ruby-on-rails – 未定义的方法’env’为nil:NilClass

前端之家收集整理的这篇文章主要介绍了ruby-on-rails – 未定义的方法’env’为nil:NilClass前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
这是我的spec文件看起来像:spec / api / v1 / projects_spec.rb
require "spec_helper"

describe "/api/v1/projects",:type => :api do
  context "projects viewable by this user" do
   it "JSON" do
   end
  end
end

它包含了很多,但我删除了很多行在尝试找不到这样的错误

Failure/Error: Unable to find matching line from backtrace
NoMethodError: undefined method `env' for nil:NilClass

这段代码来自Ryan Bigg的“Rails 3 in Action”.唯一的其他文件包括:spec / support / api / helper.rb

module ApiHelper
  include Rack::Test::Methods

  def app
   Rails.application
  end
end

RSpec.configure do |c|
  c.include ApiHelper,:type => :api
end

我一直在尝试google过去1小时的错误,最近发现的是this,结果我删除了使用Devise :: Test_Helpers的代码.可悲的是,它还是不行.

任何帮助将不胜感激.非常感谢.

解决方法

你仍然在Devise :: TestHelpers的某个地方.检查看看是什么“spec_helper”正在加载.
