Im trying to get the multiple selected data from select_tag., but its gives single data

I hv written. <%=select_tag( :cons_attribute_id,options_from_collection_for_select (Attribute.find_all_by_attributetype("cons"),                 "id", "name", 3),:multiple=>true) %>

I hv also written as:

<%=select_tag( :cons_attribute_id,options_from_collection_for_select (Attribute.find_all_by_attributetype("cons"),                 "id", "name", 3),:multiple=>true) %>

  but it gives error.. such as method not defined

when you write :foo ruby thinks that you want to call the method on the symbol :foo. You can be explicit that you want the symbol with content foo by doing :'foo' In this case you could also just pass a string to select_tag
