Hi, I'm building several products that need to share several common attributes and methods, so I put those is a product ('Master') that the other products subclass. My problem is that I can't figure out how to call methods in the Master class and how to access its attributes. Very simplified, it looks something like this: class Master: def __init__(self, status, REQUEST=None): """Initialize a new master object""" self.status = status def manage_edit(self, status, REQUEST=None): """Change object properties""" self.status = status def Visible(self): """Check if object's status is 'visible'""" if self.status == 4: return 1 return 0 from Products.Master import Master class Foo(Master): meta_type = 'Foo' id = '' icon = 'misc_/Foo/icon' def __init__(self, id, title, status, REQUEST): """Create a new article entry""" self.id = id self.title = title Master(status, REQUEST) def manage_edit(self, title, status, REQUEST=None): """Change information for object""" self.title = title Master.manage_edit(status, REQUEST) The above simply fails to find the Master methods. I tried Master.Master.manage_edit, as well as doing self.master = Master(status, REQUEST) in __init__ and then master.manage_edit(...), but neither worked. Also, is it possible to access attributes of the Master class, or do I need to define methods in Master to return attributes?
