Awesome Print generally works perfectly for me in Rails.
But when doing ap Post.all
in the Rails console I only get the standard full line output.
Has it to do with the returned ActiveRecord_Relation
class or something else, because when an array is returned, like in ap Post.all.each {|p| p}
, Awesome Print does it's job.
Why not just convert it to array?
ap Post.all.to_a
or you can create a patch:
alias :old_ap :ap
def ap(object, option={})
if object.class == ActiveRecord::Relation::ActiveRecord_Relation_Post
old_ap object.to_a, option
else
old_ap object, option
end
end
You are right. Maybe it's an incompatible problem with Rails4 as the last commit on github is 6 months ago. Here is the problem:
awesome_print-1.2.0/lib/awesome_print/ext/active_record.rb@24
def cast_with_active_record(object, type)
cast = cast_without_active_record(object, type)
return cast if !defined?(::ActiveRecord)
if object.is_a?(::ActiveRecord::Base)
cast = :active_record_instance
elsif object.is_a?(Class) && object.ancestors.include?(::ActiveRecord::Base)
cast = :active_record_class
elsif type == :activerecord_relation #HERE the problem
cast = :array
end
cast
end
the method will set the cast to array when the type
is :activerecord_relation
while in awesome_print-1.2.0/lib/awesome_print/inspector.rb@151
def printable(object)
case object
when Array then :array
when Hash then :hash
when File then :file
when Dir then :dir
when Struct then :struct
else object.class.to_s.gsub(/:+/, "_").downcase.to_sym #HERE gets the type
end
end
But the class of Relation object in rails4 is like:
> Post.all.class
=> ActiveRecord::Relation::ActiveRecord_Relation_Post
So the condition in cast_with_active_record
gets a type "activerecord_relation_activerecord_relation_post" rather than "activerecord_relation". Then the condition is failed, and no cast done.
Here's a new patch that may work:
module AwesomePrint
class Inspector
alias_method :old_printable, :printable
private
def printable(object)
if object.class.to_s.downcase.include?("activerecord_relation")
return :activerecord_relation
end
old_printable(object)
end
end
end
