Hi Guys,

I am very new to Ruby and Rails, am trying to understand the syntax of it. I got this code from a book but can't understand what does "</

"end.to_s" do. Here is the complete "view" code. Note: This

code works fine

<h2>A Simple Form</h2> <%= start_form_tag(:action => "show_formdata") %> <p>Text Field: <%= text_field_tag("name", "Aneesha") %></p> <p>Drop-down Selection Box: <% languages = ["Ruby", "Java", "C#"].map do |lang| "<option>#{lang}</option>"end.to_s %>

<%= select_tag("prog_languages", languages, :multiple => "true") %></p> <p>Checkboxes: <%= check_box_tag("operating_systems", "Windows") %>Windows <%= check_box_tag("operating_systems", "Linux") %>Linux <%= check_box_tag("operating_systems", "Mac") %>Mac

</p> <%= submit_tag("Submit Form") %> <%= end_form_tag %>

This is mostly just confusingly formatted. Another way to write it would be

<% languages = ["Ruby", "Java", "C#"].map { |lang| "<option>#{lang}</

" }.to_s %>

You're also following some very old examples - at least 2 years old.
