class crate_anon.crateweb.consent.storage.CustomFileSystemStorage(*args, **kwargs)[source]

Subclasses django.core.files.storage.FileSystemStorage to improve URL processing, as below.

Notes:

In order to use reverse(), config/urls.py can’t import views that import models that use this… so use string, not actual Python object, references for urls.py.

However, in urls.py, we also need things like mgr_admin_site.urls, and consent/admin.py also imports models (which imports storage). Problem. Specifically, a problem for making the URLs non-absolute for non-root hosting.

So we use get_script_prefix() instead?

But that isn’t set at the time this is loaded, so that’s no good either. The only other way to handle this would be to override the view form, or offer the private storage via Apache (but the latter would prevent proper security, so that’s a no-no).

Therefore, let’s subclass django.core.files.storage.FileSystemStorage, so we can make the change at runtime.

url(name: str) → str[source]

Returns the URL for a given filename.
