grails-controller

问题 I need to read out all available actions from any controller in my web-app. The reason for this is an authorization system where I need to give users a list of allowed actions. E.g.: User xyz has the authorization for executing the actions show, list, search. User admin has the authorization for executing the actions edit, delete etc. I need to read out all actions from a controller. Does anyone has an idea? 回答1: This will create a List of Maps (the 'data' variable) with controller

Example use of ExpandoMetaClass: static { ExpandoMetaClass someService = new ExpandoMetaClass(Object, false) someService.accessAnotherSystem = { return 'success' } someService.initialize() SomeService.metaClass = someService } Note: currently the service isn't defined for the controller but since it's a spring bean referencing the class named

问题 With Grails 2.3.4, and scaffold 2.0.1; no object appears in the index (list) page of the controllers. The views are being automatically created by grails official scaffolding plugin.

问题 I am trying to get a custom JSON renderer for exceptions working in my REST api. I was able to get a custom marshaller working that did most of what I needed, but I would like to have control over the context that I don't have access to in the marshaller.

Grails docs: http://grails.org/doc/2.3.4/guide/webServices.html

问题 For Grails 2.3.3, it allows same name controller in different package with namespaced controller according to http://grails.org/doc/latest/guide/theWebLayer.html#namespacedControllers So we have package like this: /admin/FooController /public/FooController To keep consistent we want the view package like this: /views/admin/foo/... /views/public/foo/...
