how could i trigger a function after i click save in OpenERP 7?
In my custom module, i wish to auto increase the "version_number" parameter where every time the user click save it will trigger a function to execute the logic of "ver=ver+1" and write back to the "version_number" fields. How could i do that?
I tried use "def write()" but not sure exactly how it could be done. Appreciate your kind help. Thanks!
You need to override write method.
def write(self, cr, uid, ids, vals, context=None):
res = super(your_model, self).write(cr, uid, ids, vals, context)
self._increment_version(cr, uid, ids)
return res
def _increment_version(self, cr, uid, ids):
for record in self.browse(cr, uid, ids):
cr.execute('update table_name set version_number=%s where id=%s' % (record.version_number + 1, record.id))
