Calling `#name` unexpectedly …

[antonysastre]

Complete Description of Issue

My form is calling #name on it's model without (what I can see) reason?

class UserForm < Reform::Form
  model :user

  property :email
  property :first_name
  property :last_name
  property :password
  property :password_confirmation

  validates_uniqueness_of :email

  validates :first_name, :last_name, :email, presence: true
  validates :email, format: Devise.email_regexp
  validates :password, presence: true, if: -> { model.new_record? }
  validates :password, confirmation: true, length: Devise.password_length, allow_blank: true
end

def new
  def new
    @form = UserForm.new(User.new)
  end
end

class User < ActiveRecord::Base
  devise :database_authenticatable, :recoverable, :rememberable, :trackable
end

# Created by migration:
  create_table "users", id: :serial, force: :cascade do |t|
    t.string "email", default: "", null: false
    t.string "encrypted_password", default: "", null: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.string "first_name"
    t.string "last_name"
    t.index ["email"], name: "index_users_on_email", unique: true
    t.index ["reset_password_token"], name: "index_users_on_reset_password_token", unique: true
  end

Expected behavior

A form view rendering - which works if I remove the Reform wrapper and just return the new user. I.e. @form = User.new works.

Actual behavior

I get a NoMethodError in the controller action (Not the view, no call to :name is made neither in the view nor in the model.

NoMethodError at /admin/users/new undefined method `name' for #<User:0x00007f9224de0d38>
