Django create a models.ManyToMany and models.ForeignKey to the same table
All, I'm trying to configure my Django models.py file to include 2 tables with a ManyToMany and a ForeignKey link between the 2. The current configuration with only one entry works fine: Current models.py file: from django.db import models class CustTeamMembers(models.Model): member_first_name = models.CharField(max_length = 100) member_last_name = models.CharField(max_length = 100) member_email = models.EmailField(unique=True) member_phone = models.CharField(max_length = 25, blank=True) class Meta(object): ordering = ['member_last_name'] def __str__(self): return self.member_first_name + ' ' + self.member_last_name class CustTeamName(models.Model): cust_name = models.CharField(max_length = 100) cust_members = models.ManyToManyField(CustTeamMembers, blank=True) cust_meet = models.CharField(max_length = 40, blank=True) cust_status = models.TextField(blank=True) def __str__(self): return self.cust_name def get_members(self): return ", ".join([str(p) for p in self.cust_members.all()]) I would like to add another field above the "cust_members" entry. The reason for this is I have teams with multiple members and one of them is the lead for the team. I tried the following, but it failed: Alternate models.py file: from django.db import models class CustTeamMembers(models.Model): member_first_name = models.CharField(max_length = 100) member_last_name = models.CharField(max_length = 100) member_email = models.EmailField(unique=True) member_phone = models.CharField(max_length = 25, blank=True) class Meta(object): ordering = ['member_last_name'] def __str__(self): return self.member_first_name + ' ' + self.member_last_name class CustTeamName(models.Model): cust_name = models.CharField(max_length = 100) cust_lead = models.ForeignKey(CustTeamMembers, on_delete=models.CASCADE, blank=True) … -

Is there a way to use a Django registered BaseSetting in a models save function?
I am overriding a model's save function to query Google's Geocoding API for the corresponding latitude/longitude coordinates to an address and save them to the model. I have registered a BaseSetting in Django admin with my API keys, and would like to access this registered setting inside my models.py to avoid hard-coding an API key. Handling it in the view is not an option given I would like to minimize the number of API calls. Here's some demo code: class DropoffLocationPage(models.Model): templates = "locations/dropoff_location_page.html" dropoff_address = models.CharField(max_length=40, blank=False, null=False) dropoff_city = models.CharField(max_length=40, blank=False, null=False) dropoff_state = models.CharField(max_length=2, blank=False, null=False) dropoff_zip = models.CharField(max_length=5, blank=False, null=False) dropoff_unit_number = models.CharField(max_length=10, blank=True) dropoff_latitude = models.CharField(max_length=25, blank=True) dropoff_longitude = models.CharField(max_length=25, blank=True) def get_coordinates(address): .... return response['results'][0]['geometry']['location'] def save(self, *args, **kwargs): address = str(self) location = get_coordinates(address) self.dropoff_latitude = location['lat'] self.dropoff_longitude = location['lng'] super(DropoffLocationPage, self).save() def __str__(self): return (self.dropoff_address + " " + self.dropoff_city + ", " + self.dropoff_state + " " + self.dropoff_zip + " " + self.dropoff_unit_number) @register_setting class GoogleAPISetting(BaseSetting): maps_api_key = models.CharField( max_length=255, help_text="Your Google Maps API Key" ) -
How to extend query table for reviews of people I follow with user details
I'm trying to create a Django project, and currently I have three models in use: the standard Django User, Review and Follow, given below: class Review(models.Model): author = models.ForeignKey(User, on_delete=models.CASCADE) text_content = models.TextField(max_length=300) movie_rating = models.IntegerField() class Follow(models.Model): following = models.ForeignKey(User, on_delete=models.CASCADE, related_name="following") follower = models.ForeignKey(User, on_delete=models.CASCADE, related_name="follower") What I want to get as a result is given user as a input, get all the reviews of people I follow. I used the following command Review.objects.filter(author__following__follower=user), and it gives me the user_id, text_content and movie_rating, but I'm not sure how to extend this table to add some things from the User model, such as first_name and last_name. -

How can I optimize the speed of this algorithm? Django and Javascript
I am new to Javascript and have decent experience with Django. I built a charting platform for my company to track metrics -- it started as a hobby project to learn Javascript but evolved into something more. The site loads and displays data correctly, but it is unbelievably slow on mobile. All of the calculations are being done on the client-side is JS. There are a lot of metrics to calculate, so the thought process was "Send the client all the Django queries in Object format, and process them there in order to not slow down the server." I also did not want to have a huge block of code processing each metric on the server (am I wrong to do this?). Some questions here: In general, where should I process the data, server-side or client-side? How can I optimize this code? I run 3 queries, and I need to find the number of hits for each metric on every day (page views, opt-ins, and scheduled calls). For example, I want to display a chart showing the number of page views over a month period with the x-axis being the date, and the y-axis being count. In order to do … -
Sending message and notification using Django channels
I am trying to implement a messaging system with live notification so that when a user is chatting with userA and userB messages the user it will update the chat messages live and it will update the user's contact list. I have two consumers, one is ChatConsumer, and another one is the UserChatNotificationConsumer which the latter is a connection for each user and server to a notification to them. And every user channel has a unique id (channel name). inside my ChatConsumer, I have a new_message() function which sends a new message from one user to another user in a private chat. After creating a message object in the new_message() function, I have two methods one which sends the message and another which sends the notification: def new_message(self, data): #create the message and other stuff. await self.send_chat_message_notification_user2(content) await self.send_chat_message(content) And my method for sending a notification to user is: async def send_chat_message_notification_user2(self, message): layer = get_channel_layer() await selg.channel_layer.group_send( self.user2_notification_layer, { 'type':'chat_message', 'message':message } ) Which self.user2_notification_layer is a string id of the second user in the chat notification channel. My issue is that the sockets are being connected successfully and I can see the CONNECT and HANDSHAKE process. however, after … -

I was researching last night and it is a common problem and many differnt implementations. Most common that I have seen is with student, teacher, admin.
