How can i link two one2many lists?

Question

I wish to link(relate) two many2one lists, for example my custom module ng.machine  and account.invoice

the account one:

'machine_ids' : fields.one2many('ng.machine', 'invoice_ids', 'GÃ©pek'),

the machine one:

'invoice_ids' : fields.one2many('account.invoice', 'machine_ids', 'SzÃ¡mlÃ¡k'),

but this gives me an error.If i change the fields to many2one then until i try to save everything works. when i try to save gives me this error:

ProgrammingError: can't adapt type 'dict'

How can i make i

'invoice_ids':
fields.many2many(
'account.invoice',
'ng_machine_rel', # same relation still
'machine_id', # ...but f
