我是 Rails 新手，目前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，因为显然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，或者没有保留。
我得到的错误是
Failure/Error: select community.name, :from => "deal[community_id]"
Capybara::ElementNotFound:
Unable to find option "Community7"
这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之后清理数据库记录。无论出于何种原因，这件事都给我带来了很多麻烦。
