Defining choices outside of model producess fields.E005 error [duplicate]
I have the following code in my models.py: from django.db import models from django.utils.translation import gettext_lazy as _ class Sport(models.IntegerChoices): SWIMMING = 0, _("Swimming") HIKING = 1, _("Hiking") RUNNING = 2, _("Running") class Manufacturer(models.Model): uuid = models.UUIDField(default=uuid4, editable=False) name = models.CharField( max_length=255, help_text="Manufacturer name as displayed on their website", ) url = models.URLField(blank=True) sport = models.PositiveSmallIntegerField(choices=Sport) class OrganisationClass(models.Model): uuid = models.UUIDField(default=uuid4, editable=False) class_name = models.CharField(max_length=64, blank=False) description = models.CharField( max_length=255, blank=False, ) sport = models.PositiveSmallIntegerField(choices=Sport) which produces the FAIClass.sport: (fields.E005) 'choices' must be an iterable containing (actual value, human readable name) tuples. when I run manage.py check and I don't understand why. I got the idea to do it based on this answer, I'd really appreciate if someone could help. -
django: contol access to pages by many to many relation
I have a problem for block access to not authorized user in specific pages. List of that users is stored in Many to Many model in Project object. Below is models.py class Project(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name="projects_as_owner", null=True) project_managers = models.ManyToManyField(User, related_name="projects_as_pm", blank=True) name = models.CharField(max_length=200) description = models.TextField(blank=True) date_of_insert = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name class Milestone(models.Model): project_fk = models.ForeignKey(Project, related_name="milestones", on_delete=models.CASCADE) name = models.CharField(max_length=200) description = models.TextField(blank=True) date_of_insert = models.DateTimeField(auto_now_add=True) def __str__(self): return self.name And views.py with class I have problem class NewMilestone(LoginRequiredMixin, generic.CreateView): model = Milestone fields = ['name', 'description'] lookup_url_kwarg = 'p_id' template_name = 'main/new_milestone.html' # ... two functions, that work good, not important here ... def get_queryset(self): qs = super(NewMilestone, self).get_queryset() project = Project.objects.get(id=self.kwargs['p_id']) if(qs.filter(project_fk__owner=self.request.user).exists() or User.objects.filter(id=self.request.user.id).filter(projects_as_pm__id=project.id).exists()): return qs else: return Http404("You are not authenticated to this action") Objective here is here to allow authenticated users (owner and project manager/s) to enter this view and for anybody else show info about declined access. Problem is that, that worked well on checking ONLY ownership. When I added that part about project manager(after 'or') program allows any user to access this view with link. I tried many configuration for that second 'if' statement every single one … -
Django, Docker, Nginx, cant find static file
I just cant wrap my head around how to properly write a nginx.conf file. My nginx container in docker keeps giving me error 2022/10/03 12:33:28 [error] 31#31: *1 open() "/usr/src/app/staticblog/style.css" failed (2: No such file or directory), client: 172.18.0.1, server: , request: "GET /static/blog/style.css HTTP/1.1", host: "localhost:1337", referrer: "http://localhost:1337/profile/login" nginx.conf file upstream blog { server back:8000; } server { listen 80; location /{ proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://blog; } location /static/ { alias /usr/src/app/static; } location /media/ { alias /usr/src/app/media; } } I feel like im just writing conf file wrong, but I cant wrap my head around directories in docker and how to properly manage them UPDATE: as @HemalPatel mentioned, I messed some slashes.

I am trying to use a value 'start_index' from paginator's 'get_page()' object.

Share Custom User model between two Django projects (same db)
i have two Django project, sharing the same DB (postgres) The first one is an onboarding project for the users where i store the user data. The second one is the project where all the entities related to the user are. For example project one has only Users, project two has Cars and those two models are going to be related. I want to get the users from the first project and "use" them in the second one. I read some articles on how to do this, it seems that i should recreate the User model on project 2 and fake the migrations but i don't really like this way. I'm new to Django can you please help me understanding the best practice to achieve this? -

wait for an asyn_task to complete or complete it in background
I have some functions in my Django application, that takes lot of time (scraping using proxies), it takes sometimes more than 30sec and is killed by gunicorn and AWS server due to timeout. and I don't want to increase the timeout value. A solution that came to my mind is to run these functions as a async_task using django-q module. Is it possible to do the following: when a view calls the long function, Run the function in async way if it returns a result in a pre-defined amount of time return the result to user. If not, return an incomplete result and continue the function in the background (The function changes a model in the database) no need to notify the user of changes. -
Using Values after Cast and Replace in Django ORM
Dummy data: field_1 price lot 1 1,333.00 lot 1 348.39 lot 2 98.00 The objective is to add the values of price Since price are strings representing numbers, Cast and Replace are used to remove the thousand comma separator and perform the sum. If I want to make the total sum, it works without any problem: total_price = ( myModel.objects.filter(status='Active', project_id=pid) .annotate( cleaned_total=Replace('price', Value(','), Value('')) ) .annotate(float_total=Cast('cleaned_total', FloatField())) .aggregate(Sum('float_total')) ) total_price output: {'float_total__sum': 1779.39} The problem is that I would like to group the sum, and for that I use .values('field_1') and I would like the result to be something like this: <QuerySet [{'field_1': 'lot 1', 'float_total__sum': 1681.39}, {'field_1': 'lot 2', 'float_total__sum': 98.0}] What I've tried: total_price_grouped = ( myModel.objects.filter(status='Active', project_id=pid) .values('field_1') .annotate( cleaned_total=Replace('price', Value(','), Value('')) ) .annotate(float_total=Cast('cleaned_total', FloatField())) .aggregate(Sum('float_total')) ) But unfortunately that gives me the following result: {'float_total__sum': 1779.39} If I don't use Cast and Replace, the sum is grouped correctly as desired but those values with thousand comma separator are not added correctly: total_price_grouped = myModel.objects.filter(status='Active', project_id=pid).values('field_1').annotate(sum=Sum('price')) How could I do the sum by combining values, replace and cast? -

Django model filter based on boolean field
I have a user model which has fields like these, is_active = models.BooleanField() date_joined = models.DateTimeField(auto_now_add=True) resigned_date = models.DateTimeField(blank=True, null=True) Where resigned_date will be None if is_active field is True. If is_active field is False then the resigned_date field will have the date. I think I can explain it. What I want is to queryset of users based on some DATE and is_active field. More clearly I want to get the list of employee that (is active and joined_date is less that or equal to the current date) and (is not active and resigned_date is greater that the current date) The query I have written so far: users = user_models.User.objects.filter( Q( is_active=True, date_joined__month__lte=month, date_joined__year__lte=year, ) & Q( is_active=False, resigned_date__month__gt=month, resigned_date__year__gt=year, ) ) But this is not working. It is not returning any users. How can I achive this? Thanks -
