load_resource得到一個零資源

在我的控制，我有：load_resource得到一個零資源

class UsersController < ApplicationController 

    load_and_authorize_resource 

    def create 

    respond_to do |format| 
     if @user.save 
     format.html { redirect_to @user, notice: 'User was successfully created.' } 
     format.json { render json: @user, status: :created, location: @user } 
     else 
     format.html { render action: "new" } 
     format.json { render json: @user.errors, status: :unprocessable_entity } 
     end 
    end 
    end 
end

，但我得到undefined method 'save' for nil:NilClass

Failures: 

1) UsersController if the user passes all the authorizations POST #create should create a new User with some parameters 
Failure/Error: post :create, :user => { :email => '[email protected]' } 
NoMethodError: 
    undefined method `save' for nil:NilClass 
# ./app/controllers/users_controller.rb:47:in `block in create' 
# ./app/controllers/users_controller.rb:46:in `create' 
# ./spec/controllers/users_controller_spec.rb:66:in `block (4 levels) in <top (required)>'

1 example, 1 failure

我期待load_resources填充@user = User.new(params[:user])

我看着黃燦燦的內部下整個流程和我發現在controller_resource.rb的時候我們達到了#build_resource我們有：

def build_resource 
    resource = resource_base.new(resource_params || {}) 
    assign_attributes(resource) 
end

但resource這裏是nil ...這是正常的嗎？我錯過了什麼？這與創建操作的問題有關？

編輯

這裏是我的ability.rb

class Ability 
    include CanCan::Ability 

    def initialize(user) 
    # Define abilities for the passed in user here. For example: 

    # check if the user is registered or a guest user (not logged in) 
    if user.present? 

     if user.any_role? :super_admin 
     can :manage, :all 
     end 

     if user.any_role? :admin 
     can :manage, [User, Institution, Project, Order] 
     end 

     if user.any_role? :user 
     can :show, Project 
     can [:add, :change], :cart 
     can [:create, :show], Order, :user_id => user.id 
     can :download, UrlConnector 
     end 

    end 
    end 
end

EDIT 2

在呼籲POST創建我有：

在RSpec的環境：

resource_base: User 
resource_class: User 
@params: {"user"=>{"email"=>"[email protected]"}, "controller"=>"users", "action"=>"create"}

在瀏覽器superadmin或admin，這是相同的：

resource_base: User 
resource_class: User 
@params: {"utf8"=>"✓", "authenticity_token"=>"95qQ4H/+CLU96jCIO6U/YtgIQ5zWxE7pg0BedVMPSGk=", "user"=>{"email"=>"[email protected]", "password"=>"264763", "password_confirmation"=>"264763", "ragionesociale"=>"fff", "partitaiva"=>"12345678901", "address"=>"via plutarco, 36", "city"=>"Manduria", "cap"=>"74024", "phone"=>"099979456", "role_ids"=>["3"]}, "commit"=>"Create User", "action"=>"create", "controller"=>"users"}

最後的寶石也可以粘貼'ability.rb'？ – AnkitG

@AnkitG肯定！剛剛添加。謝謝！ – enricostn

控制器的名稱是什麼？ –

試着將康康舞作爲Gemfile中
