Michael Hartl 的教程第 10.2.2 章，列出 10.26 测试失败

Question

浏览了 Hartl 的教程并搜索了答案，但没有找到答案。（可能存在答案，但由于章节已在较新版本中更新和切换，如果存在，我找不到它们。

我在 10.2.2 节。 清单 10.26 做 Rails 测试。

这是我测试的错误：

end

为什么当书上说所有测试都应该通过时，我得到了 2 次失败的测试？我已经查看了错误消息提到的行，但我不确定出了什么问题。感谢您的帮助。

编辑：会话控制器

class SessionsController < ApplicationController
  def new
  end
  def create
    @user = User.find_by(email: params[:session][:email].downcase)
    if @user && @user.authenticate(params[:session][:password])
    log_in @user
    params[:session][:remember_me] == '1' ? remember(@user) : forget(@user) 
    redirect_to @user
    else
    flash.now[:danger] = 'Invalid email/password combination' # Not quite right!
    render 'new'
    end
  end
  def destroy
    log_out if logged_in?
    redirect_to root_url
  end
end

Answer 1

您在"Sterling Archer"测试夹具的password_digest中缺少一个右尖括号。

password_digest: <%= User.digest('password') %

应该是

password_digest: <%= User.digest('password') %>

Answer 2

更仔细地查看行：

BCrypt::Errors::InvalidHash: invalid hash
            app/controllers/sessions_controller.rb:9:in `create'

您没有指定此控制器的代码，我无法告诉您可能出了什么问题。
