Django REST - rest_auth custom fields not being serialized
I'm using Django REST with the rest_auth package, and I'm having an issue with serializing custom fields when registering a new user. The field "is_employer" is always set to false even when you set it to true. Also in the API if you set the is_employer checkbox to true, it doesn't change anything. I added it in models, serializers and adapter, what am I missing? MODELS: class MyUserManager(BaseUserManager): def create_user(self, email, password=None): if not email: raise ValueError('Users must have an email address') user = self.model( email=self.normalize_email(email), ) user.set_password(password) user.save(using=self._db) return user def create_superuser(self, email, password): user = self.create_user( email=self.normalize_email(email), password=password, ) user.is_admin = True user.is_staff = True user.is_superuser = True user.save(using=self._db) return user class CustomUser(AbstractBaseUser): username = None first_name = None last_name = None email = models.EmailField(verbose_name='email address', max_length=255, unique=True) date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True) last_login = models.DateTimeField(verbose_name='last login', auto_now=True) is_admin = models.BooleanField(default=False) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) is_employer = models.BooleanField(default=False) USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] objects = MyUserManager() def __str__(self): return self.email def has_perm(self, perm, obj=None): return self.is_admin def has_module_perms(selfself, app_label): return True; SERIALIZERS: from django.contrib.auth.hashers import make_password from rest_framework import serializers from rest_auth.registration.serializers import RegisterSerializer from users.models import CustomUser class CustomRegisterSerializer(RegisterSerializer): def get_cleaned_data(self): … -
django multiple models with same foreign key
I have django app that is tracking contracts, locations, and products for various clients. Contracts, Locations each reference the client with a ForeignKey. class Location(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE) ... class Contract(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE) ... I also have a product that will be deployed in a location, on a contract, for a client. I need to include client in product because the reference is used to secure the record to that client. class Product(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE) contract = models.ForeignKey(Contract, on_delete=models.CASCADE) location = models.ForeignKey(Location, on_delete=models.CASCADE) .... What is the best way to make sure a product is never created that contains a different client reference across all 3 models? I was thinking I could use a pre_save signal but I would rather use a database constraint but I don't see a database constraint to force this. -

How to use saved card to pay with stripe?
I'm trying to build a checkout flow where the user can pay using a new card or a card that is saved to the customer object. I'm struggling on how to actually use the saved card details to create a charge. This is what I'm working with at the moment.

Heroku duplicate key value violates unique constraint (django)
Today I deployed my django app on Heroku for the first time (following this tutorial). The problem is that when I want to modify or add something to the database, I get an Integrity Error which says: duplicate key value violates unique constraint "app_professore_pkey" Where Professore is the name of the Model I tried to modify. I’ve searched a bit online and I’ve seen that probably is because I developed the app on my PC using SQLite and now, on Heroku, it uses PostgreSQL, and those 2 databases works differently. Actually, I don’t have a lot of experience with databases (almost no experience) so I don’t know how to fix this... Maybe modifying something on the Professore model? Or typing something in the Heroku console? This is the error screen I get, if you need it to help me :) Thanks in advance and tell me if I wasn’t clear on something (I’m new to StackOverflow too) -

Possible to use distinct() with attributes created via extra() in Django ORM?
Let's say you have the following Django ORM query: cars = CarModel.objects.only( 'car__car_id', 'car__cardate', 'car__title', 'car__location', 'car__quote', 'car__key', 'car__cartype_id', 'maker__lastname', 'maker__firstname', 'maker__middlename', 'maker__nickname', ).select_related( 'car', 'maker', ).extra( select={ 'is_position_paper': 'cartype_id = 7', 'is_null_date': 'cardate IS NULL', 'shorttitle': extra, }, ).filter(**kwargs).distinct(sort_order_for_distinct, 'car__car_id').order_by(sort_order, 'car__car_id') My understanding is that, whatever I've included in order_by() I have to also include, in the same order, in distinct(). However, distinct doesn't like the attributes being created in extra(). If I try and include these attributes in the order_by() as I would like, such as: .order_by('is_position_paper', 'is_null_date', sort_order, 'car__car_id') I get the error: Cannot resolve keyword 'is_position_paper' into field So that means that the attributes created via extra() just aren't going to be available to use with distinct()? Is there any alternative approach here? Really all I'm trying to do is dedupe this entire queryset by car__car_id, that's it, whilst having order_by('is_position_paper', 'is_null_date', sort_order, 'car__car_id') Unfortunately I'm stuck on Django 2.1 with this. Also, using Postgres as the db. -

django adds unwanted key to my users table. How do I get rid of it at the source?
Latest Django. When I look at the database I see the following keys created for my users table: I am responsible for explicitly adding the user_unique_email_delete_token using the UniqueConstraint on my User model -- as my Users are soft-delete, but I have no idea where users_email_key comes from or how I can stop it from being created. It gets in the way of me having two records with identical email but different delete_token (on soft deleted rows). This should be perfectly ok in my app. Any ideas how I can get rid of this key, and not by modifying the database schema externally? I need it not to be created in the first place with migrate. -
AWS-Xray SDK is not getting disable in Python

Although I can turn it off using global_sdk_config.set_sdk_enabled(False) but due to requirements constraint, I have to enable or disable it via environment variables.

Code looks currently something like this: from captcha.fields import ReCaptchaField from captcha.widgets import ReCaptchaV3 class AccountForm(forms.ModelForm): name = forms.CharField(validators=[MinLengthValidator(3)], error_messages={'invalid':_("Please enter a name.")}) terms = forms.BooleanField() # ReCaptcha v2 #captcha = ReCaptchaField( # public_key= settings.RECAPTCHA_PUBLIC_KEY, # private_key= settings.RECAPTCHA_PRIVATE_KEY, #) # Recaptcha v3 captcha = ReCaptchaField( public_key=settings.RECAPTCHA_PUBLIC_KEY_V3, private_key=settings.RECAPTCHA_PRIVATE_KEY_V3, widget=ReCaptchaV3( attrs={ 'required_score': 1.0, } ) ) So nothing there yet. What I try to achieve is a failing v3 to show the v2 instead. This is more a general question if it is possible and where to start. Thanks -
Angular universal SSR not displaying the angular assets folders images while serving it from Django
I have used Angular Universal for SSR(Server Side Rendering) of my angular application.

I got 2 folders namely "browser" "server" and "server.js" file. Browser folder contents are equivalent to dist folder content what we usually get by ng build --prod. But I have done the same but using Angular Universal. Now coming to the Django part: STATIC_URL = '/static/' MEDIA_URL = '/media/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [ os.path.join(BASE_DIR, '<my_proj_dir>/static'), ] I have also created a simple app to render the index.html page of angular: class FrontEndRenderView(TemplateView): def get(self, request, **kwargs): return render(request, 'index.html', context=None) Next I copy my browser i.e dist folder content inside the above app template(only the index.html) and static files(different js scripts) Next I ran the python manage.py collectstatic to get all my static files into the root directory static folder which I already set in the settings.py and serve it from there. Modified the index.html: {% load static %} <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> … -
