php - Cakephp - Cannot set Model->id in KeyValue Behavior::beforeSave -

i'm trying implement key/value behavior based on https://github.com/josegonzalez/cakephp-keyvalue

my behavior insert new rows database each new key form submission, regardless number of keys, , update existing records if user_id , key found in keyvalue table. have linked user model keyvalue model, behavior.

when database has no record of user_id/key, insert new records correctly. found if trying update existing key-value pairs of same user, first 2 values updated correctly last value submitted produce new record.

after investigation found in saving loop in beforesave(), if assign id model in beforesave() $model->id before returning true, not passed model->save() class.

i'm using cake 2.5.4

model->id in beforesave not pass model->save() in lib/model/model.php:# 1841

if ($count > 0) {         $cache = $this->_prepareupdatefields(array_combine($fields, $values));          **pr($this->id); //this value empty**          if (!empty($this->id)) {             $this->__safeupdatemode = true;             try {                 $success = (bool)$db->update($this, $fields, $values);             } catch (exception $e) {                 $this->__safeupdatemode = false;                 throw $e;             }             $this->__safeupdatemode = false;         } 

keyvaluebehavior:

public function beforesave(model $model, $options = array()) {     extract($this->options[$model->alias]);     $keys = array_keys($model->data[$model->alias]);     $data = $model->data;      if (in_array($fields['key'], $keys) && in_array($fields['value'], $keys)) {         return true;     }      if (isset($data[$model->alias]) && ! empty($data[$model->alias])) {         $datatemplate = array($model->alias => array());          foreach ($data[$model->alias] $field => $value) {             if ($model->hasfield($field)) {                 $datatemplate[$model->alias][$field] = $value;                 unset($data[$model->alias][$field]);             }         }          $index = 0;          foreach ($data[$model->alias] $key => $value) {             $index ++;             $insert = $datatemplate;             $insert[$model->alias][$fields['key']] = $key;              if ($uniquekeys) {                 $model->deleteall(reset($insert));             }              $insert[$model->alias][$fields['value']] = $value;              //check existing key value                   $belongsto = reset($model->belongsto);                                   $existing = $model->find('first', array(                 'conditions' => array(                      $belongsto['foreignkey'] => $insert[$model->alias][$belongsto['foreignkey']],                      $fields['key'] => $insert[$model->alias][$fields['key']]                 )             ));                $model->create();                            if(sizeof($existing) > 0){                                   $existingkv = reset($existing);                 //pr($existingkv);                 $model->read(null, $existingkv['id']);             }               if ($index == count($data[$model->alias])) {                 // if model->id set here, not passed model->save()                 $model->id = $existingkv['id'];                 $model->data = $insert;                 pr($model); // model->id set here not in model->save()                 return true;             } else {                 pr($insert); //updates correctly                 if (false === $model->save($insert)) {                                       return false;                 }             }          }     } 

userscontroller:

public function test() {     if ($this->request->is('post')) {         $this->userdetail->create();         $this->request->data['userdetail']['user_id'] = $this->auth->user('id');         if ($this->userdetail->save($this->request->data)) {             $this->session->setflash(__('the userdetail has been saved'));           //  $this->redirect(array('action' => 'index'));         } else {             $this->session->setflash(__('the userdetail not saved. please, try again.'));         }     }    $users = $this->userdetail->user->find('list');    $this->set(compact('users')); } 

then have 3 sample fields in view view/users/test.ctp:

<?php echo $this->form->create('userdetail'); echo $this->form->input('field1'); echo $this->form->input('field2'); echo $this->form->input('field3'); echo $this->form->end('submit'); 

to workaround added key named "id_holder" model in beforesave(), , edited model/model.php. don't want edit cakephp core.

edit: on new savekeyvalues() method:

public function savekeyvalues(model $model, $data){     if($model == null || $data == null){         return false;     }      if (isset($data[$model->alias]) && ! empty($data[$model->alias])) {         $datatemplate = array($model->alias => array());         foreach ($data[$model->alias] $field => $value) {             if ($model->hasfield($field)) {                 $datatemplate[$model->alias][$field] = $value;                 unset($data[$model->alias][$field]);             }         }     }      $belongsto = reset($model->belongsto);     $index = 0;      foreach ($data[$model->alias] $key => $value) {         $index++;          $insert = $datatemplate;         $insert[$model->alias][$this->options[$model->alias]['fields']['key']] = $key;         $insert[$model->alias][$this->options[$model->alias]['fields']['value']] = $value;         $insert[$model->alias][$belongsto['foreignkey']] = $data[$belongsto['foreignkey']];         //check existing key value         $existing = $model->find('first', array(             'conditions' => array(                 $belongsto['foreignkey'] => $data[$belongsto['foreignkey']],                 $this->options[$model->alias]['fields']['key'] => $key             )         ));          //reset create/update         $model->create();         if(sizeof($existing) > 0){             $existingkv = reset($existing);             $model->read(null, $existingkv['id']);         }          if (false === $model->save($insert)) {             return false;          }         if($index == count($data[$model->alias])){             return true;         }     } }
