How to render html + string in link_to anchor?

In a Rails app I have helper methods that render html snippets, e.g. Twitter bootstrap fonts

def edit_icon
  content_tag(:i, "", :class=>'icon-edit')
end

I want to display this in a link anchor with additional text appended. e.g.

<%= link_to "#{edit_icon} Edit this Record", edit_record_path(@record) %>

This is currently rendering the content_tag as a string, not as HTML. How do I render it as HTML?

I experimented with <%= link_to "#{raw edit_icon} and <%= link_to "#{edit_icon.html_safe}, but these don't seem to be what I need in this case.

Thanks for any ideas.

The issue is Rails string interpolation transforms the HTML output of content_tag into a "safe" format. The fixes you tried both operate before string interpolation is applied, which won't work

Fixing the problem requires just a small change: move the method call outside of the string.

Do this:
    <%= link_to edit_icon + "Edit this Record", edit_record_path(@record) %>
Instead of:
     <%= link_to "#{edit_icon} Edit this Record", edit_record_path(@record) %>
