Django 3 'User' object has no attribute 'admin'
SITUATION I am modifying this GitHub project from this YouTube Series and this is a demo how the original application runs. My goal is to add settings option for Merchant(in the code Admin or AdminUser) accounts in the marketplace, because in the original project only buyers have the option to add image and their contact details.

Multiple Images Upload using Django Claases

Setting up deployment for Django+React project having each run on different ports with Nginx
I am developing a Django (for Web API serving) + React (frontend purpose) project where the codebase for both Django and React are consolidated in a main project folder, meaning both are on the same git repository, as below: . +-- _backend | +-- _config | | +-- settings.py | | +-- urls.py | | +-- wsgi.py | +-- _sample_app | +-- _static | +-- _media | +-- manage.py | +-- requirements.txt +-- _frontend | +-- _public | +-- _src | | +-- App.css | | +-- App.js | | +-- index.js | +-- babel.rc | +-- package-lock.json | +-- package.json | +-- webpack.config.js Now, I would like to implement the recommended way of integrating both technologies: Django as a standalone backend app that only serves API (no UI, assets, templates) React as a standalone SPA whose purpose is to serve the frontend (UI, web pages, assets, etc.) Which means that Django will be starting on its own port and React also on its own. Now, during development I could do: React on localhost:3000 Django on localhost:3001 However, I am not pretty sure how to deploy using the above setup on production server. I will be using Nginx for this … -

Django says 'The _imaging C module is not installed' when I try to add images to database entries
I am working on ubuntu server,and this is my first web development project based on django. After I have hosted the site with apache2, mod_wsgi , the site is running but I have encountered two problems: 1)All the users and other database entries have been lost. I have tried makemigrations and migrate , but it didnt solve it. 2) I tried to add all the entries again, but now there is a problem with adding images to the ImageField in the databases using Pillow module.It says The _imaging C module is not installed . The error takes place in sites-packages\PIL\Image.py (I am using a virtualenv) somewhere around line 93 which is from . import _imaging as core .

No changes, the error still occurs. 2)Tried installing libjpeg with the following code- sudo apt-get install libjpeg-dev .

How to configure Cookiecutter Django to use Gmail SMTP
Can anyone help me with to configure my django cookiecutter production setup to work with Gmail SMTP. I have deployed my application using docker. Cookiecutter gives you to configure your app to anymail providers. I've chosen Mailgun however I didn't have an email address that has been verified by my domain provider. So, I couldn't register any user to my app because ( https://cookiecutter-django.readthedocs.io/en/latest/deployment-with-docker.html#configuring-the-stack) here it says you can't :) I have tried to override the default email verification setting from "mandatory" to "none". However, it still threw 500. In below, I've added all-auth settings. I had to decide either to buy an email address or configure my app to work with Gmail Smtp or get rid of this email verification process. settings/base.py ACCOUNT_ALLOW_REGISTRATION = env.bool("DJANGO_ACCOUNT_ALLOW_REGISTRATION", True) # https://django-allauth.readthedocs.io/en/latest/configuration.html ACCOUNT_AUTHENTICATION_METHOD = "username" # https://django-allauth.readthedocs.io/en/latest/configuration.html ACCOUNT_EMAIL_REQUIRED = True # https://django-allauth.readthedocs.io/en/latest/configuration.html ACCOUNT_EMAIL_VERIFICATION = "none" # https://docs.djangoproject.com/en/dev/ref/settings/#email-backend EMAIL_BACKEND = env( "DJANGO_EMAIL_BACKEND", default="django.core.mail.backends.smtp.EmailBackend" ) Any way to get rid of this 500 would be awesome. -
How to authenticate fsspec for azure blob storage
From a django REST API view I am trying to access a file that is stored in an azure storage blob. I would like to open it without downloading it into a file, as shown here. Read access is sufficient. For this I scetched out my view like so: import os from fsspec.implementations.http import HTTPFileSystem @api_view() def my_view(request): url = "https://storageaccount.blob.core.windows.net/container/" filename = "file.f" fs = HTTPFileSystem( container_name=os.environ["AZURE_STORAGE_CONTAINER"], storage_options={ "account_name": os.environ["AZURE_STORAGE_ACCOUNT"], "account_key": os.environ["AZURE_STORAGE_KEY"], }, ) with fs.open(url + filename, "r") as fobj: ds = somehow.open_dataset(fobj) return Response({"message": "Data manipulated"}, status=200) This gives a FileNotFoundError. My questions are: Is this even possible with azure blob storage? If not, what would be the closest thing? How would I authenticate the HTTPFileSystem? I feel like I more or less made those keywords up but wasn't able to find any information about it... -
Looping through nested dicts in Django Template
I have a nested dict that I am passing as context to a template of the following structure: cWeeks{ 1: { 'receivables': { 'customer': 'x', 'amount': 'y', ...} 'payables': { 'customer': 'x', 'amount': 'y', ...} } 2: { etc } } In my template I have a for loop iterating over each number and then another nested for loop that should iterate over all items in 'receivables'.

Django - How to join two querysets with different key values (but from same model)

How do I extend my Django Default UserCreationForm?

How do I properly extend this registration, in a way that the login is still the same? -
Is there a way of triggering an action when a specific field is changed in Django models
I am looking for a way to trigger an action whenever a specific field on a model is changed, regardless of where it is changed. To add some context, I have been experiencing an elusive bug, where occasionally a date field is being set to the 13th of January 2020, I have absolutely no idea where in the codebase this is happening, it is also happening seldom enough that I have not been able to pick up any pattern as to what could be causing it. What I would like to do is trigger some kind of an alert whenever this field is changed to the 13th of Jan 2020, so I can attempt to isolate what is causing it. -

Having these models: class AccidentJob(models.Model): name = models.CharField(max_length=50) class Accident(TimeStampedModel, models.Model): job = models.ForeignKey(AccidentJob, on_delete=models.CASCADE) I want something like this: [ {'job__name': 'Auxiliar de surtido', 'count': 2}, {'job__name': 'Técnico de mantenimiento', 'count': 1} ] but I am getting this: [ {'job__name': 'Auxiliar de surtido', 'count': 1}, {'job__name': 'Auxiliar de surtido', 'count': 1}, {'job__name': 'Técnico de mantenimiento', 'count': 1} ] This is my query: from django.db.models import Count Accident.objects.values( "job__name" ).annotate( count=Count('job__name') ).values("job__name", "count") I can do it with Python, but I would prefer having PostgreSQL do the work. -
Django form field values filter by multiple queries
I am working with form logic now and my task sounds pretty easy - I need to implement form with dependent fields: 1) Country 2) Region 3) District (area) So I have my simple models: class CountryModel(models.Model): name = models.CharField('Country name', unique=False, max_length=128, blank=False, null=False) class RegionModel(models.Model): name = models.CharField('Region name', unique=False, max_length=128, blank=False, null=False) country = models.ForeignKey(CountryModel, on_delete=models.CASCADE, blank=True, null=True) class DistrictModel(models.Model): name = models.CharField('District name', unique=False, max_length=128, blank=False, null=False) region = models.ForeignKey(RegionModel, on_delete=models.CASCADE, blank=True, null=True) class FormModel(MetaModel): country = models.ForeignKey(CountryModel, on_delete=models.CASCADE, blank=True, null=True) region = models.ForeignKey(RegionModel, on_delete=models.CASCADE, blank=True, null=True) area = models.ForeignKey(AreaModel, on_delete=models.CASCADE, blank=True, null=True) It means that District queryset is depends on chosen Region and Region queryset is depends on chosen Country. I put my logic in the init form method and it looks like this: class SignCreateForm(ModelForm): data_url = '/sign-form-data/' class Meta: model = FormModel fields = ['country', 'region', 'district'] dependencies = {'district': ('region', 'country'), 'region': ('country',)} class Media: # ajax form refreshing script js = ('js/formset.js',) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if self.is_bound: if self.data['country']: self.fields['district'].limit_choices_to = {'country': self.data['country']} apply_limit_choices_to_to_formfield(self.fields['district']) Dut it doesn’t works and raises an error: "Cannot resolve keyword 'country' into field. Choices are: id, name, region.." The question is: Is there … -
Wagtail admin_order_field attribute not sorting correctly
I have admin_order_field attribute set on method in ModelAdmin class but it's giving wrong sort results.
