Cake php count distinct - cakephp

How can this Cakephp query be made to count distinct?
$matches = $this->Product->find('count', array(
'conditions' => array(
"Product.brand_id" => $brand['Brand']['id'],
'Product.active' => 1
));


Something like this?
$matches = $this->Product->find('count', array(
'fields' => 'DISTINCT Product.brand_id',
'conditions' => array("Product.brand_id" => $brand['Brand']['id'],
'Product.active' => 1)
));

How to Group and Order by in cakephp

How can I group by fields and Order by DESC in cakephp?
$this->set('messages', $this->Message->find('all',array('conditions' => array('Message.receiver_id'=>$this->Session->read('Auth.User.id')),'group' => array('Message.user_id'),'order' => array('max(Message.created) ASC'))));

Records are fetched in cakePhp depend on a model is
$records = $this->Model->find('all', array(
'conditions' => array(conditons),
'fields' => array(fieldlist),
'group' => array('Model.column'),
'order' => array('Model.column', 'Model.column2 DESC')
));
From your code, you can write as
$data = $this->Message->find('all', array(
'conditions' => array( 'Message.receiver_id'=>$this->Session->read('Auth.User.id')),
'group' => array('Message.user_id'),
'order' => array('max(Message.created) ASC')
));
$this->set('messages', $data);

$records = $this->Model->find('all', array(
'conditions' => array(conditons),
'recursive' => -1,
'fields' => array(fieldlist),
'group' => array('Model.column'),
'order' => array('Model.column', 'Model.column2 DESC')
));
If you want to order by latest Message inserted then instead of sort by created use sort by id like this Model.id DESC'

CakePHP 2.1 Custom Pagination

I am using cakephp 2.1 and defined 3 tables as follows.
`industries(id, name);`
`movies(id, name, industry_id),`
`trailers(id, name, movie_id);`
I want to paginate the trailers for particular industry. So the code I have written is below:
$this->paginate = array(
'Industry' => array(
'contain' => array(
'Movie' => array(
'order' => 'Movie.release DESC',
'Trailer' => array(
'conditions' => array(
'Trailer.id !=' => $trailer_id
)
)
)
),
'conditions' => array(
'Industry.id' => $id
)
)
);
If I would specify 'limit' for 'Trailer', I get correct number of results but some null array for a movie which doesn't contain any trailers. Please help me to get the number of specified limit of trailers for particular industry. The work will be most appreciated.

It looks to me like you've got your contain key in the wrong place. It should be defined before the models.
<?php
$this->paginate = array(
'contain' => array(
'Industry' => array(
'Movie' => array(
'order' => 'Movie.release DESC',
'Trailer' => array(
'conditions' => array(
'Trailer.id !=' => $trailer_id
)
)
)
)
),
'conditions' => array(
'Industry.id' => $id
)
);

cakephp how to find belongs to by id

Is there a way in cakephp using ORM to get the item that belongs to a specific child item. For example I was to get the related Post record for a specific Comment records.
This is my Comment model:
var $belongsTo = array(
'Post' => array(
'className' => 'Post',
'foreignKey' => 'post_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
I was trying this but it's pull back every post, even those that don't have the comment I'm querying against:
$this->Post->contain('Comment');
$results = $this->Post->find('all', array(
'contain' => array(
'Comment' => array(
'conditions' => array(
'id' => 15
)
)
)));
Any other way to do this?

Are you sure you don't have to specify the model in your conditions?
For example:
$this->Post->contain('Comment');
$results = $this->Post->find('all', array(
'contain' => array(
'Comment' => array(
'conditions' => array(
'Comment.id' => 15
)
)
)));

my research led me to this post regarding the issue with contains:
http://nuts-and-bolts-of-cakephp.com/2008/07/17/forcing-an-sql-join-in-cakephp/
so my final solution was as follows:
$this->Post->unbindModel(array('hasMany' => array('Comment')));
$results = $this->Post->bindModel(array('hasOne' => array(
'Comment' => array(
'foreignKey' => false,
'conditions' => array('Comment.post_id = Post.id'))
)));
$results = $this->Post->find('all', array(
'conditions' => array(
'Comment.id' => 10
)));
not pretty but gets the job done :)

cakephp find() question

I want to convert following mysql statement into cakephp query syntax.Please help me. Here is my query.SELECT * FROM post WHERE (user_id == $id OR awarded_to = $id ) AND id = $id
Here is my cakephp query. is it wrong.
$this->Post->find('all',
array('conditions' => array('OR' =>
array('Post.user_id' => $id),
array('Post.awarded_to' => $id)
),
'AND' =>
array('Post.id' => $id)
))

This one's on the house, but next time read the docs.
$this->Post->find('all', array(
'conditions' => array(
'OR' => array(
array('Post.user_id' => $id),
array('Post.awarded_to' => $id)
),
'Post.id' => $id
)
));
The 2 OR arrays need to be inside an array themself, and there's no need for AND.

Just add Post.id = $id below the OR condition without you give "and" it's automatic read as and condition...
$this->Post->find('all', array(
'conditions' => array(
'OR' => array('Post.user_id' => $id),
array('Post.awarded_to' => $id)
),
'Post.id' => $id
));

You are very close with your query, just you need little modification like to remove 'AND' in conditions array after 'OR' as:
$this->Post->find('all', array(
'conditions' => array(
'OR' => array(
array('Post.user_id' => $id),
array('Post.awarded_to' => $id)
),
'Post.id' => $id
)
));
Or
$this->Post->find('all', array(
'conditions' => array(
'Post.id' => $id
)
));
The second option will be the best for you if you are passing tables primary key 'id' in AND conditions.

cakephp - find conditions over multiple models

I am trying to do a find with conditions in two models. Is this possible ?
$offices = $this->User->Org->find('first', array(
'conditions' => array(
"or" => array(
'Org.website LIKE' => $match,
'Domain.domain' => $match
)
)
));
The relationship looks like this
'Domain' => array(
'className' => 'Domain',
'foreignKey' => 'org_id',
),
As a containable search
$this->User->Org->Behaviors->attach('Containable');
$offices = $this->User->Org->find('first', array(
'contain' => array(
'Domain' => array(
'conditions' => array(
'Or' => array(
'Domain.domain' => $match
)
)
),
'Office' => array(
'fields' => array('Office.id', 'Office.city')
)
),
'conditions' => array(
"or" => array(
'Org.website' => $match
)
)
));
Thanks

It's possible as long as your level of recursion is set appropriately, but I highly recommend using the Containable Behavior for something like this. It makes this things trivial, readable and surgical (you get what you need and only what you need).
