Can't get Django-CMS to work with Apache and mod_wsgi
I am trying to get django-cms to run with apache wsgi. I am using Python 3.12 and the latest version of all software (a fresh bare metal install of ubuntu 24.04). Django-cms runs with runserver.

How to revert migrations when there are multiple leaf nodes?
manage.py showmigrations shows me a list like ... [X] 0240_employer_data (A) [X] 0241_person_metadata (B) [ ] 0242_delete_capability_delete_collection (C) [X] 0242_personemployer_employerworkplace (D) [X] 0243_personemployer_employed_personemployer_stage (E) [X] 0244_remove_employerworkplace_and_more (F) 0242_delete_capability_delete_collection arrived after doing a git pull and rebase. My local branch stuff that I had been working with is 0242_personempl..0244. I believe the graph looks like | A | B / \ D C | E | F Because all my migrations are just in development, I'm trying to undo them to reach the same state that the main branch is at, then make them again. I thought I could manage.py migrate myapp C delete my local D, E, F migration files files manage.py makemigrations manage.py migrate But both manage.py migrate myapp C and manage.py migrate myapp B throw the same error: CommandError: Conflicting migrations detected; multiple leaf nodes in the migration graph: (0242_delete_capability_delete_collection, 0244_remove_employerworkplace_and_more in myapp). It looks like I cannot even revert migrations while the migration graph is in this state. What can I do to just reset my local branch's migrations and compatibilise with the main branch before building my local branch's needed migrations again? "Rebasing" the migrations in a way? -

django, how to use subquery values into outer query
I have a query that uses the values from a subquery. While I'm able to write the subquery in django, I can't write the main query. Here's a little example (the schema is department <-- person <-- device --> model): SELECT department.id, AVG(subquery.typeofdevices_count) AS avg_typeofdevice_count_per_department FROM department INNER JOIN person ON (department.id = person.department_id) INNER JOIN device ON (person.id = device.person_id) INNER JOIN ( SELECT model.id AS id, count(DISTINCT device.location_id) filter (WHERE device.type = 'something') AS typeofdevices_count, FROM model LEFT OUTER JOIN device ON (model.id = device.model_id) WHERE ('some-conditions...') GROUP BY model.id, ) AS subquery ON (subquery.id = device.model_id) As you can see the outer query uses the inner value typeofdevices_count while joining with the subquery id. About the inner query is quite simple: subquery = Model.objects.annotate(typeofdevices_count= Count('device__location_id', filter=Q(device__type='something'), distinct=True ) ).filter('some-conditions...').values('id', 'typeofdevices_count') What about the main query? I tried with the following: Department.objects.annotate(avg_typeofdevice_count_per_department= Avg('persons__devices__model__typeofdevices_count', filter=Q(persons__devices__model__in=subquery) ) ).values('id', 'avg_typeofdevice_count_per_department') But I got this error, it seems it doesn't recognize the subquery annotation typeofdevices_count FieldError: Cannot resolve keyword 'typeofdevices_count' into field. Choices are:... Can you help me? -
wsgi process not loading the correct python environment

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 -

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. ... CREDS ABOVE AWS_S3_ENDPOINT_URL = config["remote_storage"]["AWS_S3_ENDPOINT_URL"] AWS_LOCATION = 'media' AWS_QUERYSTRING_AUTH = False # Set to False if files are public MEDIA_URL = f"https://{AWS_S3_ENDPOINT_URL}/{AWS_LOCATION}/" DEFAULT_FILE_STORAGE = 'spyglass.storage_backends.MediaStorage' class MediaStorage(S3Boto3Storage): location = 'media' default_acl = 'public-read' querystring_auth = False def exists(self, name): print(f"Checking if {self.url(name)} exists") return super().exists(name) The link that is printed works without a problem however the exists returns False. I've been scratching my head for 2 days and could really use a nudge in the right direction as this is all new to me. -
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(), …
