The `validates_includes` validation works with strings and numeric values
require 'sequel'
DB = Sequel.sqlite
DB.create_table(:users) do
primary_key :id
String :name, null: false
String :type
end
class User < Sequel::Model
plugin :validation_helpers
def validate
super
validates_presence [:name]
validates_includes %w(a b c), :type
end
end
irb> u = User.new(name: 'craig', type: 'a')
=> #<User @values={:name=>"craig",:type=>a}>
irb> u.valid?
=> true
However, if the validation is changed:
def validate
super
validates_presence [:name]
validates_includes %i(a b c), :type
end
the validations fail:
irb> u = User.new(name: 'craig', type: :c)
=> #<User @values={:name=>"craig",:type=>:c}>
irb> u.valid?
=> false
irb> u.errors
=> {:type=>["is not in range or set: [:a, :b, :c]"]}
Can symbols be used in this type of validation?
