Two SQLAlchemy Warnings while running tests

[PonteIneptique]

• Warning 1

tests/db_fixtures/wauchier.py:9: SAWarning: relationship 'ChangeRecord.word_token' will copy column word_token.id to column change_record.word_token_id, which conflicts with relationship(s): 'WordToken._changes' (copies word_token.id to change_record.word_token_id). If this is not the intention, consider if these relationships should be linked with back_populates, or if viewonly=True should be applied to one or more if they are read-only. For the less common case that foreign key constraints are partially overlapping, the orm.foreign() annotation can be used to isolate the columns that should be written towards. The 'overlaps' parameter may be used to remove this warning.
Column(heading="Lemma"),

• Warning 2

app/models/control_lists.py:72: SAWarning: SELECT statement has a cartesian product between FROM element(s) "control_lists" and FROM element "control_lists_user". Apply join condition(s) between each element to resolve.
ControlListsUser.control_lists_id == corpus.control_lists_id
