Rails的4个强项：使它们有条件吗？ [英] rails 4 strong params: make them conditional?

问题描述

有没有办法使strong_params有条件？
不需要编写2个单独的方法吗？如果某个条件为真时要在许可列表中添加某些属性，则

Is there a way to make strong_params conditional? Without the need to write 2 separate methods? In case where one would like to add certain attributes to the permit list when a certain condition is true

例如：

devise_parameter_sanitizer.for(:user) {|u| u.permit(:user,
                                                    :email,
                                                    :role,
                                                    )}

我在上面的示例中具有此：role属性。我只希望在Rails.env.development中允许使用此属性？

I have this :role attribute permitted in above example. I only want this attribute to be permitted when in Rails.env.development is there a way to do this?

推荐答案

Haven'找不到解决方案，所以我制作了2个方法并调用正确的param方法来处理记录。

Haven't found a solution, so I made 2 methods and call the correct param method to handle the records.
