THIS CODE RUN

def name_get(self):

def _name_get(d):

name = d.get('name', '')

identity_no = d.get('identity_no', '')

reg = '%s ( %s )' % (name, identity_no)

return (d['id'], reg)

result = list(map(_name_get, self.read(['name', 'identity_no'])))

return result

BUT I WANT GIVE A CONDITION LIKE THIS

@api.multi

def name_get(self):

if self.identity_no != False :

def _name_get(d):

name = d.get('name', '')

identity_no = d.get('identity_no', '')

reg = '%s ( %s )' % (name, identity_no)

return (d['id'], reg)

result = list(map(_name_get, self.read(['name', 'identity_no'])))

else :

def _name_get(d):

name = d.get('name', '')

return (d['id'], name)

result = list(map(_name_get, self.read(['name'])))

return result

ERROR :

Hello,

You can modify your code

@api.multi

def name_get(self):

for res in self:

if res.identity_no != False :

def _name_get(d):

name = d.get('name', '')

identity_no = d.get('identity_no', '')

reg = '%s ( %s )' % (name, identity_no)

return (d['id'], reg)

result = list(map(_name_get, res.read(['name', 'identity_no'])))

else :

def _name_get(d):

name = d.get('name', '')

return (d['id'], name)

result = list(map(_name_get, res.read(['name'])))

return result

Thanks

Just Break your method ..

def functionA(A)

def functionB(B):

if your condition:

self.functionA()

else:

self.functionA()
