@JellyBool, 谢谢。我从How to use Transformer in one to many relationship. #1054找到了更好的解决方案。
先上代码：
DepartmentTransformer
class DepartmentTransformer extends TransformerAbstract
{
public function transform($department)
{
return [
'id' => $department['id'],
'name' => $department['name'],
'level' => $department['level'],
'parent_id' => $department['parent_id']
];
}
}
RolesTransformer
class RolesTransformer extends TransformerAbstract
{
public function transform($role)
{
return [
'name' => $role['name'],
'slug' => $role['slug'],
'description' => $role['description'],
'level' => $role['level']
];
}
}
UserTransformer
class UserTransformer extends TransformerAbstract
{
protected $defaultIncludes = ['departments','roles'];
public function transform($user)
{
return [
'id' => $user['id'],
'name' => $user['name'],
'email' => $user['email'],
'phone' => $user['phone'],
];
}
public function includeDepartments(User $user)
{
$dept = $user->departments;
return $this->collection($dept, new DepartmentTransformer());
}
public function includeRoles(User $user)
{
$rl = $user->roles;
return $this->collection($rl, new RolesTransformer());
}
}
然后，我在 Controller 里面调用
$user = User::where('email','=',$input['email'])->with('departments')->with('roles')->get();
return $this->response->collection($user, new UserTransformer());
得到如下返回
"data": {
{
"id": 43,
"name": "test7",
"email": "[email protected]",
"phone": "18679152257",
"departments": {
"data": {
{
"id": 1,
"name": "业务一部",
"level": 1,
"parent_id": 0
}
}
},
"roles": {
"data": {
{
"name": "agent",
"slug": "agent",
"description": "业务员",
"level": 1
}
}
}
}
}
