DataTable ajax reload is not working

Question

I have tried various ways to reload my datatable after ajax query. However, it is just not working. I tried table.ajax.reload(), table.api().ajax.reload(), switch between datatable() and DataTable(). They are just not working.

$(document).ready(function() {
    var table = $('#organizationTable').DataTable();

    $(document).on('click', '.edit-modal', function() {
        $('.modal-title').text('Edit User');
        $('#id_edit').val($(this).data('id'));
        $('#first_name_edit').val($(this).data('first_name'));
        $('#last_name_edit').val($(this).data('last_name'));
        $('#email_edit').val($(this).data('email'));
        $('#user_role_edit').val($(this).data('role_id'));
        $('#user_status_edit').val($(this).data('status_id'));
        id = $('#id_edit').val();
        $('#editModal').modal('show');
    });

    $('.modal-footer').on('click', '.edit', function() {
        if ( $( ".required" ).val().length === 0 ) {

            // Usually show some kind of error message here

            // Prevent the form from submitting
            $('#editModal').modal('show');
            event.preventDefault();
        } else {
            $.ajax({
                type: 'PUT',
                url: '/users/' + id + '/update',
                data: {
                    'id': $("#id_edit").val(),
                    'first_name': $("#first_name_edit").val(),
                    'last_name': $("#last_name_edit").val(),
                    'email': $("#email_edit").val(),
                    'role_id': $("#user_role_edit").val(),
                    'status_id': $("#user_status_edit").val()
                },
                success: function(data) {
                    console.log(data);
                    table.ajax.reload();
                }
            });
        }

    });
} );

I have a piece of initiate code in the header too.

$( document ).ready(function() {
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
        },
        dataType: 'json'
    });
});

Answer 1

When I successfully update my form from AJax and reload the datatable, I will receive an error message saying DataTables warning: table id=organizationTable - Invalid JSON response. I think the reason is because I returned some data that doesn't match the format of my datatable. Is there a way that I can check the json format of my datatable? So, I can try to create an array that match the format for the updated user and return it as json format. Or I am looking into a wrong direction. Thank you guys.

Controller

public function update(Request $request, $id)
    {
        $user = User::find($id);

        request()->validate([
            'first_name' =>'required',
            'email' => ['required', Rule::unique('users')->ignore($user)],
        ]);

        $user->update($request->all());

        DB::table('model_has_roles')
            ->where('model_id', $user->id)
            ->update(['role_id' => $request->role_id]);

        $request->session()->flash('success', $user->first_name . ' is updated successfully.');

        return response()->json($user);
    }

DataTable View

JavaScript

$(document).ready(function() {

Answer 2

Piece of code which you have added in Question.

Doesn't contain your ajax url or Json in Datatable you are defining.

It should be something like this

$(document).ready(function() {
    var table = $('#organizationTable').DataTable({
        ajax: "https://api.myjson.com/bins/897v1",
    });


    $('#proces_input').on('click', function() {
        table.ajax.reload(); // reload
    });
});

You can refer more examples here

Answer 3

The correct way of reloading datatable is

$('#TableID').DataTable().ajax.reload();
