Question

I’m trying to do the ‘rails for zombies’ course on codeschool, but I’m stuck on this one:

http://railsforzombies.org/levels/3/challenges/3

The frustrating thing about this course, is that you can’t refine your answers, because you don’t see the return value from incorrect solutions.

Anyway, the database looks like this:

id  name    graveyard
1   Ash     Glen Haven Memorial Cemetary
2   Bob     Chapel Hill Cemetary
3   Jim     My Fathers Basement

The challenge is to “Use an each block to print the names of all the Zombies”

My solution is:
<%
zombies.each do |z|
puts z.name
end
%>

This fails, but I don’t get to see how it fails, so I can’t refine it.
What is the solution?

Answer 1

Try this:

<% zombies.each do |z| %>
  #note the equal-to sign below. this means that the text will be sent as output
  <%= z.name %>
<% end %>

Notes:

• puts is used to output the text to the console
• <%= %> is the way to output text in an ERB template
