gunicorn not picking up changes in django code even after restarting
I have this web application that I built with django, and deployed with gunicorn and nginx on GCP Compute Engine Instance. I serve the static files with nginx. For nginx, whenever I push new code to the server, run collectstatic, and restart nginx, I see the static file update working fine. The problem begins with the server code. Whenever I push code to my django views, or run migrations, or push code to my html file, and restart gunicorn, I don't see the changes right away. It takes about a full day for the change to take effect. I have tried reloading daemon, restarting gunicorn, restarting nginx but the issue persists For the nginx, here is my location settings on nginx configuration location /static/ { alias /home/user/app/backend/static/; } location / { proxy_pass http://127.0.0.1:8000; } There you can see that I serve the static file using nginx, then pass every other request to the app. Then when I push code to my github, pull it into the app, and run python3 manage.py collectstatic Then restart nginx with sudo systemctl restart nginx Everything works great. Now for the part that I think the problem comes from. If I make a change to … -
Unable to run the server after export on another computer (migrations worked)
I am lost with what is probably a very simple issue configuring a django / mysql project. I have a working project on a computer A, which I just want to be able to use with a computer B. On computer A, I have an Eclipse project, using Pydev and Django, a local virtual environnement, and a local database running with Mysql. What I have done: I exported the virtual environnement (including django) and created the same one on computer B; I used Gitlab in order to get all the files with the code ; I installed Mysql, and created a database with the same name, and a user with the same informations (id / pwd). The migrations went well, the tables are created like I expected. However, I cannot find a way to run the server. When I try, I get multiple errors saying one (and only one) of the Apps is not loaded yet, then another error, which seems to be related to the database. Here are some of the messages: Traceback (most recent call last): File "/home/francois/snap/eclipse/67/amd64/plugins/org.python.pydev.core_10.2.1.202307021217/pysrc/_pydev_runfiles/pydev_runfiles.py", line 460, in __get_module_from_str mod = __import__(modname) File "/home/francois/eclipse-workspace/iou/members/forms.py", line 2, in <module> from django.contrib.auth.forms import UserCreationForm, AuthenticationForm, UsernameField File … -
With FileField, opening file before inserting database
I have models, serializer and viewsets with FileField class Drawing(SafeDeleteModel): drawing = f.FileField(upload_to='uploads/') class DrawingSerializer(ModelSerializer): drawing = serializers.FileField() class DrawingViewSet(viewsets.ModelViewSet): queryset = m.Drawing.objects.all() serializer_class = s.DrawingSerializer def create(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) print("serializer request:",request.data['drawing']) # this is myfile.pdf self.perform_create(serializer) print("serializer seliarizer",serializer.data['drawing']) # myfile_ccA3TjY.pdf try: doc = fitz.open(file_path) # open to check if it is correct pdf except; raise Exception("file is not valid pdf") When uploading file,request.data['drawing'] is myfile.pdf, serializer.data['drawing'] is real name myfile_ccA3TjY.pdf. ( when there is the same name file) So for opening file with fitz, I need to know the real name myfile_ccA3TjY.pdf. I have to do self.perform_create to know the real file name, and it creates the row. However I want to cancel inserting to database when file is not valid pdf. With this code database inserting is executed even file is not correct pdf. Is there any way to open the file without calling self.perform_create? -
My web application dont load styles files when in production
My project in Django https://github.com/alex-martins2305/ToDo4 works very fine in production, bootstrap, css, everything loads perfect. But in deploy to render.com the css file dont load. I already checked: In github the files are avaliable in static/css/styles.css; run collectstatic; cleaned browser data; tryed in mozzila and chrome (desktop and mobile); In chrome i can see in inspection/network the reason to not apply the style file: Refused to apply style from 'https://todo4-hk3r.onrender.com/static/ccs/styles.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. -

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. -
