How to group and aggregate in a view?
I have defined a model similar to the following:
name: char
group: many2one
qty: float
performance: function(float)
I would like to show view displaying group, qty and performance. But the group may be repeated for different records. So, I want to show every group only once, summing qty and performance (which is a function field).
I don´t what to show expandable groups. Just, one line per group.
