如何将一个变量从布局文件传递给Grails模板? [英] How do I pass a variable into grails template from a Layout file?
问题描述
(我们已经尝试过使用Grails导航插件,因为我们有不同的选项卡,指向相同的控制器(相同的视图,不同的过滤器)。)
我一直都在使用这种模式。在我看来,我可以手动或通过使用我正在渲染的视图中的参数标记将属性附加到页面。它没有在Grails用户指南中记录,但它的超级方便。
< parameter name =foovalue =bar />
然后,我将通过使用 pageProperty标签。
< g:set var =activeNavItemvalue =$ {pageProperty(name:'page.foo')} />
布局根本不需要处理这个变量: - )
So I have a navigation template (/common/_navigation.gsp) that is getting rendered in the Grails projects main Layout file (/layouts/main.gsp). How do I pass some kind of variable/parameter/arg from the individual view files to layout and eventually into the navigation template? I just want the right tab to be highlighted when I'm on a page.
(We've already tried using the Grails Navigation Plugin. Since we have different tabs that point to the same controllers (same view, different filter) it breaks down.)
I do this pattern all the time. In my view, I can attach a property to the page either manually or by using the parameter tag in the view that I'm rendering. Its not documented in the Grails user guide, but its super handy.
<parameter name="foo" value="bar" />
Then I would access the page property by using the pageProperty tag.
<g:set var="activeNavItem" value="${pageProperty(name: 'page.foo')}"/>
The layout doesn't need to handle this variable at all :-)
