动态键的强参数

Question

下面是我的参数，如何为此编写强参数？

"foo" => {"54" => {"name" => "test", "age" => "10"}, "93" => {"name" => "test3", "age" => "20"}}

无论如何还要写下一个以外的吗？

def foo_params
  params.permit(foo: [:name,:age])
end

Answer 1

你可以试试这个

params.permit(foo: [:name, :age]).require(:foo)

Answer 2

你可以试试这个：

params.permit(:foo => {"54" => [:name, :age], "93" => [:name, :age]})

Answer 3

在我的情况下，我有params

"products"=>{"0"=>{"title"=>"item1", "price"=>"123123"}, "1"=>{"title"=>"item2", "price"=>"123123"}}

我尝试了什么

params.require(:products).permit =>

Unpermitted parameters: :0, :1
<ActionController::Parameters {} permitted: true>

解

params.require(:products).permit! =>

<ActionController::Parameters {"0"=><ActionController::Parameters {"title"=>"item1", "price"=>"123123"} permitted: true>, "1"=><ActionController::Parameters {"title"=>"item2", "price"=>"123123"} permitted: true>} permitted: true>
