Rails 4缺少模板错误

Question

我正在使用带有 Devise 的 Rails 4 进行用户身份验证。我想在稍后阶段（在另一个页面上）收集用户的其他输入。

我收到一个模板错误，似乎因为我使用的是设计，所以与我的用户控制器存在一些冲突。设计控制器操作在应用程序控制器中（如果您也需要此代码，请使用 lmk）

当我提交表单时，这是我得到的模板错误：

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"

我的路线.rb

devise_for :users

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

在 app/controllers/users_controller.rb 中

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 app/views/users/edit.html.erb 中

<%= render 'form' %>

在 app/views/users/_form.html.erb 中

<%= 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

尝试将您的更新更改为：

  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

尝试在更新方法中添加一个respond_to或redirect_to块来指定用户在成功更新后被重定向到的路径。

Answer 3

这就是我通过复制设计视图并将内容添加到视图、模型等来实现的

在application_controller中添加了东西

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

结束

模型-用户

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

然后复制从我放在 app/views/devise 中的 Devise 的所有 te 视图 例如，这里是一个 app/views/devise/registrations/edit.html.erb。从记忆中用户名是我添加的一个字段以及currency_id。我还添加了用户头像（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>
<section>  
  <article class="single">
    <div class="form">
      <%= simple_form_for(resource, :as => resource_name, 
          :url => registration_path(resource_name),

        <div class="infogroup-header">Modify your account</div>        
        <%= f.error_notification %>
        <% if @user.errors.any? %>
          <%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:
          <% @user.errors.full_messages.each do |msg| %>
            <li><%= msg %></li>

        <% end %> <br />

              </tr>
              <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %>
