我有Laravel Eloquent class Collage
class Collage extends Model
{
/**
* Get the User that owns this Collage.
*/
public function user()
{
return $this->belongsTo('App'User');
}
}
拼贴迁移模式
Schema::create('collages', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->string('name')->nullable();
$table->timestamps();
});
和User
class User extends Authenticatable
{
/**
* Get all Collages that belongs to this User.
*/
public function collages()
{
return $this->hasMany('App'Collage');
}
}
但是当我在tinker
上这样做时$user = App'User::find(1)->first();
$collage = new App'Collage;
$collage->name = 'Collage';
$collage->user = $user;
//and save
$collage->save();
抛出错误QueryException
General error: 1 table collages has no column named user
变化
$collage->user = $user
$collage->user_id = $user->id
更新模式以建立关系，
Schema::create('collages', function (Blueprint $table) {
$table->increments('id');
$table->integer('user_id')->unsigned();
$table->foreign('user_id')->references('id')->on('users');
$table->string('name')->nullable();
$table->timestamps();
});
这样Laravel Eloquent就会自动引用关系。
