Default Value Using Proc

[jiunjiun]

I've been developing using the default value with proc in Kredis and encountered an issue.

However, I'm not sure if there's a misunderstanding in my use of the design.

app/models/user.rb
class User < ApplicationRecord
  kredis_string :full_name, default: ->(u) { "#{u.first_name} #{u.last_name}" }
end

user1 = User.create(first_name: 'John', last_name: 'Doe')
user2 = User.create(first_name: 'Tom', last_name: 'Smith')

I expected it to work like this:

user1.full_name # => 'John Doe'
user2.full_name # => 'Tom Smith'

But what actually happens is:

user1.full_name # => 'John Doe'
user2.full_name # => 'John Doe'

The default proc for the user seems to retrieve the data of the first user record.

Upon further investigation, it seems related to this segment of the code:

kredis/lib/kredis/attributes.rb

Line 132 in 4fbb2f5

when Proc then Proc.new { default.call(self) }

May I ask if this is considered an issue?

I am also facing the same issue, so instead of having a default proc i need to manually add the first value in cache if it doesn't exists using a redis transaction

just want to know if this is intended behavior or a bug
