Hello,
Could anyone give me a brief, clear example of how to have a calculated field ?
I' m trying to have my first calculated field
I have 2 Date fields and I want my calculated field to be the difference in
days between the 2 dates
How do I set that ?
The documentation says that "on_change" is an attribute of the filed, like this
Field.on_change
Does this mean that I should write this ?
fields.Numeric('duration', digits=(2,), on_change=someDatefield) ?
Can I trust the documentation on this ?
In the code of the sale.sale model, on_change is not used like that, but it' s
quite complicated and I' ma bit overwhelmed
Thanks in advance
