Prometheus setup for a load balanced Django application
I have a doubt with respect to Prometheus setup for Django applications. If we have a load balancer which redirects to three application servers where the Django applications are running. Which of these setups will work and is optimally correct? Having Prometheus installed in one of the application servers and then having a job for every Django application that needs to be monitored. In this case, should we provide the host application details for all the application servers? Basic Prometheus setup Idea? Will installing Prometheus on any server and mentioning all the Django applications details in the targets entry in prometheus.yml file work? - Do we need to have ssh trust set up in this case when the setup has to be done like this? It will be very helpful if you guys please give some insights on this. If there is any other better way to configure Prometheus, please mention that as well. -

How to get the whole data of the requesting users in Django Friendship
So I am using Django Friendship in order to make the friendship stuff in my web app. Everything is based on the documentation and set up properly. The app works properly but the problem is that I can see only the id of the users. In other words I cannot get access to the whole data of the users. from django.shortcuts import render from django.contrib.auth.models import User from friendship.models import Friend, Follow, Block def AddFriend(request, pk): other_user = User.objects.get(id=pk) Friend.objects.add_friend( request.user, other_user, message='Hi! I would like to add you') return render(request, 'friendshipapp/add_friend.html') def FriendsList(request): friends_list = Friend.objects.friends(request.user) return render(request, 'friendshipapp/friends_list.html', {'friends_list': friends_list}) def RequestsList(request): requests = Friend.objects.unread_requests(user=request.user) users_list = [] for request in requests: requesting_user = User.objects.filter(id=request) users_list.append(requesting_user) return render(request, 'friendshipapp/requests_list.html', {'requesting_users':users_list}) the urls file is set up properly in the requests_list.html I can only see the id of the users. As you can see I tried to loop through the id of the request dispatchers and get access to the user but "request" gives me object of user. How can go around this problem? Thanks in advance -
Django Reactjs object Object
While passing array of fields from reactjs - it is being passed as an object of array while getting the same in django converts it into string of Object Object. So unable to parse the object and get the values of the form fields. Example: We have a html array of fields price[] tags[], when it is passed from Reactjs it is going as addon [ {price:20, tags:"tag1"},{price:25, tags:"tag2"} ,{price:200, tags:"tag3"}] but in django restframework we get as "[ object Object, object Object]" hence unable to access the values. Any help how to solve is highly appreciated. -

'a user with that username already exists' is not in Django UserCreationForm anymore?
I'm studying Django and have come across a question. In several of the Django Youtube Tutorials, I see the Youtuber using the UserCreationForm to create teh signup page and then experimenting with the form to show the viewers about the page. And there comes a time when they signups a user with perhaps a username "test1" and then tries to signup a user with the same username as "test1" and they get the error message 'a user with that username already exists' However, when I've followed these tutorials, I see that there is no error message appearing anymore and it just pops up the original UserCreationForm again in the webpage. Is this error message removed? And I've been looking through the Django Github files and the Django Documentation, but it doesn't mention anything about the username error, so... I'm thinking that it's removed, but I want to be sure. -

How and where to deploy deep learning models, as an Webapp or API ? Need complete suggesion for a beginnier
I have created a deep learning model using TensorFlow/PyTorch, and now I want to deploy it both as an Webapp and API(I guess The webapp will also use the API) To explain, suppose I have a model that detects cars, in images, and returns the co-ordinates, around the bounding box.Or it might might return the image I sent, but after drawing bbox around the cars. What things do I need to learn, better if they are related to python.(I know the webapp part would need JavaScript, but apart from that, for the backend work what do I need to learn)? I don't have clear idea about where to host the model, or how to keep it running, can I do it using Flask or Django? Where can I deploy the model? How much will it cost? Is there any free service for the deployment? I have heard about HeRoku, but not sure if its free tire will cover my requirements. Can you provide any good source(free) , where I can learn machine learning model deployment in detail.(Video or blog, both are welcomed) I believe the question is quite popular for those who want to move from playing with deep learning … -

Django Only non-relations and foreign keys permitted
I'm trying to create a script here that looks at my staff table list that analyzes staffs email addresses and compares it to the login names in the system to assign them to their classrooms, but my script keeps on crashing. What's the goal ? The goal is I have a table called sections, sections are classrooms . Each classroom has a teacher assigned to them. However, in order for the teacher to see the classrooms they are assigned to, im linking this by the users login name which is their email address.

Python, Django: Unique combinations inside a models.py-class?
Good afternoon, I would like to ask, if there's a way to define a unique combination inside my django-model? For example: class Example(models.Model): value_01 = models.Foreignkey(xyz, null=False, blank=False, on_delete=models.CASCADE) value_02 = models.Charfield(max_length=25, null=False, blank=False) Instead of making these two values unique on their own, is it possible to define a unique combination of these two values?

SELECT "some_entity"."id", workspace_events."id", COALESCE(workspace_events."limit", 0) AS "limit" FROM "some_entity" LEFT OUTER JOIN "event" workspace_events ON ( "some_entity"."id" = workspace_events."entity_id" AND workspace_events."entity_type_id" = SOME_ENTITY_CONENT_TYPE_ID AND ) ) ORDER BY "limit" DESC' What am I doing wrong?
