grails-2.0

问题 I have some (non-Grails-artifact) classes that access the service layer beans via passing around the grailsApplication object. However I'm having trouble unit testing the classes implemented in this way. Why doesn't the bean get registered in the main context? @TestMixin(GrailsUnitTestMixin) class ExampleTests { void setUp() {} void tearDown() {} void testSomething() { defineBeans { myService(MyService) } assert grailsApplication.mainContext.getBean("myService") != null } } The above code

问题 I am new to Grails and I like it very much. I want to place my classes in packages like org.company.project.module.model . Its quite painful for to me to repeat create-domain-class <package>.<class_name> . Is there something like "package templates" or can I somehow "enter" (like grails cd org.comopany... ) and then just write Class names ( grails Person will be generated in ./ location)?

问题 The Grails 2.0.4 documentation for validation shows you how to display error messages at the top of the page and how to add a css class to an element if a field is invalid, but it doesn't tell you how to display the error message next to the fields themselves, something like this: ----------------------- Name: | | You must enter a name! ----------------------- How do you retrieve the specific error message for an invalid field and then display it next to the field it's for? 回答1: Actually, the
