我正在开发一个基于Laravel 3的项目,我正在努力查看是否可以缩短处理关系的代码(更好的方法来执行以下操作)
用户控制器
$newUser = new User;
if($userData['organization'])
$newUser->organization = self::_professional('Organization', $newUser, $userData);
else
$newUser->school = self::_professional('School', $newUser ,$userData);
创建或检索学校/组织ID
private function _professional($type, $newUser, $userData)
{
if ( $orgId = $type::where('name', '=', $userData[strtolower($type)])->only('id'))
return $orgId;
else
{
try {
$org = $type::create(array('name' => $userData[strtolower($type)]));
return $org->attributes['id'];
} catch( Exception $e ) {
dd($e);
}
}
}
楷模
用户模型
class User extends Eloquent {
public function organization()
{
return $this->belongs_to('Organization');
}
public function school()
{
return $this->belongs_to('School');
}
}
组织/学校模式
class Organization extends Eloquent {
public function user()
{
return $this->has_many('User');
}
}
迁移
用户迁移
....
$table->integer('organization_id')->unsigned()->nullable();
$table->foreign('organization_id')->references('id')->on('organizations');
$table->integer('school_id')->unsigned()->nullable();
$table->foreign('school_id')->references('id')->on('schools');
....
组织/学校迁移
....
$table->increments('id');
$table->string('name');
$table->string('slug');
$table->integer('count')->default(1)->unsigned();
....
现在,我的问题是:
>有没有更好的方法来生成用户 – >学校/组织关系,那么上面使用的那个?如果是这样,怎么样?
>通过执行以下操作检索用户的学校/组织名称的更好方法:School :: find($schoolId) – > get()
做User :: find(1) – > school()不会检索学校的任何数据,只有:
[base:protected] => User Object
(
[attributes] => Array
(
[id] => 1
[nickname] => w0rldart
....
[organization_id] =>
[school_id] => 1
...
)
[relationships] => Array
(
)
[exists] => 1
[includes] => Array
(
)
)
[model] => School Object
(
[attributes] => Array
(
)
[original] => Array
(
)
[relationships] => Array
(
)
[exists] =>
[includes] => Array
(
)
)
解决方法:
// You have to save this before you can tied the organizations to it
$new_user->save();
// The organizations that you want to tie to your user
$oganization_ids = array(1, 2, 3);
// Save the organizations
$result = $new_user->organization()->sync($oganization_ids);
