You can not because reading a One2Many means getting all the values for
data integrity.

Of course, if you want just some (which means it is not really a
One2Many) the proper way is to use a relate action (searching on the
target model with the right domain and limit).

I thought that field was used to limit the number of records?

I didn't want to limit the number of child records. I wanted to limit the
number of id's returned in a model.x.read call.

It's ok though, I am no longer using the one2many field to get some ids'.

How can I see what the maximum number of id's a One2Many field returns?


Just specify size=… in the definition of the One2Many
