Delete not working?

[AllTerrainDeveloper]

When I delete a row, the row disappears from the view, but it is still present in the data source. So when pushing data to server (with source.getAll()), anything has changed.

I am using internal mode, and also, no event is raised when I try to delete it.
On settings i have
delete.confirmDelete = true;

on html:
(deleteConfirm)="onDeleteConfirm($event)"

on ts:

onDeleteConfirm(event) {
    if (window.confirm('Are you sure you want to save?')) {
      //call to remote api, remember that you have to await this
      event.confirm.resolve(event.newData);
    } else {
      event.confirm.reject();
    }
  }

but it is never called...

Checked everything already in the docs:
https://akveo.github.io/ng2-smart-table/#/documentation

Any ideas?

did you try to call the load method?

[AllTerrainDeveloper]

What do you mean by calling hte load method? I load data, then I remove a row, and load old data? I don't get it. Can you elaborate please?

[vicenthy]

I think that you did could manually update with refresh method or load method

why pushing all the data to the server?
when the delete method is called the just send the id deleted to the backend

There seems to be condition issue at https://github.com/akveo/ng2-smart-table/blob/master/projects/ng2-smart-table/src/lib/lib/data-source/local/local.data-source.ts#L50

For now, here is a hack that should work.

// smart-table config
{
        ...
        actions: {
          delete: true,
          ...
        },
        delete: {
          deleteButtonContent: 'Delete',
          confirmDelete: true
        },
        columns: {...}
}

// define deleteConfirm in element
<ng2-smart-table 
	...
	[settings]="config" 
	[source]="value"
	(deleteConfirm)="onDeleteConfirm($event)"
/>

// write onDeleteConfirm like below
public onDeleteConfirm(event) {
    this.value = event.source.data.filter((d: any) => !isEqual(d, event.data));
    event.confirm.resolve();
  }

isEqual is a lodash function that deep compares both the object.

In short, remove the element urself using the datasource.
