So I created a table to test and can't save simple data. I did cake bake model Test, so entity and table models should be fine. Also, connection to the database is fine since other models are been saved correctly. Controller.php:
public function test(){
if ($this->request->is('post')){
$this->loadModel('Test');
$test = $this->Test->newEntity();
$test = $this->Test->patchEntity($test,[
'field_1'=>24,
'field_2'=>12
]);
$this->Test->save($test);
}
I checked with debug and $this->Test and the $test object are created fine. Still I get this error:
