我知道这个问题已被提出,但我仍然无法找到我做错的事.
原文链接:/laravel/134682.html我正在使用Laravel框架.
我有2个表(用户和位置).当我想创建一个用户时,我收到错误消息:
sqlSTATE[23000]: Integrity constraint violation: 1452 Cannot add or
update a child row: a foreign key constraint fails
(festival_aid
.users
,CONSTRAINTfk_users_locations1
FOREIGN KEY
(location_id
) REFERENCESlocations
(location_id
) ON DELETE
CASCADE ON UPDATE NO ACTION) (sql: insert intousers
(user_id
,
user_email
,location_id
) values (?,?,?)) (Bindings: array ( 0 =>
‘1’,1 => ‘test@hotmail.com’,2 => ‘1’,))
表用户
CREATE TABLE IF NOT EXISTS `festival_aid`.`users` ( `user_id` BIGINT NOT NULL AUTO_INCREMENT,`user_email` VARCHAR(45) NOT NULL,`user_created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,`user_modified` TIMESTAMP NULL,`user_deleted` TIMESTAMP NULL,`user_lastlogin` TIMESTAMP NULL,`user_locked` TIMESTAMP NULL,`location_id` BIGINT NOT NULL,PRIMARY KEY (`user_id`),UNIQUE INDEX `user_email_UNIQUE` (`user_email` ASC),CONSTRAINT `fk_users_locations1` FOREIGN KEY (`location_id`) REFERENCES `festival_aid`.`locations` (`location_id`) ON DELETE CASCADE ON UPDATE NO ACTION,ENGINE = InnoDB;
表位置
DROP TABLE IF EXISTS `festival_aid`.`locations` ; CREATE TABLE IF NOT EXISTS `festival_aid`.`locations` ( `location_id` BIGINT NOT NULL AUTO_INCREMENT,`location_latitude` FLOAT NOT NULL,`location_longitude` FLOAT NOT NULL,`location_desc` VARCHAR(255) NULL,`location_type` VARCHAR(45) NULL,PRIMARY KEY (`location_id`)) ENGINE = InnoDB;
迁移用户
public function up() { Schema::table('users',function(Blueprint $table) { $table->increments('user_id'); $table->string('user_email'); $table->timestamp('user_created'); $table->timestamp('user_modified'); $table->timestamp('user_deleted'); $table->timestamp('user_lastlogin'); $table->timestamp('user_locked'); $table->foreign('location_id') ->references('id')->on('locations'); //->onDelete('cascade'); }); }
迁移地点
public function up() { Schema::table('locations',function(Blueprint $table) { $table->primary('location_id'); $table->float('location_latitude'); $table->float('location_longitude'); $table->string('location_desc'); $table->string('location_type'); }); }
模型用户
public function location() { return $this->belongsTo('Location'); }
型号位置
public function user() { return $this->hasOne('User'); }
调节器
public function store() { $input = Input::all(); $rules = array('user_email' => 'required|unique:users|email'); $v = Validator::make($input,$rules); if($v->passes()) { $user = new User(); $location = new Location(); $user->user_email = $input['user_email']; //$user->location_id = $input['location_id']; $location->location_latitude = $input['location_latitude']; $location->location_longitude = $input['location_longitude']; $user->save(); $location->save(); }
我似乎无法找到我做错的事.显然外键有问题.
