Odoo is the world's easiest all-in-one management software. It includes hundreds of business apps:
CRM | e-Commerce | Accounting | Inventory | PoS | Project management | MRP | etc.
You need to start by reading the implementations in the osv.fields module. In nutshell, all fields are inherited from _column. Depending on the nature of the field you are creating, you might need to implement your own "set", "get" and "serach" methods to handle the database interaciton. Here is small example to get you started. You can read more from the sourcecode of fields.py
from openerp.osv import fields, osv
_type = 'char'
def __init__(self, string="unknown", size=None, **args):
fields._column.__init__(self, string=string, size=size or None, **args)
# self._symbol_set_char defined to keep the backward compatibility
self._symbol_f = self._symbol_set_char = lambda x: _symbol_set_char(self, x)
self._symbol_set = (self._symbol_c, self._symbol_f)
fields.mynewfield = mynewfield
