summary ActiveHash::Relation returned by ActiveHash#where should be reported like as an array of ActiveHash items selected by where method, in Rails Console. Because ActiveRecord::Relation returned by ActiveRecord#where is reported like as an array of ActiveRecord instances selected by where method, in Rails Console.

environment

• Ruby: ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [aarch64-linux]
• Rails: 7.0.4
• active_hash 3.1.1

Steps to reproduce

1. Install active_hash gem to your rails app.
2. Start rails cosole.
3. Execute this code;

   class Layout < ActiveHash::Base
   self.data = [
   { id: 1, name: '1R' },
   { id: 2, name: '1K' },
   { id: 3, name: '1DK' },
   { id: 4, name: '1LDK' },
   { id: 5, name: '2K' },
   { id: 6, name: '2DK' },
   { id: 7, name: '2LDK' },
   { id: 8, name: '3K' },
   { id: 9,  name: '3DK' },
   { id: 10, name: '3LDK' },
   { id: 11, name: '4K' },
   { id: 12, name: '4DK' },
   { id: 13, name: '4LDK以上' },
   ]
   end
   Layout.where(id:[1..3])

actual result

#<ActiveHash::Relation:0x0000ffffb4b5b008
 @all_records=
  [#<Layout:0x0000ffffb4406c58 @attributes={:id=>1, :name=>"1R"}>,
   #<Layout:0x0000ffffb4406848 @attributes={:id=>2, :name=>"1K"}>,
   #<Layout:0x0000ffffb4406618 @attributes={:id=>3, :name=>"1DK"}>,
   #<Layout:0x0000ffffb44063e8 @attributes={:id=>4, :name=>"1LDK"}>,
   #<Layout:0x0000ffffb44061b8 @attributes={:id=>5, :name=>"2K"}>,
   #<Layout:0x0000ffffb4405f88 @attributes={:id=>6, :name=>"2DK"}>,
   #<Layout:0x0000ffffb4405d58 @attributes={:id=>7, :name=>"2LDK"}>,
   #<Layout:0x0000ffffb4405b28 @attributes={:id=>8, :name=>"3K"}>,
   #<Layout:0x0000ffffb44058f8 @attributes={:id=>9, :name=>"3DK"}>,
   #<Layout:0x0000ffffb44056c8 @attributes={:id=>10, :name=>"3LDK"}>,
   #<Layout:0x0000ffffb4405498 @attributes={:id=>11, :name=>"4K"}>,
   #<Layout:0x0000ffffb4405268 @attributes={:id=>12, :name=>"4DK"}>,
   #<Layout:0x0000ffffb4405010 @attributes={:id=>13, :name=>"4LDK以上"}>],
 @klass=Layout,
 @query_hash={:id=>[1..3]},
 @records_dirty=true>

expected result

[
#<Layout:0x0000ffffb4406c58 @attributes={:id=>1, :name=>"1R"}>, 
#<Layout:0x0000ffffb4406848 @attributes={:id=>2, :name=>"1K"},
#<Layout:0x0000ffffb4406618 @attributes={:id=>3, :name=>"1DK"}>
]

additional information

Now I'm trying to fix this problem. I'm researching which is the code should be modified: activehash, rails console, or irb itself.

Model.limit(3).class
=> Vm::ActiveRecord_Relation

byebug ; pp Model.limit(3)
# byebug ; Model.limit(3)

# s
# up
# s
# up

[598, 607] in /Users/kbrock/.rubies/ruby-3.0.6/lib/ruby/3.0.0/pp.rb
   598:
   599:   # prints arguments in pretty form.
   600:   #
   601:   # pp returns argument(s).
   602:   def pp(*objs)
=> 603:     objs.each {|obj|
   604:       PP.pp(obj)
   605:     }
   606:     objs.size <= 1 ? objs.first : objs
   607:   end
(byebug) objs.class
Array

That has me confused. Not sure why this would be an array and not a relation class Sorry I don't have the bandwidth to go further.

[flavorjones]

What's going on here is that IRB's REPL loop runs pp to print the previous line's value.

We can customize the pp output for Active Hash associations by implementing a #pretty_print method as documented in PP Output Customization.

I'll give it a try!
