Bug different SQL Queries generated by Django when requested from different application
I have a question related to Django Application and Django REST Framework. I have posted GET request to same API from 3 different device, ReactNative with axios, Browser, and Postman. All these 3 devices trigger different number of queries to database. enter image description here I checked the SQL query detail, and here is the result for each devices. enter image description here Please share some insight on why is this happening, or any other details that I need to provide to find the reason or fix the issue -
Django makemigrations error: "__init__() got an unexpected keywork argument 'max_Length'
I am trying to make migrations to a new app 'users' and keep receiving the error: "TypeError: Field.init() got an unexpected keyword argument 'max_Length'" I previously encountered this error when making migrations on my last app and was able to find the issue on a stackoverflow post which I can't seem to relocate. I know that max_Length is valid because it worked last time but can't seem to remember what I did to make the migrations work. My settings.py files with the users app activated My models.py in my users app: I've spent a lot of time trying to figure out what I am missing but can't seem to get it. Python manage.py makemigrations worked last time with the projects app having the same 'max_Length' constraints. Any ideas on how I can fix this? Thanks in advance -

aws ec2 and gcp e2 instances constantly become unresponsive
I've deployed a Django app on AWS-ec2-micro instance and a React app on GCP-e2-micro instance before, but I encountered almost the exact same problem: Server will randomly become unresponsive and unreachable while doing some heavy I/O operations. It happens almost all the time if I try to install some large packages such as tesseract, but it sometimes freezes even when I'm just trying to run a react app using npm start. I've looked at the monitoring and they all have one thing in common: super high CPU usage. Especially after the server becomes unreachable, the CPU meters continue to rise. AWS-ec2 usually will reach almost 100% while GCP-e2 instance will reach beyond 100% to something like 140%. At a certain time, the CPU usage will become stabilized at about 50%, but the server is still unreachable using SSH. The server sometimes recovers itself after hours of being unreachable, but usually, it ends up having to force stop and restart the server. This will cause the public ipv4 to change which I really don't like, so I want to find out why my server is constantly unresponsive. Here is what I've installed on my server: ssh-server vscode-server And then on GCP-e2, … -

[Django][DRF] How to get UNORDERED queryset using .filter?
first of all, I'm not a native at ENG so plz be patient my ENG skills or give me some advice. I'm writing API creating a post by using drf serializer. And I've been facing a problem with "the order of tags adding to the post". post and tag models are connected through M2M field which means, let's say I add tags a, b, and c on a post. The logic I use as follows. # class Serializer # def create(instance): # instance : specific post instance tags = ['t', 'a', 'g', 's'] Tag.objects.bulk_create([Tag(name = tag) for tag in tags]) instance.add.tags(*[tag for tag in Tag.objects.filter(name__in = tags)]) run this at first. tags are added in this order TagQuerySet[Tag<'t'>, Tag<'a'>, Tag<'g'>, Tag<'s'>] And my API takes the other create request that include the tags of the existing like, tags = ['g', 'a', 's'] django add in the sorted order, not in the order I want like, # tags new created instance TagQuerySet[Tag<'a'>, Tag<'g'>, Tag<'s'>] I know the method that adding tags following my list order using for loop for tag in tags: instance.tags.add(Tag.objects.get(name=tag)) but it's not efficient. So my question is how to get queryset using .filter following my list order. … -

Get the Auto Field id of the newly created record in the model, provided the description of the fields in forms.py [closed]
I'm just starting to learn django, please tell me: I need to get the id of the newly created record in the model, the problem is that I do not know how to declare it. Since the record id is Auto Field, the id is not passed to forms.py , and is created/remains in the database after the record is created. If I didn't use the functionality forms.py , I would be able to get this id, similar to the example from the documentation (https://docs.djangoproject.com/en/dev/ref/models/instances/?from=olddocs#auto-incrementing-primary-keys): Auto-incrementing primary keys If a model has an AutoField — an auto-incrementing primary key — then that auto-incremented value will be calculated and saved as an attribute on your object the first time you call save(): b2 = Blog(name='Cheddar Talk', tagline='Thoughts on cheese.') b2.id # Returns None, because b2 doesn't have an ID yet. b2.save() b2.id # Returns the ID of your new object. There’s no way to tell what the value of an ID will be before you call save(), because that value is calculated by your database, not by Django. For convenience, each model has an AutoField named id by default unless you explicitly specify primary_key=True on a field in your model. See … -

User permission cache in Django-Webtest
My project uses a custom authentication backend for managing user permissions, leaving the authentication itself intact (to be handled by Django). The backend works fine by itself but started failing in tests, built using Django WebTest. After picking around, I discovered that the culprit is the injection by DWT of another auth backend into the first position in settings.AUTHENTICATION_BACKENDS. My backend directly extends Django’s ModelBackend while DWT’s own backend is based off RemoteUserBackend, which in the end is also an extension of ModelBackend. This bit is important, because while DWT does not define a has_perm method, it is present on its backend nevertheless. The django.contrib.auth.backends.ModelBackend’s get_all_permissions() caches the permissions on the user object in question, when performing a has_perm test: if not hasattr(user_obj, '_perm_cache'): user_obj._perm_cache = { *self.get_user_permissions(user_obj), *self.get_group_permissions(user_obj), } return user_obj._perm_cache Since DWT’s backend comes first in tests, the cache is populated and would not contain the permissions set by my backend, ultimately causing the has_perm test to fail. Ref the code snippet from within Django: def _user_has_perm(user, perm, obj): """ A backend can raise `PermissionDenied` to short-circuit permission checking. """ for backend in auth.get_backends(): if not hasattr(backend, 'has_perm'): continue try: if backend.has_perm(user, perm, obj): return True except PermissionDenied: … -

Render images with Vue.js and Django
I am currently building a LMS where the admin can upload multiple images to a lesson. I am having some issues rendering these images with vue.js. In my models.py I have a Photos model which uses a foreignkey to the lesson model. In the admin I can add the images but in the html the images appear as an empty list with the photo id number e.g [4] In the console I can see the photos array with the length of photos in the lesson object but I cant seem to attach it to the frontend.
