Making the rails console output a little more pretty
提问by Bohn
a rails console output looks like this:
rails 控制台输出如下所示：
User.all
=> [#<User id: 1, name: "Michael Hartl", email: "[email protected]",
created_at: "2011-12-05 00:57:46", updated_at: "2011-12-05 00:57:46">,
#<User id: 2, name: "A Nother", email: "[email protected]", created_at:
"2011-12-05 01:05:24", updated_at: "2011-12-05 01:05:24">]
I was wondering if there is command that can make it easier to read? for example there was a .prettycommand in MongoDB console that was formatting the output a little more eye friendly. But not sure if there is something similar in Rails or not.
我想知道是否有可以使其更易于阅读的命令？例如，MongoDB 控制台中有一个.pretty命令，它对输出的格式更加友好。但不确定 Rails 中是否有类似的东西。

I've been using pp. The pp stands for "pretty print." No Gem required.
我一直在用pp。pp 代表“漂亮的印刷品”。不需要宝石。
On rails console try doing this:
在 rails 控制台上尝试这样做：
pp User.all
You'll get each attributes and their value in the record display in a row instead a bundle of them if you simply do User.all.
如果您只执行 User.all，您将在记录显示中连续获得每个属性及其值，而不是一组它们。
Here's the documentation:
这是文档：
https://ruby-doc.org/stdlib-2.1.0/libdoc/pp/rdoc/PP.html
https://ruby-doc.org/stdlib-2.1.0/libdoc/pp/rdoc/PP.html
I am using Rails 5.1.3 and ruby 2.4.1p111 and it came already installed in my project. If this don't work, I imagine you have to do require 'pp'.
I hope this helps.
我正在使用 Rails 5.1.3 和 ruby 2.4.1p111，它已经安装在我的项目中。如果这不起作用，我想你必须这样做require 'pp'。我希望这有帮助。
