yii - using relation HAS_ONE to get data from the related table to display in list page

Question

I have two tables

big (id, bigs_name, smallid),

small(id, smallguys_name)

therefore two models - big and small

i have used the following relatio

Answer 1

You should like this in big model for relation to small from big,

'has_small'  => array(self::BELONGS_TO, 'small', 'smallid');

Answer 2

The problem is that with a "HAS_ONE" relationship, it is trying to query the SMALL table for SMALLID (has_small.smallid) instead of ID (has_small.id). If BIG really has a "HAS_ONE" relationship with SMALL, you need to put the foreign key for BIG in SMALL (flip flop them), like so:

big (id, bigs_name)

small(id, smallguys_name, bigid)

'has_small'  => array(self::HAS_ONE, 'small', 'bigid')

Otherwise, if you want to keep your DB structure the same, I would use the BELONGS_TO relation like you mentioned in your comment:

'has_small'  => array(self::BELONGS_TO, 'small', 'smallid')
