Simple Rails Form Objects

Simple Rails Form Object

class Forms::BaseForm
  include ActiveModel::Validations

  def initialize(attrs={})
    attrs ||= {}

    attrs.each do |k,v|
      self.send("#{k}=", v) ### Use send so that it checks that attr_accessor has already defined the method so its a valid attribute
    end
  end

  def to_key
    nil
  end

  def model_name
    sanitized_class_name = self.class.name.to_s.gsub("Forms::", '').gsub(/Form$/, '')
    ActiveModel::Name.new(self, self.class.superclass, sanitized_class_name)
  end

end

Usage Example

class Forms::ExampleForm < Forms::Base

  attr_accessor :app_id, :file

  validates :app_id, presence: {message: "Must select an App"}
  validates :file, presence: true
 
end
