What data structure does one2many fields have, when they are passed as arguments in onchange method?

Question

Something like:

def onchange_my_o2m(self, cr, uid, o2m_field):
....< How to access "o2m_field[0].name", e.g.?>
return result

What is the structure of the o2m_field in the onchange method?

I first thought it's just a list of ids. But that turned out to be false. And it's certainly not a list of browse_record objects...

I'm currently assuming that it is a list of tuples... [(ID, {field1: ..}), ... ]

Thanks for your help.

Try the below code:-

def onchange_my_o2m(self, cr, uid, o2m_field):
if o2m_field:
for o2m_value in o2m_field:
if o2m_value is dict and 'name' in o2m_value.keys():
print o2m_value['name']
return result
