Fetch associated permissions for a row with ajax

[Padmore51]

I am using laravel 4.2 on a project and i need the permissions checkboxes to be checked when i want to edit a role. this is html code `

Permissions

                            <div class="col-sm-10">
                                @foreach($permissions as $permission )
                                    <div class="checkbox">
                                        <label>
                                            <input {{isset($editrole)&&array_key_exists($permission->name,$editrole) ?'checked': ''}} {{isset($permission_role[$permission->name])&&$permission_role[$permission->name]==1?'checked':''}} type="checkbox" name="permissionname[]" id="{{{$permission->name}}}" value="{{$permission->name}}" class="flat">  {{$permission->display_name}}
                                        </label>
                                    </div>

                                @endforeach
                            </div>
                        </div>

` the associated permission checkboxes should be checked when i select a row.

below is the ajax script $(document).on('click', '#permisson_edit', function(){ var actionurl = '<?php echo URL::route('setup.roles') ?>'; row = $(this).closest('tr'); cols = row.find('td');

        $.ajax({
            url: actionurl,
            type: 'get',
            dataType: 'json',
            data: {'id': row.data('id')},            
            success: function (data) {
                $('#id').val(data.id);
                $('#name').val(data.name)
                $('#display_name').val(data.display_name)
                $('#permissionname').val(data.permissionname)
                $('.role_modal').modal('toggle');
            },
            error: function (e) {
                console.log(e)
            }

        });
    })

my controller only returns the roles. return Response::json($roles);

How can i return the one to many relationship on roles and permissions?? How do i create that relationship in the first place? Then how will those checkboxes be checked?
