How to change the empty_label value in Django's ModelChoiceField?
In Django, I’m using a ModelChoiceField with the empty_label parameter to allow users to unselect a value in a dropdown. Here’s the code: department = forms.ModelChoiceField( queryset=Department.objects.all(), label="Department", required=False, empty_label="------" # Add an empty option ) This works fine, but the default behavior assigns an empty string ("") as the value for the empty_label option. Unfortunately, one of the JavaScript libraries I’m using does not handle empty string values properly. I need to assign a custom value (e.g., -1) for the empty_label option, but I still want to retain its functionality to "unselect" the current object. I’ve tried overriding the choices in the init method, like this: def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['department'].widget.choices = [("-1", "------")] + list( self.fields['department'].queryset.values_list('id', 'name') ) However, when I do this, the functionality doesn’t work as expected — it doesn’t allow the "unselect" option as it does with the empty_label. How can I change the empty_label value (from the empty string) to -1 and still maintain the same behavior of unselecting the option? Thanks in advance for your help! -

Django model FileField with dynamic storage location in migration
I need to store file outside MEDIA_ROOT so I use this approach from django.core.files.storage import FileSystemStorage from django.db import models from myproject.settings import SOME_DIR fs = FileSystemStorage(location=SOME_DIR) class Car(models.Model): photo = models.ImageField(storage=fs) Now, when I makemigrations the result is something like: migrations.AlterField( model_name='car', name='photo', field=models.ImageField(storage=django.core.files.storage.FileSystemStorage(location='C:/temp/documents')), ), The problem is that my local path to SOME_DIR is hardcoded in migration file. So when I push it to production server, where SOME_DIR is /home/xyz/documents, I get warning: Your models in app(s): 'x' have changes that are not yet reflected in a migration, and so won't be applied. Is there any way to suppress the warning or change my code, so it won't use the dynamic location path in migration file? I use Django 4.2, but I think it's the same in all versions. Thanks a lot for help -

Testing an Update a Post function

How to lock read access while creating a model in django?
We notice a lot of trouble within our django application, where we use get_or_create. model, created = SomeModel.objects.get_or_create(user=user, name=name, defaults={...}); if created: get_some_dimensions # SLOW as we call to third party model.dimension_values.set(created_dimensions) # Code here that depends on dimensions being there for the model The problem is that the code above runs twice at the same time. The first time it creates the model, it starts "get_some_dimensions" but doesn't finish that (so not saved) then the second time runs and it sees the model is already there the second run however goes to the "cod here that depends on dimensions" before the first run saves. At step 3 the database gets transformed to an erroneous state. How can I prevent the second run of actually running, lock the database, until the full object is built? -
How to make a dropdown list that can send data to Django (to Models) with Kivymd?
I found a recipe where I could save the results into a variable using the instructions in the KivyMD documentation, but some of the codes shared there did not work in my editor. So, the versions I use are: "python 3.11", "kivymd version 1.2.0" and the MDDropDownItemText module I need to use is not included in kivymd. For this reason, I cannot give special IDs to items and I cannot save the selected values into a variable. What can be done here? My goal was to record whether the user was male or female in the model I created in Django. And I thought I could do this by transferring the result from the drop down list into a variable. I tried following the instructions in the Kivymd documentation, but I encountered the results I mentioned above. KivyMD documentation: text -

Digital Ocean Spaces and Django: Can upload but not open/check if the file exists
I am able to upload to my digital ocean space using my api key from my django app on python 3.10.13. I can see the files as well as open the hyperlinks to them successfully. Images that get uploaded show up on my site as expected. I made all the files public, I've made and re-made my api-keys, I've made my own Media Storage class (I was able to backdoor the functionality by using the response library but that was very slow). I disabled the CDN in case that was interfering. I've re-arranged my folder structure. Tried CORS allow *. Below is the relevant code I am working with. ...

How to configure JWT to work with cookies?
I have a Django application that functions as an API. Currently, it can generate access and refresh JWT tokens and save these tokens as cookies. My problem arises when verifying these tokens in other endpoints. Even though they are being sent correctly, authentication fails. It would be too much information to explain here, but I customized the user class and configured it to use JWT. I appreciate any help, as I'm not sure what to do. When I try to access an endpoint that requires authentication with a token, I receive the message 'Authentication credentials were not provided' and get a 401 error in the response. I believe it could be an issue with the parent class, maybe a method that wasn't overridden but should have been. Here's the repository of the project, which is a small-scale study/test project: https://github.com/MasterTJ123/servant_rpg_back -
How do I GET and POST from different urls to the same class based view in my django project?
I am working on this coursework where I need to create a Django back-end with API routes and templated routes. Within the descriptor, I was given the routes which the project needs to follow. I made a class based view which successfully creates albums. However, the issue which I see is that my implementation GET and POST to /albums/new. Where the descriptor, says I have to GET from /albums/new and POST to /albums to create a new album. I've looked everywhere online to figure out how to implement this and haven't found anything. The lecturer then gave us a tip: The POST of /albums/new/ could be mapped to POST /albums/ using the Django URL dispatcher, where it calls the same class or method for POST. But still had no luck finding anything. Here's my code: views.py album creation view class AlbumCreateView(SuccessMessageMixin, generic.edit.CreateView): form_class = AlbumForm template_name = 'label_music_manager/update_album.html' success_message = _('AlbumCreated') def get_success_url(self): return self.object.get_absolute_url() def dispatch(self, request): if not check_editor(request.user): return redirect('album_list') return super().dispatch(request) url patterns of my view (I created a temporary fix where I can POST to /albums by calling the same view but I don't think that's intended because they wouldn't have separated it) path('albums/', views.AlbumCreateView.as_view(), … -

DRF issue while attempting to inspectdb command error appears: # The error was: ORA-00904: "USER_TABLES"."DEFAULT_COLLATION": invalid identifier
I have an Oracle database version 11.5.10.2. Recently, I study DjangoRestFramework in order to perform own APIs. Firstly, command python manage.py runserver doesn't work due to unable to connect to database. Then I imported oracledb module to settings.py file and added following command: oracledb.init_oracle_client(lib_dir=r'C:\\oracle\\instantclient_23_6') Without client no any connection appears for Oracle database. After that command 'python manage.py runserver' does connect to Oracle DB without errors. Since I don't need to do any changes in database due to many finance records I would upload models structure for my necessary tables only for API use GET HTTP method protocol. So, not at all tables are need to be inspected and moved to models.py file. Thus, for testing I add following command im command prompt: 'python manage.py inspectdb ap.ap_invoices_all' and output text is following: # This is an auto-generated Django model module. # You'll have to do the following manually to clean this up: # \* Rearrange models' order # \* Make sure each model has one field with primary_key=True # \* Make sure each ForeignKey and OneToOneField has `on_delete` set to the desired behavior # \* Remove `managed = False` lines if you wish to allow Django to create, modify, and … -
Google Picker popup window not loading - Django
I am using Google's documentation on the Google Picker at https://developers.google.com/drive/picker/guides/sample and the popup for google drive is not opening when i use this code in django template. I authorize my gmail account but the popup is just not loading. It works fine when i run it via live server on a plain html ( so everything is setup good regarding API_KEY, CLIENT_ID and APP_ID ) but when i run the code inside django, the popup is not there. I tried 3 different (django) projects and the issue persists. Google console is not showing any errors, nothing, it's blank. I do see that APIs return 200 message, so i suspect something about Django is not working well. Cookies or whatever it can be, but i spent past several hours on this and can't find a solution -

When authentication fails I need to store critical data for the login attempt, here is example code: class LoginSerializer(serializers.Serializer): ... def validate(self, data): ... user = authenticate(email=email, password=password) if user is None: failed_login_attempt(email) raise serializers.ValidationError("Invalid credentials") def failed_login_attempt(email): user = User.objects.get(email=email) user.lock_status = "LOCKED" user.save() Device.objects.create(user=user, ip="127.0.0.1", fingerprint="some-fingerprint") Activity.objects.create(user=user, type="failed_login_attempt") Constraints: Raising the ValidationError causes all changes (including updates to user.lock_status, Device and Activity) to be rolled back. This behavior is expected because of the global transaction but I need these changes to persist. I cannot remove ATOMIC_REQUESTS=True as it's crucial for other parts of the application. Goal: I want to ensure that the failed_login_attempt function persists changes even if the ValidationError rolls back the rest of the transaction. What’s the best way to persist those critical changes? What I've tried: Wrapping failed_login_attempt in transaction.atomic() This doesn’t work because they are still part of the outer transaction. Bypassing the ORM and using raw SQL connections.cursor() feels like a hack so I would prefer to avoid it. -
Single 'through' model for multiple m2m fields
I'm trying to extend and refactor some legacy project. I have some set of models which represent "hardware" of some assebled device. Something like : class ComponentA(models.Model) brand = models.CharField() model = models.CharField() category = models.ForeignKey(Category) class Configuration(models.Model): component_a = ForeignKey(ComponentA) component_b = ForeignKey(ComponentB) component_n... class Device(models.Model): configuration = models.ForeignKey(Configuration) The goal is to extent ComponentA...ComponentN with Many2Many field which suppose to contain some extra parts and those parts quantity it consist of. However I found it weird to have through model for each Component model. All of the Component models shoud have a quantity for further statistic/calculations. Is there is some "clean" approach for implementation such a functionality? -
Firebase Push Notifications are not received in Django template but working in other external applications
I have a major problem with Firebase push notifications. I have a Django application with a configured function to send notifications. The function works for sending notifications to a mobile app and a separate React app. However, recently there has been a need for notifications to also reach the same application in Django - meaning the server sends a notification, and the template receives and displays an alert. I configured everything as per the documentation, and notifications are received when they originate from the Firebase console, but those sent from my server are completely ignored and not received. Where should I start looking for the issue? Let me add that sending notifications does not throw any errors. I’m out of ideas on what to do. -
