Rails - Append content to helper method's block without <%= %>

Question

I'm trying to create a helper method that appends stuff and shows the block inside of it, like this:

def test &block 
   %{<div> 
      <div> Example content </div>
       <p> #{capture(&block)} </div>
     </div>}.html_safe()
end

when I call it like this

<%= test do %>
 **stuff
<% end %>

it works properly, but when I also need to call it from the controller using ERB.new(), and when I do so, I get an error:

the call:

@result = ERB.new(
%{<%= view_context.test do  %>
    <div>content to show inside</div>
  <% end %>}
).result(binding)

the error:

SyntaxError ((erb):2: syntax error, unexpected ')'
ncat(( view_context.test do  ).to_s); _erbout.concat "\n

so I need to call without the " = ", <% test do ... %>, but when I call it like this, the appended content isn't shown

what am I missing?

Answer 1

Maybe using content_tag in your helper would be a better way to do this.

For your error, it may be because you are doing the whole ERB.new(...) in your view, should be in an helper.
