Find all the documents with Optional[Link[...]] = None

[chabErch]

Hi ❤️!

I have the department model:

class Department(Document):
    name: str
    parent: Optional[Link['Department']] = None

And I want to get all the documents with parent == None:

departments = await Department.find(Department.parent == None, fetch_links=True).to_list()

And I get an error:

...
departments = await Department.find(Department.parent == None, fetch_links=True).to_list()
  File "/usr/local/lib/python3.9/site-packages/beanie/odm/queries/cursor.py", line 69, in to_list
    cursor = self.motor_cursor
  File "/usr/local/lib/python3.9/site-packages/beanie/odm/queries/find.py", line 595, in motor_cursor
    self.find_expressions[i] = convert_ids(
  File "/usr/local/lib/python3.9/site-packages/beanie/odm/utils/relations.py", line 61, in convert_ids
    and k.split(".")[1] == "id"

Do I miss something?

Hi, do you have any news? I can duplicate it as an issue if needed

Hi! Ah, yes. It is better to make an Issue. I fix bugs there first.
