Ruby on rails RubyonRails：显示存储在MyUsers表（终端）中的数据

我找了很多，但找不到答案

如何查看/检查/显示存储在用户表中的数据

我已经看到有一个软件可以实现这一点，但有没有一个好的终端方式来实现这一点

我已经做到了：

rails c
User.all

返回

(0.4ms)  SELECT sqlite_version(*)   User Load (0.1ms)  SELECT "users".* FROM "users" LIMIT ?  [["LIMIT", 11]]
=> #<ActiveRecord::Relation [#<User >]>

（0.4ms）选择sqlite_版本（*）用户加载（0.1ms）选择“用户”。*从“用户”限制？[“限制”，11]]
=> #

我猜这里只有一行，但是我如何查看数据（列和行）

---

谢谢

使用-

rails c在终端中尝试此功能：

User.pluck().sort().insert(0, ContactUs.column_names).map {|s| s.join "\t|\t" }

如果您在终端中执行rails db

，它将提供对sqlite>

您可以启动db查询：sqlite>

select*from Users
这应该返回表中存储的任何内容，例如

1|2020-02-14 13:36:12.604676|2020-02-14 13:36:12.604676|user1|password1

2|2020-02-17 10:27:10.374015|2020-02-17 10:27:10.374015|user2|password2

在rails c中，您可以执行以下操作：

pp User.pluck() 

应该返回类似于

  (0.2ms)  SELECT "users".* FROM "users"

希望有帮助。
您可以尝试“p User.all”或“User.all.each{u | p u}”
