我目前正在使用AngularJs制作Yii2 RESTful系统.
在我的数据库中,我有几个列,我希望能够从我系统中的某个点进行特定调用时返回.
我遇到的问题是如何从系统另一部分的restful调用中返回少量字段,例如(id,title和stub),以便忽略表中的其他字段.
理想情况下,我喜欢它以类似于模型规则如何与yii中的场景一起工作的方式工作.
解决方法
我认为有两种方法：
1.使用params
// returns all fields as declared in fields() http://localhost/users // only returns field id and email,provided they are declared in fields() http://localhost/users?fields=id,email // returns all fields in fields() and field profile if it is in extraFields() http://localhost/users?expand=profile // only returns field id,email and profile,provided they are in fields() and extraFields() http://localhost/users?fields=id,email&expand=profile
2.覆盖模型的字段()
// explicitly list every field,best used when you want to make sure the changes
// in your DB table or model attributes do not cause your field changes (to keep API backward compatibility).
public function fields()
{
return [
// field name is the same as the attribute name
'id',// field name is "email",the corresponding attribute name is "email_address"
'email' => 'email_address',// field name is "name",its value is defined by a PHP callback
'name' => function () {
return $this->first_name . ' ' . $this->last_name;
},];
}
// filter out some fields,best used when you want to inherit the parent implementation
// and blacklist some sensitive fields.
public function fields()
{
$fields = parent::fields();
// remove fields that contain sensitive information
unset($fields['auth_key'],$fields['password_hash'],$fields['password_reset_token']);
return $fields;
}
