Import "project4.app4.models" could not be resolved
I made two projects in django, project4 and project5 and then made two apps app4 and app5 respectively. Now I want to import models of project4 in project5.

Can we update a value after it has been referenced as a foreign key in django?

Digital ocean droplet is only showing the default nginx page when connected with a namecheap domain
I'm using a Django Digital Ocean droplet to run a website where I recently tried connecting the IP address of the droplet to a namecheap domain name, but when I connected them it only showed this on the domain: Welcome to nginx!

No indentations for the options in the select box in an inlined table (Django MPTT)
I created many-to-many relationship with the tables "Category", "Product" and "CategoryProduct" which is the middle table between "Category" and "Product": "models.py": from django.db import models from mptt.models import MPTTModel, TreeForeignKey class Category(MPTTModel): name = models.CharField(max_length=50, unique=True) parent = TreeForeignKey( "self", on_delete=models.CASCADE, null=True, blank=True, related_name="children" ) class MPTTMeta: order_insertion_by = ["name"] def __str__(self): return self.name class Product(models.Model): name = models.CharField(max_length=100) def __str__(self): return self.name class CategoryProduct(models.Model): category = models.ForeignKey(Category, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) class Meta: unique_together = [['category', 'product']] Then, I registered "Category" and "Product" inlined "CategoryProduct" to: "admin.py": from django.contrib import admin from mptt.admin import MPTTModelAdmin from .models import Category, Product, CategoryProduct admin.site.register(Category, MPTTModelAdmin) class CategoryProductInline(admin.TabularInline): model = CategoryProduct @admin.register(Product) class ProductAdmin(admin.ModelAdmin): inlines = [CategoryProductInline] Then, I added some categories and as you can see, the options in the select box of "Parent" have indentations: But when I tried to add a product, as you can see, the options in the select box of "Category" don't have indentations: Is it possible to give indentations to the options in the select box of "Category"?

Django : Create a Form for a dropdown list depending of ID User and Models
I am Newbee in Django. I want to create a Form for a dropdown list. The Dropdown list should show different choices depending on User and the models. I did something directly on the view.py that displays the choices without using a Form from Django and it does not store it. So it is not ideal for what I want to do after the POST. Here are my Models.py class TblAadJntGroup(models.Model): id = models.AutoField(db_column='ID', primary_key=True) # Field name made lowercase. id_aadgroup = models.IntegerField(db_column='ID_AADGroup', blank=True, null=True) # Field name made lowercase. id_aaduser = models.IntegerField(db_column='ID_AADUser', blank=True, null=True) # Field name made lowercase. createdon = models.DateTimeField(db_column='CreatedOn', blank=True, null=True) # Field name made lowercase. createdby = models.CharField(db_column='CreatedBy', max_length=255, blank=True, null=True) # Field name made lowercase. class Meta: managed = False db_table = 'tbl_AAD_jnt_Group' class TblAadGroups(models.Model): id = models.AutoField(db_column='ID', primary_key=True) # Field name made lowercase. idcustomer = models.IntegerField(db_column='IDCustomer', blank=True, null=True) # Field name made lowercase. displayname = models.CharField(db_column='DisplayName', max_length=255, blank=True, null=True) # Field name made lowercase. timestampm = models.DateTimeField(db_column='TimeStampm', blank=True, null=True) # Field name made lowercase. username = models.CharField(max_length=255, blank=True, null=True) class Meta: managed = False db_table = 'tbl_AAD_Groups' So to get the data that I want to display in the dropdown.

Django migrations circular dependency what is the best practice?
I would like to know the best practice to handle CircularDependency when migrating apps. Our CRM has two Apps with several model fields depending on each other. We need to reconstruct the database everyday and this lead us to regenerate and apply migrations everyday. In our code the foreign keys are referenced with : model_name = models.ForeignKey('app.model', ...) So no issues at runtime. But at night, when we regenerate and apply the migrations, we made a migrate script that basically swaps the foreign keys as IntegerField to prevent CircularDependencyError and reswaps them after the depencies are solved. Is there a better way to do this ? -
How to get model objects with AJAX?
I have a Customer model in my Django application. New users are constantly being added to this model in the background and I want to list these customers dynamically with AJAX.

Django setUpTestData does not deepcopy related files
I want to use django setUpTestData to prepare some heavy data shared between multiples unit tests. Instances of my Model are created with some file fields. However, from one test to another, file contents are not renewed, it has side effects between my tests here is a minimalist example : models.py from django.db import models class MyModel(models.Model): my_file = models.FileField(upload_to="tests/") test.py from django.core.files.base import ContentFile from django.test import TestCase from core.models import MyModel class Test(TestCase): @classmethod def setUpTestData(cls): cls.instance = MyModel() cls.instance.my_file.save("file.txt", ContentFile("Hello from setUpTestData")) def test_a(self): with open(self.instance.my_file.path, "r") as fp: self.assertEqual(fp.read(), "Hello from setUpTestData") self.instance.my_file.save("file.txt", ContentFile("Modified data")) def test_b(self): with open(self.instance.my_file.path, "r") as fp: self.assertEqual(fp.read(), "Hello from setUpTestData") self.instance.my_file.save("file.txt", ContentFile("Modified data")) Running any of the two test alone works, however running one after the other one fails: AssertionError: 'Modified datatUpTestData' != 'Hello from setUpTestData' - Modified datatUpTestData + Hello from setUpTestData How to ensure that file are correctly reset? Am I concerned by theses lines from the documentation ? Objects assigned to class attributes in setUpTestData() must support creating deep copies with copy.deepcopy() I feel like fileField should be handled by default by Django but it doesn't work, what should I do?

Why in unit test object's field doesn't change in Django
I don't understand why my test doesn't work. I have a page with product. There is a form with button 'Buy product'. After pushing this button, if a client have enough money, the item will bought and the ammount of money in the account will change. But in my test the ammount of money will be the same after buying a product, although the object(purchased item) will be created.

define a Generic, non serialising field in django rest serializers
This is just a layout of my serializer class SerializerA(serializers.ModelSerializer): field_a = serializers.SerializerMethodField() field_b = serializers.SerializerMethodField() field_c = serializers.SerializerMethodField() field_d = serializers.SerializerMethodField() class Meta: model = TestModel fields = ("field_a", "field_b", "field_c", "field_d", "name", "designation") def get_field_a(self, obj): temp = TempUserModel.objects.get(pk=obj.uuid) field_a = "some ORM query related to temp and TestModel model" return field_a def get_field_b(self, obj): temp = TempUserModel.objects.get(pk=obj.uuid) field_b = "some ORM query related to temp and TestModel model" return field_b def get_field_c(self, obj): temp = TempUserModel.objects.get(pk=obj.uuid) field_c = "some ORM query related to temp and TestModel model" return field_c def get_field_d(self, obj): field_d = "some ORM query related to TestModel model" return field_d Here temp = TempuserModel.objects.get(pk=obj.uuid) is same in 3 out of 4 of the class methods.

Django rest framework: Mixed content
I am quite new in Django rest framework. I have a project which contain Django restframework API inside a Django site project(with simple frontend code) and it works fine in my local environment. However in the production domain(HTTPS) it shows as below: Mixed Content: The page at 'https://<my production domain>/audience/labeling_jobs/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://<my production domain>/audience/labeling_jobs/api/jobs/?page=2'. This request has been blocked; the content must be served over HTTPS. I have setup the configuration about SSL/HTTPS according to Django document SSL/HTTPS beforehand but it still got this error. USE_X_FORWARDED_HOST = True SECURE_PROXY_SSL_HEADER = ('HTTP_X_FORWARDED_PROTO', 'https') SESSION_COOKIE_SECURE = True CSRF_COOKIE_SECURE = True SECURE_CONTENT_TYPE_NOSNIFF = True SECURE_HSTS_INCLUDE_SUBDOMAINS = True SECURE_HSTS_PRELOAD = True SECURE_SSL_REDIRECT = True It seems that the Django rest cannot get the correct HTTPS, but it works fine with other django paths, they can be showed on the production page. Is there anything I have missed? -
How to call an API constantly with a function?
I have a customer management system. I am using an API to get all of the customers. It works perfectly. I am using an ID, if there is no customer who has this ID, then it creates a new customer. Here is my code for that: def handle_get_customers(company): customer_service = requests.get(settings.API_ADDRESS + "customer/get/all", headers={'Authorization': "Bearer " + token_key}).json() service_customers = [] for customer in customer_service["data"]: service_customers.append(customer) for person in service_customers: new_customer, obj = Customer.objects.get_or_create(api_id=person["id"]) new_customer.customer_name = person["name"] country, d = Country.objects.get_or_create(country_name=person["countryName"]) new_customer.country = country new_customer.address = person["fullAddress"] new_customer.phone_number = person["phoneNumber"] new_customer.email_address = person["email"] new_customer.currency_choice = person["currency"] new_customer.api_id = person["id"] new_customer.company = company new_customer.save() return service_customers And I am listing all customers on a page. It has a basic listing function like; def customer_list(request): current_user = request.user handle_get_customers(current_user.company) customer_list = Customer.objects.filter(company=current_user.company) context = { 'customer_list': customer_list, } return render(request, 'customer_list.html', context) I want to get all new companies without refreshing the page. I don't know if I can use Ajax for that but I guess the handle_get_customers function should work constantly but I cannot figure out how can I do it? -

New clients cannot connect to Django site when site are being used by other clients
We have a Django based web application that is being deployed with Apache and mod_wsgi. The users logs in and can start some CPU-bound processes that can take up to 1-2 minutes. Our problem is, when these CPU-bound processes are being run, the new clients cannot even load the site. Even if they can load it and enter their credentials and press log in button, the site is not opening before the ongoing processes are completed. DEBUG option is False in deployment environment. We are not using django.contrib.staticfiles serve() function to serve our static files. How can I find the reason behind this delay? I suspect that this happens because static content are not being served with a different server? How can I make sure that this is the problem? If that is the problem, can serving the static files with a different virtual host solve the issue? Due to company policy, I cannot share the code directly here. However please let me know if there is any other information I need to elaborate. Thanks for your time and attention in advance. -
