    <p>It sounds like you may have two problems:</p> <p><strong>How do I actually send the CSRF token with my POST requests from Flash?</strong></p> <p>Django also accepts CSRF tokens via the header <code>X-CRSFToken</code>. <a href="https://docs.djangoproject.com/en/dev/ref/contrib/csrf/" rel="nofollow">See the docs here</a>.</p> <p>You can append headers to your request like so: </p> <pre><code>var req:URLRequest=new URLRequest(); req.url="http://somesite.com"; var header:URLRequestHeader=new URLRequestHeader("X-CSRFToken","foobar"); req.requestHeaders.push(header); </code></pre> <p><a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLRequest.html#requestHeaders" rel="nofollow">URLRequests docs are here</a>.</p> <hr> <p><strong>How do I get the CSRF token into my Flash file in the first place?!</strong></p> <p>(Option A) Because CSRF tokens are generated on a <em>per request</em> basis (e.g., with templating a traditional HTML form, on a GET request) the simplest thing to do is to pass the CSRF token to the Flash file via a templated parameter. Something like: <code>&lt;param name="csrf_token" value="{{ my_csrf_token }}" /&gt;</code></p> <p>(Option B) It sounds like you don't want to do the parameter thing, so your final option is to build a custom Django view which has the sole functionality of delivering a CSRFToken to your Flash file. So the Flow would be your Flash file loads, your Flash makes a GET request to <code>http://mysite.com/csrf_token/</code> which simply returns a valid CSRF token, and then you can use that token to do your POST. (Note you will need to do a GET request for each POST request).</p>

    1. COHi Chris, thanks for the detailed explanation. Option B sounds like a possible plan, but I'm unsure about the security implications of opening an endpoint just to get csrf token, because referral headers are spoofable. What is your perspective about this potential possible exploit, and whether it is a valid concern?

    2. CO@vken, I'm no security expert so I don't think I understand the full implications of an AJAX generated CSRF. Check out [this question for some related info](http://stackoverflow.com/questions/3664044/anti-csrf-token-and-javascript). However I believe you are protected using the methodology in option B.

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.
