[英]How to calculate and display ratings for font-awesome using jQuery
[英]How to get average ratings in laravel using jquery
我有兩個表用戶和評分,一個用戶可以給顧問評分,我的評分表如下所示
User_id | consultant_id | rating
---------------------------------
1 1 2
---------------------------------
2 1 3
---------------------------------
3 1 1
---------------------------------
4 1 1
這是我的桌子的樣子
我的控制器:
public function searchConsultants(Request $request)
{
$location = $request->get('location');
$data = Consultant::where('location','LIKE','%'.$location.'%')->with('ratings')->get();
return response()->json($data);
}
響應Im從searchConsultants方法獲取
[{"id":1,"cunsultant_name":"Manjunath Mj",
"contact_number":"9035206471",
"location":"Delhi",
"department_id":1,09:00:51",
"ratings":[{
"id":1,"customer_id":1,"consultant_id":1,"rating":4,
"id":2,"customer_id":2,"consultant_id":1,"rating":2,
"id":3,"customer_id":3,"consultant_id":1,"rating":1,
"id":4,"customer_id":4,"consultant_id":1,"rating":5,
}]
}]
我正在使用ajax get方法來顯示數據,這是我的js文件
$.each(data, function(index) {
str +="<tr><td>"+data[index].id+"</td>
<td>"+data[index].cunsultant_name+"</td>
<td>"+data[index].contact_number+"</td>
<td>"+data[index].ratings[index].rating_for_manager+"</td><td>"+data[index].location+"</td></tr>";
});
當我單擊搜索顧問按鈕時,我應該獲得具有平均評分的顧問詳細信息。
您可以在Controller的searchConsultants方法中從查詢中獲得平均評級。
將查詢更改為此(這應為您提供與搜索條件匹配的每個顧問的平均評分):
$ data =顧問::: select('consultants。*',DB :: raw('avg(rating)'))
- >其中(。 '位置', 'LIKE', '%' $位置 '%')
->加入('ratings','ratings。consultant_id','=','consultants.id')
- > GROUPBY( 'consultant_id') - >獲得();
