Put everything inside the div into a partial. Put the link\_to\_remote  
around the  
partial, like this:

\<%= link\_to\_remote render(:partial =\> ‘my\_partial’), :url =\> {…} %\>

I suspect you’ll get an with an entire stretch of HTML inside, not  
just a  
string. Report back if the link\_to\_remote calls h() on the HTML!

Oh yeah and test the living crap out of it, preferably with  
assert\_xpath,  
because it’s going to be a major hazard at code upgrade time!

When you test that, it will produce an , so capture that. First put a

\<div id='clickable\_div' around the linker. Then capture it like this:

assert\_tag\_id :div, :clickable\_div do  
assert\_xpath ‘a’ do |a|  
assert{ a[:href] == ‘#’ }  
puts indent\_xml  
end  
end

When you run that test, the puts indent\_xml will spew out the contents  
of the  
partial inside the .

Then you can call assert\_tag\_id or assert\_xpath, again, to find some  
detail  
inside the partial.

This way, a change that looks harmless, to the or the partial, has  
greater  
odds of raising a red flag instantly, while testing.
