I have a couple of block helpers, here's a simple example of what I'm doing:

def wrap_foo foo, &block
    data = capture(&block)

    content = "
      <div class=\"foo\" id=\"#{foo}\">
        #{data}
      </div>"
    concat( content )
end

I'm just trying out erubis and it's giving me the following error:

You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.<<

Removing the call to concat removes the error but ends up with my wrapper not being rendered

Using:

  • Rails 2.3.5
  • Erubis 2.6.5
  • And tried this gem that helps Erubis (though 2.6.4) and Rails 2.3 play better together

Actually using the rails_xss plugin, which was my ultimate goal contains a fix for this.

I just had to change my helper to do this concat( content.html_safe! )

Erubis and Rails 2.3 don't work together well. Check out this post: http://daveelkins.com/2009/06/18/making-erubis-264-and-rails-23-work-together/ He has created a gem on github that gets them to work together.
