How to send list value in Ruby Sinatra?

I have a simple form where there is a list: 

     <form method ="post" action ="">
     <select>Select subject
        <option value="1">Maths</option>  
        <option value="2">Science</option>
     </select>
      <input type="submit" name="Submit" />

My question is, if I select the option Maths, I would like the value to be sent eg /1. What should be written in action? How should the route be written ?

       get '' do 


       end

we tend to look at queries as GETs (makes sense, it is after all retrieving information) rather than a POST which (doesn't actually change data) yet responds with a result page

a common (gnarly) pattern we often see is to rewrite (in js or redirect) to the form

GET '/search/:q1/and/:q2' do // result of search filtered by q1 and q2 end

which is also quite neat

Your route could look something like this:

post '/subject' do
  @subject = params[:subject]
  # do whatever you want now
end

But you would need to give your select tag a name and your form an action:

<form method="post" action="/subject">
    <select name="subject">
    <!-- etc etc -->

Also have a look at related questions.
