I have the output array from a $Model->find() query which also pulls data from a hasMany relationship:
Array(
[Parent] => Array
(
[id] => 1
)
[Child] => Array
(
[0] => Array
(
[id] => aaa
[score] => 3
[src] => stage6/tn~4bbb38cc-0018-49bf-96a9-11a0f67883f5.jpg
[parent_id] => 1
)
[1] => Array
(
[id] => bbb
[score] => 5
[src] => stage0/tn~4bbb38cc-00ac-4b25-b074-11a0f67883f5.jpg
[parent_id] => 1
)
[2] => Array
(
[id] => ccc
[score] => 2
[src] => stage4/tn~4bbb38cc-01c8-44bd-b71d-11a0f67883f5.jpg
[parent_id] => 1
)
)
)
I'd like to transform this output into something like this, where the child id is the key to additional child attributes:
Array(
[aaa] => Array
(
[score] => 3
[src] => stage6/tn~4bbb38cc-0018-49bf-96a9-11a0f67883f5.jpg
)
[bbb] => Array
(
[score] => 5
[src] => stage0/tn~4bbb38cc-00ac-4b25-b074-11a0f67883f5.jpg
)
[ccc] => Array
(
[score] => 2
[src] => stage4/tn~4bbb38cc-01c8-44bd-b71d-11a0f67883f5.jpg
)
}
Is there an easy way to use Set::extract, Set::combine, Set::insert, etc. to do this efficiently? I cannot figure it out.
I've used Set::combine to do this a few times, but I can't make an argument for efficiency. As an example, I had a list of volunteers and each of those volunteers belonged to a group. I wanted to retrieve each committee and its volunteers, but as an associative array keyed by the committee name. Here's the code I used to do that:
$volunteers = Set::combine (
$this->Volunteer->Committee->find (
'all',
array ( 'order' => 'display_order' )
),
'{n}.Committee.title',
'{n}.Volunteer'
);
Hopefully that helps. The documentation for Set::combine may help elaborate on the details.
As Rob says, Set::combine is the answer to your question. Here's a sample solution, using the XPath 2.0 syntax:
$parents = $this->Parent->find('all');
$assocChildren = Set::combine( $parents, '/Child/id', '/Child' );

I want to show All Courses for a particular Category in ctp file as in form. As For Category Arts there are 4 Courses.
I want to display these 4 Courses for Arts Category.
I am able to Display Categories using the same array.
But not able to display Courses using same array in y ctp file as dropdown in a form.
Is there a way to Access this Courses data? Or Do I have to use different query for to access Courses??
Please I need your help with this.
Thanks in advance.
I would solve it like this:
An improved retrieving Query which only outputs the course names.
$cats = $this->Category->find('all',array(
'conditions'=>array('Category.Category-name'=>'Arts')
'recursive'=>1,
'contain'=>array('Course'),
'fields'=>'Course.course-name'))[0]['Course'];
Now the $cats variable should contain an array with 4 entries which can be used in a dropdown select
Hi i don't know what is wrong with the threaded of cakephp 2 please help
when i use threaded without condition it will show its children
$category = $this->Category->find('threaded');
output:
Array
(
[0] => Array
(
[Category] => Array
(
[id] => 11
[name] => Affinity Collection
[parent_id] => 0
[lft] => 25
[rght] => 30
[alias] => affinity-collection
[status] => 0
)
[children] => Array
(
[0] => Array
(
[Category] => Array
(
[id] => 113
[name] => Core samples
[parent_id] => 11
)
)
)
but when i use this with condition it won't show its parent
$this->Category->find('threaded',array('conditions'=>array('Category.id'=>11)));
output:
Array
(
[0] => Array
(
[Category] => Array
(
[id] => 11
[name] => Affinity Collection
[parent_id] => 0
[lft] => 25
[rght] => 30
[alias] => affinity-collection
[status] => 0
)
[children] => Array
(
)
)
)
please help why it is not showing the children when use with condition
I think the problem is because you are asking for all categories with an id of 11. Insted you should ask for all categories that are children of categorie 11.
You could use your left and right columns to get a nested array (keyword Tree behaviour). Try this:
$parentCategorie = $this->Categorie->find('first', array(
'conditions' => array(
'Categorie.id' => 11
)
);
$children = $this->Categorie->find('first', array(
'conditions' => array(
'Categorie.lft BETWEEN ? AND ?' => array($parentCategorie['Categorie']['lft'], $parentCategorie['Categorie'])['rght']
)
);
Probably the best chance you have to achive what you want is to use the children method of the Tree behavior.
You coul use it as follows
$parent=$this->Category->find('first',
array('conditions'=>array('Category.id'=>11)));
$this->Category->children($parent['Category']['id']);
I need to get multiple records from model, then put them into request->data for a view to render into a form with multiple input fieldsets for example name='data[Applicant][0][display_name]'. name='data[Applicant][1][display_name]'...data value goes in for each applicant.
Actually I've already done what i want, but i do not think it is a good method to do so.
Appreciate if anyone can guide me
foreach ($this->Applicant->data['Applicant'] as $key=>$item){
$data['Applicant'][] = $item['Applicant'];
}
$this->request->data = $data;//set Model to data
$this->set('data' , $this->Applicant->data);
$this->Applicant->data is the following:
Array
(
[Applicant] => Array
(
[0] => Array
(
[Applicant] => Array
(
[id] => 1
[application_id] => 17
[name] => User
[first_name] =>
...
)
)
[1] => Array
(
[Applicant] => Array
(
[id] => 3
[application_id] => 17
[name] =>
[first_name] =>
the following is the desired output (less one level):
Array
(
[Applicant] => Array
(
[0] => Array
(
[id] => 1
[application_id] => 17
[name] => User
[first_name] =>
...
)
[1] => Array
(
[id] => 3
[application_id] => 17
[name] =>
[first_name] =>
thanks
This should suffice:
$this->request->data['Applicant'] = Hash::extract( $this->Applicant->data, 'Applicant.{n}.Applicant' );
When I try to create a new entry of Template with the $data array, the models of Template, Group and Product are saved correctly. But the nested Calcfield (which is a hasMany of Group) is not saved. :( Group and Product are hasMany of Template.
Is this possible at all?
$this->Template->create();
$this->Template->saveAll($data, array('validate' => false));
// $data looks like this:
Array
(
[Template] => Array
(
[title] =>
[shorttitle] => Wie auch immer
[place] => Hannover
[size] =>
)
[Group] => Array
(
[0] => Array
(
[title] => Hosting
[order] =>
[Calcfield] => Array
(
[0] => Array
(
[title] => Hosting
[value] => 0
[description] =>
)
[1] => Array
(
[title] => Strom
[value] => 0
[description] =>
)
)
)
)
[Product] => Array
(
[0] => Array
(
[share] => 10
[businessunit] => Marketing
)
[1] => Array
(
[share] => 30
[businessunit] => intl. CRM
)
)
)
No, recursive saves are not possible, as far as I know. You would need to stick those in a separate array and then save them after the initial save.
Since CakePHP 2.1 it's possible to save deeply-nested models using the deep parameter in saveAll (since CakePHP 2.1)
ref. http://book.cakephp.org/2.0/en/models/saving-your-data.html?highlight=saveall#model-saveassociated
say I have an array like this:
[Option] => Array
(
[0] => Array
(
[id] => 30606
[option_description_id] => 1
[product_id] => 101512
[price] => 0
[OptionDescription] => Array
(
[id] => 1
[option_type_id] => 1
[name] => Factory
[short_name] =>
[sort_order] => 1
[OptionType] => Array
(
[id] => 1
[name] => Warranty
[seo_url] => warranty
)
)
)
[1] => Array
(
[id] => 30607
[option_description_id] => 2
[product_id] => 101512
[price] => 44.99
[OptionDescription] => Array
(
[id] => 2
[option_type_id] => 1
[name] => +2 Year Extended
[short_name] =>
[sort_order] => 2
[OptionType] => Array
(
[id] => 1
[name] => Warranty
[seo_url] => warranty
)
)
)
I want to extract the option whose OptionDescription's option_type_id ID is 1
Is there a way to do this easily with Set::extract?
Well, of course, two minutes after I post my question (after hours of trying to figure it out) I realize how easy it is.
In order to extract a parent element, you use /.. in your path syntax.
So my line for all the Options whose type_ids are 2 would be:
Set::extract('/Option/OptionDescription[option_type_id=2]/..', $product);
