Hello all,

I try to override 2 or 3 methods of the file ../openerp/addons/base/ir/ir_attachment.py.

My goal is to change the name of the stored attachments files on the hard disk.

I already have other custom modules working. 

I have tried many combinaison, I have searched, but it doesn't work now.

__init__.py and __openerp__.py seems to be right since my own ir_attachment.py file is loaded.

My module depends on 'base' :

For the moment, I have this code in ../addons/mymodule/ir/ir_attachment.py : 

from openerp import models, fields

class PTir_attachment(base.ir_attachment):
    _inherit = 'base.ir_attachment'
    _name = 'base.ir_attachment'
    def _get_path(self, cr, uid):
        import pdb; pdb.set_trace()

I always get this error :

    import ir_attachment

  File "/home/odoo/addons/report_lapagept/ir/ir_attachment.py", line 4, in <module>

    class PTir_attachment(openerp.base.ir_attachment):

NameError: name 'openerp' is not defined

Could you help me please? I miss something...
