.erb files

You can block HTML within ruby code.

<% 3.times do -%>
Ho!<br />
<% end %>
Merry Christmas!

Loop which in turn sets a variable:

<% 3.downto(1) do |count| -%>
<%= count %>…<br />
<% end %>
Lift off!

Escape HTML using h()

Email: <%= h(“Ann & Bill <frazers@isp.email>”) %>

Symbols and linking to Actions in Rails

Think of symbols in rails as “the thing named”.

So in a link for example <%= link_to “goodbye”, :action => “goodbye” %>

The thing named :action => “goodbye”

Looping through objects

<% for file in @files %>
file name is: <%= file %>
<% end %>

OR

<% @files.each do |file| %>
file name is: <%= file %>
<% end %>
