I am currently writing an application to collect data from a survey  
form. I would like to write it so that it saves all of the information  
from various radio buttons into the database. Obviously, I could hard-  
code each individual radio button to be collected but I want to create  
a loop that automatically does this in case new questions are added.  
Here is some sample code I tried to use (but failed, obviously)

while( count )  
@question = Question.new  
@code = “:q\_code” + String(count)  
if( params[:survey][@code] )  
@question.question\_code = code  
@question.user\_id = @user.id  
@question.value = params[:survey][@temp]  
@count += 1  
@question.save!  
else  
count = false  
end  
end

As you can tell, I am trying to pass a variable name to params. Is  
there a way to do this? Thanks!
