使rails控制台输出更漂亮

Question

rails控制台输出如下所示:

User.all
=> [#<User id: 1, name: "Michael Hartl", email: "mhartl@example.com",
created_at: "2011-12-05 00:57:46", updated_at: "2011-12-05 00:57:46">,
#<User id: 2, name: "A Nother", email: "another@example.org", created_at:
"2011-12-05 01:05:24", updated_at: "2011-12-05 01:05:24">]

我想知道是否有命令可以让它更容易阅读？例如,MongoDB控制台中有一个.pretty命令,它将输出格式化得更加友好.但不确定Rails中是否存在类似的东西.

Answer 1

更优雅的速记:

y User.all

Answer 2

如果你不想使用宝石,这里是低租金版本:

 puts User.all.to_yaml

Answer 3

我一直在用pp.pp代表"漂亮的印刷品".不需要宝石.

在rails控制台上尝试这样做:

pp User.all

如果您只是执行User.all,您将在记录显示中连续获取每个属性及其值,而不是捆绑它们.

这是文档:

https://ruby-doc.org/stdlib-2.1.0/libdoc/pp/rdoc/PP.html

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.

Answer 4

你也可以使用这个令人难以置信的宝石:

您可以尝试使用awesome_print gem:https: //github.com/michaeldv/awesome_print

安装完成后,您可以使用以下方法打印任何对象:

ap User.all

这里有几个选项

yaml 格式

y your_code

真棒_打印

gem install awesome_print

然后在 irb 或 pry

require 'awesome_print'
ap your_code

Answer 7

用 pry
