The code you posted doesn't make any sense, you are overriding the create method to call the write method to change the record with id = 1 with the vals of the create method. The error is that the record with id = 1 could be not created or deleted, you are not calling the super create so you cannot create anything using this method.

If you want to write / update some value after record create you should write like that:

def create(self, cr, uid, vals, context=None):

   id = super(class_name, self).create(cr, uid, vals, context = context)

   vals.update({'field_name': value})    //   here you can give fields name for which you want to update value.

   self.write(cr, uid, id, vals, context=context)

  return True
