AuthLogic UserSessions控制器返回nil

Question

我已经成立了一个新的Rails应用程序和正在使用Authlogic进行身份验证。

我可以高兴地CRUD用户，但似乎与用户会话的问题。

错误消息：

undefined method `create' for nil:NilClass 
app/controllers/user_sessions_controller.rb:9:in `create' 

应用/模型/ user.rb

​​

应用程序/控制器/ user_sessions_controller.rb

class UserSession < Authlogic::Session::Base 
end 

应用/模型/ user_session.rb

class UserSessionsController < ApplicationController 

    def new 
    @user_sesssion = UserSession.new 
    end  

    def create 
    @user_sesssion = UserSession.new(params[:user_session]) 
    if @user_session.create 
     flash[:notice] = "Welcome back!" 
     redirect_to root_path 
    else 
     render :new 
    end 
    end 

    def destroy 
    @user_session = UserSession.find 
    @user_session.destroy 
    redirect_to root_path 
    end 
end 

应用/视图/ user_sessions

= simple_form_for @user_session do |f| 

    = f.error_notification 

    = f.input :username, :label => false, :placeholder => "User name", :required => true, :input_html => {:size => 15, :class => "signin_input"} 

    = f.input :password, :label => false, :placeholder => "Password", :required => true, :input_html => {:size => 15, :class => "signin_input"} 
    = f.button :submit, "Sign in", :class => "a small" 

分贝/ schema.rb

create_table "users", :force => true do |t| 
    t.string "username",   :null => false 
    t.string "email",    :null => false 
    t.string "crypted_password", :null => false 
    t.string "password_salt",  :null => false 
    t.string "persistence_token", :null => false 
    t.string "perishable_token" 
    t.datetime "created_at" 
    t.datetime "updated_at" 
    end 

    add_index "users", ["email"], :name => "index_users_on_email" 
    add_index "users", ["perishable_token"], :name => "index_users_on_perishable_token" 
    add_index "users", ["persistence_token"], :name => "index_users_on_persistence_token" 
    add_index "users", ["username"], :name => "index_users_on_username" 

的Gemfile

gem 'pg' 
gem 'heroku' 
gem 'authlogic' 
gem 'will_paginate' 
gem 'simple_form'

group :test do 
    gem 'factory_girl_rails' 
    gem 'capybara' 
    gem 'guard-rspec' 
end 

的config/routes.rb中

resource :users 
    resource :user_sessions 

    match 'signin', :to => "user_sessions#new" 
    match 'signout', :to => "user_sessions#destroy" 

    get "pages/home" 
    root :to => 'pages#home' 

经过一些玩弄它似乎是Authlogic ::会议的问题:: Base的

1.9.2-p290 :019 > session = UserSession.new(:username => "test", :password => "password") 
Authlogic::Session::Activation::NotActivatedError: You must activate the Authlogic::Session::Base.controller with a controller object before creating objects

    from script/rails:6:in `require' 
    from script/rails:6:in `<main>' 

我已经编辑application_controller.rb设法克服上述错误，但仍是同样的结果

before_filter :activate_authlogic 

    private 

    def activate_authlogic 
     Authlogic::Session::Base.controller = Authlogic::ControllerAdapters::RailsAdapter.new(self) 
    end

缺少什么我在这里？

你有一个错字，你拼写user_session一个额外秒。另外它是save你想调用会话，而不是`create。
