    copied!<p>I have a Rails 3 application, say, with hotels, where hotels belong to parent areas. When a user hits the app (served by mongrel >> nginx), I want the domain name used in the request to decide what area of hotels to serve up (domain name >> area). To achieve this I can see two options: </p> <hr> <p><strong>1)</strong> Rewrite the URL with nginx, inserting the area id after the domain name (e.g. birminghamhotels.co.uk => proxy_pass <a href="http://myupstream/areas/3" rel="nofollow noreferrer">http://myupstream/areas/3</a>$request_uri). </p> <p><em>Benefits:</em> Domain to object mapping happens where accepted domains are defined: nginx.conf. Should be transparent to users (pretty URLs possible as they are rewritten).</p> <p><em>Drawbacks:</em> Breaks Rails url helpers, no more link_to or form_for. Hard-coded object reference is naughty.</p> <hr> <p><strong>2)</strong> Catch the domain name in routes.rb and look up the Area via a unique "domain" attribute for each Area (or even a has_many if you fancy). </p> <p><em>Benefits:</em> Should allow use of all Rails URL helpers. Requested domain linked directly to resource so exceptions can be handled. </p> <p><em>Drawbacks:</em> Without rewriting URLs with nginx, wouldn't users see: birminghamhotels.co.uk/areas/3/hotels/42 instead of just birminghamhotels.co.uk/hotels/42? Also, I don't have a clue how to do it! </p> <hr> <p>So, I've tried option #1 but ran into trouble with URL helpers etc. I've tried to come up with a way of trying option #2 but haven't been able to suss the correct syntax despite a lot of ogling. Now the fact I cannot find any answers by searching makes me think I got the wrong end of this problem. Is there a third option? How would you solve it? </p> <p>Oh and btw, I am not building another hotel listing website - plenty enough of those around already. Just happened to be a close enough example. </p>
