我询问我的Rspec测试如下。
Rspec - RuntimeError: Called id for nil, which would mistakenly be 4
在相同的代码（“items_controller.rb”的Rspec测试）上，我正在尝试进行“PUT更新”测试。但是我收到错误“Paperclip :: AdapterRegistry :: NoHandlerError：找不到”＃“的处理程序。
我的Rspec测试如下。老实说，我猜这个失败的原因是“”照片“=＆gt; File.new（Rails.root +'app / assets / images / rails.png'）”on“let（：valid_attributes）”。但是，我尝试了几种方法，但我无法修复。 顺便说一句，我的rails版本是“Rails 3.2.14”。然后我试着跟帖，但也不能。
Can't figure out what's causing my tests to fail
错误如下。
......F....

我想得到某人的建议。提前谢谢。

尝试使用Rack::Test::UploadedFile代替File.new
require 'rack/test'
Rack::Test::UploadedFile.new('fixtures/test_file.png', 'image/png')

我非常确定你的问题在于视图中的form_for， 尝试这样的事情：
<%= form_for @restaurante, :html => { :multipart => true } do |form| %>
Nome:<%= form.text_field :nome%>
Endereço:<%= form.text_field :endereco %>
Especialidade:<%= form.text_field :especialidade %>
Foto:<%= form.file_field :foto %>
<%= form.submit 'create'%>
<% end %>
