Update a one2many field

[Christophe (net)]

Hello

I try to update a value in a one2many through the on_change_* method.
I saw that it was possible to use the form:
{O2M: {'update': [{field: value, ...}]}}
but the latter does not update the records currently displayed in the
client and it is not possible to achieve in particular recording.
Is there a better way?

Regards

Since the 3.4 version (I think), you do not have to return anything in on_change methods (NOT true

for on_change_with methods). Juste update the values of your field, and reset it to make sure it

is detected as modified :

def on_change_...(self):

    self.lines[0].name = 'some new name'

    # Force modification detection

    self.lines = self.lines

That's all !

You have to return the id in the dict values in order to the client know
which record you want to update. So it will be:

{O2M: {'update': [{'id': record_id, field: value, ...}]}}

Hope it helps!

It's difficult to provide a more complete example without the model
definition.

Could you explain what are you trying and what problems do you have?
Could you share your model definition?
