Django - when user submits a form, tables are created, but the connection between the tables is not
i am working on a small project where a customer can go to my website and register phone numbers associated to their name. it is a connection-wise registration (where number1 <--> number2 is one connection), so only two phone numbers are ever registered per session. when viewing a particular phone number (in admins panel, for instance), i want to see the id of the user it belongs to and the id of the connection it is part of. When i view a connection the same way, i want to see who registered that particular connection, and the two phone numbers that were registered in the same session. my problem: all of the foreign keys give a "django.db.utils.IntegrityError: NOT NULL constraint failed" error. I had to set null=True for all of the foreign keys for the customer's data to be submitted at all. the ManyToManyField doesn't give any bugs - but it doesn't limit each Connection to only the two phone numbers registered in the session like it should. and so, this kind of structured connection outlined above isn't made when the data is added. it's like each phone number and each connection and each user becomes its own little island, … -

Nested query in Django ORM
i'm try to remove duplicated row with distinct or annotate then measure count of something.(mysql:8 ,django:2.2) sql select t1.cp_id, count(*) from ( SELECT user_id, product_id, cp_id, count(*) as cnt FROM A where created_at between '2021-07-12' and '2021-07-13' group by user_id, product_id, cp_id ) as t1 group by t1.cp_id my queryset A.objects.filter( created_at__gte='2021-07-12', created_at__lt='2021-07-13' ).values('cp_id', 'user_id', 'product_id').annotate(cnt=Count('cp_id')).values('cp_id').annotate(count=Count('cp_id')) this queryset sql SELECT A.cp_id, COUNT(cp_id`) AS count FROM A WHERE ( created_at >= 2021-07-11 19:30:00 AND created_at < 2021-07-12 19:30:00 AND ) GROUP BY cp_id, created_at ORDER BY created_at ASC I'm confused why Django ignores the order of my commands and executes the last query commands on the original table (not the table where the duplicate data is deleted) Thanks if you have a solution or idea to remove the rows that have the same 'cp_id', 'user_id', 'product_id' (not from the database), then count the number of cp_ids -

If a queryset value is in a list
I'm new to python but am surprised I can't find another post with a similar question to mine. I'm trying to find a way to compare whether a queryset value is inside a list. Take this as an example: account_roles = <QuerySet [<Group: admin>, <Group: customer>]> allowed_roles = ['admin', 'customer', 'supplier', 'observer'] if account_roles in allowed_roles: print('Authorised') Essentially a user has account_roles and I only want to print 'authorised' if a user with an admin or customer role is present. I can only get a comparison working for a single value, but an the entire list of values. Example working for a single value only: if request.user.groups.exists(): group = request.user.groups.all()[0].name if group in allowed_roles: return view_fn(request, *args, **kwargs) Can someone show me how this is done? -

Django Allauth and Salesforce: No_Oauth_State: State was not valid
I am having trouble setting up Salesforce as an auth provider for my Django application using Django Allauth, getting "No_Oauth_State: State was not valid" whenever I try to log in. What I've done: I made a connected app in Salesforce as documented here: https://trailhead.salesforce.com/en/content/learn/projects/build-a-connected-app-for-api-integration/create-a-connected-app I followed the steps outlined in the Salesforce documentation (https://help.salesforce.com/articleView?id=sf.sso_provider_sfdc.htm&type=5) to setup Salesforce as an auth provider. I pasted the consumer key and secret from my connected app into the auth provider settings and copied the callback uri (https://{my_sf_domain}/services/authcallback/salesforce) from my auth provider into the callback uri field of the connected app, as stated in the docs. I configured Salesforce as a provider in my django application as stated in the Allauth docs (https://django-allauth.readthedocs.io/en/latest/providers.html#salesforce) What happens when I try to log in: My application returns a 302 with the Location header set to: https://my.sf.domain/services/authcallback/salesforce/services/oauth2/authorize?client_id={super_secret}&redirect_uri=http://my.django.app.domain/accounts/salesforce/login/callback/&scope=id+openid&response_type=code&state={a_random_string_of_length_12} Salesforce returns a 302 at the uri the above Location header refers to, now with the Location header set to: https://my.sf.domain/_nc_external/identity/sso/ui/AuthorizationError?ErrorCode=No_Oauth_State&ErrorDescription=State+was+not+valid&ProviderId={auth_provider_id} I am unsure how to debug this. Why is the state not valid? Does Salesforce expect the state parameter to be of a certain format? -

Systemd: Messages are logged at the end of script execution
I have Django site that have custom management command that sync data from one system to database every 5 min. In the script for the command there is serveral log messages. When I manually execute the command, everything is working fine and each log message is outputed to stdout/stderr at the time as it should be. No problem here. For running the command every 5min, I setup systemd service and timer and it is working as it should be with one minor thing. All messsages from the script are logged in systemd at the time when the script execution ended, not at the time when they happened. The script is usually running about one minute and log message is outputed sporadically as each subtask in the script has ended. In my case, systemd logged all messages as if they happend at the same time, more precisely at the end of execution. So, log is looking something like this and pay attention on timestamp of messages.

How to save a file using django's File object
I am using Celery to strip the audio from an uploaded video file. I want to save the audio file into my model where the video file is. So this is what I am trying: # model class Video(models.Model): file = models.FileField( validators=[ FileExtensionValidator( allowed_extensions=["mp4", "mov", "flv", "mkv", "avi"] ) ] ) processed_file = models.FileField( validators=[FileExtensionValidator(allowed_extensions=["flac"])], null=True, blank=True, ) # celery task output_audio_file = str(settings.MEDIA_ROOT) + "/" + str(video_obj.pk) + ".flac" ffmpeg.input(video_obj.file.path).output( output_audio_file, **{ "ac": 1, "ar": 16000, "format": "flac", }, ).run() dj_file = File(open(output_audio_file)) video_obj.processed_file = dj_file video_obj.save() This raises the Detected path traversal attempt in '/app/proj/media/49.flac' exception. I also tried with the context manager, with the video_obj.processed_file.save() method. All of which raise TypeError, AttributeError, UnicodeDecodeError and so on.

How to serve Images with Heroku and Django
