Does respond_to play nicely with render :update?

Rails
1

I have a custom format that I’m using called ‘desktop’.

I have an action which is called via AJAX, and I’d like to update a div
in my page with a partial.

The request comes in with params[:format] == ‘desktop’, and my partial
is named _search_results.desktop.erb

However, when I do this in my action:

respond_to do |format|
format.desktop {render :update do |page|
page.replace_html(‘search_results’, :partial =>
‘search_results’)
end}
end

I keep getting errors about missing _search_results.html.erb.

Can you not use a custom format with the render :update do |page| idiom?

Thanks,
Wes

I think I remember an issue that when using custom formats you need to
give the full path the the partial like :partial => ‘posts/
search_results’.

That doesn’t seem to work for me.

Try to include the extension – :partial => ‘posts/
search_results.desktop.erb’.

If I do this, it works:

page.replace_html(‘search_results’, render(:partial =>
‘search_results’))

Notice that originally, I was passing just the hash key/value pair, but
now I am passing a render call.

According to the API docs:

“options_for_render may be either a string of HTML to insert, or a hash
of options to be passed to ActionView::Base#render.”

which is what I was doing that wasn’t working. I wonder if what happens
when I pass the render call, is that returns a string that is used in
the replace_html call.
