如何使嵌套表单在不同的控制器中工作

Question

我是编程和 Rails 的新手，我正在为我正在开发的应用程序进行注册流程。我有user 和profile 模型。作为注册过程的一部分，我混合了user 和profile 的字段，所以我使用的是嵌套表单。

我试图让嵌套表单在处理我的静态页面的控制器中工作，因为我想在主页上启动注册过程。

可以通过两种方式启动注册过程：直接从主页或在主页上跳过并在 /signup/skip 视图中启动。

我的 InfoController（其中存在带有表单的 home.html.erb 文件）：

def home
  if logged_in?
    redirect_to current_user.profile
  end
end

home.html.erb中的嵌套形式：

<%= form_for(:profile, :url => 'signup', :html => {:id => 'homepage'}) do |f| %>
  <p class="hometext">I'm&nbsp;</p>
  <div>
    <%= f.label :first_name, :placeholder => 'First name' %>
    <%= f.text_field :first_name, :size=> 8, :id => "profile[first_name]" %>
  </div>
  <div>
    <label for="profile[last_name]">Last name</label>
    <%= f.text_field :last_name, :size=> 8, :id => "profile[last_name]" %>
  </div>
  <%= f.fields_for :user do |f| %>
  <p class="hometext">.&nbsp;My&nbsp;email&nbsp;is&nbsp;
    <div>
      <label for="user[email]">Email</label>
      <%= f.text_field :email, :size=> 13, :id => "user[email]" %>
    </div>
  <% end %>
  <p class="hometext">.&nbsp;I want to&nbsp;</p>
  <div>
    <label for="user[stat]">put stat here</label>
    <%= f.text_field :stat, :size=> 13, :id => "user[stat]" %>
  </div>
  <p class="hometext">when I grow up.&nbsp;</p>
  <div id="button">
    <%= submit_tag 'Join', :class => 'button orange' %>
  </div>
<% end %>

个人资料模型：

class Profile < ActiveRecord::Base
  attr_accessible :first_name, :last_name ...
  belongs_to :user
  accepts_nested_attributes_for :user
end

用户模型：

class User < ActiveRecord::Base
  attr_accessor :password, :email
  accepts_nested_attributes_for :profile
  has_one :profile, :dependent => :destroy
end

由于某种原因，当我在表单中输入数据时，我被重定向到 /login，它在 Routes.rb 中为 Sessions#new。所以这里是 SessionsController：

class SessionsController < ApplicationController
  def create
    if user = User.authenticate(params[:email], params[:password])
      session[:user_id] = user.id
      redirect_to user.profile, :notice => "Logged in successfully"
    else
      flash.now[:alert] = "Invalid login/password. Try again!"
      render :action => 'new'
    end
  end

最后但并非最不重要的是 ProfilesController：

class ProfilesController < ApplicationController
  def new
    @profile = Profile.new
  end

  def create
    @profile = Profile.new(params[:profile])
    if @profile.save
      redirect_to profile_path, :notice => 'User successfully added.'
    else
      render :action => 'new'
    end
  end

更新：Routes 文件（至少相关部分）如下：

match '/login' => "sessions#new", :as => "login"
match '/signup', :to => 'profiles#new'
match 'skip/signup', :to => 'info#signupskip'
match 'skip/profiles/new', :to => 'profiles#newskip'
root :to => 'info#home'
resources :users
resources :profiles
resources :info

谁能帮我解决这个问题？任何有关如何使其工作并根据最佳实践进行操作的建议将不胜感激。

Answer 1

你能发布你的 routes.rb 吗？

另外，您是否为此查看过 Devise？看来您可能正在尝试重新发明轮子。

看看吧。。
