Why there are so many 'DESCRIBE' when I enable debug model?
As you can see, the 'describe' sql took (7+17+17) ms! Why they are there? Can I disable it? 1 DESCRIBE `aros` 7 7 7 2 DESCRIBE `acos` 7 7 17 3 DESCRIBE `aros_acos`7 7 17 --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups CakePHP group.

Re: Why there are so many 'DESCRIBE' when I enable debug model?
I find there is a sql which will took 17ms everytime when the action needs authentication in ACL model. That means if I use ACL database model in my application , there will always be 17ms was taken. Can someone give an explanation of this? //sql SELECT `Aco`.`id`, `Aco`.`parent_id`, `Aco`.`model`, `Aco`.`foreign_key`, `Aco`.`alias` FROM `acos` AS `Aco` LEFT JOIN `acos` AS `Aco0` ON (`Aco0`.`alias` = 'controllers') JOIN `acos` AS `Aco1` ON (`Aco1`.`lft` `Aco0`.`lft` AND `Aco1`.`rght` `Aco0`.`rght` `Aco1`.`alias` = 'Users') LEFT JOIN `acos` AS `Aco2` ON (`Aco2`.`lft` `Aco1`.`lft` AND `Aco2`.`rght` `Aco1`.`rght` AND `Aco2`.`alias` = 'activity') WHERE ((`Aco`.`lft` = `Aco0`.`lft` AND `Aco`.`rght` = `Aco0`.`rght`) OR (`Aco`.`lft` = `Aco2`.`lft` AND `Aco`.`rght` = `Aco2`.`rght`)) ORDER BY `Aco`.`lft` DESC //end On Mon, Mar 16, 2009 at 8:22 PM, Joshua josh...@gmail.com wrote: As you can see, the 'describe' sql took (7+17+17) ms!

Re: Why there are so many 'DESCRIBE' when I enable debug model?
My understanding is that this enables CakePHP Models to identify details about your schema. By extracting this metadata, the models can be further exploited by ohter areas in cake, such as the helpers. The form helper, for example uses the metadata to automatically set size and limits on fields in the generated HTML. As far as I'm aware, this information is cached, in tmp/models/*. This cache is used when not in debug mode. Hopefully someone else may be able to confirm or correct me if I'm wrong.

Re: Why there are so many 'DESCRIBE' when I enable debug model?
Richard is right. Describe does just that... describes the tables so that Cake can know that Article should have a tltle field and that it contains up to 255 characters and so on and so on... As Richard also writes this is cached but when you are in debug-mode you are expected to alter the database every now and then and this way you don't have to manually empty the cache every time you do that.
