Re: 3 models and search condition
Solution
After reading this:
http://bakery.cakephp.org/articles/view/get-the-find-query-sql-rather-than-query-result
First get the id's of the locations from the offers corresponding to a
certain category
$this-Offer-recursive = 0;
$options = array(
'conditions' = array(
'Offer.category_id' = $id),
'fields' = 'Offer.location_id',
'recursive' = -1
);
$location_ids =
$this-Offer-find(sql,$options);
Than get the actual locations
$location_options = array(
'conditions' = array(
'Location.id IN ('.$location_ids.')'
),
'contain' =
array('Offer','LocationsPicture')
);
$locations = $this-Location-find('all',
$location_options);
$this-set('locations',$locations);

Re: 3 models and search condition
Ok, if you accept using two finds, then you can do it with CakePHP
find types.
[code]
$offer_locations = $this-Offer-find(
'list', array(
'fields' = array(
'id',
'location_id'
),
'conditions' = array(
'Offer.category_id' = $id
)
)
);
$locations = $this-Location-find(
'all', array(
'contain' = array(
'Offer',
'LocationsPicture'
),
'conditions' = array(
'Location.id' = $offer_locations
)
)
);
[/code]
That will give the same result as yours. By passing the result of the
find('list'), which is an array, to the conditions in the find('all'),
CakePHP will automatically assume that IN is wanted for the
Location.id condition.
Hope you find this helpful, and congratulation with you success :)
Enjoy,
John

3 models and search condition
I have 3 tables (travel agency): Categories (Mountain, Sea etc.) Locations (London, Paris etc.) Offers (id,category_id,location_id) When I select a category, I want to display the locations that are found in the offers of that category. Categories and Locations are not related. -- View this message in context: http://old.nabble.com/3-models-and-search-condition-tp28866040p28866040.html Sent from the CakePHP mailing list archive at Nabble.com.

Re: 3 models and search condition
Ok, I understand what you want to do! So you have the three models, they are related as: Category hasMany Offer Location hasMany Offer Offer belongsTo Category Offer belongsTo Location So what is your issue? Do you have a problem with the find() statement?

Re: 3 models and search condition
Yes. I want to display the locations that are found in the offers of a particular category. When the user selects the Category with, let's say id 3, I want to display the locations that are found in the offers of that category and I don't know how. -- View this message in context: http://old.nabble.com/3-models-and-search-condition-tp28866040p28866212.html Sent from the CakePHP mailing list archive at Nabble.com.

Re: 3 models and search condition
I suggest you study the section about retrieving data in the CakePHP book at: http://book.cakephp.org/view/1017/Retrieving-Your-Data Set the recursive parameter to 2 when you retrive the data in the Category model, like: [code] $this-find( 'all', array( 'conditions' = array( 'Category.id' = $id ), 'recursive' = 2 ) ); [/code] Try it out! Later when you are more comfortable with the find statement, take a look at the Containable behavior in the CakePHP book at: http://book.cakephp.org/view/1323/Containable Using that will make your find statements easier to work with.

Re: 3 models and search condition
Yeap, I know about the Containable behaviour. The problem with retrieving the categories is another. If I get all the categories, I'm gonna probably need to retrieve the location from the offers associated with the Category. If I have 100 offers for a category (with the same location), I'm gonna get that location a hundred times. -- View this message in context: http://old.nabble.com/3-models-and-search-condition-tp28866040p28866287.html Sent from the CakePHP mailing list archive at Nabble.com.

Re: 3 models and search condition
A correction to part of the pseudo-code :) [code] 'Offer' = array( 'Offer.category_id' = $id ) [/code] should be: [code] 'Offer' = array( 'conditions' = array( 'Offer.category_id' = $id ) ) [/code] You can attach a condition on the related models! Enjoy, John On Jun 12, 8:41 pm, John Andersen j.andersen...@gmail.com wrote: You should be able to make a find with conditions on the category even if you are retrieving the data from the Location model. Something like: [code] find( 'all', array( 'contain' = array( 'Offer' = array( 'Offer.category_id' = $id ) ) ) ); [/code] That should give you all Location records for the Offers with category_id equal the requested id!

Re: 3 models and search condition
Tried that:
$locations = $this-Location-find(
'all', array(
'contain' = array(
'Offer' = array(
'conditions' =
array('Offer.category_id' = $id)
)
)
)
);
Doesn't work
