Django CheckConstraint not enforcing check on model field
I am using Django 3.2. Backend database used for testing: sqlite3 I have a model Foo: class Foo(models.Model): # some fields ... some_count = models.IntegerField() class Meta: models.constraints = [ models.CheckConstraint( check = ~models.Q(some_count=0), name = 'check_some_count', ), ] I also have a unit test like this: def test_Foo_some_count_field_zero_value(self): # Wrap up the db error in a transaction, so it doesn't get percolated up the stack with transaction.atomic(): with self.assertRaises(IntegrityError) as context: baker.make(Foo, some_count=0) When my unit tests are run, it fails at the test above, with the error message: baker.make(Foo, some_count=0) AssertionError: IntegrityError not raised I then changed the CheckConstraint attribute above to: class Meta: models.constraints = [ models.CheckConstraint( check = models.Q(some_count__lt=0) | models.Q(some_count__gt=0), name = 'check_some_count', ), ] The test still failed, with the same error message. I then tried this to check if constraints were being enforced at all: def test_Foo_some_count_field_zero_value(self): foo = baker.make(Foo, some_count=0) self.assertEqual(foo.some_count, 0) To my utter dismay, the test passed - clearly showing that the constraint check was being ignored. I've done a quick lookup online to see if this is a known issue with sqlite3, but I haven't picked up anything on my radar yet - so why is the constraint check … -
Django: Setting IntegerField after form submit
How do i increase the "availability" IntergerField after the form is submitted? Each new product_type is created in the admin panel since i'll only ever need a few of them.

How to assign function to button in Django
I am designing a website based on django. I want to update the user information and delete the user if wanted in the same page. I created updating and it works properly. But when I address the delete user function to same html file , the button that I want it to delete user also updates just like the other button. I need both buttons to work for their own purposes. I thought that without changing anything assigning delete function to button might help thats why I wrote the title like that. Thank you! <div class="login--wrapper"> <form method="POST" class="form"> {% csrf_token %} <div class="center"> <h1>Kullanıcı Ayarları</h1> {% csrf_token %} {% for field in form %} <div class="mb-3"> <label for="exampleInputPassword1" class="from-label">{{field.label}}</label> {{field}} </div> {% endfor %} <button type="submit" class="btn btn-primary">Update Info</button> <button type="submit" class="btn btn-primary">Delete User </button> </div> def DeleteUser(request,pk): user=DataEbotUser.objects.get(id=pk) if request.method=='POST': user.delete() context={'user':user} return render(request,'home/DeleteUser.html',context) def users(request,pk): user=DataEbotUser.objects.get(id=pk) form=EditUserForm(instance=user) if request.method=='POST': form=EditUserForm(request.POST, instance=user) if form.is_valid(): form.save() context={'form':form , 'users':users} return render(request,'home/UsersPage.html',context) -

Django class based view: saved value not loading correctly in a select field
I have a Django 3.2 application running in a production environment, with around 10 simulatenous users.

The model for which the value doesn't load correctly has ~ 130k objects. Sometimes it loads with a void value, sometimes a completely wrong value. Thanks in advance for any hints! best alan -

How to make easy to share offline django projects
I have completed a Django project. It runs well on the development server on my machine. However, it can't be shared and run on other devices easily. How can I package it so that it can easily be shared and run on local server, offline on individual machines? What I do: I use xampp to serve it from Apache then manually copy the necessary files. However this has too many setting up steps, copy paste files and not user friendly at all. Is there a better way? -

How to add fields from other (non-page) models in Wagtail Page admin?
I am looking for a way to include other model's fields in the Page editor of Wagtail. The scenario is a digital marketplace, which we want to deploy for multiple clients. Each client has their own specifications for the marketplace participants and therefore needs different fields in addition to the basic fields (title, address etc.) that we define beforehand. I am looking for a solution for the marketplace admin (which won't be us) to be able to add these extra fields, e.g. via Wagtail snippets. They could create a new Custom Field Snippet and define some options for it. The page admin for marketplace participants then needs to display these extra fields in its form (either in a custom tab or just below all the basic fields in the content panel). Is there a way for me to achieve this? I have managed to get the custom fields into the page form but without any kind of Wagtail styling. I am aware of the similar question here but unfortunately the answers there did not help and the scenario is slightly different here. In the question linked the extra field is in Python code in the model definition, something we want … -
What is the best way to create the following model in Django Rest Framework
I am currently in the process of creating a new model. The current model looks like this, DIET_OPTIONS = ( ('vegan', 'Vegan'), ('vegetarian', 'Vegetarian'), ('meat', 'Meat') ) class Madklub(models.Model): owner = models.ForeignKey(MyUser, related_name="owner", on_delete=models.CASCADE) dish = models.CharField(max_length=100) date = models.DateField() guests = models.PositiveIntegerField() active = models.BooleanField(default=True) participants = models.ManyToManyField(MyUser, related_name="participants") diet = ArrayField( models.CharField(choices=DIET_OPTIONS, max_length=10, default="vegetarian") ) Now the model should be quite simple, the most important fields are the two user relationships and the diet field. The idea is that one Madklub has an owner (a owner can have multiple Madklub). Each Madklub has a list of participants, whenever a Madklub is created it should start out with having only one participant, the owner itself. Now this is the first question, how would I go about doing that automatically, should I simply handle that in the view? Side note, the guests field is a field keeping track of how many non-user guests are invited/participates in the Madklub. Would there be a way to bind this to a user, somehow? Now another question is, as can be seen I currently have the diet field as an ArrayField this of course only works with a Postgres database. As I see it, … -
