5 years ago Because MongoDB is not a true database - its just a serialized key-value store (often mistakenly called a document database, even if that's technically incorrect) - and is not ACID complaint like a database must be - since MongoDB is queue-to-write - Mongo DB is a cancer and shouldn't be used anyway, so its not a surprise that its not fully supported.
Setup: USER_ENABLE_EMAIL = True # Disable email authentication USER_ENABLE_USERNAME = False # Enable username authentication USER_REQUIRE_RETYPE_PASSWORD = False # Simplify register form
Description: When trying to create a user, a Mongodb lookup failed.
