如何在Rails中有条件地显示局部

Question

如何在Rails中动态显示局部视图？

我正在尝试这样的事情：

def showdata(summary)
    blah = 'test'
    if summary
        partial('partial1', locals: { blah })
    else
        partial('partial2', locals: { blah })
    end

我对Rails非常陌生：-（

Answer 1

您可以使用渲染（this is the reference），下面是示例代码

def showdata(summary)
    blah = 'test'
    if summary
        render('partial1', locals: { blah })
    else
        render('partial2', locals: { blah })
    end
end

Answer 2

也可以：

render partial: "partial1", locals: { blah } if summary
render partial: "partial2", locals: { blah } if !summary

或使用三元运算符

render partial: summary? "partial1" : "partial2", locals: { blah }
