I'm making an Learning Management System.

How to get a specific record in a lookup table in Django
I'm building a Django app that manages client data. I store phone numbers, email addresses, addresses, etc., in lookup tables. I would like to create a queryset that returns the primary numbers for all clients. Here is an abbreviated version of the client table: id last first etc 100426 Smith John etc 114988 Johnson Thomas etc An example of the phones table: id client_id type_id is_primary number 1 100426 1 t 427-567-8382 2 100426 2 f 427-567-7789 3 114988 1 t 914-223-4597 And finally, the phone_type table: id type 1 mobile 2 home 3 office 4 condo An extract of the client model: class Client(models.Model): id = models.IntegerField(primary_key=True) last = models.CharField(max_length=32) first = models.CharField(max_length=32) phone = models.ForeignKey( Phone, on_delete=models.PROTECT, blank=False, null=False ) The phone model: class Phone(models.Model): id = models.IntegerField(primary_key=True) client_id = models.IntegerField type_id = models.ForeignKey( PhoneType, on_delete=models.PROTECT, blank=False, null=False) is_primary = models.BooleanField country_code = models.CharField(max_length=5) phone_number = models.CharField(max_length=16) And the phone_type: class PhoneType(models.Model): id = models.SmallIntegerField(primary_key=True) type = models.CharField(max_length=16, blank=False, null=False) My ClientListView: class ClientListView(ListView): model = Client template_name = 'client/client_list.html' context_object_name = 'clients' def get_queryset(self): return Client.objects.order_by('-id').filter(status_id=3).select_related(Phone) The get_queryset function is a placeholder for now.

Django - Disable Cache key warnings
I am currently designing a Django application and set up a database cache, increased the key size to 500 characters, however I constantly receive this warning: CacheKeyWarning: Cache key will cause errors if used with memcached: key_text (longer than 250) Reading through the documentation here: https://docs.djangoproject.com/en/3.2/topics/cache/ If you are using a production backend that can accept a wider range of keys (a custom backend, or one of the non-memcached built-in backends), and want to use this wider range without warnings, you can silence CacheKeyWarning with this code in the management module of one of your INSTALLED_APPS. I've created management folder in my app (tried various places) and added the code required inside it as management.py but it's not working. Has anyone managed to silence these warnings and can please share where they added it? Thanks -

Django returns blank QuerySet despite names matching
I have a model Employee, where one of the fields is manager, which is a ForeignKey to another model called Manager. I am checking whether a manager value I'm passing through the previous page matches with an object of Employee that has the same manager, and I want to get only those objects where the manager matches. However, despite me having employees that have different managers each, I try filtering using Employee.objects.get(manager=manager) or Employee.objects.filter(manager=manager), and neither returns anything. filter returns a blank queryset and get says Employee matching query does not exist. despite it clearly matching.

Allauth - get SocialAccount.id after successful login/connect/signup
After the user connects their social account (which can be any of Google, Microsoft and even custom providers) and is redirected to /some/redirect/url, I need to get the ID of the account (SocialAccount model). A very simple example would be: user clicks on accounts/google/login/?process=connect&next=/some/redirect/url After successful connection (no matter if already exists or not), user is redirected to /some/redirect/url The page says "Your newly connected SocialAccount.id is 45" I could theoretically get all SocialAccount objects of this user and return the newest one but I want this to work also when the user just doesn't realize they already connected their account. How can I do that? EDIT: I'm also open to using cookies as a messenger for this ID. -

Django: ERROR (EXTERNAL IP): Invalid HTTP_HOST header ... - Correct host but spam queries?
Sometimes I get a wave of errors like this: [Django] ERROR (EXTERNAL IP): Invalid HTTP_HOST header: 'app.mysite.com'. You may need to add 'app.mysite.com' to ALLOWED_HOSTS. The thing is, app.mysite.com is the correct host, and it definitely is already in allowed host. However, the requests that are getting blocked are spam, sending: Post requests to '/uncensored' Requests to '/query?dns=DUIBAAA...' (long string of letters) Requests to '/doh/family-filter?dns=....' (long string) All have CONTENT_TYPE = 'application/dns-message' It makes sense that the queries are blocked, but it doesn't make sense that it's an invalid HTTP_HOST header error.

Export selected rows in CSV with django-tables2
I'm using django-tables2 to create a table.

My question is how can I use that to export ONLY the selected rows in CSV? I want to avoid using JS, as this way I'm afraid I lose the functionality that comes with TableExport. thanks in advance. -

With an existing Django site, can I write a script that returns raw output, kind of like and API but simpler?
I have a very simple django site running on pythonanywhere.com; I'd like now add on a script that does something not directly related to the website. Specifically I'd like to run a script that takes a URL such as www.mysite.com/GetLatLong/V95AE16 In this case the V95AE16 is a postcode The url would execute the script GetLatLong.py using V95AE19 as input and then return raw data in the format 52.46723, -8.23564 This is to be used by a different application (nothing to do with python) which will just use my script like an API, just simpler, no CRUD, just giving a single value and getting some values in return Many thanks / Colm -
