Rails 迁移错误：参数数量错误

Question

我刚刚克隆了一个存储库，所以我试图在本地设置，每当我运行rails db:migrate 时都会收到这个奇怪的错误，我已经搜索了一个解决方案，但这里没有一个能满足我的需要。

我对此感到特别困惑，因为这是我第一次使用 rails 6.0，我无法判断这是 rails 的问题还是代码中有问题，尽管跟踪跟踪问题似乎与 @ 987654322@输入但不知道怎么办

错误

Tasks: TOP => db:migrate

这是它指向的确切迁移：

class CreateProjects < ActiveRecord::Migration[5.0]
  def change
    create_table :projects do |t|
      t.string     :procect_name,   null: false
      t.numeric    :project_goal
      t.text       :prgoject_headline
      t.text       :prgoject_description 
      t.timestamps :expires_at

      t.timestamps
    end
  end
end

我想添加 ruby​​ 2.6.3 用于此项目，并且每当我运行迁移时都会显示此警告：

Answer 1

t.timestamps 不接受时间戳名称，仅接受哈希/关键字参数：

timestamps(options = {})

向表中添加时间戳（created_at 和 updated_at）列。

t.timestamps(null: false) Docs

如果您想添加expires_at，您需要使用正确的日期类型添加它（例如datetime：

class CreateProjects < ActiveRecord::Migration[5.0]
  def change
    create_table :projects do |t|
      # ...
      t.datetime :expires_at
    end
  end
end
