Rails 4缺少模板错误

Question

I'm using Rails 4 with Devise for user authentication. I'd like to collect additional inputs from users at a later stage (on another page).

I'm getting a template error and it seems like since I'm using devise, there is some conflict with my user controller. Devise controller actions are in the application controller (lmk if you need this code too)

When I submit the form, here is the template error I get:

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"

my routes.rb

devise_for :users

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

In app/controllers/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

In app/views/users/edit.html.erb

<%= render 'form' %>

In app/views/users/_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

Try to change you update to:

  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update方法中添加response_to或redirect_to块，以指定成功更新后用户重定向到的路径。

Answer 3

this is how I did it by copying the devise views andadding stuff to views, model etc

In the application_controller Iadded stuff

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

end

Model -user

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

Then copied copied all te views from Devise which I put in app/views/devise for example here is the one app/views/devise/registrations/edit.html.erb. From memmory username was a field I added as well as currency_id. I also added user avatars (Gravatars).
