未定義的方法regular_user_path（誓言面向對象的方法）

Question

我已經實現了一個誓言面向對象的方法來使用我的rails應用程序tutorial。我還將我的用戶表單分成了一個編輯&帳戶表單。

用戶編輯表單

-Name 
-Username 
-AboutMe 

用戶帳戶表格

-Email 
-Password 
-Password Confirmation 

似乎一切都還好的工作，直到我試圖編輯一個普通用戶的帳戶或配置文件。出於某種原因，我不斷收到此錯誤。

undefined method `regular_user_path' for #<#<Class:0x007fc1952f6da0>:0x007fc18bf350a8> 

我不知道爲什麼會發生這種情況。以下是我的代碼如下。

模型

class User < ActiveRecord::Base 
    attr_accessible :name, :bio, :avatar, :username 
end 

class RegularUser < User 

    has_secure_password 

    VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i 
    VALID_UNAME_REGEX = /^[a-z](\w*[a-z0-9])*$/i 

    validates :name, length: { maximum: 50 } 

    validates :username, :presence => true, 
        :length  => { :maximum => 15 }, 
        :format  => { :with => VALID_UNAME_REGEX }, 
        :uniqueness => { :case_sensitive => false } 

    validates :bio, length: { maximum: 50 } 

end 

控制器

class UsersController < ApplicationController 

    before_filter :signed_in_user, only: [:index, :profile, :update, :destroy, :following, :followers, :account] 
    before_filter :correct_user, only: [:edit, :update, :account] 
    before_filter :admin_user,  only: [:destroy] 

    def edit 
    @user = User.find_by_username(params[:id]) 
    end 

    def account 
    @title = "Account" 
    @user = User.find_by_username(params[:id]) 
    end 

    def update 
    @user = RegularUser.find(current_user.id)  ###I think this is causing it 
    if @user.update_attributes(params[:user]) 
     flash[:success] = "Profile updated" 
     sign_in @user 
     redirect_to root_url 
    else 
     if URI(request.referer).path == edit_user_path ###redirects to appropriate page 
     render 'edit' 
     else 
     render 'account' 
     end 
    end 
    end 

def destroy 
    User.find_by_username(params[:id]).destroy 
    flash[:success] = "User destroyed." 
    redirect_to users_url 
end 

private 

    def signed_in_user 
    unless signed_in? 
     store_location 
     redirect_to (root_path), notice: "Please sign in." 
    end 
    end 

    def correct_user 
    @user = User.find_by_username(params[:id]) 
    redirect_to(root_path) unless current_user?(@user) 
    end 

    def admin_user 
    redirect_to(root_path) unless current_user.admin? 
    end 

end

Answer 1

在你update動做的建議如下：

def update 
    @user = RegularUser.find(current_user.id)  
    if @user.update_attributes(params[:user]) 
     flash[:success] = "Profile updated" 
     sign_in @user 
     redirect_to root_url 
    else 
     error_messages = @user.errors.messages  ### Capture the error messages 
     @user = User.find_by_username(params[:id]) ### Add this line 
     @user.errors.messages.merge!(error_messages) ### Set the error messages hash 
     if URI(request.referer).path == edit_user_path 
     render 'edit' 
     else 
     render 'account' 
     end 
    end 
    end 

當您更新失敗，您需要將@user重置爲User實例，否則當你render編輯查看它將收到RegularUser實例，而不是User實例，而您的表單預計User實例。

嘗試增加resources :regular_users到您的routes.rb文件
