Yarja Datatables - getting results for specific id - laravel

Question

I am trying to have the ability for the user to click on a link and get jobs for a specific operative. As a test I am only using three field from a job table
id,operative_id,address
The operative ID is the parameter I wish to pass to the datatable ajax controller.
The operative ID is sent by the jobs controller to a blade template in the normal manner. I then have a table area:
<table class="table data-table" id="thetable">
<thead>
<th>id</th>
<th>address</th>
<th>operative id</th>
<th></th>
</thead>
<tbody>
</tbody>
</table>
In the javascript area of the blade template I have
<script type="text/javascript">
$(function () {
var table = $('.data-table').DataTable({
"iDisplayLength": 25,
"lengthMenu": [ [10, 25, 50,100,200, -1], [10, 25, 50,100,200, "All"] ],
columnDefs: [
{
targets: -1,
className: 'dt-right'
}],
processing: true,
serverSide: true,
ajax:"{{route('testData',['id' => $id])}}",
columns: [
{ data: 'jobID', name: 'jobID' , orderable: false, searchable: false},
{data: 'address', name: 'address'},
{data: 'operative_id', name: 'operative' },
{data: 'action', name: 'action', orderable: false, searchable: false},
],
});
});
</script>
In my controller I have this function:
public function testData (Request $request, $id)
{
$jb = DB::table('job')
->select('id AS jobID','operative_id','address')->where('operative_id',$id)->get();
return Datatables::of($jb)
->addColumn('action', function($pubs){
$btn = '<div style="float:right">
<i class="fas fa-book" ></i><i class="fas fa-edit" ></i></div>';
return $btn;
})
->make(true);
}
The controller (DatatablesController) has other functions that work perfectly and are much more complex, but I only want to show the jobs of the $id passed in. The error I am getting is a 500 error
Class App\Http\Controllers\DataTablesController does not exist
which of course it does.
For example this works perfectly:
public function allJobs(Request $request)
{
$user = Auth::user();
$cl = $user->client_id;
$jb = DB::table('job')
->join('job_status', 'job.jobStatus_id', '=', 'job_status.id')
->join('customers', 'job.customer_id', '=', 'customers.id')
->join('users', 'job.operative_id', 'users.id')
->where('job.client_id', $cl)
->select(['job.id as id', 'job_status.status as status', 'job.customer_id as customer_id', 'customers.customer as customer', 'users.name as operative','job.address as address','job.postcode as postcode','job.slug as slug','job_status.id as jobStatusID'])
->get();
return Datatables::of($jb)
->addColumn('action', function($pubs){
$btn = '<div style="float:right">
<i class="fas fa-book" ></i><i class="fas fa-edit" ></i></div>';
return $btn;
})
->make(true);
}
The route is defined as
Route::get('testData/{id}','DataTablesController#testData')->name('testData');
I just cannot see the way around it. Help is greatly appreciated!

Answer 1

I have worked it out. Basically the route cannot contain a parameter, so the {id} is dropped.
I placed a drop down box above the table and amended the javascript to
ajax:{
"url": "{{ route('allJobsData') }}",
"data": function(d) {
d.operativeChoice = $('#operativeChoice').val();
}
So if there is value in the select box this is sent via the ajax request to the controller. It is then just a case of playing with the controller code with an if statement.
