezone.now)
author = models.ForeignKey(User, on_delete=models.CASCADE)
numbers_of_entries = models.IntegerField(default=0)
views
class CycleCreateView(BSModalCreateView, LoginRequiredMixin):
template_name = 'blog/cycle_form.html'
form_class = CycleForm
def form_valid(self, form, **kwargs):
form.instance.author = self.request.user
return super().form_valid(form)
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
class CycleUpdateView(BSModalUpdateView):
model = Cycle
template_name = 'blog/cycle_update.html'
form_class = CycleForm
success_message = 'Success: Cycle was updated.'
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
We can slightly alter the CycleForm form and add a user parameter. If that parameter is set, we filter the queryset of the posts field by only using Posts
class CycleForm(BSModalForm):
def __init__(self, *args, user=None, **kwargs):
super().__init__(*args, **kwargs)
if user is not None:
self.fields['posts'].queryset = Post.objects.filter(author=user)
class Meta:
model = Cycle
fields = ['title', 'description', 'posts']
widgets = {
'posts': forms.CheckboxSelectMultiple(),
}
Now we only need to pass the user to the form, we can override the get_form_kwargs method [Django-doc]:
class CycleCreateView(LoginRequiredMixin, BSModalCreateView):
template_name = 'blog/cycle_form.html'
form_class = CycleForm
def get_form_kwargs(self):
kwargs = super().get_form_kwargs()
kwargs.update(user=self.request.user)
return kwargs
def form_valid(self, form, **kwargs):
form.instance.author = self.request.user
return super().form_valid(form)
def get_success_url(self):
reverse_user = self.request.user
return reverse('profile', kwargs={'username': reverse_user})
You should do the same with the UpdateView. Note that your LoginRequiredMixin likely should be put first in the base classes.

django class view Overlapping

I am not good at English.
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.
like this
enter image description here
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.
