Question

我无法让我的本地变量在标签之间切换。本地设置在使用该表单的每个选项卡下的h3标记下。从那里，本地传递给类别变量，因此我的表单可以将其用作部分变量。目前，无论选择哪个标签，它都只会拉动第一个局部变量“Associates”。

有没有办法确保类别变量根据所选的标签获取传递给它的正确本地？

提前致谢。

Answer 1

在_form部分内容中，您需要将category引用为category，而不是@category。

此外，local应为locals，我认为您必须使用render密钥呼叫partial以传入本地，例如：

render partial: 'best_practices/form', locals: {category: @order}

Answer 2

_form.html.erb需要简单地使用category而不是@category。

对于您的company.html.erb，请尝试

 <%= render 'best_practices/form', :category => @associate %>

这会将@associate分配给:category变量，另一方面可以将其作为简单category进行访问。

为什么我的局部变量不会随着标签的变化而改变？
