I am trying to detect Blackberry user agents in my app, which works fine in my development version. But nothing happens when I redeploy the app in production.
application_helper.rb
def blackberry_user_agent?
request.env["HTTP_USER_AGENT"] && request.env["HTTP_USER_AGENT"][/(Blackberry)/]
end
application.html.erb
<% if blackberry_user_agent? -%>
<div class="message">
<p>Using a Blackberry? <a href="http://mobile.site.ca/">Use the mobile optimized version</a>.</p>
</div>
I've tried clearing the cache using rake tmp:cache:clear and restarted mongrel a few times. Apparently the HTTP_USER_AGENT is coming back nil in production. I am using Nginx with a mongrel cluster.
