Django DRF OneToOneField for muliple user types
I am trying to implement multiple user types in DRF and I'm doing that by having a User Model - which has login related fields and common fields in all the roles and also a choice field denoting type of user. Customer Model - OneToOneField with user model. Seller Model - OneToOneField with user model. I have set up authentication and permissions for User model and now I'm able to log in. I want the logged in user to be able to create his respective profile (based on user_type field of User model). class User(AbstractBaseUser, PermissionsMixin): """ A Generic User inside our system. The fields used are common to all users in letzbargain system. """ .... class Customer(models.Model): """A Class to represent a Customer in System """ user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) Now I am trying to figure out how to allow a user to create a profile respective to his user_type (customer/seller). and the more confusing part is how do I set the user to current logged in user for my CustomerSerializer or SellerSerializer This is the permission class I'm trying to use: class UpdateCustomerProfile(permissions.BasePermission): """Allow users to edit their own profile """ def has_object_permission(self, request, view, obj): """Check … -
Django-CMS NoReverseMatch
I'm trying to use Django-CMS in a existing project. I read the docs (http://docs.django-cms.org/en/latest/how_to/install.html and http://docs.django-cms.org/en/latest/how_to/apphooks.html) and I tried to solve my problem with django-cms: urls used by apphooks don't work with reverse() or {% url %} but none of these helped me. Problem: I can't reverse any url. Wheneve I try to reverse something I get this error: django.urls.exceptions.NoReverseMatch: 'poll' is not a registered namespace here is my cms_apps.py: @apphook_pool.register class PollApp(CMSApp): name = "Umfragen" app_name = "poll" urls = ["apps.poll.urls"] poll/urls.py: app_name = "poll" urlpatterns = [ # Some other paths path('', views.search, name="search"), ] heres what I tried: {% url 'poll:search' %} reverse("poll:search") reverse("de:poll:search") reverse("cms:poll:search") -
DRF does not reverse Django url pattern: NoReverseMatch
There is a complex app (not possible to just paste the code). Going to try to explain. Django There is a urls.py file from the native Django app. The urlpatterns defines and register its urls. The ^foo/ defines a group of related urls and the foonamepsace. urlpatterns = patterns('', ... url(r'^foo/', include('foo.urls', namespace='foonamespace')), ... Now there is a method generate_report which does some logic inside and then uses render_to_string to return the HTML: def generate_report(..): ... return render_to_string('foo/foo_report.html', args) Everything works inside the app, the url get reversed successfully. Django Rest Framework (DRF) Now there is a DRF implementation and one of its resources is supposed to return a report in a binary format. class PDFReportViewSet(APIView): renderer_classes = (BinaryFileRenderer, ) def get(..): ... pdf = generate_report() # <-- fails with NoReverseMatch ... return response Problem The ViewSet calls the generate_report, however one gets an error when trying to parse the HTML: NoReverseMatch: foonamespace' is not a registered namespace Question Any clues why DRF cannot reverse the namespcae/url from the the core of Django app? How to make DRF know about this particular HTML template file? -

How to speed up writing in a database?
I have a function which search for json files in a directory, parse the file and write data in the database. My problem is writing in database, because it take around 30 minutes. Any idea how can I speed up writting in a database? I have few quite big files to parse, but parsing the file is not a problem it take around 3 minutes.

Django: constrain foreign key to only rows with the same id

Is this possible? If it matters, I am using PostgreSQL -
Chaining update and get method in Django for updating fields
I have a Django Model as follows: class IPGroup(models.Model): name = models.CharField(max_length=50, unique=True) junos_space_id = models.CharField(max_length=50) class Jira(models.Model): jira_id = models.CharField(max_length=50, unique=True) ip_groups = models.ForeignKey(IPGroup, null=True, on_delete=models.SET_NULL) Now I have a atomic ORM transaction as follows: try: with transaction.atomic(): IPGroup.objects.filter(id=2).update(junos_space_id=3) Jira.objects.filter(jira_id=2)).update(ip_groups_id=2) except Exception: response = Response(status=status.HTTP_500_INTERNAL_SERVER_ERROR, data={'status': 'Database error encountered'}) This works well when everything is fine.However, when an error occurs as in case of an wrong id, filter just gives an empty queryset and it never hits the exception. I tried re-writing it with a get instead of a filter as follows: try: with transaction.atomic(): IPGroup.objects.get(id=2).update(junos_space_id=3) Jira.objects.get(jira_id=2)).update(ip_groups_id=2) except Exception: response = Response(status=status.HTTP_500_INTERNAL_SERVER_ERROR, data={'status': 'Database error encountered'}) But is gives me the following attribute error: AttributeError: 'IPGroup' object has no attribute 'update' What is the best way to doing this in a clean way ? -
Configure Django/Celery to send tasks to different broker
The system is running a Django server (1.11.5) with Celery (4.0.0) and RabbitMQ as broker. It is necessary to send some tasks to a remote server to be processed there. This new server will have its own RabbitMQ installed to use it as broker. The problem comes when on the server where Django is running we need to select which of the tasks keep running on the local machine and which are sent to the new server. Due to some architecture reasons is not possible to solve this using queues, tasks must be sent to the new broker. Is it possible to create two different Celery apps in Django (each one pointing to a different broker) which their own tasks each one? How can it be done? -
Django Rest Framework override viewset list method optionally?

build When Case query in for loop django
i try build queryset for update data with When Case. It only can build after one for loop. Example i have model Employee: class Employee(models.Model): account_type = models.TextField(blank=True, null=True) i want update it like this, if id = 1 then value = 1, if value = 2 then value = 2 Employee.objects.update( account_type=Case( When(id=1, then=Value("1")), When(id=2, then=Value("2")), ), ) but i want id is dynamic, so i cant build static queryset. I want build Case in one for loop. My ideal like this: final_case = None for one_id in list_id: final_case += Case(When(id=one_id, then=Value(one_id))) I want build final_case and update only like Employee.objects.update(account_type=final_case) Anybody know how to do it ?

How to fix tests after Django 1.10 to 1.11 update
I'm working on a project that uses Django 1.10 and DRF. When I upgrade Django to 1.11, many tests in classes that inherit from DRF's APITestCase fail with the following error: AttributeError: 'HttpResponseBadRequest' object has no attribute 'data' In Django 1.10, however, if I try to access an non-existing attribute of the response, I get: AttributeError: 'Response' object has no attribute 'ariel' DRF's test client extends Django's test client, so I suppose that class changed its interface from 1.10 to 1.11 and is doing some magic and returning an instance of this new HttpResponseBadRequest class, which doesn't have a "data" attribute. However, I didn't find these changes documented anywhere and I didn't find any discussion online proposing a solution for this. Does anybody have any idea what has to be changed and where I can find documentation for the new test client interface? -

Django: Global modification of readonly field appearance
I want to customize the field texture in django’s new “readonly mode”: E.g. foreign keys shall be displayed as links. In general I identified the following options: Implement custom fields for every model – results in code duplication Reimplement django’s display_for_field method Basically I could copy & paste the django.contrib.admin.utils module, insert my changes, override sys.modules['django.contrib.admin.utils'] = myutils but that's ugly because of maintainability in case of Django updates in the future. So I decided to override only the display_for_fields method of django.contrib.admin.utils using the following approach to avoid duplication of Django code: Override display_for_field function in django.contrib.admin.utils in settings.py: from myapp.contrib.admin import utils utils.override_method() In myapp.utils.py: from django.contrib.admin import utils from django.contrib.admin.utils import * def display_for_field_mod(value, field, empty_value_display): if isinstance(field, models.ForeignKey) and value: if field.related_model.__name__.lower() != 'user': link_string = 'admin:myapp_' + field.related_model.__name__.lower() + '_change' link = reverse(link_string, args=(value.id,)) return format_html('<a href="{}">{}</a>', link, value) else: return formats.localize(value) else: return display_for_field(value, field, empty_value_display) def override_method(): utils.display_for_field = display_for_field_mod But the problem is: display_for_field gets imported in django.contrib.admin.helpers using: from django.contrib.admin.utils import ( display_for_field, [...] ) So due to the scope of the imported funtion I cannot override this function from outside. Do I miss some other obvious possibility? Is there a … -
