Two full functional QSqlRelationalTables, problem with adding a record
I'm writing a program for my mother which she can use to track the storage at her company.
For this I want to make a QDialog with two relational table models. In one model are the orders from the employees, which has a relation to the employee. In the other table the products that were ordered in that exact order. The order table is fully functional,
I can add orders and edit all the orders. The relation to the second model works too, if I select a order I get the appropriate products in the other model.
Now I'm trying to have a button that adds a product to the product model, but I can't it too work. The interpreter tells me:
edit: index was invalid
edit: editing failed
Also the new record does not show up on relational table model. When i look with a sqlite database manager the records have been added and the product_id is set to NULL as I want it.
Hope someone can help me get this working.
Code was too large for this forum, so you can find it here: http://pastebin.com/amQEpavB
