How to add comma separated values in Django Admin
I have these two models, Category, and Subcategory. They look like this: class Category(models.Model): name = models.CharField(max_length=100) class Subcategory(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) name = models.CharField(max_length=100) So far, this all works great! I'm creating all the starter categories and subcategories for my projects and only have about 15 categories, but each category may wind up having tens of subcategories under them... What I need is a way to be able to copy and paste a ton of subcategory values into the admin form via a comma separated list, and create multiple new objects all at once, all with the same category as their foreign key. This will save me hundreds of clicks. How can this be accomplished? -

How can I implement update and delete in django view?
I am creating a movie review website. In it, I want to be able to allow a User to make one comment on one movie and then Update or Delete that comment. But I am only able to implement POST right now. How do I change the view, html or model? Questions to ask How do I go from here to keep my comments visible so that if one user comments on one movie, I can't comment on it? How can I keep the comments posted by a user at the top of the comment list so that they can be updated and deleted? An example of what we would like to implement is Rotten Tomatoes. class Comment_movie(models.Model): comment = models.TextField(max_length=1000) stars = models.FloatField( blank=False, null=False, default=0, validators=[MinValueValidator(0.0), MaxValueValidator(10.0)] ) user = models.ForeignKey(CustomUser, on_delete=models.CASCADE) movie = models.ForeignKey(Movie, on_delete=models.CASCADE) created_at = models.DateTimeField(default=datetime.now) updated_at = models.DateTimeField(auto_now=True) class Meta: unique_together = ('user', 'movie') indexes = [ models.Index(fields=['user', 'movie']), ] def view_movie_detail(request, movie_id): if not(Movie.objects.filter(id=movie_id)): Movie(id = movie_id).save() movie = Movie.objects.get(id=movie_id) if request.method == "POST": form = Comment_movie_CreateForm(request.POST) if form.is_valid(): Comment_movie( comment = form.cleaned_data['comment'], user = request.user, stars = form.cleaned_data['stars'], movie = movie ).save() return redirect('view_movie_detail', movie_id=movie_id) else: form = Comment_movie_CreateForm() data = requests.get(f"https://api.themoviedb.org/3/movie/{movie_id}?api_key={TMDB_API_KEY}&language=en-US") … -
Django & AJAX to show DB objects upon user's input submission
I'm pretty new in the Web development world, have been using Django so far. I've been trying to figure out how to render data back to page after clicking on a submit button, so I see I'll need to use AJAX for that purpose. I've created a very simple app just to understand the basics of AJAX. However, googling, I couldn't really find a basic straight-forward implementation so I kinda got lost... What I'm trying to achieve: I have a model called Country: class Country(models.Model): name = models.CharField(primary_key=True, max_length=35) continent = models.CharField(max_length=10) capital = models.CharField(max_length=35) currency = models.CharField(max_length=10) And a super simple main page that asks the user to insert some country name. The idea is to bring to the page all the info from the DB. So it would look like this: main page snapshot Main page HTML body: <body> <h2><em>Please type a country name:</em></h2><br><br> <div class="container"> <form id="get_info" method="post"> {{ form }} {% csrf_token %} <input id="submit_button" type="submit" name="submit" value="Get info"> </form> </div> </body> views.py: from django.shortcuts import render from country_trivia import forms def main_page(request): get_info_form = forms.GetInfo() return render(request, 'country_trivia/index.html', {'form': get_info_form}) forms.py: from django import forms class GetInfo(forms.Form): country_name = forms.CharField(label="") I've seen some examples using … -

django allauth login callback going to server behind firewall
My django instance is behind a firewall and there is a front facing proxy that exposes it. Whenever a login request (to google) comes from a user using the proxy website, the callback uri is to the server behind the firewall, and since that server isn't exposed, the login fails. This happens regardless of what servers I have enabled in the google oauth portal. -
Testing redirects to parameterized URLs when creating object
I have a view for creating blog posts which redirects the user to a form to fill the blog post content like this: from django.views import View from app.models import BlogPost class CreateBlogPost(View): def post(): new_post = BlogPost.objects.create() return redirect(reverse('post_edit'), args=[new_post.id]) class EditBlogPost(View): ...

DRF - Prevent users from referencing objects that do not belong to them
I have two models like so with a parent child relation: models.py class Bank(...): user = models.ForeignKey('User', ...) class Account(...) bank = models.ForeignKey('Bank', ...) user = models.ForeignKey('User', ...) I am using DRF and want to provide API access to these models. I want to ensure that Users can only access their own data. On the viewsets I can retrict the querysets to just the objects the user "owns" like so: views.py class BankViewSet(...): def get_queryset(self): return self.queryset.filter( user = request.user ) And I can do the same for Accounts. However, how can I stop a user from creating an Account via POST request with a Bank that they do not own? I want to ensure that users can only create Accounts that belong to a Bank that they own. How can I enforce/check that the Bank in the Account POST request contains the same user as the requestor? -
Updating parent form with a select2 field when closing another modal form django
I am trying to add this functionality to my django app. I have a select2 field as a ForeignKey data type field in my main form. Now, I also got an "add" button right next to it that when clicked, opens a modal with another form. That form creates another instance for the select2 to look for, another entry, so that's good and settled. But, I want it to, when submitting the form in the modal, instead of the main form page being refreshed and having to refill all other fields again, it automatically selects the instance it has just created on the select2 field. I am fairly new to the front-end aspect of it all so it would be great to have some guidance. -
