I've been trying all night to update a record like this:
$r = $this->Question->read(NULL, $question['Question']['id']);
debug($r);// This is a complete Question array
$this->Question->set('status', 'version');
$s = $this->Question->save();
//$s = $this->Question->save($r['Question']);//this also doesn't work
debug($s); // = False every time!! Why??
exit;
The two comments show variations I've tried but didn't work either.
@Dipesh:
$this->data = $this->Question->read(NULL, $question['Question']['id']);
$this->Question->status = 'version';
$s = $this->Question->save($this->data);
debug($s);
exit;
@Dipesh II:
$this->request->data = $this->Question->read(NULL, $question['Question']['id']);
debug($this->data);
//$this->Question->status = 'version';
$this->request->data['Question']['status'] = 'version';
$s = $this->Question->save($this->request->data);
//$s = $this->Question->save($r['Question']);
debug($s);
exit;
@Dipesh III: (removed)
Use $this->data instead of $r
Example
$this->data = $this->Question->read(NULL, $question['Question']['id']);
$this->set is used to set variable value and pass it to view so view can access it where as $this->data represent the data to be stored in database.
If You're using Cake 2.0 then replace $this->data which is read only in Cake 2.0 to $this->request->data.
It's not very "automagical" but I was able to get this working like this:
$set_perm_id = 42;//who cares
$data = array(
'Question'=> array(
'id'=> $question['Question']['id'],
'perm_id'=> $set_perm_id,
'status'=>'version'
)
);
$s=$this->Question->save($data);
Basically I'm just building the data array manually. If anyone knows why this works instead of what I was doing before, I'd love to hear it.
Just try these lines..
$this->Question->id = $question['Question']['id'];
$this->Question->set('status','version');
$this->Question->save();
OR
$aUpdate["id"] = $question['Question']['id'];
$aUpdate["status"] = "version";
$this->Question->save($aUpdate);
cakePHP provide a method called set() in both Models::set() as well as in Controller::set();
About Controller::set() This method is used to set variables for view level from any of the controller method. For example fetching records and from models and setting them for views to display it to clients, like this
$data = $this->{ModelName}->find('first');
$this->set('dataForView',$data) // now you can access $data in your view as $dataForView
About Model::set() This method is used to set data upon a model, the format of the array that will be passed must be same as that used in Model::save() method i.e. like this
$dataFormModel = array('ModelName'=>array('col_name'=>$colValue));
$this->{ModelName}->set($dataForModel);
Model::set() will accept its parameter only in this format, once successfully set you can do following
validate this data against the validation rules specified in model directly like this
$isValid = $this->ModelName->validate();
save/update data by calling Model::save()
