On the `main` branch with the old implementation that table ends up looking like this after the foreign key has been added: ```sql (Pdb) print(fresh_db.schema) CREATE TABLE [dogs] ( [name] TEXT , [breed_id] INTEGER, FOREIGN KEY([breed_id]) REFERENCES [breeds]([rowid]) ); CREATE TABLE [breeds] ( [name] TEXT ); ``` But I think this validation check is failing now: https://github.com/simonw/sqlite-utils/blob/842b61321fc6a9f0bdb913ab138e39d71bf42e00/sqlite_utils/db.py#L875-L884 Here's what the debugger reveals about this code: ```python for fk in foreign_keys: if fk.other_table == name and columns.get(fk.other_column): continue if not any( c for c in self[fk.other_table].columns if c.name == fk.other_column ): raise AlterError( "No such column: {}.{}".format(fk.other_table, fk.other_column) ) ``` ``` (Pdb) fk ForeignKey(table='dogs', column='breed_id', other_table='breeds', other_column='rowid') (Pdb) self[fk.other_table].columns [Column(cid=0, name='name', type='TEXT', notnull=0, default_value=None, is_pk=0)] ``` | { "total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0 } |
