Question

所以我有一个属于User的问题模型。最初，我想用属性public：true设置基本问题，每个用户都可以看到我想在seed.rb中创建的这类问题。

然后，随后使用Answer模型。每个用户回答都属于某个问题。

现在问题是为用户创建这些预先提出的问题以回答我在seed.rb中尝试了以下内容：

u = User.new(email: "test@gmail.com", password: "testpass", password_confirmation: "testpass", gender: "M")
questions = u.questions.build(title: "What is your favourite food?")
u.save

我想使用

为视图中的所有用户调用相同的默认问题

questions_controller.rb

def index 
  @questions = Question.all
end

但这似乎没有用，即当我去rails c并运行u时，它是一个未定义的方法..而且u.questions是一个空数组。我手动在控制台中运行这些线路并且它们工作，所以我不确定这里发生了什么。

我做错了什么？

我认为问题在于OP在开发数据库中存在错误的数据。

正在运行rake db:drop db:create db:setup似乎解决了这个问题。
