我从github上关注如何使用paperclip和rails进行多次上传的repo， rails-multimodel-upload-demo 。 我目前正试图让我的规格通过，但有四个错误atm。

我试图了解如何使用工厂女孩生成回形针附件？ 没有成功。 然而，模型与问题类似。
该错误提到存在nil类，因此上传不是在工厂中进行的。 即使我按照之前的“问题”答案，我也没有让它发挥作用。
cars_controller.rb
def show @cars = Car.without_car(@car).shuffle[0...3] @previous = @car.id == 1 ? Car.last : Car.find( @car\ .id - 1 ) @next = @car == Car.last ? Car.first : Car.find( @ca\ r.id + 1 ) @uploads = @car.uploads @bodyid = 'car-details' end在对我的工厂进行一些更改之后
include ActionDispatch::TestProcess FactoryGirl.define do factory :car do make "MyString" model "MyString" year 1 seats 1 transmission "MyString" drive "MyString" interior "MyString" exterior "MyString" uploads { fixture_file_upload(Rails.root.join('spec', 'photos', 'test.jpg'), 'image/jpg') } end end我得到更多错误

I followed this repo, rails-multimodel-upload-demo, from github on how to have multiple uploads using paperclip and rails. I am currently trying to make my specs pass, but there are four errors atm.

I have tried to follow How Do I Use Factory Girl To Generate A Paperclip Attachment? without success. The models are similar to the question however.
The error mentions that there there is a nil class, so the upload wasn't being made in the factory. Even when I followed the previous' questions' answers, I didn't get it to work.
cars_controller.rb
def show @cars = Car.without_car(@car).shuffle[0...3] @previous = @car.id == 1 ? Car.last : Car.find( @car\ .id - 1 ) @next = @car == Car.last ? Car.first : Car.find( @ca\ r.id + 1 ) @uploads = @car.uploads @bodyid = 'car-details' endAfter making some changes to my factories
include ActionDispatch::TestProcess FactoryGirl.define do factory :car do make "MyString" model "MyString" year 1 seats 1 transmission "MyString" drive "MyString" interior "MyString" exterior "MyString" uploads { fixture_file_upload(Rails.root.join('spec', 'photos', 'test.jpg'), 'image/jpg') } end endI get more errors
Failure/Error: let(:car) { FactoryGirl.create(:car) } ActiveRecord::AssociationTypeMismatch: Upload(#2223442800) expected, got String(#2164378420)from reading about ActiveRecord::AssociationTypeMismatch, the object is being passed into the car variable. Ruby/Rails/Rspec - ActiveRecord::AssociationTypeMismatch: I'm not sure how this exactly relates, but I'm looking into it.
最满意答案
当我以前的失败规格通过时，我正在处理上一个和下一个链接功能。 这是解决RSpec和Factory用于测试下一个，prev记录的答案
upload未定义的原因是因为let(:user)实际上没有为:user写一条记录。 一旦我添加了let!(:user) { FactoryGirl.create(:user) }一切正常
I was working on a previous and next links feature when my previous failing specs passed. This is the answer that solved it RSpec and Factory for testing next, prev records
The reason upload was not defined was because the let(:user) does not actually write a record for :user. Once I added let!(:user) { FactoryGirl.create(:user) } everything worked
