CakePHP 2.0 fetching Containable fields - cakephp

'Tag' => array(
(int) 0 => array(
'id' => '1',
'name' => 'kannada',
'MoviesTag' => array(
'id' => '60',
'movie_id' => '2',
'tag_id' => '1'
)
)
)
I want to fetch Movie from movie_id of Tag in containable.. How to fetch that?

In your Tag controller try something like this:
$this->Tag->find('all'); // this will return tag with movie detail
OR
if you want to use Containable behavior then try this:
$this->Tag->attach->behaviors('Containable');
$this->Tag->recursive = -1;
$this->Tag->find('all', array(
'fields' => array('Tag.id', 'Tag.name'),
'contain' => array(
'Movie'
)
));

CakePHP join only the latest entry

I have 2 tables :
ORDERS
------
id
type
LOGS
----
id
order_id
time
I want to query with cakephp so I have :
array(
'Order' => array(
'id' => '38',
'type' => 'online',
),
'Log' => array(
'time' => '2014-09-24 21:17:14'
)
)
The problem is that I want only the last order, not all orders with all logs.
I did something like this :
$ordersList = $this->Order->find('all', array(
'fields' => array(
'Order.*',
'Log.time'
),
'joins' => array(
array(
'table' => 'logs',
'alias' => 'Log',
'type' => 'right',
'conditions' => array(
'Log.order_id = Order.id'
),
)
),
);
To have only the last one, you can order the result by log.time and then take only the first record (with the param 'first' or just by fetching the first record of the recordset).
For example :
$order = $this->Order->find('first', array(
'order' => array('Log.time' => 'desc')
));
in your case :
$ordersList = $this->Order->find('first', array(
'fields' => array(
'Order.*',
'Log.time'
),
'joins' => array(
array(
'table' => 'logs',
'alias' => 'Log',
'type' => 'right',
'conditions' => array(
'Log.order_id = Order.id'
),
'order' => array('Log.time' => 'desc')
)
),
);
As information, if you want to have a simple method to join the models, take a look at the containable behavior. With this behavior, the link are setted in the model then you only have to declare which associated model you want to retrieve with your current model.

CakePHP: why does format of data retrieved depend on which associated model is called

I have a site with the usual sort of sellers, items and images. The models look like this:
class Seller extends AppModel {
$hasMany = array('Item');
...
}
class Item extends AppModel {
$belongsTo = array('Seller')
$hasMany = array('Image');
...
}
class Image extends AppModel {
$belongsTo = array('Item');
...
}
My problem is that when I retrieve a list of Items, the data comes out in a different format depending on whether I am getting a list of all Items (to display to the public) in the ItemsController, or the details of a Seller and their Items in the SellersController.
Briefly Item->find('all') retrieves an array of
array( 'Item' => array( <item stuff> ),
'Images' => array of array( <image stuff> ) );
whereas the Seller->find('first', ...) retrieves the Items as
array( 'Seller' => array( <seller stuff> ),
'Item' => array of array ( <item stuff>
'Images' => array of array( <image stuff> ) );
In the 2nd case the Images element is nested within the Item part. Having the data formatted so differently makes it harder to re-use View code. Also my Item afterFind() won't work properly has problems when the Images bit isn't where it expects it to be.
QUESTION
Is there a simple way to prevent the 'Images' part being nested within the 'Item' part in the 2nd situation?
I am using Cake 2.4
Formats in More Detail
All items:
// in ItemsController.php
debug($this->Item->find('all'));
produces this:
array(
(int) 0 => array(
'Item' => array(
'id' => '1',
'title' => 'tom item 1',
'seller_id' => '1'
),
'Seller' => array(
'id' => '1',
'name' => 'tom'
),
'Images' => array(
(int) 0 => array(
'id' => '1',
'item_id' => '1',
'path' => 'tom_1_1'
),
(int) 1 => array(
'id' => '2',
'item_id' => '1',
'path' => 'tom_1_2'
)
)
),
(int) 1 => array(
'Item' => array(
'id' => '2',
'title' => 'tom item 2',
'seller_id' => '1'
),
'Seller' => array(
'id' => '1',
'name' => 'tom'
),
'Images' => array(
(int) 0 => array(
'id' => '3',
'item_id' => '2',
'path' => 'tom_2_1'
),
(int) 1 => array(
'id' => '4',
'item_id' => '2',
'path' => 'tom_2_2'
)
)
),
...
A single Seller + associated Items:
// In SellersController.php
debug($this->Seller->find('first',
array('conditions' => array('id' => $id), 'recursive' => 2)));
produces:
array(
'Seller' => array(
'id' => '1',
'name' => 'tom'
),
'Item' => array(
(int) 0 => array(
'id' => '1',
'title' => 'tom item 1',
'seller_id' => '1',
'Seller' => array(
'id' => '1',
'name' => 'tom'
),
// Look! 'Images' is WITHIN 'Item !!!
'Images' => array(
(int) 0 => array(
'id' => '1',
'item_id' => '1',
'path' => 'tom_1_1'
),
(int) 1 => array(
'id' => '2',
'item_id' => '1',
'path' => 'tom_1_2'
)
)
),
(int) 1 => array(
'id' => '2',
'title' => 'tom item 2',
'seller_id' => '1',
'Seller' => array(
'id' => '1',
'name' => 'tom'
),
'Images' => array(
(int) 0 => array(
'id' => '3',
'item_id' => '2',
'path' => 'tom_2_1'
),
(int) 1 => array(
'id' => '4',
'item_id' => '2',
'path' => 'tom_2_2'
)
)
),
....
This is the expected and correct behavior as Image is not directly associated with Seller, but with Item.
Imagine, how would you determine the proper association when Image would be defined on the same level as Item? That would indicate an association with Seller which doesn't exist.
If you want a different structure, format it in your afterFind callback or wherever it's appropriate. However, I wouldn't recommend trying to work against the CakePHP standards. In case applicable, adapt your view code.
Your question is not clear to me. If just wants to prevent Image to coming in 2nd case, try this
$this->Seller->Item->unbindModel(array(
'hasMany' => array('Image')
));
$result = $this->Seller->find('first',
array('conditions' => array('id' => $id), 'recursive' => 2)));
debug($result);

Containable to do show deeper data or join table

I have 3 tables: projects, project_reminder_users, project_types.
The relations is as follow:
Project => belong to => ProjectType
hasMany => ProjectReminderUser
ProjectReminderUser => belong to => Project
ProjectType => hasMany => Project
I get all data based on who assigned(ProjectReminderUser) by this
$this->Project->ProjectReminderUser->Behaviors->load('Containable');
$this->paginate = array(
'ProjectReminderUser' => array(
'limit' => $limit,
'contain' => array(
'Project' => array(
'ProjectComment',
'ProjectFile',
),
'User'
),
'conditions' => array(
'User.group_id' => $this->Session->read('Auth.User.group_id'),
'ProjectReminderUser.user_id' => $this->Session->read('Auth.User.id'),
'Project.project_status_id' => PROJECT_STATUS_OPEN,
),
'order' => 'Project.due_date',
)
);
$this->set('myTasks', $this->paginate('ProjectReminderUser'));
and the result look like this
array(
'ProjectReminderUser' => array(
'id' => '96',
'user_id' => '1',
'project_id' => '46'
),
'Project' => array(
'id' => '46',
'project_type_id' => '9',
'contact_id' => null,
'company_id' => null,
'subject' => 'Test Modified Field',
'description' => 'Test Modified Field',
'ProjectFile' => array(
(int) 0 => array(
'id' => '19',
'project_id' => '46',
'user_id' => '6',
'file_path' => '46_bhbinary_xmm_1728.jpg',
'notes' => null,
'created' => '2013-11-26 18:37:49'
),
),
'ProjectComment' => array(
)
),
'User' => array(
'password' => '*****',
'id' => '1',
'group_id' => '1',
'email' => 'xxx#xxxxx.com',
'first_name' => 'xxxx',
'deleted' => false,
'displayName' => 'xxxxx'
)
)
In the result There is data for Project.project_type_id, but I would like to have more detail of that. So I can show it as name instead of number. maybe like ProjectType.name instead.
How can I achieve this, so I can sort it in the view? something like this
$this->Paginator->sort('ProjectType.name', 'Type');
The problem is that Paginator doesn't play nice with deep model associations. I think though if rather than using Cake's methods for doing model associations, you instead do your joins manually, you may be able to work out the sorting as you want. See the below discussion.
http://sinkpoint.railsplayground.net/cakephp-pagination-deep-sort-and-habtm/
Worst comes to worse, you may have to also rewrite the model's paginate function to deal with sorting how you need it to.
How about
'contain' => array(
'Project' => array(
'ProjectComment',
'ProjectFile',
'ProjectType',
),
'User'
),
Looks like you did not contain "ProjectType"

cakephp habtm nested data

I have a HABTM relationship and I'd like to get nested data for a categories table from a product table something like this product array:
array(
(int) 0 => array(
'id' => (int) 1,
'name' => 'a',
'categories' => array(
(int) 0 => array(
'id' => (int) 1
),
(int) 1 => array(
'id' => (int) 2
)
)
),
(int) 1 => array(
'id' => (int) 2,
'name' => 'b',
'categories' => array(
(int) 0 => array(
'id' => (int) 1
)
)
)
)
Is this possible with cake?
EDIT: I will try to explain further what I want to do.
Please bear with me, I am new to cake and am having trouble getting to grips it.
I have a 'product' table:
public $hasAndBelongsToMany = array(
'Category' => array(
'className' => 'Category',
'joinTable' => 'categories_sculptures',
'foreignKey' => 'sculpture_id',
'associationForeignKey' => 'category_id',
'unique' => 'keepExisting'
)
)
and a category table:
public $hasAndBelongsToMany = array(
'Sculpture' => array(
'className' => 'Sculpture',
'joinTable' => 'categories_sculptures',
'foreignKey' => 'category_id',
'associationForeignKey' => 'sculpture_id',
'unique' => 'keepExisting'
)
);
and a category products table:
public $belongsTo = array(
'Category' => array(
'className' => 'Category',
'foreignKey' => 'category_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Sculpture' => array(
'className' => 'Sculpture',
'foreignKey' => 'sculpture_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);
I would like to build a view table of the sculptures and also show in each row which categories each sculpture is in (which could be more than one). As I am new to cake I don't know how I would go about this. If I was just querying mysql I could get this information with a group_concat or a nested select, or inefficiently by looping through first array and querying the category_sculpture table by sculpture key and adding the results to the first array. But I would like to know the best way to get this result the cake way.
I have found the answer to my needs:
$this->Sculpture->recursive = 1;

Containable Nested models

I have a few nested models which I'm trying to load using Containable behaviour in CakePHP.
Most of it works fine.
However, 1 model that has a hasMany relation only returns 1 object:
$article = $this->News->find('first',array(
'conditions'=>array('News.id'=>$id),
'contain' => array(
'Newslayout',
'Newspicture'=> array(
'NewspicturesProduct' => array(
'Product' => array(
'Brand',
'Category'
)
)))
));
The object only being loaded once is the relation Newspicture hasMany NewspicturesProduct
When I log the queries, I get the following:
SELECT `NewspicturesProduct`.`id`, `NewspicturesProduct`.`x`, `NewspicturesProduct`.`y`, `NewspicturesProduct`.`product_id`, `NewspicturesProduct`.`newspicture_id`, `NewspicturesProduct`.`w`, `NewspicturesProduct`.`h` FROM `edclondon`.`newspictures_products` AS `NewspicturesProduct` WHERE `NewspicturesProduct`.`newspicture_id` = 3
Which gives me 3 results in phpMyAdmin. But only 1 in CakePHP's debug:
'Newspicture' => array(
(int) 0 => array(
'id' => '3',
'news_id' => '2',
'newspicture_file_path' => '5022443f-ddf8-4115-ae57-618e9d60b047.jpg',
'newspicture_file_size' => '1232546',
'order' => null,
'NewspicturesProduct' => array(
'id' => '1',
'x' => '0.180664',
'y' => '0.295312',
'product_id' => '3',
'newspicture_id' => '3',
'w' => '0.286133',
'h' => '0.478125',
'Product' => array(
'id' => '3',
//....
'Brand' => array(
'id' => '6',
//...
),
'Category' => array(
'id' => '6',
//....
)
)
)
)
When retrieving the Newspictures object rather then retrieving the News object, I do get all 3 NewspicturesProduct objects.
It seems to me that the code corresponding the query you showed should be:
$article = $this->News->find('first',array(
'contain' => array(
'Newslayout',
'Newspicture'=> array(
'NewspicturesProduct' => array(
'conditions'=>array('NewspicturesProduct.newspicture_id'=>'3')
'Product' => array(
'Brand',
'Category'
)
)))
));
and not the one you gave...
It seems you need 3 records from NewspicturesProduct. If that then you can try:
$article = $this->News->find('first',array(
'contain' => array(
'Newslayout',
'Newspicture'=> array(
'NewspicturesProduct' => array(
'conditions'=>array(
'limit'=> 3
),
'Product' => array(
'Brand',
'Category'
)
)))
));
