grails从属性创建模型

在gsp中，我将参数传递给taglib，如下所示：

        <g:oneColumnSelect fieldName="gender" from="${['F', 'M']}"
                           valueMessagePrefix="applicant.gender"
                           value="${command?.gender}" noSelection="${['':'No answer...']}" />

class FormsTagLib {

def oneColumnSelect = {attrs, body ->
    out << render(template:"/common/wizard/formselect",
            model:[
                    fieldName:attrs.fieldName,
                    from:attrs.from,
                    valueMessagePrefix:attrs.valueMessagePrefix,
                    optionValue:attrs.optionValue,
                    value:attrs.value,
                    noSelection:attrs.noSelection
            ])
}

在taglib中，我将参数分配给一个模型，然后将该模型传递给gsp模板，如下所示：

        <g:oneColumnSelect fieldName="gender" from="${['F', 'M']}"
                           valueMessagePrefix="applicant.gender"
                           value="${command?.gender}" noSelection="${['':'No answer...']}" />

class FormsTagLib {

def oneColumnSelect = {attrs, body ->
    out << render(template:"/common/wizard/formselect",
            model:[
                    fieldName:attrs.fieldName,
                    from:attrs.from,
                    valueMessagePrefix:attrs.valueMessagePrefix,
                    optionValue:attrs.optionValue,
                    value:attrs.value,
                    noSelection:attrs.noSelection
            ])
}

类FormsTagLib{
def oneColumnSelect={attrs，body->
out也许可以帮助您：

def first = [a: 1, b: 2]
def second = [c:3]
second.putAll(first)
println second // prints [c:3, a:1, b:2]

只是打电话

 render(template:"/common/wizard/formselect", model:attrs)

应该这样做！玩得开心！
所以只要
渲染（模板：“/common/wizard/formselect”，model:attrs）
不起作用？你有错误吗？哇，是的。我已经学习grails 3周了，谢谢你的帮助。酷：-）把它作为一个答案添加进来。很高兴我能帮上忙：-）或
