Connecting a Neo4j graph database to a Django REST API app
I am trying to connect a remote Neo4j database to a Django app with a REST API. I am trying to specify the database in the settings.py file using the following code: DATABASES = { 'default': { 'NAME': 'papers.db', 'ENGINE': 'django.db.backends.sqlite3', 'USER': '', 'PASSWORD': '', 'PORT': '', }, } I would like to know: What python libraries need to be installed in order to do this? What is the 'ENGINE' that needs to be specified in the code above? The Neo4j database has a URI, but does not provide us with an IP address - am I able to use this URI? I am confident that I know what the other parameters need to be. Thanks in advance -

Can i use Django Admin for the user interface when there will only be 2-3 users?
i am working on a project where i am creating a project management webapp for a small team (4-5 users). They will use it mainly for data management (CRUD operations for projects, resources, work hours, budgets etc.) and creating reports. For the CRUD part of the application i want to use Django Admin. Only 2-3 users will apply CRUD operations on the data. So i want to call them "administrators" and use the built-in Admin app because it literally has all the functionalities i need. It will save a lot of time and costs which is very important for this project I read that Admin is only meant for site administrators and this is not recommended. My question is: With this use case for the application can i use a Django admin app as a part of the User interface? Thanks in advance -
convert ManyToManyField to ForeignKey in Django
I have 3 models: class Series(models.Model): . . . series_name = models.CharField(max_length=50, unique=True) class Lists(models.Model): . . name = models.CharField(max_length=50, unique=True) class Article(models.Model): . . . lists = models.ForeignKey(Lists, blank=True, null=True, related_name='article_has', on_delete=models.CASCADE, default=None) series = models.ManyToManyField(Series, related_name='series', blank=True) is_published = models.BooleanField(default=False) Initially I created some Articles without 'lists' field. Now i want to add the 'Lists' field to the Article model but I am running into errors after makemigrations and migrate. I did the following: python manage.py makemigrations blog python manage.py migrate python manage.py makemigrations --empty blog modified the new empty generated migration file as follows: # Generated by Django 4.0.3 on 2022-05-03 13:54 from django.db import migrations def migrate_m2m_to_fk(apps, schema_editor): Article = apps.get_model("blog", "Article") for article in Article.objects.all(): article.lists = None article.lists.save() class Migration(migrations.Migration): dependencies = [ ('blog', '0001_initial'), ] operations = [ migrations.RunPython(migrate_m2m_to_fk) ] python manage.py migrate and at the step 5 I get the following error due to Article.objects.all() : MySQLdb._exceptions.OperationalError: (1054, "Unknown column 'blog_article.lists_id' in 'field list'") -
Django collectstatic to look for assets directory in every app in django project
Currently I have 6-7 apps present inside my Django project. In settings.py for STATICFILES_DIRS I need to specify assets directory full path present inside all my apps which is cumbersome in case when I increase my apps everytime I need to add the path here. Isn't there one setting with which I can specify just the assets folders and the collectstatic command will look for static files inside assets in all my apps? This is what I currently have: STATICFILES_DIRS = [ BASE_DIR / "app1/templates/assets", BASE_DIR / "app2/templates/assets", BASE_DIR / "app3/templates/assets", BASE_DIR / "app4/templates/assets", BASE_DIR / "app5/templates/assets", BASE_DIR / "app6/templates/assets", ] What I needed was something like this and the collectstatic would have gone to all my apps(1-6) looking for the assets directory. STATICFILES_DIRS = [ 'templates/assets', ] Is there any way to do the same? -

Django and Javascript Uploading Images with Progress Bar

Django channel group_send all messages to one channel in the group
I am trying to make a real time chat web app with Django channel. When I am trying using Postman build multiple WS connections with it. I encountered some weird thing, let's say I have 2 connections to the same server at 8000 port. Then I send a message via group_send, ideally each connection will get 1 message, but it turn out 2 messages are send to the newer connection. Here is my consumer: class RealtimeConsumer(AsyncJsonWebsocketConsumer): async def websocket_connect(self, event): user_id = self.scope['user'] await self.channel_layer.group_add( str(user_id), # use id as the group name self.channel_name ) await self.accept() await self.send_json( { "connectionKey": self.channel_name, "clientId": str(user_id), }, ) async def send_message(self, event): message = event["message"] await self.send_json( { "messages": message, "connectionKey": self.channel_name, }, ) async def websocket_disconnect(self, message): user_id = self.scope['user'] await self.channel_layer.group_discard( str(user_id), # group name self.channel_name ) Send to group func: def send_single_user_msg(channel_name, message): channel_layer = get_channel_layer() async_to_sync(channel_layer.send)( channel_name, { 'type': 'send_message', "text": message, } ) I'm using local redis server as the channel layer. Any idea will be really appreciated. -

Handling SSO between two Django applications
There is two Django-based application under a single platform with different sub-domain. One of the applications is using an OpenSource project. Here databases are different between these applications and both respective user tables. We want to avoid making any major changes to this 2nd application(OSS one) to make sure there is maintainability. The question is how can we have an SSO in a place where the user's signup on the 1st application(our main application), the users should be auto-logged in on the 2nd application too. The 1st application should ideally handle all sign-up/sign-in processes. Both applications support SessionAuthentication. -
