多个要求 &允许强参数 rails 4 [英] Multiple require & permit strong parameters rails 4

问题描述

在以下情况下，我尝试使用强参数.我想要求 email_address, password 并允许 remember_me 字段.

In the below case, i am trying to use strong parameters. I want to require email_address, password and permit remember_me fields.

但是在下面使用它只允许方法中的 LAST 行 示例:- 在下面的情况下，它只需要 params.permit(:remember_me)

But using like below it only allows the LAST line in the method Ex:- In below case it only take params.permit(:remember_me)

  private

  def registration_params
    params.require(:email_address)
    params.require(:password)
    params.permit(:remember_me)
  end

另一个例子:-在下面的例子中，如果我像下面那样重新排列它只会需要 params.require(:email_address) 我哪里出错了?

Another Ex:- In this below case, if i rearrange it like below it will take only params.require(:email_address) where am i going wrong ?

  def registration_params
    params.require(:password)
    params.permit(:remember_me)
    params.require(:email_address)
  end

更新参数散列就像

{
              "utf8" => "✓",
     "email_address" => "[e-mail]",
          "password" => "password123",
       "remember_me" => "true",
            "commit" => "Log in",
        "controller" => "registration",
            "action" => "sign_in"
}

推荐答案

好的通过朋友找到了答案...一种方法是

Ok found the answer through a friend ...one way to do this is

params.require(:email_address)
params.require(:password)
params.permit(
:email_address,
:password,

)

效果很好.
