At some point when creating a Flex application you will want to update an item in the database using Rails(e.g. the details about a film).

To update a resource using REST you need to use the HTTP verb PUT, so the code below should work if we’re updating a film with ID=1:

<mx:HTTPService  id="UpdateFilm" 

Unfortunately the above code doesn’t work, if you look in the rails logs you’ll find it’s doing a POST. HTTPService supports GET|POST|PUT|DELETE, but only if the useProxy is set to true (which means your using a Flex Data Services).

The manual states if useProxy=”false” you can only use GET or POST. Not particularly good if you want to get some rest in:-)

Luckily Rails has a work around for this, which is the detection of a _method parameter on the end of a URL. For example:

<mx:HTTPService  id="UpdateFilm"

Some of the REST resources on this site are:
