我正在尝试开发一个允许用户为其个人收藏创建、修改和添加类别的系统。用户可以查看个人收藏列表，但是要将项目添加或修改到他们的个人收藏中，必须创建一个帐户并且用户必须登录。
决定遵循来自 RailsCasts的https://github.com/ryanb/railscasts-episodes/tree/master/episode-250/revised/blog-after/app文件中的登录部分的源代码。
除了登录和注册表单外，其他一切都有效。
尝试加载页面时，我收到以下消息：
NoMethodError in UsersController#create
undefined method `password_digest=' for #<User:0x007fd8540db770>
Rails.root: /Users/laurens14/collections
Application Trace | Framework Trace | Full Trace
app/controllers/users_controller.rb:14:in `new'
app/controllers/users_controller.rb:14:in `create'
Request
Parameters:
{"utf8"=>"✓",
"authenticity_token"=>"rqrGlYSK5eSl9+P3WHkSgazwi2zyQyJUiB/G9G6UOU4=",
"user"=>{"email"=>"laurens14@icloud.com",
"password"=>"[FILTERED]",
"password_confirmation"=>"[FILTERED]"},
"commit"=>"Sign Up"}
这是所使用的控制器的源代码。
用户控制器：
class UsersController < ApplicationController
def new
@user = User.new
end
def create
@user = User.new(params[:user])
if @user.save
session[:user_id] = @user.id
redirect_to root_url, notice: "Thank you for signing up!"
else
render "new"
end
end
end
会话控制器：
class SessionsController < ApplicationController
def new
end
def create
user = User.find_by_email(params[:email])
if user && user.authenticate(params[:password])
session[:user_id] = user.id
redirect_to root_url, notice: "Logged in!"
else
flash.now.alert = "Email or password is invalid"
render "new"
end
end
def destroy
session[:user_id] = nil
redirect_to root_url, notice: "Logged out!"
end
end
应用程序控制器：
class ApplicationController < ActionController::Base
protect_from_forgery
private
def current_user
@current_user ||= User.find(session[:user_id]) if session[:user_id]
end
helper_method :current_user
def authorize
redirect_to login_url, alert: "Not authorized" if current_user.nil?
end
end
Collections_controller
class CollectionsController < ApplicationController
# GET /collections
# GET /collections.json
def index
@collections = Collection.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @collections }
end
end
def list
end
# GET /collections/1
# GET /collections/1.json
def show
@collection = Collection.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @collection }
end
end
# GET /collections/new
# GET /collections/new.json
def new
@collection = Collection.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @collection }
end
end
# GET /collections/1/edit
def edit
@collection = Collection.find(params[:id])
end
def search
@collections = Collection.find(:all, :conditions => ["title LIKE ?", "%#{params[:key]}%"])
end
# POST /collections
# POST /collections.json
def create
@collection = Collection.new(params[:collection])
respond_to do |format|
if @collection.save
format.html { redirect_to @collection, notice: 'Collection was successfully created.' }
format.json { render json: @collection, status: :created, location: @collection }
else
format.html { render action: "new" }
format.json { render json: @collection.errors, status: :unprocessable_entity }
end
end
end
# PUT /collections/1
# PUT /collections/1.json
def update
@collection = Collection.find(params[:id])
respond_to do |format|
if @collection.update_attributes(params[:collection])
format.html { redirect_to @collection, notice: 'Collection was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @collection.errors, status: :unprocessable_entity }
end
end
end
# DELETE /collections/1
# DELETE /collections/1.json
def destroy
@collection = Collection.find(params[:id])
@collection.destroy
respond_to do |format|
format.html { redirect_to collections_url }
format.json { head :no_content }
end
end
end
模型的源代码：
user.rb
class User < ActiveRecord::Base
has_secure_password
attr_accessible :email, :password, :password_confirmation
validates_uniqueness_of :email
end
collection.rb
class Collection < ActiveRecord::Base
attr_accessible :date, :description, :instructions, :title, :category_id
belongs_to :category
end
catergory.rb
class Category < ActiveRecord::Base
attr_accessible :name
has_many :Collection
end
这是 Rake 路由文件夹中的代码：
Collections::Application.routes.draw do
get 'signup', to: 'users#new', as: 'signup'
get 'login', to: 'sessions#new', as: 'login'
get 'logout', to: 'sessions#destroy', as: 'logout'
resources :users
resources :sessions
#resources :collections
resources :collections do
post 'search', :on => :collection
get 'list', :on => :collection
end
有什么建议么？
谢谢
