Either that, or I'm probably not doing something right or don't know enough... + +Here's what I have running: +A user tries to signup with a post request. To be successful, the username has to be unique. The resource_exists/2 method responds with proper true and false values by looking at the request body. + +Here's what I want done: +Iff the resource_exists callback returns true, I don't want the AcceptResource callback to run at all. Instead, I want to send a 4XX status and halt. Is there a canonical way of doing this? + +Cheers, + +AH +</PRE> + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + + <LI>Next message: <A HREF="000469.html">[99s-extend] Prevent resource creation on POST +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#468">[ date ]</a> + <a href="thread.html#468">[ thread ]</a> + <a href="subject.html#468">[ subject ]</a> + <a href="author.html#468">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://lists.ninenines.eu/listinfo/extend">More information about the Extend +mailing list</a><br> +</body></html> |
