Re: Pagination with 2nd order recursive conditions filter

Hi John,

Thanks for helping but still no luck. I get this (expected) error :

Warning (512): SQL Error: 1054: Unknown column 'User.parent_id' in
'where clause' [/Users/thomas/Sites/Cake/1.2.5/cake/libs/model/
datasources/dbo_source.php, line 525]

Query: SELECT COUNT(*) AS `count` FROM `campaigns` AS `Campaign` LEFT
JOIN `user_campaigns` AS `UserCampaign` ON (`Campaign`.`id` =
`UserCampaign`.`id`) WHERE `User`.`parent_id` = 204

Query: SELECT `Campaign`.`id`, `Campaign`.`name`,
`Campaign`.`description`, `Campaign`.`active` FROM `campaigns` AS
`Campaign` LEFT JOIN `user_campaigns` AS `UserCampaign` ON
(`Campaign`.`id` = `UserCampaign`.`id`) WHERE `User`.`parent_id` = 204
ORDER BY `Campaign`.`id` asc LIMIT 20

The real problem is : is it possible with Cake to filter a model with
a condition under a related model, and how to do that?
