Question

In reference to this

I’ve created a question in a webform like this:

<div class='form_row'>         <label for='features[]'>Features:</label>         <% [ 'scenarios', 'role_profiles', 'private_messages', 'polls' ].each do |feature| %>           <br><%= check_box_tag 'features[]', feature,                   (params[:features] || {}).include?(feature) %>         <% end %> </div> 

So if scenarios and private_messages gets checked and I print out params[:features] I will get: scenariosprivate_messages

I was wondering how would I be able to obtain scenarios and private_messages separately from params. Is the mapping params[:features] = 'scenariosprivate_messages' or is it really params[features] = ['scenarios', 'private_messages'] ? If it’s the latter how can I loop through them?

I write in my view:

<%= params[:features].each {|param|     param.capitalize } %> 

and I still just get scenariosprivate_messages printed.

Try this instead:

<% params[:features].each do |param| %>   <%= param.capitalize %> <% end %> 

The problem with your original solution is that you’re printing out the result of the block, which is the array itself, rather than printing out each element of the array.
