问题 Simple question : I have a service class (let's say helpersService ) and a method def constructURI(params) . How can I call this method from a template view. I have tried the following code without success <% def helpersService = new HelpersService() // or def helpersService %> <img src="${helpersService. constructURI(params)}"/> But I get the following result: No signature of method: com.HelpersService. constructURI() is applicable for argument types... or (in case I use def helpersService )

问题 Is there a way to break out of a <g:each>? I have a page wherein I'm iterating through a list and I have to make sure that a checkbox is checked if that was the value stored in DB. To make it a little clearer, please consider something like: <g:each in=${list1}> <g:each in=${list2}> <g:if test="${list1.id == list2.id}"> <input type="checkbox" ... checked="checked" /> </if> </g:each> ... </g:each> where list1 is, say Domain1.list() (i.e. ALL possible values) and list2 is Domain2.find(...) (i.e

问题 In my Grails controller I'm responding to an AJAX call and using render to return the text: def ajaxRandomPersonName = { def person = get a random person ... render "Name: ${person.name}" } The problem is that render renders the whole template. So instead of just rendering "Name: John" it renders all the icons, navigation, etc defined in the template. How do I get render to just render without the template? I'm pretty much following Chapter 1 of "Grails in Action" (page 28) using Grails 1.1.1

问题 I am developing a grails application which uses lot of ajax.If the request is ajax call then it should give response(this part is working), however if I type in the URL in the browser it should take me to the home/index page instead of the requested page.Below is the sample gsp code for ajax call. <g:remoteFunction action="list" controller="todo" update="todo-ajax"> <div id ="todo-ajax"> //ajax call rendered in this area </div> if we type http://localhost:8080/Dash/todo/list in the browser

问题 I have a couple of Javascript libraries of my own that do some nice prettyfying of my HTML pages and I want to include them in my gsp pages, particularly the landing page of my app. I have tried putting them in views folder and web-app/js and $APP_HOME/scripts but when I load my index.gsp the scripts don't show up. I have also tried a variety of alternatives in my code none of which work... <script src="mylib.js" type="text/javascript"></script> <script src="js/mylib.js" type="text/javascript

问题 How can I invoke a service directly from a view? I'm trying with ${my.domain.service.method} , but it complains it can't find the property. And no, I don't want to use a controller because the view is a template. 回答1: <%@ page import="com.myproject.MyService" %> <% def myService = grailsApplication.classLoader.loadClass('com.myproject.MyService').newInstance() %> And then you can call ${myService.method()} in your gsp view Be aware that calling transactional service methods from views hurts

问题 I have lots of checkbox element on my Grails form , one is this: <g:checkBox id="consolidate" name="consolidate" value="${true}" checked="${false}" /> Then on the receiving controller , I verify the value of the checkbox using this code : println params?.consolidate And it displays: on Regardless whether I've tick my checkbox or not. In other language, if the checkbox is not ticked, its value on the controller will be null or undefined . What should be its value when unchecked, and what is

问题 I'm trying to use patterns for my gsp file in Grails. I want to check if the time entered is in the correct format. For example: 12.15 == 12:15 == 12,15 == 12-15 and so on. <g:field type="text" name="startTime" class="date" pattern="\\$##:##"/> <g:field type="text" name="endTime" class="date" pattern="[0-9]{2}:[0-9]{2}" /> That's my code. The patterns are just some trys. Maybe someone knows a solution. Greetings Nik 回答1: the pattern in your g:field tag will be pass into date template (for

问题 I have been intermittently encountering a difficult to replicate issue now for a few weeks. It seems (ie I can't yet be sure) that if the Grails app is not touched overnight something is perhaps unloaded causing: GSP rendered with values such as: <meta http-equiv="org.apache.commons.lang.StringUtils@72cd722b" content="org.apache.commons.lang.StringUtils@4e520b18"> <link href="/appname/static/bundle-bundle_application_head.css" type="org.apache.commons.lang.StringUtils@31da0262" rel="org
