I propose to you this code, it works even for nested attributes like for
example get_value_of("a_relation.another_relation.some_field","default value if
not found")
<code>
Class SomeModel(Entity):
def get_values(self,attrs):
return [self.get_value_of(attr) for attr in attrs]
def get_value_of(self,attr,default=""):
"""
"""
path = attr.split(".")
inst = self
for node in path :
inst = getattr(inst,node,None)
if inst == None:
inst = default
break
return inst
</code>
Hope this helps.
