Doctrine 2 Issue - php

Question

I am trying to learn the framework Doctrine 2. I have a Model in MySQL and implement it in Doctrine. After the implementation of the dependency between the two classes Task and Dropdown list, it doesnt operate.
My code is:
<?php
use Doctrine\Common\Collections;
use Doctrine\ORM\Mapping AS ORM;
/**
* Task
*
* #Table(name="task")
* #Entity
*/
class Task
{
/**
* #var integer
*
* #Column(name="ID", type="integer", nullable=false)
* #Id
* #GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var Dropdownlist
* #ORM\OneToMany(targetEntity="Dropdownlist", mappedBy="tasks")
* #ORM\JoinColumn(name="priority", referencedColumnName="id")
*/
protected $priority;
/**
* #var string
*
* #Column(name="Label", type="string", length=45, nullable=true)
*/
private $label;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set priority
*
* #param integer $priority
*
* #return Task
*/
public function setPriority($priority)
{
$this->priority = $priority;
return $this;
}
/**
* Get priority
*
* #return integer
*/
public function getPriority()
{
return $this->priority;
}
/**
* Set label
*
* #param string $label
*
* #return Task
*/
public function setLabel($label)
{
$this->label = $label;
return $this;
}
/**
* Get label
*
* #return string
*/
public function getLabel()
{
return $this->label;
}
}
/**
* Dropdownlist
*
* #Table(name="dropdownlist")
* #Entity
*/
class Dropdownlist
{
/**
* #var integer
*
* #Column(name="ID", type="integer")
* #Id
* #GeneratedValue(strategy="IDENTITY")
*/
private $id;
/**
* #var string
*
* #Column(name="PriorityLabel", type="string", length=45, nullable=true)
*/
private $prioritylabel;
/*
* #var ArrayCollection
* #ORM\ManyToOne(targetEntity="Task", inversedBy="priority")
*/
protected $tasks;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set prioritylabel
*
* #param string $prioritylabel
*
* #return Dropdownlist
*/
public function setPrioritylabel($prioritylabel)
{
$this->prioritylabel = $prioritylabel;
return $this;
}
/**
* Get prioritylabel
*
* #return string
*/
public function getPrioritylabel()
{
return $this->prioritylabel;
}
public function getTasts(){
return $this->tasks;
}
public function __construct()
{
}
}
Problem:
The database schema is not in sync with the current mapping file.
What is the reason?
Where is the problem?
Best regards

Answer 1

It means your database is not in sync with your current mapping.
Run doctrine:schema:update --complete --dump-sql to see which changes need to be done. You can also run doctrine:schema:update --complete --force to deploy the changes directly.
