Need to pass lead custom field value to partner when converting to lead to partner in OpenERP 7 -

I am new to OpenERP 7 and when I convert one, trying to give a custom field value with lead from lead Lead to partner.

I understand that I need to modify or add some functions to the magician directory of my new module (I think I need to increase the CRM module)

correct? Can anyone recommend me any examples or can I suggest some suggestions?

Thanks in advance.

There are two ways defined in the CRM. _lead_create_partner and _lead_create_contact . These methods make partners and contact respectively. You can override these methods (formerly using the _lead_create_partner ) value for the participant.
