Re: RESTful (Form) Validation?

AD,

I would just want to say that your reply was helpful! I'm now reading the details of crud/Error/CrudExceptionRenderer.php  and crud/Error/Exception/CrudValidationException and I'll be taking cue from these. It also looks like the friendsofcake/crud plugin will be very useful to me someday when I start on a new project. For now, I'll just be taking bits and pieces from that idea since I'm already in the middle of prototyping.

Cheers,
OJ

Hi folks,

I was wondering if there was a way to let the client app know which fields it submitted have validation errors. (As you can see, I placed "Form" between parentheses because there isn't really an HTML form in a REST API request.) While the Cookbook recommends to use the built-in Exception classes to respond to errors in REST requests, there is no recommended way to include Model::validationErrors in the response.

Right now, I'm inclined to create my own subclass of HttpException, but after reading the core files, it looks like I might also need to create a custom ErrorHandler and ExceptionRenderer class, if I understand correctly. Essentially, I just want to add a 'validation_errors' key in the '_serialize' array exported by ExceptionRenderer.

The question is, will I be overdoing it if I did what I outlined above, *or* should I just pass a implode()'d Model::validationErrors as a $message to BadRequestException/InternalErrorException? Also note that Model::validationErrors is a multi-level array with named keys.

Cheers,
OJ
