失败/错误:登录用户未定义方法`sign_in' [英] Failure/Error: sign_in user undefined method `sign_in'

问题描述

我被困在 Rails 教程的第 9 章 - 更具体地说是在第 9.1 节的末尾.我的问题类似于这个线程中的问题，但是那里的解决方案对我不起作用.

I'm stuck at Chapter 9 in the Rails tutorial - more specifically at the end of section 9.1. My problem is similar to the one in this thread but the solution there didn't work for me.

这是我的 user_pages_spec.rb:

Here is my user_pages_spec.rb:

require 'spec_helper'
describe "User pages" do
subject { page }

describe "signup page" do
before { visit signup_path }

it { should have_content('Sign up') }
it { should have_title(full_title('Sign up')) }
end

describe "profile page" do
let (:user) {FactoryGirl.create(:user)}
before { visit user_path(user) }

it { should have_content(user.name) }
it { should have_title(user.name) }
end

describe "signup" do

before { visit signup_path }

let(:submit) { "Create my account" }

describe "with invalid information" do
  it "should not create a user" do
    expect { click_button submit }.not_to change(User, :count)
  end
end

describe "with valid information" do
  before do
    fill_in "Name",         with: "Example User"
    fill_in "Email",        with: "[e-mail]"
    fill_in "Password",     with: "foobar"
    fill_in "Confirmation", with: "foobar"
  end

  it "should create a user" do
    expect { click_button submit }.to change(User, :count).by(1)
  end
end
end

describe "edit" do
let(:user) { FactoryGirl.create(:user)}
before do
  sign_in user
  visit edit_user_path(user)
end

describe "page" do
  it { should have_content("Update your profile")}
  it { should have_title("Edit user")}
  it { should have_link('change', href:'http://gravatar.com/emails')}
end

describe "with invalid information" do
  before { click_button "Save changes"}

  it { should have_content('error') }
end

describe "with valid information" do
  let(:new_name) { "New Name"}
  let(:new_email) {[e-mail]}
  before do
    fill_in "Name", with: new_name
    fill_in "Email", with: new_email
    fill_in "Password", with: user.password
    fill_in "Confirm Password", with: user.password
    click_button "Save changes"
  end

  it {should have_title(new_name)}
  it {should have_selector('div.alert.alert-success')}
  it {should have_link('Sign out', href: signout_path)}
  specify {expect(user.reload.name).to eq new_name}
  specify {expect(user.reload.email).to eq new_email}
end
end
end

错误信息如下:

bundle exec rspec spec/
.............................................FFFFFFFFF

Failures:

 1) User pages edit page 
 Failure/Error: sign_in user
 NoMethodError:
   undefined method `sign_in' for #<RSpec::Core::ExampleGroup::Nested_4::Nested_4::Nested_1:0x007faa37859d80>
 # ./spec/requests/user_pages_spec.rb:49:in `block (3 levels) in <top (required)>'

这是我的规范/support/utilities.rb:

And here is my spec/support/utilities.rb:

def full_title(page_title)
base_title = "Ruby on Rails Tutorial Sample App"
if page_title.empty?
base_title
else
"#{base_title} | #{page_title}"
end
end

def sign_in (user, options={})
if options[:no_capybara]
# Sign in when not using Capybara
remember_token = user.new_remember_token
cookies[:remember_token]
user.update_attribute(:remember_token, User.digest(remember_token))
else
visit signin_path
fill_in "Email", with: user.email
fill_in "Password", with: user.password
click_button "Sign in"
end
end

有什么建议吗?

推荐答案

我在尝试安装 rcov 时确实运行了 bundle install(Rubymine 抱怨缺少它).安装失败，因为 rcov 不适用于我的 Rails 版本.没关系.

I did run bundle install while I was trying to install rcov (Rubymine was complaining about its lack). The installation failed as rcov is not available for my version of rails. That's fine.

真正奇怪的是，之后我重新运行了测试，一切正常.没有任何错误消息的痕迹.我是一个 rails noob 但这有点丰富 - 失败的捆绑安装不会改变任何东西.我观察到的错误消息没有任何原因，现在它无缘无故地消失了.

The really bizarre thing is that afterwards I re-ran the tests and everything worked. There was no trace of the error message. I am a rails noob but this is a bit rich - a failed bundle install shall not change anything. There was no reason for the error message I observed and now it disappeared without any reason.

==我意识到问题是 rails 似乎没有在测试之间清空缓存(在我看来，这是一个可怕的错误).默认情况下，它无法重新读取文件，因此可能会忽略已发生的更改.我在这里提供了更多详细信息:Rails 教程:未定义的方法

== I realised the problem is that rails does not seem to empty the cache between tests (which is, in my opinion, a scary bug). By default it fails to re-read the files and thus may ignore changes that have occurred. I put more details here: Rails tutorial: undefined method
