我是Rails的新手，我正在尝试为提交表单编写测试。它应该测试表单是否可以为Deal模型创建新记录。它失败了，因为我试图创建的社区对象实际上并没有出现在下拉列表中。我想知道是否由于某种原因没有创建记录，或者没有坚持。
我得到的错误是
Failure/Error: select community.name, :from => "deal[community_id]"
Capybara::ElementNotFound:
Unable to find option "Community7"
以下是我的规范的相关部分：
describe "Deal Pages" do
subject {page}
describe "create Deal" do
let(:user) { FactoryGirl.create :user, username: "user_1", email: "user_1@email.com", password: "password" }
let(:community) { FactoryGirl.create :community, name: "Community7", title: "Community 7", description: "A great community", user: user }
before(:each) do
sign_in user
visit new_deal_path
end
let(:submit) { "Submit Deal" }
describe "with invalid information" do
it "should not create a Deal" do
expect { click_button submit }.not_to change(Deal, :count)
end
describe "after submission" do
before { click_button submit }
it { should have_title('Submit A New Deal') }
it { should have_content('error') }
end
end
describe "with valid information" do
it "should create a Deal" do
fill_in "Title", with: "A New Deal"
select community.name, :from => "deal[community_id]"
fill_in "Url", with: "http://www.amazon.com"
fill_in "Description", with: "This is the best Deal!"
expect { click_button submit }.to change(Deal, :count).by(1)
end
end
end
我正在使用database_cleaner gem，我知道配置它会在每个示例后清理db记录。无论出于何种原因，这件事只是给了我很多麻烦。

好的，我想了一会儿，因为我讨厌通过谷歌找到未回答的问题时，我会跟进。
问题是我在父母描述块的顶部有以下内容：
let(:community) { FactoryGirl.create :community, name: "Community7", title: "Community 7", description: "A great community", user: user }
除了不需要指定单个属性之外，问题在于当与database_cleaner配置结合使用时，它会在每个示例之后转储数据库。在“创建交易”块之前有一个或多个示例，因此在调用community.name时，社区表中没有数据。我把我的规格改为如此，我觉得我更容易处理和遵循：
describe "create Deal" do
before(:each) do
@user = FactoryGirl.create :user
@community = FactoryGirl.create :community
sign_in @user
visit new_deal_path
end
let(:submit) { "Submit Deal" }
describe "with invalid information" do
it "should not create a Deal" do
expect { click_button submit }.not_to change(Deal, :count)
end
describe "after submission" do
before { click_button submit }
it { should have_title('Submit A New Deal') }
it { should have_content('error') }
end
end
describe "with valid information" do
it "should create a Deal" do
fill_in "Title", with: "A New Deal"
select @community.name, :from => "deal[community_id]"
fill_in "Url", with: "http://www.amazon.com"
fill_in "Description", with: "This is the best Deal!"
expect { click_button submit }.to change(Deal, :count).by(1)
end
end
end
before（：each）确保在每个子示例运行之前我获得一个新的用户和社区对象。希望这有助于某人，但如果不是这对我来说是一次学习经历。

问题是您在
中传递了“Community7”let(:community) { FactoryGirl.create :community, name: "Community7", title: "Community 7", description: "A great community", user: user }
虽然“社区”一词也是通过工厂添加的：社区：
factory :community do
sequence(:name) { |n| "Community#{n}" }
sequence(:title) { |n| "Community #{n} Title" }
...
end
结果你得到了“CommunityCommunity7”和相应的错误：
Unable to find option "Community7"
我会将工厂调整为
factory :community do
sequence(:name) { |n| "#{n}" }
sequence(:title) { |n| "#{n} Title" }
...
end
