php - Type error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, object given -
actually... more or less know problem. i'm receiving error in particular controller try persist($object)...
actually i'm developing webapp me have register books i'm reading.. , use google books api that. so, have next entities:
- admin
- users
- books
- categories
i thinking db , wanted table user_id, book_id decided manytomany but, don't know if way.. or not. (because familiars going use it)
it has many users can have same book , user can have many books obviusly.
so, error i'm getting guess it's because i'm not implementing done manytomany... write below controller , entities
where users like:
/** * @orm\entity * @orm\table(name="users") * @orm\entity(repositoryclass="usersrepository") * @uniqueentity("username") * @uniqueentity("email") */ class users implements userinterface, \serializable { /** * @orm\column(type="integer") * @orm\id * @orm\generatedvalue(strategy="auto") */ private $id; /** * @orm\column(type="text") * @assert\notblank() */ private $name; /** * @orm\column(type="text") * @assert\notblank() */ private $lastname; /** * @orm\column(type="text") * @assert\notblank() */ private $username; /** * @orm\column(type="string", length=255, unique=true) * @assert\notblank() * @assert\email() */ private $email; /** * * @assert\length(max=4096) */ private $plainpassword; /** * * @orm\column(type="string", length=64) */ private $password; /** * @orm\column(type="text") * @assert\notblank() */ private $language; /** * @orm\column(type="boolean") */ private $isactive; /***************** * users constructor. */ public function __construct() { $this->language = 'es'; $this->isactive = true; } /** * @return mixed */ public function getid() { return $this->id; } /** * @param mixed $id */ public function setid($id) { $this->id = $id; } /** * @return mixed */ public function getname() { return $this->name; } /** * @param mixed $name */ public function setname($name) { $this->name = $name; } /** * @return mixed */ public function getlastname() { return $this->lastname; } /** * @param mixed $lastname */ public function setlastname($lastname) { $this->lastname = $lastname; } /** * @return mixed */ public function getusername() { return $this->username; } /** * @param mixed $username */ public function setusername($username) { $this->username = $username; } /** * @return mixed */ public function getemail() { return $this->email; } /** * @param mixed $email */ public function setemail($email) { $this->email = $email; } /** * @return mixed */ public function getplainpassword() { return $this->plainpassword; } /** * @param mixed $plainpassword */ public function setplainpassword($plainpassword) { $this->plainpassword = $plainpassword; } /** * @return mixed */ public function getpassword() { return $this->password; } /** * @param mixed $password */ public function setpassword($password) { $this->password = $password; } /** * @return mixed */ public function getlanguage() { return $this->language; } /** * @param mixed $language */ public function setlanguage($language) { $this->language = $language; } /** * @return mixed */ public function getisactive() { return $this->isactive; } /** * @param mixed $isactive */ public function setisactive($isactive) { $this->isactive = $isactive; } //implementaciones de la interface public function getsalt() { // *may* need real salt depending on encoder // see section on salt below return null; } public function getroles() { return array('role_user'); } public function erasecredentials() { } /** @see \serializable::serialize() */ public function serialize() { return serialize(array( $this->id, $this->username, $this->password, $this->isactive, )); } /** @see \serializable::unserialize() */ public function unserialize($serialized) { list ( $this->id, $this->username, $this->password, $this->isactive, ) = unserialize($serialized); } } and books like:

any clue or solution?
thanks everyone! have nice day!

no $book->setusers($user); $book->adduser($user);
and, in general, method setusers not valid
public function setusers(users $users = null) { $this->users = $users; } you must not redefine property after being initialized in constructor. can add or remove elements it, assigning new value break doctrine's functionality.
