How to edit your project data via WFS

When an external GIS application supports WFS-T (transaction operation), it is possible to edit the data in a project in a GIS.

It is currently possible to edit geometries and attributes and add new features. It is not possible to remove features.

How to edit project data via WFS in QGIS:

First follow the steps to add a WFS by following: How to access your project's WFS in QGIS.
Select the layer you want to edit in the layer box.
Click on the pen button to enable/disable the edit mode of the select layer.
Click on the polygon with start button to create a new feature.
Click multiple times to create a polygon.
Right click to finalize the polygon and provide attributes for your new feature.
Make sure you at least provide a new name for your feature.
Click on the Save button to commit your changes. The data will now be updated in the Tygron Platform.
Click on the pen button to disable the edit mode
Select the layer, and refresh it (Press F5) to obtain all adjusted items in QGIS. (For example: neighborhoods cannot overlap, and buildings cannot overlap.)

Notes

You can only edit items while your project's session is active.
Editing items does not work if your project is in a test run
When using a WFS endpoint which only displays partial data (such as the ROADS endpoint for buildings), any submitted modification must still be valid across all data. I.e., even if you can't see other buildings in your GIS application, the modified roads are not allowed to intersect with other buildings in the project in the Tygron Platform.
