fixture_file_upload的参数在请求规范中转到String类。

Question

下面的代码会产生一些错误。

规范/rails_helper.rb

RSpec.configure do |config|
  config.include ActionDispatch::TestProcess

  config.fixture_path = "#{::Rails.root}/spec/fixtures"

  ...
end

spec/请求/api/v1/映像_spec.rb

require 'rails_helper'

describe 'Images', type: :request do
  describe 'POST api/v1/images' do
    it 'should have status :created' do
      post api_v1_images_path(content: fixture_file_upload('test.jpg', 'image/jpeg'), position: 0), nil , nil
      # #<Rack::Test::UploadedFile:0x007f92beb9cfc8 @content_type={:content_type=>"image/jpeg"}, @original_filename="test.jpg", @tempfile=#<Tempfile:/var/folders/qv/8k9_kbs52w5ddhb1ph41xngh0000gn/T/test.jpg20140922-11520-1co5l19>>

      expect(response).to have_http_status(:created)
    end
  end
end

app/controllers/api/v1/映像_Controller.rb

def create
  puts params[:content].class #=> String
  # String..!? What's going on..!?
  #
  # I'd like to pass upload rspec with carrierwave.
  # Creating model with uploader by params[:content] will cause null value of image attributes of model.
end

对象id是相同的，但是属性消失了。发生什么事了？

Answer 1

我滥用了邮政法..。

以前：post api_v1_images_path(content: fixture_file_upload('test.jpg', 'image/jpeg'), position: 0), nil , nil

后：post api_v1_images_path, {content: fixture_file_upload('test.jpg', 'image/jpeg'), position: 0}, nil

“后”通过了规范。

Answer 2

Rails 5：

在此之前：

post api_v1_images_path params: { content: fixture_file_upload('test.jpg', 'image/jpeg'), position: 0 }

之后：

post api_v1_images_path {}, params: { content: fixture_file_upload('test.jpg', 'image/jpeg'), position: 0 }
