Hi all, I have some questions on table/attributes constraints, not sure if it is me I don't understand how they work or if they are issues. I would appreciate a clarification.
1) they seem to work while adding a new feature or when updating the attributes using feature form that opens using the identify tool, but not they do not work in the table of attributes both in table view or form view. Is this expected? 2) the "not null" constraint works if the attribute shows "NULL" while does not not if the cell is empty. While I understand the difference between NULL and empty, for the vast majority of users NULL=empty. Is this the intended behavior or is a bug? if it is the former than I would suggest add a "not empty" option 3) I have difficulties in understand how the "expression" and "expression description" work: if I choose a column for the former and fill the latter (that is optional) with some kind of text, then when reopening the vector properties I find the description in the "expression" and the column name in the "expression description". thanks in advance -- G -- _______________________________________________ QGIS-Developer mailing list [email protected] List info: https://lists.osgeo.org/mailman/listinfo/qgis-developer Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-developer
