grails - render Grails tag in controller

Question

I've to render a select when calling a controller function.

class FormController {
    def document() {
        render """<g:select name="tipo" from="${['','one','two']}" />"""
    }
}

it doesn't work.. In the html appear nothing when I replace a div with this function.

Answer 1

代わりに、タグをメソッド呼び出し構文として使用します。

render g.select(name:"tipo" from:['','one','two'])

Answer 2

//Build your output string as the next:
def output = g.select(name:"tipo" from:['','one','two'])
//And add any other string or tag if you need
output = "Tipo: " + output
render (text: output)
