DigitalOcean spaces with django
I have a Learning Management System frontend written in React Js and backend written in django. Users can upload PDF files and image files from the frontend. PDF files are lessons and image files going to be user profile pictures, Subject pictures and course pictures I've configured Digitalocean spaces with the current setup. All the static files, images and pdf files are saving in the object storage. But I need to save pdf files and static files inside the object stiarage and Images inside backend servers.

Python Django website not showing on Ubuntu like on Windows
I run into a problem without understanding where it could come from. I have the same website in Django 3.0.8 under environment which works on one side on a PC with windows 10: preview on Windows On the other side, on an old PC with Xubuntu 20.04: preview on Xubuntu Everything is the same: code, files, environments, version of python (3.8). However, the Xubuntu version doesn't perform well as you can see. Do you have any idea what could be blocking? I have the impression that Bootstrap and FontAwesomeIcon are not working correctly. -

Nuxt auth with cookies with DRF
I'm trying to implement authentication on my frontend (which is written in NuxtJS) using cookies as opposed to local storage. I'm using the nuxt-auth package, with the following configuration:- auth: { strategies: { cookie: { token: { required: false, type: false, }, user: { property: false, }, endpoints: { login: { url: '/auth/token/login/', }, user: { url: '/auth/users/me/', method: 'get', }, logout: { url: '/auth/token/logout', }, }, }, local: false, }, } My backend is django with rest framework and djoser with the following config:- DJOSER = { 'CREATE_SESSION_ON_LOGIN': True } REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': ( 'rest_framework.authentication.SessionAuthentication' ), } When I call the auth login method in my frontend, like this:- this.$auth.loginWith('cookie', { data: this.login, }) it all works as expected. The frontend calls /auth/token/login. The backend authenticates the user and sets the cookie in the browser. The frontend calls /auth/users/me which returns the user data and the frontend sets loggedIn to true. But when the user tries to logout in the frontend, the POST request fails because the CSRF token is not set. HTTP 403: CSRF Failed: CSRF token missing or incorrect. I've tried all sorts of other ways to set this stuff up and none of them seem … -
How to set '%' mark in as_sql query (custom Lookup) in Django?
I try to select phone numbers from DB ignoring (, ) , - symbols and allowing to search by substring I have a custom lookup from django.db.models import Lookup from django.db.models import Field class ContainsPhoneNo(Lookup): lookup_name = 'contains_phone_no' def as_sql(self, compiler, connection): lhs, lhs_params = self.process_lhs(compiler, connection) rhs, rhs_params = self.process_rhs(compiler, connection) print(lhs_params, rhs_params) params = lhs_params + rhs_params return "REPLACE(REPLACE(REPLACE(%s, '(', ''), ')', ''), '-', '') ILIKE %s" % ( lhs, rhs), params Field.register_lookup(ContainsPhoneNo) So right now, for example, if I filter by 2345, I can get (23)-45, 2-3-45, etc numbers. But I want to get also 123456. So my query should be "REPLACE(REPLACE(REPLACE(%s, '(', ''), ')', ''), '-', '') ILIKE %%s%" But I don't know how to set % symbols before and after second %s. Django don't allow to set % as is inside query string (I also tried '%'+str(rhs)+'%' way). So how can I do that? -
Django - Add custom field in django admin get_queryset method with multiple levels of prefetch_related
I have the following models. There are Stops in Cities. There are Connections between Stops. MODEL.PY class City(models.Model): pass class Stop(models.Model): city = models.ForeignKey(City, related_name='stops') class Connection(models.Model): origin = models.ForeignKey(Stop, related_name='origin_connections') destination = models.ForeignKey(Stop, related_name='destination_connections') In Django Admin view of City, I want to have clickable custom field showing the number of Connections with links to those Connections.

How can I use multiple inheritance to compose Django forms?
I have lots of forms which contain the same non-model field. For the sake of this example, let's call the field author. This is not a field of any model, just a field that I want to appear in each form. Here is a working example of my current code: from django import forms from . import models class BlogForm(forms.Form): author = forms.CharField() class Meta: model = models.Blog fields = ["author"] class BookForm(forms.Form): author = forms.CharField() class Meta: model = models.Book fields = ["author"] So, naturally, I thought I could use Python inheritance and create a reusable "mixin" class that contains this field. However, it seems that this is not possible. For some reason, I can't get the following to work: from django import forms from . import models class AuthorMixin: author = forms.CharField() class BookForm(AuthorMixin, forms.Form): class Meta: model = models.Book fields = ["author"] This is the error I'm getting: django.core.exceptions.FieldError: Unknown field(s) (description) specified for Book How can I use multiple inheritance to compose Django forms? -

Can this Django queryset loop be optemize?
I need to replace an index value in a pandas data-frame, my solution involves looping through the queryset and replacing the values 1 by 1 before converting into a list for pandas.

Django - Generic OneToOneField to enable select_related() functionality
I have the following models: class A(Model): ... class B(Model): ... class C(Model): ... class Generic(Model): genericable_id = PositiveIntegerField() genericable_type = CharField() # One of A, B, C ... For which the data look like this: Table A: id, other fields 1, ... 2, ... Table B: id, other fields 1, ... 2, ... Table C: id, other fields 1, ... 2, ... Table D: id, genericable_id, genericable_type, other fields 1, 1, 'A', ... 2, 2, 'A', ... 3, 1, 'B', ... 4, 2, 'B', ... 5, 1, 'C', ... 6, 2, 'C', ...

I was wondering whether it is possible to somehow define that relationship in Django so I can do for example: qs = A.objects.select_related().all() # all generic objects for A retrieved … -
form registers as valid but does not update
This is a very weird phenomenon. Why is it that even though the form is valid, the values are not updated? It works if i do it in django admin though. I am not even receiving any errors.

Python threading lifecycle
I am developing a Django project where after discarding the use of celery for its complexity, I have implemented python threading directly through the Thread class. The purpose is very simple tasks that do not need a control if they have been carried out, such as sending push messages to devices (with a very low load, in the order of about 20 messages per hour). However I have been looking for multiple information about the Thread life cycle in python and I can come up with a conclusion about it. Is it necessary to manually close each Thread launched or does the process end when the run function completes? Not being necessary to control the correct execution of the operation, what advantages does the use of celery have over this option with the purpose and workload mentioned?
