Default values for a function field One2Many

[Jesús Martín Jiménez]

Hi,

I would like to add a One2Many field in a model without modifying the target model, so I'm trying to make this field as a funtional one. Now, I want to set the default values on each new record created through the setter method of this field, but seems that de default_field() method on a function field is not called. Is it correct? I'm missing something?

Thanks,

You can use the context[1] to pass a flag to check if you're creating
the target model from your One2Many field and override the default
function to get the value depending on the context.

It will be something like this:

lines = fields.One2Many(xxx, xxx, xxx,
context={'from_my_model': True})

and in the target model you will do:

@classmethod
def default_field(cls):
if 'from_my_model' in Transaction().context:
return your_value
return super(Class, cls).default_field()

default method should be called even for Function field.
But at which moment are you expecting the call?

When I make click over the new record icon of the one2many field.

Creating a new record in a one2many will not trigger the default value
of the one2many but the default values of the target Model.

Creating a new record in a one2many will not trigger the default value
of the one2many but the default values of the target Model.

Ok, thanks. I'll take it in account.
