Django models how to fix circular import error?
I read about solution for the error (write import instead of from ...) but it doesn't work I think because I have a complex folder structure. The folder structure quiz/models.py import apps.courses.models as courses_models class Quiz(models.Model): lesson = models.ForeignKey(courses_models.Lesson, on_delete=models.DO_NOTHING) # COURSE APP MODEL IMPORTED courses/models.py import apps.quiz.models as quiz_models class Lesson(models.Model): ... class UserCompletedMaterial(models.Model): ... lesson = models.ForeignKey(lesson) quiz = models.ForeignKey(quiz) # QUIZ APP MODEL IMPORTED How you can see I just can't keep it together or something else.. Because I think the UserCompletedMaterial model is a part of courses app -
How can I upload multiple files in to a Django model?
I'm trying to make an LMS system with Django and now I need to upload multiple pdf files to the curriculum of the class. I can upload one file with the OnetoOne field in the Django model but not more. When I try to add another material for the same class it says Upload materials with this Uploaded class already exists. This is my model code. class UploadMaterials(models.Model): name = models.CharField(max_length=255) uploaded_class = models.OneToOneField(Class, on_delete=models.CASCADE, related_name='upload_materials') upload_material = models.FileField(upload_to=rename, null=True) class Meta: verbose_name_plural = "Materials" I need to upload the materials and be able to view them in the template. like...... {% for material in class.materials %} <h1>{{ material.name }}</h1> {% endfor %} I tried the Django ForeignKey instead of OnetoOne and was able to create multiple materials for the same class but could not figure out how to access them from the template. What I want to know is how to upload multiple files to the same class and how to access them in the template. Thank you! -

Problem with timezone in Django ORM, datetime value differs from the value stored in the table
I have stored some data into PostgreSQL database. Here is the corresponding Django model: from django.contrib.gis.db import models class PrecipitationContourDjango10d(models.Model): value = models.FloatField(blank=True, null=True) geometry = models.PolygonField(blank=True, null=True) date = models.DateTimeField(blank=True, null=True) window_no = models.CharField(max_length=10, blank=True, null=True) color = models.CharField(max_length=20, blank=True, null=True) def __lt__(self, other): if self.date < other.date: return True return False class Meta: db_table = 'precipitation_contour_web_service10d' Here is some rows that are stored in the table: As you can see the datetime value for the row with id=5921 is 2021-05-07 21:00:00-07. However when I retrieve that row using the Django ORM, its datetime field will change: from data.models import PrecipitationContourDjango10d row = PrecipitationContourDjango10d.objects.get(id=5921) How can I solve this issue? Thanks. -

How to achieve Waiting Room to match people 1-on-1 with Django Channels?
I could not find any starter basic solution for this problem. My thought process right now that when users join to the queue they will be added temporarily to a WaitingRoom model. Then there is a 10 seconds delay for waiting, the next step that they will be randomly match with each other. My problem with this that it won't prevent that multiple users would be matched up with each other. This is my current messy solution. It sends out to everyone in the queue and checks on the frontend if the current user is actually in the pair. class WaitingRoomConsumer(AsyncConsumer): @database_sync_to_async def get_waiting_room(self, user): room = WaitingRoom.objects.all().exclude(user=user) serializer = WaitingRoomSerializer(room, many=True) return serializer.data @database_sync_to_async def add_to_waiting_room(self, user): if (WaitingRoom.objects.filter(user=user).count() == 0): return WaitingRoom.objects.create(user=user) @database_sync_to_async def get_user_id(self, username): return User.objects.get(username=username).id @database_sync_to_async def remove_from_waiting_room(self, user): room = WaitingRoom.objects.get(user=user) return room.delete() async def websocket_connect(self, event): current_user = self.scope['user'] self.room_obj = await self.add_to_waiting_room(current_user) self.room_name = "WAITING_ROOM" #f'waiting_room{self.room_obj.id}' await self.channel_layer.group_add(self.room_name, self.channel_name) await self.send({ 'type': 'websocket.accept' }) msg = json.dumps({ 'type': 'joined', 'username': current_user.username, }) await self.channel_layer.group_send( self.room_name, { 'type': 'websocket.message', 'text': msg } ) print(f'[{self.channel_name}] - You are connected.') await self.recommend_candidate() async def websocket_receive(self, event): print(f'[{self.channel_name}] - Recieved message. - {event["text"]}') msg = event.get('text') … -

Django Question 'ModelChoiceField' object has no attribute 'use_required_attribute'

Django best practice to display data to template
I have a Django template that I would like to display a users transactions and I would like to know the best practice for displaying data from my database to the template. Should I implement a form that sends a users 'Order by' value and make an SQL query and then return those results back to the user or should I just handle all the processing via JavaScript? What is the best practice?

I have installed python via homebrew on my macbook (macOS Big Sur 11.2.3). Yes, I know, it's outdated, but I need it for some old projects. I use virtualenv to seperate stuff. When I try to run ./manage.py runserver I got this error: ERROR:root:code for hash md5 was not found. Traceback (most recent call last): File "/usr/local/Cellar/python@2/2.7.15_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/hashlib.py", line 147, in <module> globals()[__func_name] = __get_hash(__func_name) File "/usr/local/Cellar/python@2/2.7.15_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/hashlib.py", line 97, in __get_builtin_constructor raise ValueError('unsupported hash type ' + name) ValueError: unsupported hash type md5 ERROR:root:code for hash sha1 was not found.

Thanks.
