Hide group in xml form

[Richmond Fiko]

Hello,

I have a little noob question. In a form view, is it possible to hide a group with a condition for instance in:

<label name="is_insured"/>
<field name="is_insured"/>
<newline/>
<group string="Insurance Infos" id="statement_insurance_info">
<label name="insurance_part"/>
<field name="insurance_part"/>
<label name="insurance_number"/>
<field name="insurance_number"/>
<label name="party_insurance"/>
<field name="party_insurance"/>
</group>

group "Insurance infos" will be hide if is_insured (a bool field) is false and will appear if the field is set true.
If is it possible, how can I do it?
Thanks

Yes, you can. You must override view_attributes of the Model to return
the xpath that match the group and set a 'states' attribute with the
PYSON expression that will make 'invisible' state True.

Something like:

@classmethod
def view_attributes(cls):
# Hide the group when is_insured is not
# true
return [('//group[@id="statement_insurance_info"]', 'states', {
'invisible': Not(Bool(Eval('is_insured'))),
})]

You should always call super for modularity, otherwise it seems OK.
You could simplify the PYSON expression: ~Eval('is_insured')
