hr.attendance: extend data model with value for break
Hi to all,
I'd like to extend the hr.attendance data model to manage a default break per day. So I switched to developer mode, then went to "technical" -> "data models" found hr.attendance model and added a float number field x_break. I also modified the corresponding view so that this field is shown. Now, how can I achieve, that this field carries a value of, for instance, 0.75 by default? The field should be editable but if no one edits, it should be 0.75. How can I do it?
And, as a second step, I would like to have another field that shows the difference between worked_hours and this break. I think that this shoul be a calculated field. In the field definition I see a textbox "compute". Do I simply write down "worked_hours - x_break" in this textbox?
