我正在研究laravel中的第一個項目,現在我執行搜索功能,但是,我正在做一個涉及多個左連接的查詢,並且在搜索時會返回一些冗餘信息。在laravel中執行此查詢的最佳方式是什麼?
相關的表是這四和查詢如下:
$searchData = ProfessionalDetail::select('u.id as user_id','u.first_name','u.last_name','u.profile_pic','c.name as city_name','professional_details.avg_ratings')
->join('users as u' , 'u.id', '=' ,'professional_details.user_id')
->join('user_speciality as us' , 'us.user_id', '=' ,'professional_details.user_id')
->join('specialities as sp' , 'sp.id', '=' ,'us.speciality_id')
->join('cities as c' , 'c.id', '=' ,'professional_details.city_id')
->join('users_roles as ur' , 'ur.user_id', '=' ,'professional_details.user_id')
->where(function ($q2) use ($name) {
$q2->where('u.first_name' , 'like', '%' . $name . '%')
->orWhere('u.last_name','like', '%'.$name.'%')
->orWhere('u.first_name','like',$name.'%');
->orWhere('sp.name','like',$name.'%');
})
->where('ur.role_id' ,'=' , 2)
->paginate($num_per_page);
return $searchData;[![demo][1]][1]
我試了一下,是用戶都列出來,通過名稱或專業(這是一個醫生頁面),當專業準備好時,一切進展順利。但是當我想按用戶列出時,有左連接'user_speciality'和'professional_details'。這使用戶無數次返回給我。
例如:
public function testApi(Request $request)
{
$users = ProfessionalDetail::searchByNameAndSpe("joshi", 10);
$i = 0;
if ($users) {
foreach ($users as $key => $value) {
$response["result"][] = $value;
$response["total"] = $i++;
}
} else {
return "error";
}
return $response;
}
返回:
{"result":[{"user_id":204,"first_name":"Joshi","last_name":"Mohit","profile_pic":"1495436016.jpg","name":"Skin Specialist","city_name":"Pune","avg_ratings":"0.00"},{"user_id":204,"first_name":"Joshi","last_name":"Mohit","profile_pic":"1495436016.jpg","name":"Heart Specialist","city_name":"Pune","avg_ratings":"0.00"},{"user_id":204,"first_name":"Joshi","last_name":"Mohit","profile_pic":"1495436016.jpg","name":"ENT Specialist","city_name":"Pune","avg_ratings":"0.00"},{"user_id":204,"first_name":"Joshi","last_name":"Mohit","profile_pic":"1495436016.jpg","name":"Kidney Specialist","city_name":"Pune","avg_ratings":"0.00"},{"user_id":204,"first_name":"Joshi","last_name":"Mohit","profile_pic":"1495436016.jpg","name":"Eye Specialist","city_name":"Pune","avg_ratings":"0.00"}],"total":4}
喬希只能註冊一次,但是我知道他會因關係「多對多」,因爲他返回了無數次擁有幾個專業。現在
,要得到它的專業和用戶的名稱進行搜索,我所知道的唯一的辦法就是使用左加入,我想辦法給信息分離將被處理的信息但是II想知道這是否可以在查詢中解決,因爲我對SQL不太瞭解,如果有什麼辦法,我會非常感激,因爲它會爲我節省很多調試步驟所有的信息。
每個模型的方法
UserSpeciality表
public function users() {
return $this->belongsToMany('App\User', 'user_speciality', 'speciality_id', 'user_id');
}
用戶
public function userSpeciality() {
return $this->belongsToMany('App\Speciality','user_speciality', 'user_id', 'speciality_id');
}
專業
public function users() {
return $this->belongsToMany('App\User', 'user_speciality', 'user_id', 'speciality_id');
}
ProfesionalDetail表
public function user(){
return $this->belongsTo("App\User");
}
你有模型建立這些表? –
如果和每一個都有其相應的關係方法, 我修改了帖子並添加了他們 –
