ruby-on-rails - FactoryGirl 的唯一性验证失败

Question

我在使用 FactoryGirl 时遇到问题，我正在使用序列来避免重复字段，但无论如何验证都失败了。

输出:

  1) CustomersController anonymous user GET #edit is redirected to signin when accessing edit form
     Failure/Error: get :edit, id: create(:customer)
     ActiveRecord::RecordInvalid:
       Validation failed: Email has already been taken, Email has already been taken
     # ./spec/controllers/customers_controller_spec.rb:25:in `block (4 levels) in <top (required)>'
     # -e:1:in `<main>'

  3) Customer public class methods executes its methods correctly #find_by_id_or_name finds customer by name
     Failure/Error: let(:john) {create(:customer, name: 'John Doe X')}
     ActiveRecord::RecordInvalid:
       Validation failed: Email has already been taken, Email has already been taken
     # ./spec/models/customer_spec.rb:25:in `block (3 levels) in <top (required)>'
     # ./spec/models/customer_spec.rb:38:in `block (5 levels) in <top (required)>'
     # -e:1:in `<main>'

工厂:

FactoryGirl.define do
  factory :customer do
    user
    name {Faker::Name.name}
    sequence(:mail) { |n| "person#{n}@example.com" }
    address {Faker::Address.street_address}
    phone {Faker::PhoneNumber.phone_number}
  end
end

FactoryGirl.define do
  factory :user do
    sequence(:email) {|i| "example#{i}@example.com"}
    password {Faker::Internet.password(10)}
  end
end

这些是失败的测试:

RSpec.describe Customer, type: :model do
    describe "public class methods" do
        let(:john) {create(:customer, name: 'John Doe X')}
        let(:frank) {create(:customer)}


    context "responds to its methods" do
      it "responds to #find_by_id_or_name" do
        expect(Customer).to respond_to(:find_by_id_or_name)
      end
    end

    context "executes its methods correctly" do
      context "#find_by_id_or_name" do
        it "finds customer by name" do
          customer = Customer.find_by_id_or_name('John Doe X')
          expect(customer).to eq john
        end
        it "finds customer by id" do
          customer = Customer.find_by_id_or_name(frank.id)
          expect(customer).to eq frank
        end
      end
    end
  end
end



RSpec.describe CustomersController, type: :controller do
  context "signed in user" do
    before :each do
      @user = create(:user)
    end
    describe "GET #edit" do
      it "renders :edit view" do
        get :edit, id: create(:customer).id
        expect(response).to render_template(:edit)
      end
    end

    describe "DELETE #destroy" do
      before :each do
        @customer = create(:customer, user: @user)
      end
      it "deletes record" do
        expect {delete :destroy, id: @customer.id}.to change(Customer, :count).by(-1)
      end
    end
  end
end

这在我的应用程序中发生在我身上。我只是复制了一些适用于客户的测试。

谢谢

我的问题与没有适当配置 database_cleaner 有关。本帖中的配置解决了问题:How can I clean my database between erroneous rspec specs?
