Django postgresql model constraint on Charfield
I'm using Django and Postgresql. I've created a CharField in a model, with db_collation of type 'case_insensitive'. I added a unique_together constraint for that field and another field. Seems like the DB identifies '1', '01', '001' as the same, although it's a string (charField), so I'm getting this error message when trying to create different objects with those values - psycopg2.errors.UniqueViolation: duplicate key value violates unique constraint... I don't understand why it identifies them as the same value although it's a string (and it actually saved as '1', '01', '001'... and not all as '1' for example) This is the field in the model: my_identifier = models.CharField(db_collation="case_insensitive", db_index=True, max_length=100, null=True) This is the collation definition: CreateCollation( "case_insensitive", provider="icu", locale="und-u-ks-level2-kn-true", deterministic=False, ) And this is the unique_together definition: unique_together = ('my_identifier', 'container_id') -

Django url in a tag doesnt work because it adds new parameters to the url and doesnt remove unnecessary ones
I googled a lot, but I guess I use the wrong keywords to find the solution: I have this urls.py file: path('site1', views.site1, name='site1'), path('site2/<slug:topic>', views.site2, name='site2'`), I want to add an a-tag to site1. So I would use the following: <a href="{% url 'site1' %}>Link to site1</a> The problem is now that I get an error because the "site1" is added to the end of the current url. So the url looks like this "...site2/site1". What do I have to change to get rid of this error? Thanks in advance! -

Next.js <Link /> navigation causes session logout on Django page
I am working on an application that combines both Next.js and Django (using django-nextjs package). The authentication is managed by Django using session-based authentication. Here's the sequence of events leading to the issue: From the homepage (a Next.js page) where I'm not logged in, I navigate to a Django-based login page. After successfully logging in, I get redirected to a Next.js page. So far, everything works correctly, and I can access user data from the session cookie. As long as I navigate between Next.js pages, the session remains active, and I remain logged in. If I manually enter a URL to a Django page that requires authentication or refresh the page, it recognizes my session, and I remain logged in. However, if I navigate to a Django page using the Next.js <Link /> component, I get logged out instantly. What's puzzling is that the session seems active and recognized across both frameworks until I use the Next.js component to navigate to a Django page. When I do this, Django no longer recognizes my session. What could be causing the session to be lost when navigating via the component? Has anyone faced a similar issue, and how can I fix this? … -
Integrating neural net with Django
I have a sync Django setup, but want to be able to serve neural net predictions. The problem is that running NN prediction requires loading tensorflow library that takes super long to load every time (a few seconds), so this is not an option for every request. I tried instantiating my NN model within a socket server and connecting to it from my django views, but this requires async-ing the entire Django setup. Also not what I want. Is there a way to make these two play nicely together without too much overhead? -

How should I safely add an entry to a database for my Django website without a user entering any data?
I am building a website using Django and Spotipy. When a new user enters the website, they press a button and are redirected to Spotify's login page to authorize the website. I would like to use the get_or_create() method to create a new entry in my database for that Spotify user if one does not already exist. However, the Django documentation says to use get_or_create() only in POST requests. The issue is that after authorizing my website on the Spotify page, you are directed to a callback view where the request method is GET. How would I go about creating a POST request in the callback view so I can safely add the user? Alternatively, is it bad practice to add to a database on a callback page? If so, when and how would you reccommend I add the users information? I considered using get() and create() separately but I imagine anytime create() is used should be in a POST request. After doing some reading, it also seems that it may be possible to use pythons request library, but this seems like it would be unnecessary. -

Static files won't load
I`ve created a new Django project and ran into a problem with static images. So, apparently when i was connecting my css and javascript files with static it worked well, but when i tried to connect images they won't load. here is my settings.py # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/4.2/howto/static-files/ STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_DIRS = ['static'] # Default primary key field type # https://docs.djangoproject.com/en/4.2/ref/settings/#default-auto-field DEFAULT_AUTO_FIELD = 'django.db.models.BigAutoField' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' LOGIN_REDIRECT_URL = '/' urls.py from django.contrib import admin from django.urls import path, include from store import settings urlpatterns = [ path('admin/', admin.site.urls), path('', include('mstore.urls')), ] if settings.DEBUG: from django.conf.urls.static import static urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) here is example of how i display it in template <a href="#" class="item__image"> <picture><source srcset="img/collections/featured/02.webp" type="image/webp"><img src="{% static 'mstore/img/collections/featured/02.png' %}" alt="Lore Walnut"></picture></a> Please, before answering note that i checked the src of the image in browser, and it worked. src of image in browser i copied this link and pasted in browser and got this enter image description here Besides, css and js works great, so i think the problem is in images I tried to run python manage.py collectstatic and it worked perfectly. -
