I’m trying to create a relation that will allow me to fetch the current “Versions.label” based on each widgets per project. The below relation generates the correct SQL statement, but I can not fetch the variable “Versions.label” because the “SELECT” portion of the generated query do not know about the joined table. Please help so that I can do model->label (where label corresponds to Versions.label).
public function relations()
{
return array
(
'widget_versions'=>array(self::MANY_MANY, 'Widgets', 'ProjectWidgets(project_id, widget_id)',
'join'=>'LEFT OUTER JOIN `Versions` ON (`Versions`.`id`=widget_version_id)')
);
}
SELECT `t`.`id` AS `t0_c0`, `t`.`title` AS `t0_c1`, `t`.`url`
AS `t0_c2`, `t`.`svn_repository` AS `t0_c3`, `t`.`dt_create` AS `t0_c4`,
`widget_versions`.`id` AS `t1_c0`, `widget_versions`.`version_master_id` AS
`t1_c1`, `widget_versions`.`title` AS `t1_c2`,
`widget_versions`.`view_alias` AS `t1_c3`, `widget_versions`.`dt_create` AS
`t1_c4`, `widget_versions`.`id` AS `t1_c0`
FROM `Projects` `t`
LEFT OUTER JOIN `ProjectWidgets` `widget_versions_widget_versions` ON
(`t`.`id`=`widget_versions_widget_versions`.`project_id`) LEFT OUTER JOIN
`Widgets` `widget_versions` ON
(`widget_versions`.`id`=`widget_versions_widget_versions`.`widget_id`) LEFT
OUTER JOIN `Versions` ON (`Versions`.`id`=widget_version_id) WHERE
(`t`.`id`=7)
I just need it to look like this:
SELECT `t`.`id` AS `t0_c0`, `t`.`title` AS `t0_c1`, `t`.`url`
AS `t0_c2`, `t`.`svn_repository` AS `t0_c3`, `t`.`dt_create` AS `t0_c4`,
`widget_versions`.`id` AS `t1_c0`, `widget_versions`.`version_master_id` AS
`t1_c1`, `widget_versions`.`title` AS `t1_c2`,
`widget_versions`.`view_alias` AS `t1_c3`, `widget_versions`.`dt_create` AS
`t1_c4`, `widget_versions`.`id` AS `t1_c0`,
`Versions`.`label` AS `versions_label` FROM `Projects` `t`
LEFT OUTER JOIN `ProjectWidgets` `widget_versions_widget_versions` ON
(`t`.`id`=`widget_versions_widget_versions`.`project_id`) LEFT OUTER JOIN
`Widgets` `widget_versions` ON
(`widget_versions`.`id`=`widget_versions_widget_versions`.`widget_id`) LEFT
OUTER JOIN `Versions` ON (`Versions`.`id`=widget_version_id) WHERE
(`t`.`id`=7)
