Doctrine - ManyToOne with table between - php

Question

I want to create model which will have table users with reference to table CustomFieldValue nad table CustomField with reference to CustomFieldValue too. CustomFieldValue will have only id, value and two columns, one from users and second from CustomField. I want to have functionality like a dynamic adding a new fields in registration form. Is this good idea? If yes, please help me with this model, because it doesn't work:
User:
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string", length=25, unique=true)
*/
private $username;
/**
* #ORM\Column(type="string", length=64)
*/
private $password;
/**
* #ORM\ManyToMany(targetEntity="Role", inversedBy="users",cascade={"persist"})
*
*/
private $roles;
/**
* #ORM\Column(type="string", length=60, unique=true)
*/
private $email;
/**
* #ORM\Column(type="string", length=60)
*/
private $sex;
/**
* #ORM\ManyToMany(targetEntity="Region", inversedBy="users")
* #ORM\JoinColumn(name="region", referencedColumnName="id")
*/
private $region;
/**
* #ORM\ManyToMany(targetEntity="Type", inversedBy="users")
* #ORM\JoinColumn(name="type", referencedColumnName="id")
*/
private $type;
/**
* #ORM\Column(name="is_active", type="boolean")
*/
private $isActive;
/**
* #ORM\ManyToOne(targetEntity="CustomFieldValue",inversedBy="id")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $customValues;
CustomFieldValue:
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="value", type="string", length=255)
*/
private $value;
/**
*ORM\OneToMany(targetEntity="User", mapped-by="id")
*#ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
/**
*#ORM\OneToMany(targetEntity="CustomField", mapped-by="id" )
*#ORM\JoinColumn(name="field_id", referencedColumnName="id")
*/
private $field;
CustomField:
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="type", type="string", length=255)
*/
private $type;
/**
* #var boolean
*
* #ORM\Column(name="required", type="boolean")
*/
private $required;
/**
* #ORM\ManyToOne(targetEntity="CustomFieldValue", inversedBy="id")
* #ORM\JoinColumn(name="customfield_id", referencedColumnName="id")
*/
private $customValues;

Answer 1

Your mapping is a little off:
User Entity Should Be:
/**
* #ORM\ManyToOne(targetEntity="CustomFieldValue", inversedBy="user")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $customValues;
CustomFieldValue Should Be:
/**
*ORM\OneToMany(targetEntity="User", mappedBy="customValues")
*/
private $user;
/**
*#ORM\OneToMany(targetEntity="CustomField", mappedBy="customValues" )
*/
private $field;
CustomField should be:
/**
* #ORM\ManyToOne(targetEntity="CustomFieldValue", inversedBy="field")
* #ORM\JoinColumn(name="customfield_id", referencedColumnName="id")
*/
private $customValues;
You dont need the join columns when you are calling the mappedBy this already tells doctrine to look for the join column declaration on that field. For the mappedBy and inversedBy fields these are the fields that link the 2 together NOT the actual join column name.
