Thank you Cedric for your comments. I have just tried but it doesn't work. Maybe because i missed something else. At least i know i am on the right direction based on your comment. I just want to mention by some details as i thought maybe i wasn't able to explain it correctly.
class model1()
_name='company.model1'
*multiprice *= fields.Boolean("Multi Price allowed?
mod2 = fields.one2many(model2 ...etc...)
class model2()
_name='company.model2'
mod1ref = fields.many2one(model1 , ...etc...)
mod3 = fields.one2many(model3 .... etc ...)
class model3()
mod2ref = fields.many2one(model1, ...etc,....)
FF = fields.Boolean("FF" , states=STATES)
STATES = {
'invisible' : Bool(Eval('_parent_model1.*multiprice*')),
}
Actually i want to make this field invisible based on the value from parent
of his parent.
I tried the sample code it seems that it always return "True" value.
As i tested before, Even if i put some loblob instead of multi price. It
also returns True.
Just to ask whether this is because of some small tips, For example i'm
writing classless in different files (.py).
was it the cause of such problems ?
I have been spending an entire of the last week to find a solution for this
simple looking problem by reviewing docs and codes of other modules. [?]
Thanks,
