Devise でユーザーを作成しようとしていますが、問題が発生しています。
home#land
def land
@resource = User.new
@devise_mapping = Devise.mappings[:user]
end
land.html.haml
= form_for @resource, :as => :user, :url => registration_path(:user), :remote => true do
= label_tag 'user[email]', raw("<h3>Stay Informed!</h3>")
= text_field_tag 'user[email]', nil, {:placeholder => "Your email", :required => true}
%input(type="submit" name="commit" value="Add")
user.rb
class User < ActiveRecord::Base
before_validation(:on => :create) do
self.password = "none"
self.password_confirmation = "none"
end
# Include default devise modules. Others available are:
# :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
# Setup accessible (or protected) attributes for your model
attr_accessible :email, :password, :password_confirmation, :remember_me
end
デフォルトの Devise::RegistrationsController が使用されています。
これは送信時に表示されます:

Completed 200 OK in 84ms (Views: 4.1ms | ActiveRecord: 1.0ms)
ただし、次の場合rails console

User Load (0.5ms) SELECT "users".* FROM "users"
=> #<ActiveRecord::Relation []>
そしてlocalhost:5000/users
完全に空です...
DB にユーザーがいないのに、User Exists と ROLLBACK が発生するのはなぜですか?
