I have this on a HABTM statement:
$this->set('usergroups', $this->User->find('first', array('conditions' => array('User.id' => $this->Auth->user('id')))));
This gets groups that are associated to the user id via a courses_users table.
This works perfectly find, except I also need to find all groups that a user doesn't belong to. How do I get the opposite of the statement above?
I used 'not' as a condition, and it still gave me the same result.
Thanks!
Something like this should work:
$user = $this->User->find('first', array(
'conditions' => array(
'User.id' => $this->Auth->user('id')
)
));
$otherGroups = $this->Group->find('all', array(
'conditions' => array(
'NOT' => array('id' => Hash::extract($user, '{n}.Group.id'))
)
));
Side Note: You should really be setting recursive to -1 in your AppModel and not relying on recursive to return additional data. Instead, use CakePHP's Containable Behavior.

I have the following problem with CakePHP:
Two tables are joined (filters and accounts). Then I am building conditions and only the second condition Account.active =>1 gets executed. If I print the result, there are still showing filters that are having another mode_id than 3.
$joins= array(
array('table' => 'filters',
'alias' => 'Filter',
'type' => 'right',
'conditions' => array(
'Filter.account_id = Account.id',
)
),
);
Then I execute the request including joins and conditions
$activeAccounts = $this->Account->find('all',array(
'conditions'=>array('AND'=>array('Filter.mode_id'=>3,'Account.active'=>1)),
'joins'=>$joins));
The models were checked and no problems identified. Filter belongs to Account. Account has many Filter.
Below the query that is generated. The results are still showing filters with Filter.mode_id other than 3
Here is the query that is generated. The results are still containing rows with Filter.mode_id other than 3 despite the fact that one condition is 'Filter.mode_id'=>3
SELECT `Account`.`id`, `Account`.`user_id`, `Account`.`name`,
`Account`.`api_key`, `Account`.`account_number`, `Account`.`remaining_balance`,
`Account`.`investment_size`, `Account`.`active`
FROM `baseline_db`.`accounts` AS `Account`
right JOIN `baseline_db`.`filters` AS `Filter`
ON (`Filter`.`account_id` = `Account`.`id`)
WHERE ((`Filter`.`mode_id` = 3) AND
(`Account`.`active` = '1'))
Like say Oldskool, use the Model associations
and for your condition, The "AND" is not necessary,
you cant put :
$activeAccounts = $this->Account->find('all',array(
'conditions' => array(
'Filter.mode_id'=>3,
'Account.active'=>1
)
));
the request you want to make with the type of relation you have, seem to me weird.
If i understand, perhaps with something like that :
$this->loadModel('Filter');
$filters =$this->Filter->find("list", array(
'conditions' => array('Filter.mode_id' => 3),
'fields' => array('Filter.account_id')
));
$activeAccounts = $this->Account->find('all',array(
'conditions' => array(
'Account.account_id'=>$filters,
'Account.active'=>1
)
));
I am using cakephp 2.4.5. I want to find the last record of an associated table. Below is my code
$Latest = $this->ParentModel->find('first',array(
'conditions' => array('ParentModel.id'=>$id),
'order' => array('ParentModel.AssociatedModel.id' => 'DESC')
));
This code has missing column error with ParentModel.AssociatedModel.id but the id column is definitely there. Does it look right in the first place? If not, how can I fix this part or is there a better implementation? Thank you
Have you tried to read the manual about retrieving data? It is clearly explained there.
If AssociatedModel is somehow associated with one of the four association types with ParentModel, you'll have to use this syntax:
$Latest = $this->ParentModel->find('first',array(
'contain' => array('AssociatedModel'),
'conditions' => array('ParentModel.id' => $id),
'order' => array('AssociatedModel.id' => 'DESC')
));
Make sure the other model is included by using recursive or contain(). See this page about Containable.
If your field name in the DB is really containing a dot CakePHP2 will have a problem with that because it uses the dot notation as separator. At least I've never used a dot in a database field, it's doable but doesn't make much sense and obviously breaks Cake, no idea if you can work around that.
You can't do "cross conditions" though associated models, but you can use Containable behavior to filter associated models.
For this, you have to bind the behavior to your model through:
public $uses = array('Containable');
And then do your query:
$this->ParentModel->find('first', array(
'conditions' => array('ParentModel.id' => $id),
'contain' => array(
'AssociatedModel' => array(
'limit' => 1,
'order' => array('id DESC')
)
)
));
This will give you the parent model, and the last associated model.
I guess it should be like this
$Latest = $this->ParentModel->AssociatedModel->find('first',array(
'conditions' => array('ParentModel.id'=>$id),
'order' => array('AssociatedModel.id DESC')
));
Check if it is correct.
I'm using the containable behavior to look at several tables.
$this->paginate = array(
'contain' => array(
'Co' => array('fields' => array('ref')),
'CoItemType' => array('fields' => array('name')),
'Casing' => array(
'fields' => array('id','barcode','CONCAT(plant_dot,size_dot,product_line_dot,production_week) as dot'),
'Customer' => array('fields' => array('company_name')),
)
)
);
This works as expected. However I am integrating this with jQuery datatables and the way dataTables passes over conditions it does not specifiy a field. So I'd like to do conditions outside of the contains like so...
'conditions' = array(
'OR' => array(
array("Table.field_name LIKE " => '%'.$parameter.'%'),
array("Table.field_name LIKE " => '%'.$parameter.'%'),
array("Table.field_name LIKE " => '%'.$parameter.'%')
)
)
Of course this is not possible since the containable behavior wants you to include the conditions under the tables key in the contain array. This is frustrating, does anyone have a solution or workaround around to this problem?
I am using CakePHP 2.x
Use Linkable Behavior as noted in comments.
I have hasMany Through table which is Chats table with Chat model and I'm using loadModel in User controller to load Chat model then ran below query to bindModel with Chat.user_id and User.id :
$this->loadModel('Chat');
$this->Chat->bindModel(array(
'belongsTo' => array(
'User' => array(
'foreignKey' => false,
'conditions' => array('Chat.user_id = User.id')
)
)
));
$lastChat = $this->Chat->find('all', array(
'conditions' => array(
'Chat.receiver_id' => $user_id['User']['id']
),
'order' => array('Chat.id DESC'),
'fields' => array(
'Chat.id',
'Chat.chat',
'Chat.user_id',
'Chat.receiver_id',
'Chat.read',
'Chat.created'
),
'group' => array('Chat.user_id')
));
I want to join those tables together but this does not seem to work in Cake way I tried with normal SQL query and it works fine.
What could be wrong here?
Have you tried setting the recursive property before the find? Eg:
$this->Chat->recursive = 3;
You may need to set this after $this->Chat->bindModel, but I am not sure if this will make a difference or not. You will also need to re-bind the User model before each find, if, for example, your find queries are run within a loop ...
I'm using the Containable behavior to get a list of Comments (belongsTo Post, which belongs to Question; Question hasMany Post, and Post hasMany Comments; all of these belong to Users).
$data = $this->Question->find ( 'first',
array ('contain' =>
array ('User',
'Post' => array ('User', /* 'order' => 'User.created DESC'*/ )
)
)
);
It works, when I comment out the section in comments above. I suppose this is to be expected, but what I want is all of the Posts that are found, should be sorted in order of the 'created' field of the 'User' they belong to. How do I accomplish this deeper level sorting in CakePHP? I always get, "Warning (512): SQL Error: 1054: Unknown column 'User.created' in 'order clause'"
Thanks for your help!
Also, you might be trying to group on a related table from a find call that doesn't use joins.
Set your debug level to something greater than 1 so you can see the query log and make sure that Cake isn't doing two queries to fetch your data. If that is the case then the first query is not actually referencing the second table.
If you want to manually force a join in these situations you can use the Ad-Hoc joins method outlined by Nate at the following link.
http://bakery.cakephp.org/articles/view/quick-tip-doing-ad-hoc-joins-in-model-find
I have found two ways to get around this.
The first is to define the second level associacion directly in the model.
Now you will have access to this data everywhere.
It should look something like this.....
var $belongsTo = array(
'Foo' => array(
'className' => 'Foo', //unique name of 1st level join ( Model Name )
'foreignKey' => 'foo_id', //key to use for join
'conditions' => '',
'fields' => '',
'order' => ''
),
'Bar' => array(
'className' => 'Bar', //name of 2nd level join ( Model Name )
'foreignKey' => false,
'conditions' => array(
'Bar.id = Foo.bar_id' //id of 2nd lvl table = associated column in 1st level join
),
'fields' => '',
'order' => ''
)
);
The problem with this method is that it could make general queries more complex than they need be.
You can thus also add the second level queries directly into te find or paginate statement as follows: (Note: I found that for some reason you can't use the $belongsTo associations in the second level joins and will need to redefine them if they are already defined. eg if 'Foo' is already defined in $belongsTo, you need to create a duplicate 'Foo1' to make the association work, like the example below.)
$options['joins'] = array(
array('table' => 'foos',
'alias' => 'Foo1',
'type' => 'inner',
'conditions' => array(
'CurrentModel.foo_id = Foo1.id'
)
),
array('table' => 'bars',
'alias' => 'Bar',
'type' => 'inner',
'foreignKey' => false,
'conditions' => array(
'Bar.id = Foo1.bar_id'
)
)
);
$options['conditions'] = array('Bar.column' => "value");
$this->paginate = $options;
$[modelname] = $this->paginate();
$this->set(compact('[modelname]'));
I hope this is clear enough to understand and that it helps someone.
Check your recursive value. If it's too limiting, it will ignore the containable links, IIRC. I remember bumping into this a few times. I'd try containing multiple models, but my recursive option was set to 0 and nothing would get pulled. For your example, I'd think that a value of 1 (the default) would suffice, but maybe you've explicitly set it to 0 somewhere?
You can add before your call to find() the following:
$this->Question->order = 'Question.created DESC';
Yeah, I couldn't work out how to sort based on the related/associated model, so ended up using the Set::sort() method. Checkout this article for a good explanation.
// This finds all FAQ articles sorted by:
// Category.sortorder, then Category.id, then Faq.displaying_order
$faqs = $this->Faq->find('all', array('order' => 'displaying_order'));
$faqs = Set::sort($faqs, '{n}.Category.id', 'ASC');
$faqs = Set::sort($faqs, '{n}.Category.sortorder', 'ASC');
...And yes, it should probably be a Category->find() but unfortunately the original developer didn't code it that way, and I didn't wanna rework the views.
