Michael Hartl 重设密码错误

Question

我无法通过密码重置测试。它显示以下内容：

 1) Error:
 PasswordResetsTest#test_password_resets:
 NoMethodError: undefined method `[]' for nil:NilClass
app/controllers/password_resets_controller.rb:10:in `create'
test/integration/password_resets_test.rb:14:in `block in <class:PasswordResetsTest>'

我不确定是什么导致了零。请帮忙。

密码重置控制器

class PasswordResetsController < ApplicationController
  before_action :get_user,         only: [:edit, :update]
  before_action :valid_user,       only: [:edit, :update]
  before_action :check_expiration, only: [:edit, :update]    # Case (1)

  def new
  end

  def create
    @user = User.find_by(email: params[:password_reset][:email].downcase)
    if @user
      @user.create_reset_digest
      @user.send_password_reset_email
      flash[:info] = "Email sent with password reset instructions"
      redirect_to root_url
    else
      flash.now[:danger] = "Email address not found"
      render 'new'
    end
  end

  def edit
  end

  def update
    if params[:user][:password].empty?                  # Case (3)
      @user.errors.add(:password, "can't be empty")
      render 'edit'
    elsif @user.update_attributes(user_params)          # Case (4)
      log_in @user
      flash[:success] = "Password has been reset."
      redirect_to @user
    else
      render 'edit'                                     # Case (2)
    end
  end

  private

    def user_params
      params.require(:user).permit(:password, :password_confirmation)
    end

    # Before filters

    def get_user
      @user = User.find_by(email: params[:email])
    end

    # Confirms a valid user.
    def valid_user
      unless (@user && @user.activated? &&
              @user.authenticated?(:reset, params[:id]))
        redirect_to root_url
      end
    end

    # Checks expiration of reset token.
    def check_expiration
      if @user.password_reset_expired?
        flash[:danger] = "Password reset has expired."
        redirect_to new_password_reset_url
      end
    end
end

密码重置测试

您的 app/controllers/password_resets_controller.rb 文件中缺少 @user.update_attribute(:reset_digest, nil)。使用以下内容更新您的文件。

class PasswordResetsController < ApplicationController
  before_action :get_user,         only: [:edit, :update]
  before_action :valid_user,       only: [:edit, :update]
  before_action :check_expiration, only: [:edit, :update]    # Case (1)

  def new
  end

  def create
    @user = User.find_by(email: params[:password_reset][:email].downcase)
    if @user
      @user.create_reset_digest
      @user.send_password_reset_email
      flash[:info] = "Email sent with password reset instructions"
      redirect_to root_url
    else
      flash.now[:danger] = "Email address not found"
      render 'new'
    end
  end

  def edit
  end

  def update
    if params[:user][:password].empty?                  # Case (3)
      @user.errors.add(:password, "can't be empty")
      render 'edit'
    elsif @user.update_attributes(user_params)          # Case (4)
      log_in @user
      @user.update_attribute(:reset_digest, nil)
      flash[:success] = "Password has been reset."
      redirect_to @user
    else
      render 'edit'                                     # Case (2)
    end
  end

  private

    def user_params
      params.require(:user).permit(:password, :password_confirmation)
    end

    # Before filters

    def get_user
      @user = User.find_by(email: params[:email])
    end

    # Confirms a valid user.
    def valid_user
      unless (@user && @user.activated? &&
              @user.authenticated?(:reset, params[:id]))
        redirect_to root_url
      end
    end

    # Checks expiration of reset token.
    def check_expiration
      if @user.password_reset_expired?
        flash[:danger] = "Password reset has expired."
        redirect_to new_password_reset_url
      end
    end
end

按照提示更新，即可看到绿色测试。

我查看了 Hartl 的来源，他有这样一行：

post password_resets_path, password_reset: { email: @user.email }

而你的是

post password_resets_path, params: { password_reset: { email: @user.email }}

这是与 Rails 5 兼容的新语法。上面的解是Rails 4.
