Is there a way for the event methods to skip validations?

[terenceponce]

I want any state changes to exclusively go through the state machine and prevent other developers, including myself, to change the state directly via #create or #update. Here's an example:

class User < ApplicationRecord
  enum status: [:active, :inactive, :banned] do
    event :deactivate do
      transition :active => :inactive
    end

    event :ban do
      transition :active => :banned
    end
  end

  validates :status, inclusion: { in: %w(active) }, on: :create
  validates :status, absence: true, on: :update
end

As you can see, the validations make sure that the following code won't work:

User.create(state: "inactive")
User.create(state: "banned")
user.update(state: "inactive")
user.update(state: "banned")

Unfortunately, the event methods provided by stateful_enum won't work because it will have to go through the same validations. Is there a way for me to skip these validations when the state change comes from stateful_enum?

Interesting idea. I’ve never thought of that, but suggestions with implementations are welcome!

Sorry, just closed the issue by accident, but I’ll leave this opened until someone actually implements this.

Not exactly what you're trying to achive @terenceponce, but I prevent records from transitioning to an invalid state through #create or #update methods in this PR #49
