Hirb不在轨道控制台在所有的工作(Hirb doesn't work at all in

我就跟着教程hirb RDoc的 ，但不幸的是，我的rails控制台不工作。

我已经做了sudo gem install hirb

并添加hirb我的Gemfile：

gem 'hirb', '~>0.7.0'

然后，我推出了bundle install

而我得到这样的结果：

rails c
Loading development environment (Rails 3.2.11)
> require 'hirb'
=> false
> Hirb.enable
=> true
> Municipality.all
Municipality Load (0.8ms)  SELECT "municipalities".* FROM "municipalities" ORDER BY name asc
=> [#<Municipality id: 1, district_id: 6, name: "Ambalamanasy II", created_at: "2013-01-16 12:11:45", updated_at: "2013-01-16 12:11:45">,

# doesn't work

谁能帮助吗？

Answer 1:

If your using pry as your rails console... add this in your .pryrc file

require 'hirb'

Hirb.enable

old_print = Pry.config.print
Pry.config.print = proc do |output, value|
  Hirb::View.view_or_page_output(value) || old_print.call(output, value)
end

Answer 2:

Yoshdog的答案已经过时 - 它返回一个错误：

输出错误：＃NoMethodError：未定义的方法`寻呼机”的零：NilClass

您可以通过使用该解决此问题从文档更新的代码 ：

begin
  require 'hirb'
rescue LoadError
  # Missing goodies, bummer
end

if defined? Hirb
  # Slightly dirty hack to fully support in-session Hirb.disable/enable toggling
  Hirb::View.instance_eval do
    def enable_output_method
      @output_method = true
      @old_print = Pry.config.print
      Pry.config.print = proc do |*args|
        Hirb::View.view_or_page_output(args[1]) || @old_print.call(*args)
      end
    end

    def disable_output_method
      Pry.config.print = @old_print
      @output_method = nil
    end
  end

  Hirb.enable
end

这也将让您启用/禁用Hirb，这可能会派上用场。

Answer 3:

如果您在使用pry这对我的作品

$ pwd
/Users/me/path/rails-app
$ ls -la
-rw-r--r--   1 ryosuke  staff       554 12 26 17:50 .pryrc

和

begin
  require 'hirb'
rescue LoadError
  # Missing goodies, bummer
end

if defined? Hirb
  # Slightly dirty hack to fully support in-session Hirb.disable/enable toggling
  Hirb::View.instance_eval do
    def enable_output_method
      @output_method = true
      @old_print = Pry.config.print
      Pry.config.print = proc do |*args|
        Hirb::View.view_or_page_output(args[1]) || @old_print.call(*args)
      end
    end

    def disable_output_method
      Pry.config.print = @old_print
      @output_method = nil
    end
  end

  Hirb.enable
end
