Question

I am doing some research on Grails and writing about what the future holds for it..

Something interesting jumped out in the RoadMap (http://grails.org/Roadmap)

GORM for REST

Anyone with more experience with Grails than me know what this would entail?

I am guessing some sort of CRUD operations through Web Services instead of using Hibernate to connect to an SQL database?

Answer 1

there is a JSON RESTful API for GORM which gives some insight on what GORM for REST is like:

• GET on /context/api/domain-class-name returns a list of domain objects (possible arguments are the same as for the DomainClass.list() method argument map)
• POST on /context/api/domain-class-name creates a new instance
• GET on /context/api/domain-class-name/id retrieves the given instance
• PUT on /context/api/domain-class-name/id updates the given instance by ID
• DELETE on /context/api/domain-class-name/id deletes the given instance

As far as to RESTy GORM that is scheduled for Grails 2.0, here is the GORM Virtual REST domain objects discussion on Grails mailing list:

I am currently evaluating the use of grails to connect to other backend systems. Would it be possible to let the domain layer talk to CRUD REST services instead of a Database? It would be a bit like a XML backend…. We have got a very big backend where it is difficult to implement business logic, but we can manage to provide restful services. My idea is to have grails as a business / web application layer on top to deploy various systems to cross platform

This feature is scheduled for development for Grails 2.0
