我为创建动作创建一个Rspec控制器测试,该动作获取两个对象,故事和ku的参数。故事验证了title和large_cover_url的存在。不确定为什么rspec在传递无效参数时会引发参数错误,并且可以对此问题使用一些见解。
这是错误:
Failure/Error: post :create, story: {title: nil, large_cover_url: "present"}, ku: Fabricate.attributes_for(:ku)
ArgumentError:
wrong number of arguments (0 for 2)
# ./app/controllers/stories_controller.rb:18:in `create'
# ./spec/controllers/stories_controller_spec.rb:59:in `block (4 levels) in <top (required)>'
以下是规范:
context "failed story creation" do
let(:bob) { Fabricate(:user) }
before { sign_in_user(bob) }
it "does not create a new story" do
post :create, story: {title: nil, large_cover_url: "present"}, ku: Fabricate.attributes_for(:ku)
expect(Story.count).to eq(0)
end
end
以下是控制器操作:
def create
@story = Story.new(params[:story])
@ku = Ku.new(params[:ku])
if @story.save && @ku.save
@story.update_column(:user_id, current_user.id)
@ku.update_column(:user_id, current_user.id)
@story.kus << @ku
redirect_to story_path(@story), flash: {success: "Your story was published."}
else
flash[:error] = "#{@story.errors.full_message.join(', ')}"
render :new
end
end
答案 0 :(得分:1)
方法full_message
接受属性名称和错误字符串作为参数,因此当您执行flash[:error] = "#{@story.errors.full_message.join(', ')}"
时,您正在调用full_message
而没有任何参数。
您应该使用full_messages
来返回包含所有错误消息的数组。
