Ruby on rails Rails api后期测试不允许我访问json对象

我花了很长时间试图弄清楚我的用户控制器的帖子行为在哪里出了问题，我已经没有主意了

在命令行中键入json后，我从binding pry返回了错误：

{“message”=>“找不到没有ID的用户”}

这很奇怪，因为我只是在创建一个新用户。控制器

user_参数

与在测试环境中创建的

valid_属性

有效负载匹配

移除绑定。撬动我收到此错误：

 1) Users API POST /users when the request is valid creates a user
     Failure/Error: expect(json['username']).to eq('Tychus')

       expected: "Tychus"
            got: nil

       (compared using ==)

我最初的GET测试似乎是有效的，所以我不知道为什么我的帖子会出错

任何帮助都将不胜感激

问题在于

设置用户

私有方法，它试图查找

id

。删除

：在执行操作之前从
中创建
