Public Instance Methods

debug(object) click to toggle source

Returns a YAML representation of object wrapped with 

 and
. If the object cannot be converted to YAML using to_yaml, inspect will be called instead. Useful for inspecting an object at the time of rendering.

Example

  @user = User.new({ :username => 'testing', :password => 'xyz', :age => 42}) %>
  debug(@user)
  # =>
  <pre class='debug_dump'>--- !ruby/object:User
  attributes:
  &nbsp; updated_at:
  &nbsp; username: testing

  &nbsp; age: 42
  &nbsp; password: xyz
  &nbsp; created_at:
  attributes_cache: {}

  new_record: true
  </pre>
    # File lib/action_view/helpers/debug_helper.rb, line 29
29:       def debug(object)
30:         begin
31:           Marshal::dump(object)
32:           "<pre class='debug_dump'>#{h(object.to_yaml).gsub("  ", "&nbsp; ")}</pre>".html_safe
33:         rescue Exception => e  # errors from Marshal or YAML
34:           # Object couldn't be dumped, perhaps because of singleton methods -- this is the fallback
35:           "<code class='debug_dump'>#{h(object.inspect)}</code>".html_safe
36:         end
37:       end
