我使用
添加了用户模型的订购default_scope order: 'users.surname ASC'
一切正常。
然后我想在我的 spec / models / user_spec.rb 文件中添加一个测试用例。
不幸的是,它会出错。虽然,也有类似的测试,但它们运行良好。
以下是exerpts:
require 'spec_helper'
describe User do
before do
@user = User.new(name: 'Example', surname: 'User', email: 'user@example.com',
password: 'foobar', password_confirmation: 'foobar')
end
subject { @user }
describe "remember token" do
before { @user.save }
its(:remember_token) {should_not be_blank}
end
describe "users ordered by surname" do
before do
@user2 = User.create(name: 'Roy', surname: 'McAndy', email: 'pam@exam.com',
password: 'foobar', password_confirmation: 'foobar')
@user3 = User.create(name: 'Roy', surname: 'Andyman', email: 'pamjim@ex.com',
password: 'foobar', password_confirmation: 'foobar')
end
pp User.all
pp [@user3, @user2]
User.all.should == [@user3, @user2]
end
describe "with role set to admin" do
before do
@user.save!
@user.update_attribute(:role, "admin")
end
it { should be_admin }
end
在上述Rspec文件中,描述“按姓氏排序的用户”会出现以下错误:
bundle exec rspec
[]
[nil, nil]
/home/xxx/.rvm/gems/ruby-1.9.3-p429/gems/rspec-expectations-2.13.0/lib/rspec/expectations/fail_with.rb:32:in `fail_with': expected: [nil, nil] (RSpec::Expectations::ExpectationNotMetError)

我使用漂亮的印刷品(pp)进行追踪。
奇怪的是,在其他情况下 user.save!工作正常。
我的错误在哪里,这里可能出现什么问题?
非常感谢!

问题是你没有在it
块内执行测试操作,但你应该这样做。 e.g:
describe 'default scope' do
before do
@user2 = User.create(name: 'Roy', surname: 'McAndy', email: 'pam@exam.com',
password: 'foobar', password_confirmation: 'foobar')
@user3 = User.create(name: 'Roy', surname: 'Andyman', email: 'pamjim@ex.com',
password: 'foobar', password_confirmation: 'foobar')
end
it 'should order by surname' do
User.all.should == [@user3, @user2]
end
end
