colorpicker and field validation
I am using TabularInlines to gather some information, one of which is a colorfield: class UnitForm(forms.ModelForm): class Meta: model = Unit fields = ["date", "name", "label", "color"] widgets = {"color": TextInput(attrs={'type': 'color'}),} class UnitTabularInline(admin.TabularInline): form = UnitForm model = Unit extra = 0 ##workaround class StockAdmin(admin.ModelAdmin): list_display = [] inlines = [UnitTabularInline] My problem is, without the extra = 0 switch, I always see 3 "empty" fields (which I actually want to see). But I cannot save my form, if I do not fill out all the fields, because the colorpicker has a preselected value. It seems that when input has type="color" there is always a color defined, and there's no way to set that string to empty. Can I somehow skip form validation for fields, that only have color in self.chagned_data or something like this? I would like the other edits to be saved. The model: class Unit(models.Model): name = models.CharField("name", max_length=128, blank=True, null=True) date = models.DateField() stock = models.ForeignKey(Stock, on_delete=models.CASCADE) label = models.CharField("extra label", max_length=32, null=True, blank=True) color = models.CharField(max_length=7, null=True, blank=True) -

What should I do if data is not saved in Django?
I'm new to Django. And I'm faced with the problem of saving data from the form to the database. I was writing code in PyCharm. The main problem is that the data is not saved in the database. There are no errors, no warnings, NOTHING. Everything works except saving. I will be very grateful for your help! Here is the code: views.py: `from django.shortcuts import render, redirect from .models import Articles from .forms import ArticlesForm def news_home(request): news = Articles.objects.order_by('title') return render(request, 'news/news_home.html', {'news': news}) def create(request): error = '' if request.method == 'POST': form = ArticlesForm(request.POST) if form.is_valid(): article = form.save() return redirect('news_home') else: error = 'Unfortunately, the form was not filled out correctly.' form = ArticlesForm() data = { 'form': form, 'error': error } return render(request, 'news/create.html', data)` models.py: `from django.db import models class Articles(models.Model): title = models.CharField('name', max_length=50) anons = models.CharField('anons', max_length=250) full_text = models.TextField('article') date = models.DateTimeField('Date of publication') def __str__(self): return self.title class Meta: verbose_name = 'news' verbose_name_plural = 'news'` forms.py: `from .models import Articles from django.forms import ModelForm, TextInput, DateTimeInput, Textarea class ArticlesForm(ModelForm): class Meta: model = Articles fields = ['title', 'anons', 'full_text', 'date'] widgets = { "title": TextInput(attrs={ 'class': 'form-control', 'placeholder': 'the name … -
How to save the child set instance in the parent object in Django's Many to One (Foreign Key) relationship?
I am working on a social media project where users can follow each other. Here are the models that are relevant to this problem django.contrib.auth.models.User class UsersProfiles(ddm.Model): user = ddm.OneToOneField( dcam.User, on_delete=ddm.CASCADE, related_name="profile", ) followers_count = ddm.IntegerField(default=0) followings_count = ddm.IntegerField(default=0) class UsersFollows(ddm.Model): follower = ddm.ForeignKey( dcam.User, on_delete=ddm.CASCADE, related_name="followers", ) following = ddm.ForeignKey( dcam.User, on_delete=ddm.CASCADE, related_name="followings", ) I am creating data redundancy for scalability by storing the followers and followings counts instead of calculating it by using UsersFollows model. So I am using Django's transaction to add a follower for atomicity. with ddt.atomic(): umuf.UsersFollows.objects.create( follower=user, following=followed_user, ) followed_user.profile.followers_count += 1 user.profile.followings_count += 1 followed_user.profile.save() user.profile.save() But during the testing, the user to its followers and followings set is appearing empty. def test_valid(self): response = self.client.post( c.urls.USERS_1_FOLLOWINGS, {"user": 2}, headers=h.generate_headers(self.login_response), ) h.assertEqualResponses(response, c.responses.SUCCESS) user1 = dcam.User.objects.get(pk=1) user2 = dcam.User.objects.get(pk=2) self.assertEqual(user1.profile.followings_count, 1) self.assertEqual(user2.profile.followers_count, 1) follow = umuf.UsersFollows.objects.filter( follower=user1, following=user2, ) self.assertEqual(len(follow), 1) # Below 2 assertions are failing self.assertIn(user1, user2.followers.all()) self.assertIn(user2, user1.followings.all()) I tried saving both the User instances. I also tried saving the UserFollow instance just in case the create function did not save it automatically. umuf.UsersFollows.objects.create( follower=user, following=followed_user, ).save() user.save() followed_user.save() I don't get what am I missing here. -

Manual Django form not saving no matter what I do to Postgres database
I have a problem with saving a form to the database. Everything I've tried doesn't work and I really don't know what else to do.

How can I get my crispy form to work in Django in the login process?

How to use variable to iterate in django template?
I'm using python and django and I would like to use a variable I entered in a previous input, to iterate over creating multiple other input fields. This is the part in the Django template where I ask the number I would like to use in the iteration: <form method="GET"> <label for="grondstoffen_count" style="font-family: Oswald, sans-serif;">Give how many products were delivered:</label> <input type="number" name="grondstoffen_count" id="grondstoffen_count" min="0" required> <button type="submit" name="submit_count">Bevestig</button> </form> This is the part my views.py where I generate a string of the sequence up to the input number. When I have the string I return it to the Django template: elif 'submit_count' in self.request.GET: grondstoffen_count = int(self.request.GET.get('grondstoffen_count', 0)) volgordelijst = "" for i in range(1, grondstoffen_count + 1): volgordelijst += str(i) print(type(volgordelijst)) # string print(volgordelijst) # when grondstoffen_count is 5 then this gives "12345" return render(self.request, 'Ano_app/BehandelNieuweVoorraad.html', {'volgordelijst': volgordelijst}) In the template I receive the 'volgordelijst' (so I don't think it's a problem with giving the variable from the view to the template because the name is automatically suggested) and I would like to use that variable for the loop. I would like to have as many input fields as the number in the original input but when I … -

Why won't my home page redirect to a detail view (Django)
So the context is I'm following a tutorial on codemy.com. Somewhere before Django 5.0 I lost my "magic", the tutorial was written for 3.8 or 4.X maybe. I am showing a function based view although I have tried the class base view as suggested on the codemy youtube.

Django products not being added to cart immediately
So I am trying to build a Django e-commerce website, where there is a cart modal which pops up when I try to add any product by clicking the add to cart button. While the product is being added correctly in the backend (which I can verify by going to admin panel), the product just doesn't show up immediately on my cart modal, something which is essential for the website to look good.
