ArgumentError (Unsupported argument type: 0 (Integer)):

Question

My search form looks for an object in the database based on the address field. Everything works fine if i search only for the city name, for example Milan, but the search breaks if a select the complete google maps address suggested via maps Api. For example "metropolitan city of Milan" or some address "Via Paolo Sarpi, Milano, Metropolitan City of Milan, Italy" I got:

ArgumentError in PagesController#search
Unsupported argument type: 0 (Integer)
