    <p>I am using Backbone and jQuery on the front and have an API using Python/Tornado. Because my API is at <a href="http://api.domain.com" rel="nofollow">http://api.domain.com</a> and the site is at <a href="http://domain.com" rel="nofollow">http://domain.com</a> when I try to save a Backbone model it does an OPTIONS request first. The problem is it says "Load canceled" even though the server returned a valid response.</p> <p>Request Headers:</p> <pre><code>OPTIONS /user/xdfr456890sd HTTP/1.1 Host: api.domain.com Connection: keep-alive Access-Control-Request-Method: PUT Origin: http://domain.com User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_1) AppleWebKit/537.4 (KHTML, like Gecko) Chrome/22.0.1229.94 Safari/537.4 Access-Control-Request-Headers: origin, content-type, accept Accept: */* Referer: http://domain.com/settings Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 </code></pre> <p>Response Headers:</p> <pre><code>HTTP/1.1 200 OK Date: Thu, 06 Dec 2012 05:41:51 GMT Content-Type: text/plain Content-Length: 0 Connection: keep-alive Server: TornadoServer/2.4 Access-Control-Allow-Credentials: true Access-Control-Allow-Origin: http://domain.com Access-Control-Allow-Methods: PUT, DELETE, POST, GET Access-Control-Allow-Headers: Origin, Accept-Language, Accept-Encoding, Accept-Charset, Access-Control-Request-Headers, X-Scheme, Connection, Accept, User-Agent, Access-Control-Request-Method, Host, Referer, X-Real-Ip </code></pre> <p>Am I missing something? Doing something wrong? I have experimented with every possible combination of response headers and their values. <code>Access-Control-Allow-Origin</code> is whatever the <code>Origin</code> request header is.</p>

    1. COLooks like these headers need to be returned on all requests and not just the OPTIONS request.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
