我有以下型号:
class Face < ActiveRecord::Base
attr_accessible :face_index, :design, :background
belongs_to :template
mount_uploader :background, BackgroundUploader
end
BackgroundUploader:
class BackgroundUploader < CarrierWave::Uploader::Base
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
end
当我启动rails控制台时,我可以创建一个Face并为其保存背景:
f = Face.create(:face_index => 0)
f.background = File.open("/path/to/image.jpg")
f.save!
这一切都有效,但当我尝试将其移至rspec时,我遇到了失败:
Failures:
1) Face A new face
Failure/Error: @face.background = File.open(image_path)
NoMethodError:
undefined method `background_will_change!' for #<Face:0x007ff63d9f7410>
规范:
describe Face do
before(:each) do
image_path = Rails.root.join('spec/support/images', '02.jpg').to_s
@face = FactoryGirl.create(:face)
@face.background = File.open(image_path)
@face.save!
end
describe "A new face" do
it { should belong_to(:template) }
end
end
工厂:
FactoryGirl.define do
factory :face do
face_index 0
end
end
我在数据库中缺少上传器列之前就已经看到了这个错误,但如果我的迁移对于dev是正确的,那么它们应该是正确的测试,非?我是否需要在规范中要求使其有效?
谢谢!

Doh,答案是我的最后一段,我忘了跑
rake db:test:load
休息并回到问题的一个很好的例子。
