Static Files not working on PythonAnywhere - but working on local server
I'm deploying My web app on Pythonanywhere. After deployment, static files are not shown on it. While StaticFiles are working fine on Local Server. Lets just say staticfiles contain an image which is shown on Local Server on Home Page but doesn't show on pythonanywhere after deploying. What could be the issue? I tried adding static folder in each of my app, also as a global folder. Also, configured it on settings.py correctly as well. STATIC_URL = "static/" STATICFILES_DIRS = [ BASE_DIR / 'static', ] Here's the link to my website: http://syedhamza10.pythonanywhere.com/ It is supposed to show a logo along with The Vision Realtor -

Django form using DateTimeRangeField will not validate
When trying to check if the form is valid using .is_valid(), I get AttributeError: 'list' object has no attribute 'strip' for my DateTimeRangeField. I am using RangeWidget(forms.SplitDateTimeWidget(date_attrs={"type": "date"}, time_attrs={"type": "time"},),), with postgres db. I switched the backend from sqlite3 to postgres so I could use the DateTimeRangeField and the debugger shows the correct information in the POST request. Do I need to switch my datetimerange column/field into two columns, datetime_start and datetime_stop? Or is there another way to validate that I have missed? Should I just separate out the range into a separate form and use a key to connect it to my current form? I would like to add the ability to add many time ranges in the same form in the future. -
drf-spectacular generate got multiple values for keyword argument 'context' error
Django 3.2/ DRF 3.14.0 When forming a page with api documentation, an error is observed in the console got multiple values for keyword argument 'context' Code sample class CustomBatchView(mixin.ListModelMixin, mixin.CreateModelMixin, VendorViewSetMixin): def_serializer(self, *args, **kwargs): context = {'request': self.request} if self.action == 'create': return BatchCreateSerializer(*args, context=context, **kwargs) elif self.action in ['update', 'partial_update']: return BatchUpdateSerializer(*args, context=context, **kwargs) else: return BatchSerializer(*args, context=context, **kwargs) The problem is that when Viewsets in DRF calls get_serializer, it passes context inside kwargs. So when I try to pass the context separately, there is a conflict. The reason why I need separate context attribute is because using this logic further in self.context.get('request') So if implement this if 'context' in kwargs: del kwargs['context'] inside get_serializer All work perfect. Such a problem does not arise with business logic. Only at the moment of forming API documentation. What can this be related to and how can it be fixed? -

django is expecting DNS record content in ALLOWED_HOSTS
i have a django app deployed on northflank and i register the domain on namecheap and am using cloudflare for dns management, i added the domain to django's setting.ALLOWED_HOSTS ALLOWED_HOSTS = ['www.domain.com'] and also configured the domain on northflank and also configured the dns record on cloudflare usin g the dns configuration settings northflank provided Record type CNAME CNAME/ALIAS/APEX Record name www .domain.com Expected Record Content www.domain.com.t16j-p585.dns.northflank.app Current Record Content No record found everything is working fine but django keeps throwing this error: DisallowedHost Invalid HTTP_HOST header: 'www.domain.com.t16j-p585.dns.northflank.app'.

If statement in Django Model related to an other model
I'm building a Django Python App and I am facing a problem. For some reason, I would like to implement a different price (Produit.PU_HT_WH) according to the customer (client) type (retailer or wholesaler (booleans). I would like to implement it to my models.py so that I don't have to changes Models.py (Produit) : class Produit(models.Model): id_Prod = models.CharField(max_length=200, null=True) EAN = models.IntegerField() PU_HT_WH = models.FloatField(null=True) denomination = models.CharField(max_length=200, null=True) def __str__(self): return self.id_Prod def PU_HT(self): if self.client.retailer: PU_HT= (self.PU_HT_WH/ 0.85) else : PU_HT = self.PU_HT_WH return PU_HT Models.py (Client) : class Client(models.Model): id_Client = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE) nom_client = models.CharField(max_length=200, null=True) prenom_client = models.CharField(max_length=200, null=True) raison_sociale = models.CharField(max_length=200, null=True) retailer = models.BooleanField(default=False, null=True) def __str__(self): return self.nom_client My goal here is that I just have to replace every " {{prod.PU_HT_WH|floatformat:2}}€ " to " {{prod.PU_HT|floatformat:2}}€ " to display prices according to the customer. The website works only on @login_required so I would like that the customer only sees his price. I hope that I've been enough understandable !

Django CheckConstraint failing
I'm creating a custom user-model where every user needs a company assigned, unless they are a superuser or staff. To accomplish this, I'm adding 3 CheckConstrains as seen below: class CustomUser(AbstractUser): ''' Custom User class, username and email are required. Company is required except for staff and super users ''' company = models.ForeignKey(Company, on_delete=models.PROTECT, null=True, blank=True) class Meta(AbstractUser.Meta): constraints = [ CheckConstraint( check=Q(is_superuser=False, is_staff=False, company__isnull=False), name="user_must_have_company", ), CheckConstraint( check=Q(is_staff=True, company__isnull=True), name="staff_cannot_have_company", ), CheckConstraint( check=Q(is_superuser=True, company__isnull=True), name="superuser_cannot_have_company", ), ] Desired behaviour is: Super-users and Staff users cannot have a company all 'normal' users need to have a company set. However, all initial conditions fail on the same CheckConstraint user_must_have_company. user = CustomUser.objects.create(username='staffuser', is_staff=True, company=None) IntegrityError: CHECK constraint failed: user_must_have_company company = Company.objects.create(name='Test') user = CustomUser.objects.create(username='normal_user', is_staff=True, company=company) IntegrityError: CHECK constraint failed: user_must_have_company user = CustomUser.objects.create(username='superuser', is_superuser=True, company=None) IntegrityError: CHECK constraint failed: user_must_have_company What am I missing? -

Google OAUTH2 using django-socialauth
I have a django project in which i'm using django-social-auth to implement google and facebook. From the side it seems to work quite well as i've been able to register and login using it. However, as soon as i turn google API into production, i get an error of mismatch_url. In the credentials => Authorized redirect URIs i have this url: https://www.swimseekr.com/social-auth/complete/google-oauth2/ but when i try to login, google give me this error: which shows an http url: You can't sign in to this app because it doesn't comply with Google's OAuth 2.0 policy. If you're the app developer, register the redirect URI in the Google Cloud Console. Request details: redirect_uri=http://www.swimseekr.com/social-auth/complete/google-oauth2/ so if i go back to testing mode, and remove the 's' from http, and try to login, it works again. Anyone, can help me on this? Thank you. -
How to send ajax post request for a video file in Django?
I want to send an ajax post request to a django view for a video file. I am creating a simple page where the user could record his camera and audio. After the user stops recording, the recorded video file would then automatically be sent to a backend view where I would save it to the database.

query to count reverse foreign fields and reverse manytomany field
In my application there are users and users can block each other. I want to save each action taken by a user. In an action, a user could perform multiple ban operations on other users. That is why the Action table has a user_list. Now I want to find the total number that other users target the specific user. For example User_5 was targeted by other users 8 times. models.py class BanMode(models.Model): ban_mode = models.CharField(max_length=10, blank=False, null=False) class CustomUser(models.Model): custom_name = models.CharField(max_length=96, blank=False, null=False) custom_id = models.IntegerField(blank=False, null=False) class Action(models.Model): taken_by = models.ForeignKey(CustomUser, on_delete=models.CASCADE, blank=False, null=False) ban_mode = models.ForeignKey(BanMode, on_delete=models.PROTECT, blank=False, null=False) user_list = models.ManyToManyField(CustomUser, blank=False, null=False) Following code successfully finds the total number of actions on the user performed by other users (users not unique). CustomUser.objects.annotate(banned_by_count=Count('user_list', distinct=False)) However, I want to apply a filter. I want to find the total number of actions (for example actions whose ban_mode is 1) on the user performed by other users (users not unique). This query does not work. CustomUser.objects.annotate(banned_by_count=Count('user_list', distinct=False, filter=Q(action__ban_mode__ban_mode="BAN"))) -

When a Django custom field accepts a class-type parameter, it causes infinite AlterField migrations
I'm trying to define a custom field in Django, and I wanted to initialize it with a helper object. The field class receives the helper object an init parameter, and stores internally. Unfortunately, this results in an odd consequence: As soon as any model makes use of this field, Django considers it to always be in an altered state, and therefore to always have changes requiring new migrations. Is there any way to solve this, or is it just a blanket rule that a custom field can only be initialized with primitives? Walkthrough and Detail I'm defining a simple custom Django field, as follows: class FooField(CharField): def __init__(self, foo : Foo, *args, **kwargs) -> None: self.foo : Foo = foo super().__init__(*args, **kwargs) def deconstruct(self): name, path, args, kwargs = super().deconstruct() kwargs["foo"]=self.foo return name, path, args, kwargs Where Foo is a simple object, e.g.: class Foo: def __init__(self, n): self.n=n def __repr__(self): return f"Foo({self.n})" Now I add this new field type to a model (having written supporting class FooSerializer and method default_foo(), to support migrations -- supporting code below): from django.db import models from .utils.foo_field import Foo, FooField, default_foo fooA= Foo(1) fooB = Foo(2) class MyModel(models.Model): n1 = models.IntegerField() # preexisting … -
Type hinting with cyclic dependency
I am building a Django/DRF application and have the following models: class Company(models.Model): some_field = models.TextField() some_method(user): pass class User(AbstractUser): company = models.ForeignKey(Company, on_delete=models.CASCADE) The method some_method of the company model uses a user as input. The code itself works fine. However, how can I type hint this parameter to get IDE support / code completion in PyCharm? Declaring it like some_method(user: User): yields an "Unresolved reference" error makes sense since the user class is declared further down in the file. Is there a workaround or do I have to live without code completion? -
