Error when calling superclass __init__ method

Maese Fernando

Hi,

I'm getting an odd error while trying to call the __init__ method of a
super class:

BaseField.__init__(self)
TypeError: unbound method __init__() must be called with BaseField
instance as first argument (got nothing instead)
This is the code:

class BaseField(object):

def _addFieldsToRec(self, rec, *fields):
for field in fields:
self.mfn[field] = rec

def __init__(self):
self._addFieldsToRec(1,1)
self._addFieldsToRec(2, 500,501,502,503,504,505,506,507,508)
class Field(BaseField):
def __init__(self, value):
BaseField.__init__(self) # this seems to be the offending
line.
self.tag = value
What am I doing wrong?

No, it isn't. Please provide the actual code or, better, a minimal
example. Don't forget to run it to verify it shows the behaviour described
above before you post it.

My bets are on

BaseField.__init__() # no self
