grails

问题 Thanks for any help you can offer. I have a Grails project that I'm trying to install Karma into.

问题 I have been searching on Google for a really good while, and I cannot find a solution to this problem. I am trying to access a JavaScript variable from my GSP file in my Groovy controller, but I can't find out how to do this. Example: //JavaScript stuff <script> function validateForm(){ var ret = false } </script> //Groovy controller stuff def myAction = { println params.ret } How do I achieve something similar to this? 回答1: Two ways to pass a variable to the controller: Ajax Form submit Ajax

问题 I'm trying to create a generic function in grails that will allow me to specify a class and function name, and intercept any function calls based on that criteria: getSomeClass().metaClass.invokeMethod = { String methodName, args -> MetaMethod someAction = getSomeClass().metaClass.getMetaMethod(methodName, args) def result = someAction.invoke(delegate, args) if (methodName==getSomeMethodName()) intercept(args, result) return result } This works for POGO, and domain classes, but does not seem

问题 I often write something like: def myAction{ MyActionCommand cmd -> if( cmd.hasErrors() ){ return render(status:HttpServletResponse.SC_BAD_REQUEST ); }else{ // actual action logic } So, I'd like to extract that common pattern into some reusable location. Filter looks like good candidate, but I can't find the way to get command object from the filter. Tryed something like this (in filters closure): formValidation( controller:'*', action:'*' ){ before = { cmd -> if( cmd.hasErrors() ){ response

问题 I am just learning grails and have a problem with an app that works fine when I run it in Netbeans but shows strange behavior when deployed to Tomcat 7.0.22 on a Centos 5.4 server. I am using the proxy_ajp to make the app available with apache. The problem seems to be with the session not being maintained after a redirect so that I lose the login information causing the app to try to login again. My proxy_ajp settings are <Location /PreyerBooks > ProxyPass ajp://localhost:8011/PreyerBooks
