Constructor Details

#initialize(atts = {}, options = {}) ⇒ Form

Initialize with a hash of attributes and values. If extra attributes are sent, a NoMethodError exception will be raised.

Examples:


class EditPost < Scrivener
  attr_accessor :title
  attr_accessor :body

  def validate
    assert_present :title
    assert_present :body
  end
end

edit = EditPost.new(title: "Software Tools")

edit.valid? #=> false

edit.errors[:title] #=> []
edit.errors[:body]  #=> [:not_present]

edit.body = "Recommended reading..."

edit.valid? #=> true

# Now it's safe to initialize the model.
post = Post.new(edit.attributes)
post.save
