Do not raise ArgumentError when assigning a blank value about array_enum HOT 4 CLOSED

Hey @koki-sato what would be a use-case for such behavior?

Is it just for instantiation and before persisting?

from array_enum.

Yes!

I expect the following behavior.

class User < ActiveRecord::Base
  extend ArrayEnum

  array_enum favourite_colors: {"red" => 1, "blue" => 2, "green" => 3}

  validates :favourite_colors, subset: { in: favourite_colors.keys }
end

user = User.new(favourite_colors: [""]) # Do not raise ArgumentError!
user.save # => false
user.errors.messages[:favourite_colors] # Display inclusion validation error message

For example, when the following data is HTTP POSTed in an HTML Form

user[favourite_colors][]: 

Rails Parameters look like this:

Parameters: { "user" => { "favourite_colors" => [""] } }

from array_enum.

@koki-sato I'll have a look into it, tho can't give a timeline right now. But if you already have some idea on how it'll work, feel free to create a PR and I'll review it.
