Django Rest Framework : Why Complex nested serializer tries to create nested fields in database when calling .is_valid()?
Context I have a project in which there are three entities : Account, Community and JoinRequest. A JoinRequest binds an Account (user) with a Community. And there should not be more than one JoinRequest for any couple (Account, Community). Problem I coded the respective models, serializers and unittest, which you can see below. But when I run my test, I get the following error... I don't understand, it seems the .is_valid() method of the JoinRequestSerializer tries to recreate an Account and a Community, whose data were previously passed as arguments at construction of the instance... Any idea why this error appears? join_request_serializer.errors {'user': {'email': [ErrorDetail(string='account with this email already exists.', code='unique')], 'username': [ErrorDetail(string='account with this username already exists.', code='unique')], 'password': [ErrorDetail(string='This field is required.', code='required')]}, 'community': {'name': [ErrorDetail(string='community with this name already exists.', code='unique')]}} Account class MyAccountManager(BaseUserManager): def create_user(self, email, username, password=None): if not email: raise ValueError('Users must have an email address') if not username: raise ValueError('Users must have an username') user = self.model( email=self.normalize_email(email), username=username, ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, username, password): # This method must be overridden to use MyAccountManager class user = self.create_user( email=self.normalize_email(email), username=username, password=password, ) user.is_admin = True user.is_staff = True user.is_superuser … -

django - ValueError: Dependency on app with no migrations
I'm deploying my Django project to a VPS using Dokku. My project uses a CustomUser model, and there are two apps in the project: accounts which has the CustomUser and gradebook. During deployment the process runs makemigrations and migrate. After deployment when I run python manage.py showmigrations I get the following: account [X] 0001_initial [X] 0002_email_max_length accounts (no migrations) admin [X] 0001_initial [X] 0002_logentry_remove_auto_add [X] 0003_logentry_add_action_flag_choices auth [X] 0001_initial [X] 0002_alter_permission_name_max_length [X] 0003_alter_user_email_max_length [X] 0004_alter_user_username_opts [X] 0005_alter_user_last_login_null [X] 0006_require_contenttypes_0002 [X] 0007_alter_validators_add_error_messages [X] 0008_alter_user_username_max_length [X] 0009_alter_user_last_name_max_length [X] 0010_alter_group_name_max_length [X] 0011_update_proxy_permissions [X] 0012_alter_user_first_name_max_length contenttypes [X] 0001_initial [X] 0002_remove_content_type_name gradebook (no migrations) sessions [X] 0001_initial sites [X] 0001_initial [X] 0002_alter_domain_unique Where account is from django-allauth.

What will be the best approach for setting up multiple subdomains in a single django project using mysql?
I am about to build a web-app and use it as a product for multiple organizations. Let's say my domain name is example.com And I have 2 customers, org1 (Organization 1) and org2 (Organization 2) So, my sub domains would be org1.example.com and org2.example.com Now, I have gone through the Django tenant approach which uses PostgreSQL. But I am looking for something in MySQL. But my question is that is it possible for me to use MySQL and use separate databases, to maintain risk free and also data privacy for orgs, and also use Django tenant or is there some different approach to solve this subdomain issue? Do note, I'll be using my platform as a product so the subdomains would be given to each client who would be given credentials to access the platform (Kinda like an inventory system). Any links or videos is highly appreciated. -
Display objects related to requested object and children in Materialized Path trees
categories/models.py from django.db import models from treebeard.mp_tree import MP_Node class Category(MP_Node): title = models.CharField(max_length=50) slug = models.SlugField(unique=True) node_order_by = ['title'] class Meta: verbose_name = 'category' verbose_name_plural = 'categories' def __str__(self): return 'Category: {}'.format(self.title) categories/views.py from django.views.generic import DetailView from .models import Category class CategoryDetailView(DetailView): model = Category context_object_name = 'category' template_name = 'categories/category_detail.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["products_in_category"] = self.object.products.filter(active=True) return context category_detail.html ..... {% for p in products_in_category %} <h2><a href="{{ p.get_absolute_url }}">{{ p.title }}</a></h2> ..... The code above works well to display products that belong to a specific category but I would also be able to display the products that belong to its descendants. Example: shoes ├── sneakers │ ├── laced sneakers │ └── non-laced sneakers If I'm on the category page for sneakers I would want to be able to see products related to both Laced Sneakers and Non-laced Sneakers. My thought was that the get_context_data could look something like this def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context["products_in_category"] = self.object.get_descendants().products.filter(active=True) return context But unfortunately, that did not work out. I was thinking about using ListView instead but the category page will have a description describing the category and for that reason, I figure DetailView would … -
Sorting a JSONField by adding an index value?
I am using a JSONField to store a custom form with field labels/values. I am having an issue when rendering the form. Each time the form gets rendered, the order is changed since I am using a dictionary. I was thinking of adding an extra value to my JSONField just to store an integer, in which I can order by. I am wondering if this is a possible solution, or if there was any other "best" way to keep this form in order. I have a simple model, class House(models.Model): form = JSONField(default=dict) Which in my view a json file is loaded into it with a json file as such. { "outside": [ { "fields": [ { "label": "Pool", "value": "" }, { "label": "Shed", "value": "" }, ], "index": 0 } ], "inside": [ { "fields": [ { "label": "Bedrooms", "value": "" }, { "label": "Baths", "value": "" }, ], "index": 1 } ], When the form is rendered in my view, I am using basic logic house = House.objects.get(id=1) form = house.form.items() return render(request, template, context={'form': form} The json loads fine the first time, with all fields with the label outside leading, and then fields with the label … -

DRF: router for ViewSet with a foreign-key lookup_field
Using Django REST Framework 3.12.4, I cannot properly get the URLs for a ViewSet to work if that ViewSet has a foreign-key lookup field. I have the following in models.py: class Domain(models.Model): name = models.CharField(max_length=191, unique=True) class Token(rest_framework.authtoken.models.Token): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) domain_policies = models.ManyToManyField(Domain, through='TokenDomainPolicy') class TokenDomainPolicy(models.Model): token = models.ForeignKey(Token, on_delete=models.CASCADE) domain = models.ForeignKey(Domain, on_delete=models.CASCADE) class Meta: constraints = [models.UniqueConstraint(fields=['token', 'domain'], name='unique_entry')] In views.py, I have: class TokenDomainPolicyViewSet(viewsets.ModelViewSet): lookup_field = 'domain__name' permission_classes = (IsAuthenticated,) serializer_class = serializers.TokenDomainPolicySerializer def get_queryset(self): return models.TokenDomainPolicy.objects.filter(token_id=self.kwargs['id'], token__user=self.request.user) You can see from TokenDomainPolicyViewSet.lookup_field that I would like to be able to query the -detail endpoint by using the related Domain's name field instead of its primary key. (name is unique for a given token.) I thought this can be done with lookup_field = 'domain__name'. However, it doesn't quite work. Here's my urls.py: tokens_router = SimpleRouter() tokens_router.register(r'', views.TokenViewSet, basename='token') tokendomainpolicies_router = SimpleRouter() tokendomainpolicies_router.register(r'', views.TokenDomainPolicyViewSet, basename='token_domain_policies') auth_urls = [ path('tokens/', include(tokens_router.urls)), # for completeness only; problem persists if removed path('tokens/<id>/domain_policies/', include(tokendomainpolicies_router.urls)), ] urlpatterns = [ path('auth/', include(auth_urls)), ] The list endpoint works fine (e.g. /auth/tokens/6f82e9bc-46b8-4719-b99f-2dc0da062a02/domain_policies/); it returns a list of serialized TokenDomainPolicy objects. However, let's say there is a Domain object with name = 'test.net' related … -

Django: Include a html on ajax request
I am using Django as my Webframework togehter with Ajax for async calls. When a button is pressed I want an entire HTML file to be loaded in (like normal includes). This is the AJAX code: $.ajax({ url: "{% url 'project-detail' project_object.id %}", type: 'get', data: { ... }, success: function (response) { $("#div1").html("{% include 'projects/recommendations.html' %}") } }) As you can see I try to wrap {% include 'projects/recommendations.html' %} with ".". This unfortunatley doesnt work. As a work around I thought of reading the file in and output the string. As the to be included file is also relatively large ~150 LOC I try to avoid having it all in one file. Is there a way to neatly load this in? -

Django Bulk Create doesn't respect ignore_conflicts for django.db.utils.IntegrityError
I am trying to do two sequential bulk creates to sync data to django from another data store. The problem is the data store allows duplicates but I don't want to allow that in my django schema. I'm ok losing the duplicates. Duplicates are based on two of the items fields The first bulk create generates a bunch of items, the second creates a through field for those items. If there is a duplicate in the first list of items, the second bulk create fails since it is trying to create a through field for a item that doesn't exist. I would want that second create to fail gracefully like the first since I'm using ignore_conflicts=True but it throws an exception and no other items get created. Even worse, since I'm supplying the primary key the first bulk create returns all of the items, even if they weren't actually created. I'm creating hundreds of these every second, so I have to use bulk create. Anyway to get bulk create to ignore the IntegrityError exception? I'm using postgresql. -

Here is my code: `urlpatterns = [ path('admin/', admin.site.urls), re_path(r'^', include('EmployeeApp.urls')) ]` App.urls: `urlpatterns=[ re_path(r'^department$',views.departmentApi, name='department'), re_path(r'^department/([0-9]+)$',views.departmentApi, name='departmentApi'), re_path(r'^employee$',views.employeeApi, name='employee'), re_path(r'^employee/([0-9]+)$',views.employeeApi, name='employeeApi'), re_path(r'^Employee/SaveFile$', views.SaveFile, name='SaveFile') ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)` The view: @csrf_exempt def departmentApi(request, id=0): if request.method == 'GET': department = Departments.objects.all() departments_serializer = DepartmentSerializer(department, many=True) return JsonResponse(departments_serializer.data, safe=False) elif request.method == 'POST': department_data = JSONParser().parse(request) department_serializer = DepartmentSerializer(data=department_data) if department_serializer.is_valid(): department_serializer.save() return JsonResponse("Added Successfully!!", safe=False) return JsonResponse("Failed ro Add.",safe=False) elif request.method=='PUT': department_data = JSONParser().parse(request) department=Departments.objects.get(DepartmentId=department_data['DepartmentId']) department_serializer=DepartmentSerializer(department,data=department_data) if department_serializer.is_valid(): department_serializer.save() return JsonResponse("Updated Successfully!!", safe=False) return JsonResponse("Failed to Update.", safe=False) elif request.method == 'DELETE': department = Departments.objects.get(DepartmentId=id) department.delete() return JsonResponse("Deleted Successfully!!", safe=False) @csrf_exempt def employeeApi(request,id=0): if request.method=='GET': employees = Employees.objects.all() employees_serializer = EmployeeSerializer(employees, many=True) return JsonResponse(employees_serializer.data, safe=False) elif request.method=='POST': employee_data=JSONParser().parse(request) employee_serializer = EmployeeSerializer(data=employee_data) if employee_serializer.is_valid(): employee_serializer.save() return JsonResponse("Added Successfully!!" , safe=False) return JsonResponse("Failed to Add.",safe=False) elif request.method=='PUT': employee_data = … -
<!DOCTYPE html> missing in Selenium Python page_source
I'm using Selenium for functional testing of a Django application and thought I'd try html5lib as a way of validating the html output. One of the validations is that the page starts with a <!DOCTYPE ...> tag. The unit test checks with response.content.decode() all worked fine, correctly flagging errors, but I found that Selenium driver.page_source output starts with an html tag. I have double-checked that I'm using the correct template by modifying the title and making sure that the change is reflected in the page_source. There is also a missing newline and indentation between the <html> tag and the <title> tag. This is what the first few lines looks like in the Firefox browser. <!DOCTYPE html> <html> <head> <title>NetLog</title> </head> Here's the Python code. self.driver.get(f"{self.live_server_url}/netlog/") print(self.driver.page_source And here's the first few lines of the print when run under the Firefox web driver. <html><head> <title>NetLog</title> </head> The page body looks fine, while the missing newline is also present between </body> and </html>. Is this expected behaviour? I suppose I could just stuff the DOCTYPE tag in front of the string as a workaround but would prefer to have it behave as intended. Chris
