Ruby on rails 用户登录后，为什么要设计重定向到视图中的Sign_而不是指定的路径？

我对设计重定向有问题。默认情况下，在用户登录并注册后，它将重定向到toroot_路径。我想将该路径更改为播放列表路径

每次我运行测试时，它都会失败，并转到路径中的用户/签名处，我不知道为什么。我已经厌倦了在Stackoverflow和Github上找到的不同解决方案，但没有任何效果。可能是解决方案很明显，我看不到，或者我的测试写得不好。奇怪的是，注册规范通过了，但是每次注册规范都失败了。我需要另一只眼睛和帮助

更新***

基于Sevensacat的评论，我更新了下面的测试，但仍然得到相同的结果

路线

会话新

spec/factories/users.rb

规格/特性/注册规格。rb此规格良好且合格

require 'spec_helper'
feature "Sign up as a user" do

  scenario "with an email address" do
    user = FactoryGirl.build(:user)
    visit root_path
    click_link "Create Account"

    fill_in "Email", with: user.email
    fill_in "Password", with: user.password
    fill_in "Password confirmation", with: user.password_confirmation
    click_button "Sign up"

    expect(current_path).to eq playlists_path 
    expect(page).to have_css '.alert',          text: 'Welcome! You have signed up successfully.'  
    expect(page).to have_link 'Sign out',       href: destroy_user_session_path
    expect(page).to have_link 'Edit profile',   href: edit_user_registration_path
  end
end

spec/features/sign_in_spec.rb此规范不好且失败

require 'spec_helper'
feature "Sign in as a user" do

  scenario "with an email address and password" do
    user = FactoryGirl.create(:user)
    visit root_path
    click_link "Sign in"

    fill_in "Email", with: user.email
    fill_in "Password", with: user.password
    click_button "Sign in"

    expect(current_path).to eq playlists_path
    expect(page).to have_css '.alert',          text: 'Signed in successfully.'    
    expect(page).to have_link 'Sign out',       href: destroy_user_session_path
    expect(page).to have_link 'Edit profile',   href: edit_user_registration_path
  end
end

当我在_spec.rb中运行rspec spec/features/sign_时，它失败：

Failures:

  1) Sign in as a user with an email address and password
     Failure/Error: expect(current_path).to eq playlists_path

       expected: "/playlists"
            got: "/users/sign_in"

       (compared using ==)
     # ./spec/features/signin_spec.rb:11:in `block (2 levels) in <top (required)>'

奇怪的是，虽然我的sign_in_规范失败了，但当我运行应用程序时，它运行良好，并且在登录和注册后重定向到播放列表路径

---

为什么要设计这种奇怪的重定向，或者为什么我的测试失败？

登录规范中是否存在该用户？很可能，您需要在该规范的设置中使用该电子邮件和密码创建用户

---

规范通常单独运行，并且在测试之间删除所有数据-如果在运行规范时依赖数据，则需要在规范中进行设置。

执行以下操作：

bundle exec rake db:drop RAILS_ENV=test
bundle exec rake db:create RAILS_ENV=test
bundle exec rake db:schema:load RAILS_ENV=test

改变

user=FactoryGirl.create:user

到

user=FactoryGirl.build:user

我的考试通过了

FactoryGirl.define do
    sequence(:email) { |n| "someone#{n}@example.com" }

    factory :user do
      email
      password 'password'
      password_confirmation { |u| u.password }
  end
end
