Question

I have an array in my view file. Each value in the array contains html. I want to go through the array and not escape the html. However, whenever I run html_safe or raw, the array is displayed with non-escaped html. Below are some of the methods I tried that proved a failure.

This returns the array with escaped html…

<%= @posts.each { |x| puts raw(x) } %>

This returns with each value in the array as nil…

<%= @posts.map { |x| puts raw(x) } %>

Finally, inspect returns the array with escaped html…

<%= @posts.inspect { |x| puts x.html_safe } %>

This returns with nil as well…

<%= @posts.map { |x| puts x.html_safe } %>

What’s causing this and how do I fix it?

Answer 1

Your problem is with the <%= at the start of every example – this will output the result of the expression, which is @posts itself.

Replace it with <% and see how you go.

edit: The first example is the one I would use, with each and raw.

edit again: puts really isn’t typical in views – try something like the following:

<% @posts.each do |post| %>
  <%= post %>
<% end %>
