The target-entity cannot be found in 'AppBundle\Entity\User#bitcoinWallet' - php

Question

I am using Symfony 3 and want to map Entity Userto have many BitcoinWallet
My AppBundle\Entity\User.php looks like that:
<?php
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use Gedmo\Mapping\Annotation as Gedmo;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="user")
*/
class User extends BaseUser
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string
* #ORM\Column(type="string", length=255, nullable=true)
*/
protected $firstName;
/**
* #var string
* #ORM\Column(type="string", length=255, nullable=true)
*/
protected $lastName;
/**
* #ORM\Column(type="string", length=255, nullable=true)
* #Assert\File(maxSize="2048k")
* #Assert\Image(mimeTypesMessage="Please upload a valid image.")
*/
protected $profilePicture;
/**
* #Assert\Email(
* message = "The email '{{ value }}' is not a valid email.",
* checkMX = true
* )
*/
protected $email;
protected $emailCanonical;
/**
* #ORM\ManyToOne(targetEntity="BitcoinBundle\Entity\BitcoinWallet")
* #ORM\JoinColumn(name="bitcoin_wallet", referencedColumnName="id")
*/
protected $bitcoinWallet;
/**
* #var \DateTime $created
*
* #Gedmo\Timestampable(on="create")
* #ORM\Column(type="datetime")
*/
private $created;
/**
* #var \DateTime $updated
*
* #Gedmo\Timestampable(on="update")
* #ORM\Column(type="datetime")
*/
private $updated;
My BitcoinBundle\Entity\BitcoinWallet is below:
<?php
namespace BitcoinBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity(repositoryClass="BitcoinBundle\Entity\BitcoinWalletRepository")
* #ORM\Table(name="bitcoin_wallet")
* #ORM\HasLifecycleCallbacks
*/
class BitcoinWallet
{
/**
* in use = The address is being used for some reason
* available = the address is free
*/
const STATE_IN_USE = 0;
const STATE_AVAILABLE = 1;
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #ORM\Column
* #ORM\GeneratedValue(strategy="NONE")
* #ORM\Column(type="string", length=34, unique=true)
*/
private $address;
/**
* #ORM\Column(name="state", type="smallint")
*/
private $state;
/**
* #ORM\Column(name="balance", type="decimal", precision=16, scale=8)
*/
private $balance = 0;
/**
* #ORM\Column(name="updated_at", type="datetime")
*/
private $updated_at;
After I run php bin/console doctrine:schema:update --force database was updated successfully, but now I am getting this message:
The target-entity BitcoinBundle\Entity\BitcoinWallet cannot be found in 'AppBundle\Entity\User#bitcoinWallet'.

Answer 1

It looks like entity declaration was incorrect.
In BitcoinBundle\Entity\BitcoinWallet should be ManyToOne statment:
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
* #ORM\ManyToOne(targetEntity="UserBundle\Entity\User", inversedBy="bitcoin_wallet")
*/
protected $id;
And ManyToOne statment in AppBundle\Entity\User.php is wrong one.
