Right, so my data returns in the following way,
(int) 0 => array(
'MODEL-XX' => array(
//DATA HERE
'xxs_id' => '11',
'aas_id' => '44',
'vvs_id' => '2'
),
'xxs' => array(
'id' => '11',
'customername' => 'XX name here'
),
'aas' => array(
'id' => '44',
'clientname' => 'aa name here',
'xxs_id' => '11'
),
'vvs' => array(
'id' => '2',
'start' => '1405296000',
'end' => '1405814400',
'users_id' => '1'
)
This works fine, but I want to know how to link my users table to this model. So the details of each user for my VV model would become apart of the data. My MODEL-XX does not have any links with my users table so the place I need to call in the users details are held with my VV model.
I have been looking into this but have not been able to find a simple easy method for doing this?
I was thinking that this would be doable with my model, so I opened my my XX model and added the following within my '$belongsTo' section,
'Users' => array(
'className' => 'Users',
'foreignKey' => 'vvs.users_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
So is there a easy method for linking data like this?
Please give me time, if I have not explained myself right or not enough data, please tell me and let me fix or explain better.
Thanks,
Either set your recusive higher:
$this->MODEL-XX->recursive = 1; //or 2
Or and this should be your prefered way to go, start using the containable behaviour:
http://book.cakephp.org/2.0/en/core-libraries/behaviors/containable.html
In your appModel:
public $actsAs = array('Containable');
Then try this find:
$this->MODEL-XX->recursive = -1;
$data = $this-MODEL-XX>find(
'all', array(
'conditions' => $conditions,
'contain' => array('xxs', 'aas', 'vvs', 'user')
)
);
I might be 'vvs.user' but I forgot what is used for deeper models

I have two Models, namely Product and ProductSpecification which have the following relations in place:
(Product Model)
public $hasMany = array(
'ProductSpecification' => array(
'className' => 'ProductSpecification',
'foreignKey' => 'product_id',
'dependent' => true
)
);
and
(ProductSpecification Model)
public $belongsTo = array(
'Product' => array(
'className' => 'Product',
'foreignKey' => 'product_id'
)
);
Using the CakePHP Form helper I post ProductSpecification data and then I use the saveAll method (or saveAssociated, I've tried both) to save the data. debug($this->request->data) gives me the following output after POSTing:
array(
'Product' => array(
'id' => '2'
),
'ProductSpecification' => array(
'title' => 'test',
'step' => '1',
'position' => '1'
)
)
This is great, right..? Now, the line after the debug I use the following code to save (I've also tried saveAssociated):
if($this->Product->saveAll($this->request->data))
For some odd reason this saves three(!) empty rows in my ProductSpecification table, with only the product_id field (and id) set; the fields title, step and position are empty. Exactly the same behavior happens when I run saveAssociated. What am I doing wrong?
I'm running CakePHP 2.x.
Your save data should look more like this:-
array(
'Product' => array(
'id' => '2'
),
'ProductSpecification' => array(
array(
'title' => 'test',
'step' => '1',
'position' => '1'
)
)
);
The values for ProductSpecification need to be passed as a numerically indexed array for the hasMany relationship.
Also, make sure you use saveAssociated() rather than saveAll() as you are passing associated data so there is no need to use the wrapper method (which should be avoided wherever possible).
I have a database:
Companies | Users | Files
- ID - ID - ID
- company_id - user_id
So for my models:
Company hasmany User
User belongsto Company & hasmany File
File belongsto User
How can I list al the files belonging to a company? Without the user and company data? So a single array listing files.
I could fetch all the user IDs followed by a query in File searching with these IDs. But I was wondering, is there a best practice cakePHP way?
I'm fairly new to cake.
Thanks
As far as I know it's not possible to get company files without any user or company data, but you can limit the data by using the Containable behaviour. For example, if you want to get files that belong to a company in the company controller you could use this:
$users = $this->Company->User->find('all', array(
'conditions' => array('User.company_id' => $id),
'fields' => array('id', 'company_id'),
'contain' => array('File'),
));
The result ($users) would look something like this:
array(
0 => array(
'User' => array(
'company_id' => '75',
'id' => '51'
),
'File' => array(
0 => array(
'id' => '399',
'user_id' => '51',
...
),
1 => array(
'id' => '337',
'user_id' => '51',
...
)
...
)
)
1 => array(
'User' => array(
'company_id' => '75',
'id' => '65'
),
'File' => array(
0 => array(
'id' => '450',
'user_id' => '65',
...
),
...
)
)
)
You can then get an array of files using the Hash utility.
$files = Hash::extract($users, '{n}.File.{n}');
Which will give you something like this:
array(
0 => array(
'id' => '399',
'user_id' => '51',
...
),
1 => array(
'id' => '337',
'user_id' => '51',
...
),
3 => array(
'id' => '450',
'user_id' => '65',
...
),
...
)
Don't forget to enable the behaviour. I suggest you do it in your app model by adding the following line:
public $actsAs = array('Containable');
CakePHP will not help you on this and even if want to write mysql query you cant do this by using files table only until and unless you will add company_id in files table.
As I understood from the cakephp-documentation, one of the advantages of the 'containable'-Behavior is being able to fetch fewer data if you need fewer data...
But that doesn't seem to work in my case of a connection between users and usergroups.
My associations look like:
Group
hasMany: Membership
User
hasMany: Membership
Membership
belongsTo: User, Group
(I'm not using HABTM, instead use the Model 'Membership' in between to join users and groups).
All Models implement the 'Containable'-Behavior.
Now I want to get all the members of a group with a certain id, only their ids and mail-addresses. My query is built like that:
$members = $this->Membership->find('all', array(
'conditions' => array(
'group_id' => $id
),
'contain' => array(
'User' => array(
'fields' => array('id', 'fullName')
),
)
));
But the resulting array looks like:
array(
(int) 0 => array(
'Membership' => array(
'id' => '1',
'group_id' => '1',
'user_id' => '1',
'role' => 'member'
),
'Group' => array(
'id' => '1',
'name' => 'Foo Group'
),
'User' => array(
'password' => '*****',
'id' => '1',
'name' => 'Dr. Foo'
'mail' => 'foo#bar.baz',
'role' => 'admin'
)
)
)
So there are definietely more fields fetched than I wanted to... (it's the same thing btw wenn I set the 'contain'-key to:
'contain' => array(
'User.fullName', 'User.id'
)
Am I using the containable-behavior wrong?
Your models don't seem to be acting containabl-y at all. Have you set your models to act as containable?
class Post extends AppModel {
public $actsAs = array('Containable');
}
If so, maybe the problem is with the recursion (to avoid getting the Group array with the query). Containable behavior should handle the recursion level on its own, but try setting it on the AppModel just to be sure
class AppModel extends Model {
public $actsAs = array('Containable');
public $recursive = -1;
Your first attempt
'contain' => array(
'User' => array(
'fields' => array('id', 'fullName')
),
)
looks good in terms of syntax, so it probably the actAs thing.
Also, for debugging also, try
$this->Membership->contain('User');
$this->Membership->find('all', array(
'conditions' => array(
'group_id' => $id
));
and see if you get the expected results that way.
I am using Cakephp 2.2.4 and I need to retrive a list of Lead that belongs to the user (id = 106).
The result of the query is:
array(
(int) 0 => array(
'Lead' => array(
'id' => '6',
'user_id' => '106',
'date' => '2012-12-31 22:15:23',
'ip' => '127.0.0.1',
'service_id' => '1',
'location' => 'Rome',
'message' => 'Message Message',
'telephone' => null,
'active' => null
),
'User' => array(
'id' => '106',
'email' => 'daje#daje.it',
'pwd' => '0433c024cb08be13000d59a347e640482843f46f177e95749dc6599c259617fd3491dcb940b47693cbbc7f65a2cc5ef62deca2e600c1be133ad54170f7d1fbd1',
'role_id' => '3',
'active' => '1'
),
'Service' => array(
'id' => '1',
'name' => 'Primo servizio'
),
'Estimate' => array(
(int) 0 => array(
'id' => '1',
'lead_id' => '6',
'user_id' => '106'
)
)
)
)
It looks good but I need to count the Estimates (Estimate array), I would like to retrive the number of the estimates, and not the array with all the fields (of estimates table).
How can i do it?
I need :
Lead array as it shown
User array as it shown
Service array as it shown
Estimate (only the total number of the estimates... in this case 1)
The find is very simple:
$options = array('conditions' => array('User.id' => 106));
debug($this->Lead->find('all', $options));
Try something like this, not 100% sure it'll work but worth a go if not I'd advise trawling the cakephp docs for retrieving your data:
$options = array(
'fields' => array('Lead.*', 'User.*', 'Service.*', 'count(Estimate.id)'),
'conditions' => array('User.id' => 106)
);
Without diving too far into the internals of the Cake ORM, assuming you don't need to do this immediately at query time, couldn't you just get the count of the estimate array programmatically after the fetch?
http://php.net/manual/en/function.count.php
$leads = $this->Lead->find('all',$options);
foreach($leads as $lead){
//get the number of estimates for every lead result
$lead_num = count($lead['Estimate']);
}
Alternatively, you could manually write a join query for this one fetch and execute it using the Cake Model class's query method. Without knowing the specifics of your table schema and model relations its hard to give specifics about how to structure the query, but this shouldn't be too difficult by just look at your table spec and extracting a sql COUNT statement for every Estimate with given id.
In Cakephp is there a better way to write this:
$unread_orders = $this->Order->find('all', array('conditions' => array('Order.status' => 'unread') ));
$read_orders = $this->Order->find('all', array('conditions' => array('Order.status' => 'read') ));
$dispatched = $this->Order->find('all', array('conditions' => array('Order.status' => 'dispatched'), 'limit' => 5));
$canceled = $this->Order->find('all', array('conditions' => array('Order.status' => 'canceled'), 'limit' => 5));
There is a limit on the dispatched and canceled items.
It's seems like there would be a more effcient way of doing this, in one call to the database instead of 4.
Cheers.
One way is to do
$orders_read_unread = $this->Order->find('all', array('conditions' => array('OR' => array(array('Order.status' => 'unread'), array('Order.status' => 'read')))));
$orders_disp_cancel = $this->Order->find('all', array('conditions' => array('OR' => array(array('Order.status' => 'canceled'), array('Order.status' => 'dispatched'))), 'limit' => 5));
EDIT: Updated queries. Thanks Mark for clarifying.
<?php
...
$orders_read_unread = $this->Order->find( 'all', array(
'conditions' => array( 'Order.status' => array( 'unread', 'read' )),
'group' => array( 'Order.status' ),
));
/**
* Use this if you need 5 of EITHER canceled OR dispatched order
* if you need 5 of EACH you need to break it into two queries.
*/
$orders_dispatched_canceled = $this->Order->find( 'all', array(
'conditions' => array( 'Order.status' => array( 'canceled', 'dispatched' )),
'group' => array( 'Order.status' ),
'limit' => 5
));
/**
* Use these if you need 5 of EACH dispatched AND canceled orders
*/
$orders_dispatched = $this->Order->find( 'all', array(
'conditions' => array( 'Order.status' => 'dispatched' ),
'group' => array( 'Order.status' ),
'limit' => 5
));
$orders_canceled = $this->Order->find( 'all', array(
'conditions' => array( 'Order.status' => 'canceled' ),
'group' => array( 'Order.status' ),
'limit' => 5
));
...
?>
Should do the trick for you without having to deal with the 'OR' key syntax. It will generate a slightly less efficient IN ARRAY( '..' ,'..' ) syntax but keeps the php a little cleaner.
As an alternative you could look at either sub-queries - which are a pain with Cake. The book has an example of using the query builder via the datasource to inject a query into the conditions array of a normal cake find call.
http://book.cakephp.org/view/1030/Complex-Find-Conditions
And remember both of these finds should be in the model inside a function - you can either define a custom find type or just call a model function directly from your controller.
