# Provides a set of methods for making it easier to debug Rails objects.

module DebugHelper
|
|
# Returns a YAML representation of +object+ wrapped with <pre> and </pre>.
|
|
# 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:
|
|
# updated_at:
|
|
# username: testing
|
|
#
|
|
# age: 42
|
|
# password: xyz
|
|
# created_at:
|
|
# attributes_cache: {}
|
|
#
|
|
# new_record: true
|
|
# </pre>
