i have a table called requests which save the data of a form.  
but whenever i refresh the browser it again resubmit.it includes  
the following fields

user\_id, arrival, departure, date

this table can include same user\_id, arrival, departure.so that  
i couldn’t use the validates\_uniqueness\_of property. each column  
should be independent of others.can anyone  
suggest me a code which will avoid the resubmittion

find the error.
