Handling parameters from dynamic form for one-to-many relationships in grails

阅读更多关于 Handling parameters from dynamic form for one-to-many relationships in grails

问题 My main question here is dealing with the pramas map when having a one-to-many relationship managed within one dynamic form, as well as best practices for dealing with one-to-many when editing/updating a domain object through the dynamic form. The inputs for my questions are as follows. I have managed to hack away a form that allows me to create the domain objects shown below in one Dynamic form, since there is no point in having a separate form for creating phone numbers and then assigning

Grails Redirect Post-Logout Using spring-security-core-3.0.6+

阅读更多关于 Grails Redirect Post-Logout Using spring-security-core-3.0.6+

In spring security version 3.0.6, which fixed a CRLF logout exploit ( https://jira.springsource.org/browse/SEC-1790 ) they disabled the use of the 'spring-security-redirect' parameter. Default support for the redirect parameter in logout URLs has also been removed in 3.0.6. In 3.1 it already needs to be enabled explicitly. Is there a way to turn the redirect parameter back on, so that I can dynamically redirect in my Grails Spring Security Logout Controller? LogoutContoller.groovy def user = springSecurityService.currentUser if (params.redirect) { // this needs to log the user out and then

Reading out all actions in a Grails-Controller

阅读更多关于 Reading out all actions in a Grails-Controller

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? This will create a List of Maps (the 'data' variable) with controller information. Each element in the List is a Map with keys 'controller', corresponding to the URL name of the controller

Inject grails application configuration into service

阅读更多关于 Inject grails application configuration into service

I'm creating a grails service that will interact with a 3rd party REST API via a Java library. The Java library requires credentials for the REST API by means of a url, username and password. I'd like to store these credentials in configuration/Config.groovy , make them available to a service and ensure that credentials are available to the service before it requires them. I appreciate that grailsApplication.config is available to controllers and that through a method of a service the relevant config values can be provided to the service, such as this: package example class ExampleController {
