I am trying to use the tabs function from jQuery UI in a Rails app. I
am using a helper for the navigation and I would like to keep it that
way. The code in my helper is:
def links_for_navigation
html = ""
html = <<HTML
<ul>
<li><a href="#tabs-1">Courses</a></li>
<li><a href="#tabs-2">Parts</a></li>
<li><a href="#tabs-3">Categories</a></li>
</ul>
<div id="tabs-1"><% link_to "Courses", courses_path %>
<div id="tabs-2"><% link_to "Parts", parts_path %>
<div id="tabs-3"><% link_to "Categories", categories_path %>
HTML
end
My view pulls in the code with <% links_for_navigation %>
It's telling you that is can't fine your HTML template before it
reaches the end of the file it is processing. It may be that the frame
work is looking for your HTML template at the end of the file that is
making the call and not the helper.
Personally I don't like using the inline template in a method because
it doesn't allow you to easily change the template without touching
that method. I would save the template off to it's own file in the
view folder (somthing like tabs.html.erb) and then in the helper
method read and process the template returning the result to whaterver
called it.
def links_for_navigation
template = ERB.new File.read("tabs.html.erb")
html= template.result(binding)
end
The terminating string for a here-doc can't be indented - so that's
your first problem.
I'm hoping that the missing </div> tags are just a typo in the above,
as are the missing =s on the ERB tags (not going to get much
output...). As written, you're actually going to get the ERB tags un-
interpreted in the output HTML.
Take a look at the Layouts and Rendering guide:
specifically the parts about partials for a cleaner way to do this.

end
When I try to load the page I get "cannot find string HTML before EOF
What am I doing wrong?

unless you reference the here-doc like:
html = <<-HTML
<ul>
...
HTML
That extra '-' in the <<-HTML allows the ending token to be indented.
