Symfony，控制器中的ManyToMany方法

Question

I have little problem with ManyToMany setters and getters

Company.php

/**
* @ORM\ManyToMany(targetEntity="User", mappedBy="companies")
*/
protected $employees;

User.php

    /**
    * @ORM\ManyToMany(targetEntity="Company", inversedBy="employees")
    * @ORM\JoinColumn(name="company_id")
    */
protected $companies;

then in Controller I try set user value into company

$company->setEmployees($company->getEmployees($user));

I keep getting

"Attempted to call an undefined method named "setEmployees" of class ..\\Entity\\Company". Did you mean to call eg "addEmployees" or "getEmployees"?

Can someone help me out? Thanks!

Answer 1

That is because of your ManyToMany relation between your two entities. By default, the getters & setters will become setEmployee() (singular, because it is used to add a single Employee object) and addEmployees() (plural, because it is used to add an array of Employees). Check out if everything is spelled correctly and respects this principle.

Given that $user seems to be a singular user, I'd make the following change :

$company->setEmployee($company->getEmployees($user));

Hope this helps.
