Prefix / Suffix feature

[mmarusyk]

This PR introduces an improvement for utilizing prefix and suffix options for attribute names in jsonb_accessor.

Why?

In some cases, it suffices to store certain information about orders in jsonb format when it's only needed for historical purposes or for generating invoices, etc.

Results

How it currently looks in the Order model:

class Order < ApplicationRecord
  jsonb_accessor :contact_details,
                 contact_details_email: [:string, { store_key: :email }],
                 contact_details_last_name: [:string, { store_key: :last_name }],
                 contact_details_first_name: [:string, { store_key: :first_name }],
                 contact_details_phone_number: [:string, { store_key: :phone_number }]

  jsonb_accessor :billing_details,
                 billing_details_email: [:string, { store_key: :email }],
                 billing_details_last_name: [:string, { store_key: :last_name }],
                 billing_details_first_name: [:string, { store_key: :first_name }],
                 billing_details_phone_number: [:string, { store_key: :phone_number }],
                 billing_details_full_address_line: [:string, { store_key: :full_address_line }]

  jsonb_accessor :shipping_details,
                 shipping_details_full_address_line: [:string, { store_key: :full_address_line }]
end

How it will look after implementing prefixes:

class Order < ApplicationRecord
  jsonb_accessor :contact_details,
                 email: [:string, { prefix: true }],
                 last_name: [:string, { prefix: true }],
                 first_name: [:string, { prefix: true }],
                 phone_number: [:string, { prefix: true }]

  jsonb_accessor :billing_details,
                 email: [:string, { prefix: true }],
                 last_name: [:string, { prefix: true }],
                 first_name: [:string, { prefix: true }],
                 phone_number: [:string, { prefix: true }],
                 full_address_line: [:string, { prefix: true }]

  jsonb_accessor :shipping_details,
                 full_address_line: [:string, { prefix: true }]
end

In rails console:

order.billing_details #=> {"email"=>"[email protected]", "last_name"=>"Mosciski", "first_name"=>"Chi", "phone_number"=>"475912955432", "full_address_line"=>"Suite 897 932 Nitzsche Shoal, Tammiborough, MI 90349-4217"}
order.billing_details_first_name #=> "Chi"
order.contact_details_first_name #=> "Marquita"

  id: 2,
  contact_details: {"email"=>"[email protected]", "last_name"=>"Marsk", "first_name"=>"Mike", "phone_number"=>"278587369859"},
  billing_details: {"email"=>"[email protected]", "last_name"=>"Mosciski", "first_name"=>"John", "phone_number"=>"475912955432", "full_address_line"=>"Suite 897 932 Nitzsche Shoal, Tammiborough, MI 90349-4217"},
  shipping_details: {"full_address_line"=>"38266 Durgan Motorway, Kulasmouth, NC 46602-3316"},
  contact_details_email: "[email protected]",
  contact_details_last_name: "Marsk",

  contact_details_phone_number: "278587369859",

  shipping_details_full_address_line: "38266 Durgan Motorway, Kulasmouth, NC 46602-3316">]
irb(main):014:0> Order.contact_details_where(last_name: "Random") #=> []

Also, it works fine with store key:

class Order < ApplicationRecord
  jsonb_accessor :contact_details,
                 email: [:string, { prefix: true, store_key: :e }], # Added store key
                 last_name: [:string, { prefix: true }],
                 first_name: [:string, { prefix: true }],
                 phone_number: [:string, { prefix: true }]

  jsonb_accessor :billing_details,
                 email: [:string, { prefix: true }],
                 last_name: [:string, { prefix: true }],
                 first_name: [:string, { prefix: true }],
                 phone_number: [:string, { prefix: true }],
                 full_address_line: [:string, { prefix: true }]

  jsonb_accessor :shipping_details,
                 full_address_line: [:string, { prefix: true }]
end

order.contact_details #=> {"e"=>"[email protected]", "last_name"=>"Kshlerin", "first_name"=>"Jessie", "phone_number"=>"567805903539"}
irb(main):021:0> order.contact_details_email="[email protected]" #=> "[email protected]"
order.contact_details_email #=> "[email protected]"
order.contact_details #=> {"e"=>"[email protected]", "last_name"=>"Kshlerin", "first_name"=>"Jessie", "phone_number"=>"567805903539"}
order.save #=> true
order.reload.contact_details #=> {"e"=>"[email protected]", "last_name"=>"Kshlerin", "first_name"=>"Jessie", "phone_number"=>"567805903539"}

For quering you can use name attribute without prefix/suffix:

Order.find(7).contact_details => {"e"=>"[email protected]"}
Order.contact_details_where(email: "[email protected]") # =>
[#<Order:0x00007f96bdd7a158
  id: 7,
  contact_details: {"e"=>"[email protected]"},
  billing_details: nil,
  shipping_details: nil,
  created_at: Sun, 07 Apr 2024 11:15:37.782726000 UTC +00:00,
  updated_at: Sun, 07 Apr 2024 11:15:37.782726000 UTC +00:00,
  contact_details_email: "[email protected]",
  contact_details_last_name: nil,
  contact_details_first_name: nil,
  contact_details_phone_number: nil,
  billing_details_email: nil,
  billing_details_last_name: nil,
  billing_details_first_name: nil,
  billing_details_phone_number: nil,
  billing_details_full_address_line: nil,
  shipping_details_full_address_line: nil>]

I'll be happy if we have this improvement in this gem. Thank you!

I'm not sure why CI is broken, don't think it's related to your change. I'll try to clean up the CI tomorrow 🤞

[ashkulz]

I still need to get some additional permissions from @darcygarrett so I can't merge #183 right now, hopefully I should get them soon 🤞

[ashkulz]

@mmarusyk I like the idea, but having to specify prefix: true for every field doesn't strike me as good. I'd rather have something like

class Order < ApplicationRecord
  jsonb_accessor :contact_details, prefix: true,
                 email: :string,
                 last_name: :string,
                 first_name: :string,
                 phone_number: :string

  jsonb_accessor :billing_details, prefix: true,
                 email: :string,
                 last_name: :string,
                 first_name: :string,
                 phone_number: :string,
                 full_address_line: :string

  jsonb_accessor :shipping_details,
                 full_address_line: :string
end

Since the signature for the macro is def jsonb_accessor(jsonb_attribute, field_types) I think we can add keyword arguments there (especially since we're targeting Ruby 3.2+), but I'm not sure how well it'll play with the implicit Hash being passed for the field_types. Or do you have any other suggestion how we'd be able to DRY it up further?

[mmarusyk]

@ashkulz Thanks for the feedback.

I agree that repeating prefix: true for every accessor isn't ideal. When I have time, I'll investigate ways to improve the macro, possibly by supporting keyword arguments.
