 | |
|      * - A 'soft deletion' is if the point is not deleted, but the tagging is modified which will result in the point not being picked up by the filters anymore.
 | |
|      *    Apart having needing theme-specific tags added (which must be supplied by the theme creator), fixme='marked for deletion' will be added too
 | |
|      *
 | |
|      * A deletion is only possible if the user is logged in.
 | |
|      * A soft deletion is only possible if tags are provided
 | |
|      * A hard deletion is only possible if the user has sufficient rigts
 | |
|      *
 | |
|      * There is also the possibility to have a 'trojan horse' option. If the user selects that option, it is NEVER removed, but the tags are applied.
 | |
|      * Ideal for the case of "THIS PATH IS ON MY GROUND AND SHOULD BE DELETED IMMEDIATELY OR I WILL GET MY LAWYER" but to mark it as private instead.
 | |
|      * (Note that _delete_reason is used as trigger to do actual deletion - setting such a tag WILL delete from the database with that as changeset comment)

 | |
|      * @param state: the state of the application
 | |
|      * @param options softDeletionTags: the tags to apply if the user doesn't have permission to delete, e.g. 'disused:amenity=public_bookcase', 'amenity='. After applying, the element should not be picked up on the map anymore. If undefined, the wizard will only show up if the point can be (hard) deleted
