rowReorder - can i send dragged row id?

paweltrela

Hello,

I am using rowReorder and everything works fine.
I just would like to know.

Is it possible to send row which i dragged through the API edit call?
My ajax endpoints looks like this and i am passing there some custom params.
Is there way to add there some parameter with dragged row?

I know that when i use rowReorder it sends my all row params, but i need directly row which i dragged.

            ajax: {
                create: {
                    type: "POST",
                    url: '<%= path %>',
                    data: function ( d ) {
                        d.board_id = '<%= @board.id %>';
                        d.user_id = <%= current_user.id %>;
                    }
                },
                edit: {
                    type: "PATCH",
                    url: '<%= path %>'+"/_id_",
                    data: function ( d ) {
                        d.board_id = '<%= @board.id %>';
                        d.user_id = <%= current_user.id %>;
                    }
                },
                remove: {
                    type: "DELETE",
                    url: '<%= path %>'+"/_id_",
                    data: function ( d ) {
                        d.board_id = '<%= @board.id %>';
                    }
                }
            },

This example shows how to setup RowReorder with Editor.

@kthorngren yes, i know but everything in my case works fine.
When i move my row, all rows involved in this process are sent to backend.

But my backend doesn't know which row was directly dragged and moved.
All rows are 'asc' ordered.

I need to know which row was clicked by the user and dragged into another place

I believe you can use the row-reorder event for that information. The detail parameter has a node object which I believe is the dragged row.

@kthorngren, thank you, i've checked it and it was row-reorder event.

When i use:

        .on( 'row-reorder', function ( e, diff, edit ) {
            console.log(edit.triggerRow.data().DT_RowId);
        });

i receive an id of the row i clicked.

But is there easy way to send it to the backend like a normal parameter within an edit ajax call?
The only way i am thinking now is just pass it to the session parameters and call it on the backend side.

Possibly you can use the Editor's preSubmit event to add the row_id. I'm guessing it follows after the row-reorder event. Not sure without testing though.
