How to make django work with a table in a different schema in a different database?
I have a django model which work with remote table in a remote database. class CampaignSpSdRequest(models.Model): asins = models.CharField(max_length=200000) skus = models.CharField(max_length=200000, null=True, blank=True) class Meta: managed = False db_table = 'search\".\"CampaignSpSdRequest' The issue is I get the following error: INFO:root:relation "search.CampaignSpSdRequest" does not exist INSERT INTO "search"."CampaignSpSdRequest" For some reason it ads quotas also on CampaignSpSdRequest. It works with other tables, only this one has the problem. Any idea what is going on? Correct insert statement should be like this: INSERT INTO "search".CampaignSpSdRequest -
Django form field for integer list and using it for ModelMultipleChoiceField
I would like to have a form field with TextInput widget (for example CharField) for recieving comma-separated positive integer lists, for example: 0, 1, 2,7, 645, 345, 1000. I want to use it with ModelMultipleChoiceField (so the integer values represent pk). How could I achieve this? From the documentation it is not obvious how to create such field and how to make it work with ModelMultipleChoiceField (how to use the integer list returned from TextInput in ModelMultipleChoiceField to get the objects queryset). -
Django render admin panel with markdown fields
I am having trouble with markdown on my Django application. I am writing an admin panel and want to use the markdown field.

select_related in view is not reducing queries with hybrid property in Django

Change Like button colour when a post is liked
i have this social media application and i want when a user has liked a post the colour is red and if not it is black.

Workaround for lack of ArrayField/JSONField in sqlite?
I'm trying to make tests on a django project run faster by switching to sqlite instead of postgres for test runs, and am running into issues because some models use ArrayField or JSONField, which are postgres specific. Is there any workaround I could use to make this work? For instance something like a 3rd party library that could monkeypatch ArrayField and JSONField and rebuild them on top of CharField? - or some hack of this nature, not good for prod but good enough to speed up tests... I can't be the first one trying to make this work! -
How to redirect to frontend login page in react after account activation via email sent by Djoser in django and drf
I am in the process of implementing Djoser into my current project. On the front end I have a form for registration, onSubmit and onSuccess redirect to a page telling the user to check their email and click the activation link. This link and email are sent by Djoser. The email now prints in the console and it looks like this: <p>Please go to the following page to activate account:</p> <p><a href="http://127.0.0.1:8000/activate/OQ/bnjmpy-22a214344550a46e302c11411567af4e">http://127.0.0.1:8000/activate/OQ/bnjmpy-22a214344550a46e302c11411567af4e</a></p> <p>Thanks for using our site!</p> After clicking on this link, I am of course taken to the browser, to the exact link where the DRF page is displayed in the browser. I want to display the Login page in React instead. I was thinking of redirecting from the backend to the frontend and there wywowalać getrequest to the activation link, or somehow in APIView redirect to the frontend login page.

I read that I need to have a def save(self, request) function as well and have tried to implement that as well. main app urls.py from django.contrib import admin from django.urls import path, include from django.views.generic import TemplateView urlpatterns = [ path('admin/', admin.site.urls), path('api/authentication/', include('authentication.urls')),] settings.py INSTALLED_APPS = \[ 'rest_framework', 'rest_framework.authtoken', 'allauth', 'allauth.account', 'dj_rest_auth', 'dj_rest_auth.registration', 'authentication',] SITE_ID = 1 AUTHENTICATION_BACKENDS = ( 'django.contrib.auth.backends.ModelBackend', 'allauth.account.auth_backends.AuthenticationBackend', ) REST_AUTH_REGISTER_SERIALIZERS = { 'REGISTER_SERIALIZER': 'authentication.serializers.CustomRegisterSerializer' } # Configure allauth to use email as username ACCOUNT_AUTHENTICATION_METHOD = 'username' ACCOUNT_EMAIL_VERIFICATION = 'none' ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_UNIQUE_EMAIL = True ACCOUNT_USERNAME_REQUIRED = True ACCOUNT_SIGNUP_PASSWORD_ENTER_TWICE = True ACCOUNT_USER_MODEL_USERNAME_FIELD = 'username' ACCOUNT_LOGOUT_ON_GET = True authentication app urls.py from django.urls import path from dj_rest_auth.views import ( LoginView, LogoutView, PasswordResetView, PasswordResetConfirmView ) from .views import CustomRegisterView urlpatterns = \[ path('register/', CustomRegisterView.as_view(), name='register'), path('login/', LoginView.as_view(), name='login'), path('logout/', LogoutView.as_view(), name='logout'), path('passwordReset/', PasswordResetView.as_view(), name='password_reset'), path('passwordResetConfirm/\<str:uidb64\>/\<str:token\>/', PasswordResetConfirmView.as_view(), name='password_reset_confirm'), \] serializers.py from rest_framework import serializers from allauth.account.adapter import get_adapter from django.contrib.auth.models import User from dj_rest_auth.registration.serializers import RegisterSerializer class CustomRegisterSerializer(RegisterSerializer): … -
Why the registeration.html form is not rendering in DJANGO?
New to DJANGO. I am having trouble with rendering my registeration.html page. This is my project structure auth_test | |-urls.py |-settings.py big_app | |-admin.py |-forms.py |-models.py |-urls.py |-views.py templates media static This is my application big_app. The auth_test folder urls.py is from django.contrib import admin from django.urls import path from big_app import views # from django.conf.urls import url, include ---> this is depreciated from Django 4.0 onwards from django.urls import include,re_path urlpatterns = [ re_path(r'^$', views.index,name='index'), re_path(r'^admin/', admin.site.urls), re_path(r'big_app/',include('big_app.urls')), ] now the urls.py of the big_app is from big_app import views from django.urls import include, re_path # TEMPLATE URLS app_name = 'big_app' urlpatterns = [ re_path(r'^register/$',views.register, name='register') ] The views.py has the code. from django.shortcuts import render from big_app.forms import UserForm, UserProfileForm # Create your views here. def index(request): return render(request, "big_app/index.html") def register(request): registered = False # breakpoint() if request.method == "POST": user_form = UserForm(data=request.POST) profile_form = UserProfileForm(data=request.POST) if user_form.is_valid() and profile_form.is_valid(): user = user_form.save() # hashing the password user.set_password(user.password) user.save() profile = profile_form.save(commit=False) # setting up the one to one relationship with the user present in the admin perspective profile.user = user if "profile_pic" in request.FILES: profile.profile_pic = request.FILES["profile_pic"] profile.save() registered = True else: print(user_form.errors, profile_form.errors) else: user_form … -
what does ', '.join(genre.name for genre in self.genre.all()[:3]) precisely do?
Hi I'am lerning Django web framework and I came acros this line of code: return ', '.join(genre.name for genre in self.genre.all()[:3]) source I want to know what precisely everything in this line does. I know that .join joins a tuple into the string with ', ' as a separator. But I have no idea how genre.name for genre in self.genre loop works. What does .all() function do and how [:3] connects with all of this. I tried searching what .all() does but I only found documentation for all(parameter). I tried searching what a for b in c loop does but I only found documentation for a in b. I know that [:3] return 3 values but I don't know how this connects with the rest of the code. -
Factory boy connect models to existing users
Im populating my database with dummy data, I have separate Profile, User, Picture model. How can connect them to use same users? class UserFactory(DjangoModelFactory): class Meta: model = User email = factory.Faker('email') first_name = factory.Faker('first_name') birthday = factory.Faker('date_object') age = factory.Faker('pyint', min_value=18, max_value=100) is_staff = False is_active = True class UserPhotoFactory(DjangoModelFactory): class Meta: model = UserPhoto user = factory.RelatedFactory(UserFactory) #???? order = factory.Faker('pyint', min_value=0, max_value=4) url = factory.Faker( 'random_element', elements=[x for x in ['https://picsum.photos/seed/picsum/200/300', 'https://picsum.photos/seed/pssss/200/300', 'https://picsum.photos/seed/picwum/200/300']] ) class ProfileFactory(DjangoModelFactory): class Meta: model = Profile user = factory.SubFactory(UserFactory) bio = factory.LazyAttribute(lambda o: FAKE.paragraph(nb_sentences=5, ext_word_list=['abc', 'def', 'ghi', 'jkl'])) In this case I'm calling in shell ProfileFacotry.create_batch(10) And that creates users and their corresponding profiles. Now I want to add UserPhoto to the mix that is related to USER via ForeignKey like this class UserPhoto(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) order = models.PositiveIntegerField(null=True) url = models.CharField(max_length=220) What I want to achieve is to get 10 users 10 profiles and let say 20 pictures 2 for each user
