Optimal way to search columns from joined tables in yajra datatable - laravel

Question

I am using yajra datatable in a laravel project to generate a list. My problem is: when I join a table and try to use a raw query to extract a column, it becomes unsearchable.
My table code:
$AAEListData = Entrepreneur::leftjoin('users', 'users.id', 'entrepreneurs.user_id')
->where('entrepreneurs.user_id', Auth::user()->id)
->groupBy('entrepreneurs.id')
->orderBy('entrepreneurs.created_at','desc')
->select([
'entrepreneurs.*',
'users.id as user',
DB::raw('CONCAT(IFNULL(users.user_first_name,"")," ",IFNULL(users.user_middle_name,"")," ",IFNULL(users.user_last_name,"")) as user_name')
]);
return Datatables::of($AAEListData)
->addColumn('action', function ($AAEListData) {
$view_btn = '<a href="' . url('entrepreneur/advance-against-expense-info/edit/' . Encryption::encodeId($AAEListData->id)) .
'" class="btn btn-xs btn-primary open" target="_blank" ><i class="fa fa-folder-open"></i> Open</a>';
return $view_btn;
})
->rawColumns(['action'])
->make(true);
The problem starts with the column user_name.
columns: [
{data: 'name', name: 'name'},
{data: 'phone', name: 'phone'},
{data: 'status', name: 'status'},
{data: 'user_name', name: 'user_name'},
{data: 'action', name: 'action'},
],
Whenever I try to search something, an error says column entrepreneurs.user_name not found. That is because it is not in that table, it comes from a joined table users. Can yajra datatable not detect this? I have searched this issue on the net and most suggestions ask converting the query collection to an array or simple avoid DB::RAW altogether. Neither solution is optimal for my situation but I am willing to do it the hard way if no other choice remains. My question is: is there a simpler way of informing datatable about which column belongs in which table?
N.B: no, simply doing users.user_name does not work. That is the first thing I tried, in both controller and blade, neither worked.

Answer 1

If your using the latest version you should define the name: table.column pattern.

Answer 2

I think your problem is not about Yajra. "name: table.column" pattern is working to me("yajra/laravel-datatables-oracle": "^9.19").
I guess there is no column of user_name in tables of users and entrepreneurs.
it won't work below.
SELECT CONCAT(IFNULL(users.user_first_name,"")," ",IFNULL(users.user_middle_name,"")," ",IFNULL(users.user_last_name,"")) as user_name
FROM USERS
WHERE user_name = [userName];
You should make a subquery.
SELECT
t1.*,
users.id as user,
FROM
(SELECT entrepreneurs.*,
CONCAT(IFNULL(users.user_first_name,"")," ",IFNULL(users.user_middle_name,"")," ",IFNULL(users.user_last_name,"")) as user_name
FROM entrepreneurs
WHERE entrepreneurs.user_id = Auth::user()->id
) as t1
LEFT JOIN users on users.id = t1.user_id
WHERE t1.user_name = [userName]
GROUP By t1.id
----> Yajra subquery example
"name: table.column" pattern
Blade
columns: [
{ data: 'delivery_type', name: 't2.delivery_type' },
],
Controller
if ($userType == 'HFF0601' || $userType == 'HFF0602') {
$defaultQuery =
datatables()->of(Delivery::select([
'deliveries.*',
'deliveries.status as status_code',
't1.email',
't1.user_type',
't2.group_no',
't2.delivery_type',
't2.delivery_type as delivery_type_code'
])->join('delivery_groups AS t2', 'deliveries.grp_id', '=', 't2.id')
->leftJoin('users AS t1', 'deliveries.user_id', '=', 't1.id'));
}
return $defaultQuery
->filter(function ($query) use ($request) {
.
.
.

I tested my code and it works. but the concat in the where statement may have performance issues.
DB::raw("CONCAT(t1.name,' ',t1.last_name) as fullname")
->orWhereRaw("CONCAT(t1.name,' ',t1.last_name) like ?", "%{$serchTerms}%")
{ data: 'fullname', name: 'fullname' },
if ($userType == 'HFF0601' || $userType == 'HFF0602') {
$defaultQuery = datatables()
->of(Delivery::select(
[DB::raw("CONCAT(t1.name,' ',t1.last_name) as fullname"),
'deliveries.*',
'deliveries.status as status_code',
't1.email',
't1.user_type',
't2.group_no',
't2.delivery_type',
't2.delivery_type as delivery_type_code'])
->join('delivery_groups AS t2', 'deliveries.grp_id', '=', 't2.id')
->leftJoin('users AS t1', 'deliveries.user_id', '=', 't1.id'));
}
return $defaultQuery
->filter(function ($query) use ($request) {
//Filtering date range
//...
//Global Search
if ($request->has('searchterms')) {
$serchTerms = $request->searchterms;
$query->where(function($q) use($serchTerms) {
$q->where('shipping_no', 'like', "%{$serchTerms}%")
->orWhere('order_no', 'like', "%{$serchTerms}%")
->orWhere('email', 'like', "%{$serchTerms}%")
->orWhereRaw("CONCAT(t1.name,' ',t1.last_name) like ?", "%{$serchTerms}%")
->orWhere('from_name', 'like', "%{$serchTerms}%")
->orWhere('to_name', 'like', "%{$serchTerms}%")
->orWhere('desc1', 'like', "%{$serchTerms}%")
->orWhere('status', 'like', "%{$serchTerms}%");
});
}
})
columns: [
{ data: 'checkbox', name: 'checkbox', orderable: false, searchable: false},
{ data: 'id', name: 'id' },
{ data: 'group_no', name: 'group_no' },
{ data: 'delivery_type', name: 't2.delivery_type' },
{ data: 'user_id', name: 'user_id' },
{ data: 'email', name: 'email' },
{ data: 'order_no', name: 'order_no' },
