Default value based on another value?

[Mike Coutermarsh]

Hey,

Had this idea, not sure if currently possible.

Would be nice if we could set a default to be based on another existing value.

Use Case:

• I want to add a new "notification setting"
• Can base this settings default on another already existing setting.
• This way, the setting is "smart" and auto sets itself based on what user has done in the past.

Such as:

store_attributes :email_settings do
  subscribed_to_email Boolean, default: true
  subscribe_to_comment_notification_email Boolean, default: subscribed_to_email
end

Is it possible today?

If not - any interest in having this ability in the gem? (I can work on it)

@mscoutermarsh this might already work, because Virtus ;)

Can you try:

store_attributes :email_settings do
  subscribed_to_email Boolean, default: true
  subscribe_to_comment_notification_email Boolean, lazy: true, default: :subscribed_to_email
end
