I have a table in MySQL which have a ManyToMany field and I want truncate the table, but when I try it, I obtain the following error:

`ERROR 1701 (42000): Cannot truncate a table referenced in a foreign key constraint ...`

I'm using Symfony with Doctrine but if it is possible, I'm interested in learn how to do it through console

```
class Project {

  /**
  * @ORM\ManyToMany(targetEntity="Shipping", mappedBy="projects")
  **/
  private $employee;
}

class Employee{

  /**
  * @ORM\ManyToMany(targetEntity="Product", inversedBy="employee")
  * @ORM\JoinTable(name="middle_table")
  **/
  protected $projects;
}

```
