Favorite Create do a POST with this url /1/favorites/17983195453/create.xml and you get " /1/favorites/17983195453/create.xml Not found " I checked, the ID is correct. Moreover this can be easily repro in Twurl to the same result
Destroy performing a POST with id as parameter returns " /1/favorites/destroy.xml This method requires a GET. " Which is garbage since GET is obviously neither the right mode nor in the documentation. Even if one was to use GET and pretend is the right mode, it still does now work (it does not remove the relationship) and it returns a null array. Please fix :-) Thanks!
