Rails 4 Missing模板錯誤

Question

我正在使用Rails 4與Devise進行用戶身份驗證。我想在稍後階段（在另一頁上）收集用戶的額外輸入。

我得到一個模板錯誤，它似乎因爲我使用設計，與我的用戶控制器有一些衝突。設計控制器動作是在應用控制器（LMK如果需要此代碼太）當我提交表單

，這裏是模板的錯誤，我得到：

Missing template users/update, application/update with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in: * "C:/Users/amoosa/Desktop/mktdemo/app/views" * "C:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/gems/devise-3.2.4/app/views" 

我的routes.rb

devise_for :users 

resources :users, only: [:update, :edit] 

在應用程序/控制器/ users_controller.rb

class UsersController < ApplicationController 

    before_filter :load_user 

    def update 
    @user.update_attributes(user_params) 
    end 

    private 

    def load_user 
    @user = User.find(params[:id]) 
    end 

    def user_params 
    params.require(:user).permit(:color) 
    end 
end 

在應用程序/意見/使用者/ edit.html.erb

<%= render 'form' %> 

在應用程序/視圖/用戶/ _form.html.erb

<%= form_for @user, url: user_path, html: { method: :put } do |f| %> 
<div class="form-group"> 
    <%= f.label :what_is_your_favorite_color %> 
    <%= f.text_field :color, class:"form-control" %> 
</div> 

<div class="form-group"> 
    <%= f.submit "Submit", class:"btn btn-primary" %> 
</div> 

<% end %> 

Answer 1

嘗試改變你更新到：

def update 
    respond_to do |format| 
     if @user.update(user_params) 
     format.html { redirect_to @user, notice: 'User was successfully updated.' } 
     else 
     format.html { render action: 'edit' } 
     end 
    end 
    end 

Answer 2

嘗試增加在更新方法的respond_to代碼或redirect_to的塊來指定用戶被成功更新之後重定向到路徑。

Answer 3

這是我做到了通過複製andadding東西的看法，模型等

在application_controller的設計意見Iadded東西

class ApplicationController < ActionController::Base 
    protect_from_forgery 

    rescue_from CanCan::AccessDenied do |exception| 
    redirect_to root_url, :alert => exception.message 
    end 

    before_action :configure_devise_permitted_parameters, if: :devise_controller? 

    private 

    def configure_devise_permitted_parameters 
    registration_params = [:username, :email, :password, :password_confirmation, :role, :currency_id] 

    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :password, :remember_me) } 

    if params[:action] == 'update' 
     devise_parameter_sanitizer.for(:account_update) { 
     |u| u.permit(registration_params << :current_password) 
} 
    elsif params[:action] == 'create' 
     devise_parameter_sanitizer.for(:sign_up) { 
    |u| u.permit(registration_params) 
    } 
    end 
    end 

結束

模型 - 用戶

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    # add :confirmable for email confirmation 
    devise :database_authenticatable, :registerable, :confirmable, 
      :recoverable, :rememberable, :trackable, :validatable 

    has_many :posts, dependent: :destroy 
    has_many :comments, dependent: :destroy 
    has_many :evaluation_assumptions, dependent: :destroy 
    has_many :user_positions, dependent: :destroy 
    has_many :user_evaluation_results, through: :evaluation_assumptions 
    belongs_to :currency 

    validates :username, :role, :currency_id, presence: true 
    validates :username,:uniqueness => true 

    include RoleModel 

    roles_attribute :role 

roles :admin, :user, :guest 

end 

然後複製拷貝從設計的所有TE的觀點，我把在應用程序/視圖/設計 例如這裏是一個應用程序/視圖/設計/註冊/ edit.html.erb。從存儲器用戶名是我添加的字段以及currency_id。我還添加了用戶頭像（Gravatars）。

<% content_for :title, "Drill Investor - #{@current_user.username}" %> 
<% content_for :tab_group, "dashboard" %> 
<% content_for :tab_id, "dashboard" %> 
<div class="breadcrumbs"> 
    <%= link_to 'Users', edit_user_registration_path %> &raquo; 
    <%= link_to current_user.username %>

     <div class="infogroup-header">Modify your account</div>   
     <%= f.error_notification %> 
     <% if @user.errors.any? %>
