I am new in cakephp and I have searched a lot but couldn't get the solution. My query is not returning any error but it doesn't join the zone table with the disposeTemp table.
public function disposePreview(){
$this->loadModel('DisposeTemp');
$joins = array(
array(
'table' => 'zones',
'alias' => 'Zone',
'type' => 'inner',
'conditions' => array('DisposeTemp.zone = Zone.id')
)
);
$options = array(
'conditions' => array('DisposeTemp.is_delete' => 0,'DisposeTemp.status'=>2),
'order' => array('Item.item_category_id' => 'asc'),
'joins' => $joins
);
$getDT = $this->DisposeTemp->find('all', $options);
debug($getDT);
exit;
}
Set foreign key false , as you are not having proper naming convention for foreign key in DisposeTemp table , it was supposed to be zone_id to auto form relationship.
Now in your situation Use.
$joins = array(
array(
'table' => 'zones',
'alias' => 'Zone',
'type' => 'inner',
'foreignKey' => FALSE,
'conditions' => array('DisposeTemp.zone = Zone.id')
)
);

I am new in cakephp and trying my best to implement queries in cakephp.
I have this query
SELECT * FROM question join question_topic on question.question_id=question_topic.question_id join topic on topic.topic_id=question_topic.topic_id join user_topic on user_topic.topic_id=topic.topic_id where user_topic .user_id=10
I need this in cakephp.
What I have tried is this
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User',
'UserInfo.UserTopic'=>array(
'conditions'=>array('UserTopic.user_id'=>10)
),
'QuestionAndTopic.Topic','UpVoteQuestion','Answer','Answer.UserInfo'
),
'order' => 'rand()',
'recursive' => 0
));
But the query is not giving me a right results. Could you please take a look.
Question.php
class Question extends AppModel
{
public $useTable = 'question';
public $primaryKey = 'question_id';
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'fields' => array('User.user_id','User.email','User.active')
),
'UserInfo' => array(
'className' => 'UserInfo',
'foreignKey' => 'user_id',
)
);
public $hasMany = array(
'Answer' => array(
'className' => 'Answer',
'foreignKey' => 'question_id',
),
'QuestionAndTopic' => array(
'className' => 'QuestionAndTopic',
'foreignKey' => 'question_id',
)
);
public function latestQuestions(){
$this->Behaviors->attach('Containable');
return $this->find('all', array(
'contain' => array(
'User',
'UserInfo.UserTopic'=>array(
'conditions'=>array('UserTopic.user_id'=>10)
),
'QuestionAndTopic.Topic','UpVoteQuestion','Answer','Answer.UserInfo'
),
'order' => 'rand()',
'recursive' => 0
));
}
}
You can use Mysql query it will works as like as cakephp query
$this->Behaviors->query('SELECT * FROM question join question_topic on question.question_id=question_topic.question_id join topic on topic.topic_id=question_topic.topic_id join user_topic on user_topic.topic_id=topic.topic_id where user_topic .user_id=10');
Refer this link

);
$options['conditions'] = array(

$books = $Book->find('all', $options);
make changes as per you table and fields.hope this helps.
I have tables below with HABTM associations.
user, group , groups_users
group , project, projects_groups
public $hasAndBelongsToMany = array(
'Group' =>
array(
'className' => 'Group',
'joinTable' => 'groups_users',
'foreignKey' => 'user_id',
'associationForeignKey' => 'group_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',

'finderQuery' => ''
)
);
I am trying to get all users, as a list for checkboxes, that are on a project using project id using query below
$users = $this->User->Group->Project->find('list',
array(
'conditions' => array('Project.id' => $this->Session->read('Projectid'))
,'contain' => array(
'User' => array( 'fields' => 'User.id', 'User.email')
)
)
);
But error below
Model "Project" is not associated with model "User"
I have actually tried different ways to get this working but cant seem to get it right, how can i achieve what i want. cheers
I achieved what i wanted with joins , is there a way to do this by using model associations, instead of the manual joins option?
$options['joins'] = array(
array('table' => 'groups_users',
'alias' => 'gu',
'type' => 'LEFT',
'conditions' => array(
'gu.user_id = User.id',
)
),
array('table' => 'projectGroups',
'alias' => 'pg',
'type' => 'LEFT',
'conditions' => array(
'pg.group_id = gu.group_id',
)
)
);
$this->User->recursive = -1;
$options['conditions'] = array(
'pg.project_id = ' => $this->Session->read('Projectid'),
'User.Active = ' => true
);
$users = $this->User->find('list', $options);
I have this inner join query in a paginated model called Application
Application has many AssignedExploration
AssignedExploration belongs to Exploration
Exploration belongs to ExplorationCategory
ExplorationCategory belongs to Season
My query so far is:
$session_condition = array(
'table' => 'assigned_explorations',
'alias' => 'AssignedExploration',
'type' => 'INNER',
'conditions' => array(
'AssignedExploration.application_id = Application.id',
'OR' => array(
array('AssignedExploration.label' => $this->request->named['filter_session'])
)
)
);
I would like to add another query inside the OR that will get applications which has a Season.name = fall
I've tried adding array('Season.name' => 'fall') :
$session_condition = array(
'table' => 'assigned_explorations',
'alias' => 'AssignedExploration',
'type' => 'INNER',
'conditions' => array(
'AssignedExploration.application_id = Application.id',
'OR' => array(
array('AssignedExploration.label' => $this->request->named['filter_session']),
array('Season.name' => 'fall')
)
)
);
But no luck. Seems like Season is not recognized by AssignedExploration.
I would like to nest from AssignedExploration to Exploration to ExplorationCategory and to Season
And I don't have any idea on how to make it thru inner join query via cakephp.
Thanks in advanced.
EDIT: query as of now:
INNER JOIN
`ntc_development`.`assigned_explorations` AS `AssignedExploration` ON (
`AssignedExploration`.`application_id` = `Application`.`id`
AND
`AssignedExploration`.`label` = 'fall'
)
$this->paginate['Application'] = array(
'recursive' => -1,
'joins' => array(
array(
'table' => 'assigned_explorations',
'alias' => 'AssignedExploration',
'type' => 'inner',
'foreignKey' => true,
'conditions' => array('AssignedExploration.application_id = Application.id')
),
array(
'table' => 'seasons',
'alias' => 'Season',
'type' => 'inner',
'foreignKey' => true,
'conditions' => array('Season.id = Application.season_id') # whats your foregin key
),
),
'fields' => array(),
'conditions' => array('Season.name' => 'fail'),
);
I have Tables
Items, Attributes,Taxonomies, Taxonomy_attributes,Item_attributes.
Taxonomy_attributes have two fields attribute_id(which is a foreign key to id of attributes table) and taxonomy_id (which is a foreign key to id of taxonomies table).
On the other hand Item_attributes have two fields attribute_id(which is a foreign key to id attributes table) and item_id (which is a foreign key to of id items table).
Attributes table have following fields :- Name, Type and Checkable(which is either 0 or 1).
Items table have fields id and model.
Taxonomies table have fields if and name.
I want to add a method to Attribute model ,that returns list of all attributes with checkable equals 1 and join with items and taxonomies ,that return item model & taxonomy name for each attribute.
My code is as follows:-
public function getCheckables($checkable)
{
$data = $this->find('all',array(
'fields' => array('Attribute.name', 'Attribute.type', 'Item.model', 'Taxonomy.name'),
'conditions' => array('Attribute.checkable' => 1),
'joins' => array(
array(
'table' => 'item_attributes',
'alias' => 'ItemAttribute',
'type' => 'INNER',
'conditions' => 'ItemAttribute.Item_id = Item.id',
),
array(
'table' => 'items',
'alias' => 'Item',
'type' => 'INNER',
'conditions' => 'ItemAttribute.item_id = Item.id'
),
array(
'table' => 'taxonomy_attributes',
'alias' => 'TaxonomyAttribute',
'type' => 'INNER',
'conditions' => 'TaxonomyAttribute.Taxonomy_id = Taxonomy.id'
)
),
'recursive'=>-1
)
);
pr($data); die();
}
Can anybody guide me with the right code?
2 of your joins have the same condition : 'conditions' => 'ItemAttribute.Item_id = Item.id', in case of the first one, Item table was not yet joined and in case of the second one, because your first condition was wrong, the ItemAttribute table was not joined.
The actual Solution
public function getCheckables($checkable)
{
$data = $this->find('all',array(
'fields' => array('Attribute.name', 'Attribute.type', 'Item.model', 'Taxonomy.name'),
'conditions' => array('Attribute.checkable' => 1),
'joins' => array(
array(
'table' => 'item_attributes',
'alias' => 'ItemAttribute',
'type' => 'INNER',
'conditions' => 'ItemAttribute.attribute_id = Attribute.id',
),
array(
'table' => 'items',
'alias' => 'Item',
'type' => 'INNER',
'conditions' => 'ItemAttribute.item_id = Item.id'
),
array(
'table' => 'taxonomies',
'alias' => 'Taxonomy',
'type' => 'LEFT',
'conditions' => 'Item.category_id = Item.id'
)
),
'recursive'=>-1
)
);
pr($data); die();
}
$order = $this->Order->find('all', array(
'recursive' => 2,
'conditions' => array(
'Order.date' => $datefrom,
),
'joins' => array(
array(
'table' => 'purchase',
'alias' => 'Purchase',
'conditions'=> array(
'Purchase.pid = Order.pid',
)
),
array(
'table' => 'sales',
'alias' => 'Sales',
'conditions'=> array(
'Purchase.pid = Sales.pid',
)
),
),
));
Why does the above code doesn't select fields from purchase and sales, but only fields from order are returned. What is the necessary things to be added to make all data is returned. Thanks
Try this, I'm not sure if the 'type' and 'foreignKey' keys are required, but I typically include them when using the 'joins' key. Also I'm assuming the 'pid' is the correct foreign key.
$order = $this->Order->find('all', array(
'recursive' => -1,
'conditions' => array(
'Order.date' => $datefrom,
),
'joins' => array(
array(
'table' => 'purchase',
'alias' => 'Purchase',
'type' => 'INNER',
'foreignKey' => 'pid',
'conditions'=> array(
'Order.pid = Purchase.pid',
)
),
array(
'table' => 'sales',
'alias' => 'Sales',
'type' => 'INNER',
'foreignKey' => 'pid',
'conditions'=> array(
'Sales.pid = Purchase.pid',
)
),
),
));
If you already have relationships set up in the model, change the 'recursive' key to -1.
Just an idea,
'table' => 'purchase',
'alias' => 'Purchase',
isn't a typo, is it? Because I think, the usual name for the table according to cake-conventions would be 'purchases'... But I don't know your tables of course... ;)
First you need to create an association in Order Model file
Model:
public $hasMany = array(
'purchase' => array(
'className' => 'purchase',
'foreignKey' => 'pid',
'dependent' => true,
'counterQuery' => 'true'
),
'sales' => array(
'className' => 'sales',
'foreignKey' => 'pid',
'dependent' => true,
'counterQuery' => 'true'
),
);
Controller:
$order = $this->Order->find('all', array(
'recursive' => 2,
'conditions' => array(
'Order.date' => $datefrom,
)
);
Now you can get Order, Purchase and Sales related records.
Enjoy...
Controller::loadModel('User');
Controller::loadModel('Answer');
Controller::loadModel('Influence');
$users = $this->User->find('all', array('joins' => array(
array(
'table' => 'answers',
'alias' => 'Answer',
'type' => 'inner',
'foreignKey' => false,
'conditions' => array('Answer.user_id = User.id'),
),
array(
'table' => 'influences',
'alias' => 'Influence',
'type' => 'inner',
'foreignKey' => false,
'conditions' => array(
'Influence.user_id=Answer.user_id',
)
)
),'fields' => array(
'Answer.is_correct',
'Answer.answer',
'Answer.date as answered_date',
'Influence.signups',
'Influence.clicks',
'User.first_name',
'User.last_name',
'User.email',
'User.phone',
'User.flybuys' )
));
In order to get fields from other tables You should specify the fields you want.
