```javascript // Defining Model LikesCut.hasOne('target', Cuts, {reverse: 'likes', field: 'targetId', mapsTo: 'target_id', required: true}) // CASE 1 : ER_BAD_FIELD_ERROR: Unknown column 't1.targetId' in 'on clause' LikesCut.findByTarget({}).runAsync() // CASE 2 : ER_BAD_FIELD_ERROR: Unknown column 't2.targetId' in 'on clause' Cuts.findByLikes({}).runAsync() ``` it seems to tying `join` with wrong column name. is there something wrong in my codes or isn't it prepared yet?
