Rails测试错误ActiveRecord :: Fixture :: FixtureError

Question

我目前正在学习Rails教程。当我在第10章进行了Rails测试时，出现了此错误。 我可以用ruby gem'faker'造很多假用户。 但是，似乎db没有users.yml的提示。 我认为这就是在进行Rails测试时发生错误的原因。

UsersControllerTest#test_should_get_new:
ActiveRecord::Fixture::FixtureError: table "users" has no column named "lana".

我命令

rails db:reset
rails db:seed

test / fixtures / users.yml

michael: 
  name: Michael Example
  email: michael@example.com
  password_digest: <%= User.digest('password') %>
  admin: true
  activated: true
  activated_at: <%= Time.zone.now %>

archer:
  name: Sterling Archer
  email: duchess@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

  lana:
  name: Lana Kane
  email: hands@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

malory:
  name: Malory Archer
  email: boss@example.gov
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>

<% 30.times do |n| %>
user_<%= n %>:
  name:  <%= "User #{n}" %>
  email: <%= "user-#{n}@example.com" %>
  password_digest: <%= User.digest('password') %>
  activated: true
  activated_at: <%= Time.zone.now %>
<% end %>

您的缩进是错误的，为此请更改lana部分：
