How to debug when CakePHP Model::save() doesn't attempt an INSERT

Question

I am having a bear of a time saving the simplest record from a model called ItemView:

if($this->save($this->data)) {
  echo \'worked\';
} else {
  echo         


        

Answer 1

To debug Model->save() check the validation errors and the last sql query

$this->Model->save($data);

debug($this->Model->validationErrors); //show validationErrors

debug($this->Model->getDataSource()->getLog(false, false)); //show last sql query

Answer 2

What is the name of controller you are using?

Mismatching the name of controller and model also cause some errors. If you are using Posts controller then the Post model should be used. If you are using Post model inside other controller; say BlogsController then the Post model should be loaded like following:

    <?php
    class BlogsController extends AppController
    {
        public function index()
        {
            $this->loadModel("Post");    
            //Here I'm loading other model inside blogs controller
            if($this->request->is('post'))
            {
                $this->Post->save($this->request->data);
            }
        }
    }
    ?>

Answer 3

It may be, Validations returns false.. You can check like

$this->Model->save($this->data, false);

Put false and check whether now data inserts, if it is then it is validation error

Answer 4

What always gets me is that if I modify the actual table (usually by adding attributes to it), then you must flush your cache. Usually just deleting everything inside the following two folders does the trick for me:

tmp > cache > models 
tmp > cache > persistent

Answer 5

Same problem here. I wasted 2 hours of my life.

Solution: I forget to this:

array('post', 'put')

Answer 6

In cakephp 3.x, you can debug during insert/update

if ($this->TableName->save($entity)) {
      // success 
} else {
// if not save, will show errors 
  debug($entity->errors());

}
