Question

I’m a newbie…

I know how to use “to_sentence” when I have something like:

<%= @blah.collect {|b| b.name}.to_sentence %>

but what if I have a more complex block like:

<% skill.position.each do |position| %>              
  <a href="<%= position.company.url %>"><%= position.company.name %></a>
  <% if position.salary? %>
    <span><%= position.salary %></span>
  <% end %>
<% end %>

The desired output is:

Microsoft, Google 2000, and Yahoo.

Answer 1

Couldn’t you just collect it without .each?

<%= skill.positions.collect{ |p| "<a href=\"#{p.company.url}\">#{p.company.name}</a>#{position.salary? ? '<span>#{position.salary}</span>' : nil}" }.to_sentence %>

That should work for you…

You could also do this:

<%= skill.position.each do |position| %>              
  <a href="<% position.company.url %>"><% position.company.name %></a>
  <% if position.salary? %>
    <span><% position.salary %></span>
  <% end %>
<% end.to_sentence %>
