Rspec - PG :: UndefinedTable：错误：关系“应用程序”不存在

时间：2017-11-02 05:47:24

标签： ruby-on-rails ruby postgresql rspec ruby-on-rails-5

我正在尝试使用bin rails\test开始构建并运行我的rspec测试。他们过去曾经工作过，但是现在当我运行它们时，每次测试都会得到以下错误。

Error:
VenueTest#test_should_not_save_venue_without_name:
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR:  relation "application" does not exist
LINE 1: DELETE FROM "application"
                    ^
: DELETE FROM "application"

Finished in 0.382377s, 41.8435 runs/s, 0.0000 assertions/s.
16 runs, 0 assertions, 0 failures, 16 errors, 0 skips

我几乎没有写任何测试，所以它只是现在失败的预卷。

我已经尝试运行迁移（运行正常）并且确实创建了测试数据库。我也试过了：

rake db:test:prepare
rake db:test:load

但仍然得到同样的错误。我也没有名为'application'的模型，所以不知道为什么它试图从“应用程序”中删除？

我猜这是某种奇怪的配置，我一路上搞砸了，但不知道它会是什么！

所有测试都失败了，但有问题的测试是：

Home_Controller_test.rb 

require 'test_helper'

class HomeControllerTest < ActionDispatch::IntegrationTest
  test "should get index" do
    get home_index_url
    assert_response :success
  end

end

offers_controller_test.rb 

require 'test_helper'

class OffersControllerTest < ActionDispatch::IntegrationTest
  setup do
    @offer = offers(:one)
  end

  test "should get index" do
    get offers_url
    assert_response :success
  end

  test "should get new" do
    get new_offer_url
    assert_response :success
  end

  test "should create offer" do
    assert_difference('Offer.count') do
      post offers_url, params: { offer: { desc: @offer.desc, end: @offer.end, offertype: @offer.offertype, start: @offer.start } }
    end

    assert_redirected_to offer_url(Offer.last)
  end

  test "should show offer" do
    get offer_url(@offer)
    assert_response :success
  end

  test "should get edit" do
    get edit_offer_url(@offer)
    assert_response :success
  end

  test "should update offer" do
    patch offer_url(@offer), params: { offer: { desc: @offer.desc, end: @offer.end, offertype: @offer.offertype, start: @offer.start } }
    assert_redirected_to offer_url(@offer)
  end

  test "should destroy offer" do
    assert_difference('Offer.count', -1) do
      delete offer_url(@offer)
    end

    assert_redirected_to offers_url
  end
end

venues_controller_test.rb 

require 'test_helper'

class VenuesControllerTest < ActionDispatch::IntegrationTest
  setup do
    @venue = venues(:one)
  end

  test "should get index" do
    get venues_url
    assert_response :success
  end

  test "should get new" do
    get new_venue_url
    assert_response :success
  end

  test "should create venue" do
    assert_difference('Venue.count') do
      post venues_url, params: { venue: { desc: @venue.desc, exists: @venue.exists, latitude: @venue.latitude, longitude: @venue.longitude, name: @venue.name, region: @venue.region, vtype: @venue.vtype } }
    end

    assert_redirected_to venue_url(Venue.last)
  end

  test "should show venue" do
    get venue_url(@venue)
    assert_response :success
  end

  test "should get edit" do
    get edit_venue_url(@venue)
    assert_response :success
  end

  test "should update venue" do
    patch venue_url(@venue), params: { venue: { desc: @venue.desc, exists: @venue.exists, latitude: @venue.latitude, longitude: @venue.longitude, name: @venue.name, region: @venue.region, vtype: @venue.vtype } }
    assert_redirected_to venue_url(@venue)
  end

  test "should destroy venue" do
    assert_difference('Venue.count', -1) do
      delete venue_url(@venue)
    end

    assert_redirected_to venues_url
  end
end

修改

根据要求在下面进行Stacktrace：

编辑 - 添加了Venue_test.rb 

require 'test_helper'

class VenueTest < ActiveSupport::TestCase
  # test "the truth" do
  #   assert true
  # end

  test "should not save venue without name" do
    venue = Venue.new
    assert_not venue.save, "Saved the venue without a title"
  end


end

以防其他人看到此问题，test / fixtures文件夹中有额外的文件（可能由生成器创建）。 @dskecse确定了这个问题。

删除后，脚本运行正常。

在以下命令中运行对我来说解决了该错误：

RAILS_ENV=test rake db:test:prepare
