美好的一天。我想在数据表中显示我的数据,但我遇到了错误并在数组上调用了成员函数getQuery()。
Iámnew到laravel和这个yajra图书馆。希望有人可以帮我解决这个错误。
这是我的ajax。它会将level_id和level传递给我的控制器,然后返回查询结果(如果匹配)。
//GENERAL
var $i=0;
var level_id = '{{ @$level->id }}';
var level = '{{ @$_level }}';
var viewStudent
function view_students($this){
viewStudent
if ($('#viewStudent-div').is(':hidden')) {
$(".sidebar .menus").removeClass("active");
$($this).addClass("active");
$('#viewStudent-div').siblings().hide('slow/400/fast', function() {
$('#viewStudent-div').show('slow/400/fast');
});
}
}
$(function(){
viewStudent = $('#viewStudent-table').DataTable({
order: [[ 0, "asc" ]],
Language: {
sLoadingRecords:"<img src='{{asset('assets/images/load.gif')}}' style='max-height:30px;'/> Fetching data...",
sEmptyTable: "No data available"
},
ajax:{
url:'{{ route("json_product_user") }}',
data: function (d) {
d.level_id = level_id;
d.level = level;
}
},
columnDefs: [
{
targets: 0,
searchable:false,
orderable:false,
},
],
columns:[
{
data: "full_name",
render: function(data, type, row){
return data;
}
},
{
data: "product_name",
render: function(data, type, row){
var html = '';
html += '<p style="">'+data+'</p>';
return html;
}
},
{
data: "level",
render: function(data, type, row){
return data;
}
},
{
data: "date_purchase",
render: function(data, type, row){
var html = '';
html += '<p style="text-align: center">'+moment(data).format('MMM-DD-YYYY')+'</p>';
return html;
}
}
]
});
});
这是我的控制器
public function viewStudents(Request $request)
{
if( $request->has('level_id') ){
if($request->level == 'school') {
$query = DB::table('product_user')
->leftJoin('products', 'product_user.product_id', '=', 'products.id')
->leftJoin('school_products', 'product_user.product_id', '=', 'school_products.product_id')
->leftJoin('users', 'product_user.user_id', '=', 'users.id')
->whereRaw("school_products.school_id = " . $request->level_id . " OR products.organization_id = ".$org_id)
->select('products.name as product_name', DB::raw('CONCAT(users.last_name, ", ", users.first_name ) AS full_name'), 'product_user.created_at', 'products.level as level')
->get();
}
else{
$query= DB::table('product_user')
->leftJoin('products', 'product_user.product_id', '=', 'products.id')
->leftJoin('school_products', 'product_user.product_id', '=', 'school_products.product_id')
->leftJoin('users', 'product_user.user_id', '=', 'users.id')
->whereRaw("products.level = 'organization' AND products.organization_id = ".$request->level_id)
->select('products.name as product_name', DB::raw('CONCAT(users.last_name, ", ", users.first_name ) AS full_name'), 'product_user.created_at', 'products.level as level')
->get();
}
}
// return $query;
return Datatables::of($query)->make(true);
}
答案 0 :(得分:0)
我相信因为你使用的是DB,所以DB select的返回类型是一个普通对象数组(stdClass)。在这种情况下,您必须使用
将输出转换为\ Illuminate \ Support \ Collection$collection = new \Illuminate\Support\Collection($query);
return Datatables::of($collection)->make(true);
或
$collection = collect($query);
return Datatables::of($collection)->make(true);
collect()在laravel 5.3中为我工作。请看一下这个答案: https://github.com/laravel/docs/issues/2867#issuecomment-343664438
