Question

在研究了SO之后，我发现我希望注册过程如下：

用户填写表格
用户点击“加入”
创建/登录用户并重定向以填写个人资料
点击按钮
用户定向到个人资料

如果我要在rails console中创建用户和用户的个人资料，它将如下所示：

user = User.new
user.email = ""
user.password = ""
user.profile = Profile.new
user.profile.info = ""
user.profile.save
user.save

问题：我在主页上使用嵌套模型表单来创建用户并添加该用户的个人资料名/姓。现在发生的事情是：用户单击“加入”，将它们重定向到/ users，然后重定向到/ signup。那就是我被困住的地方。它给了我以下错误：

Action Controller: Exception caught
NoMethodError in ProfilesController#new
undefined method `profile=' for nil:NilClass
app/controllers/profiles_controller.rb:5:in `new'

我希望/注册成为填写个人资料的表单，但它不起作用。

我的代码如下......

用户＃new.html.erb（首页表单）：

<%= form_for(@user, :html => {:multipart => true, :id => 'homesign'}) do |f| %>
  <%= f.hidden_field :id %>
  <% if @user.errors.any? %>
  <% end %>
  <div>
    <%= f.label :email %>
    <%= f.text_field :email, :size => 38 %>
  </div>
  ...
  <%= f.fields_for :profile do |profile| %>
    <%= profile.label :first_name %>
    <%= profile.text_field :first_name, :size => 18 %>
    ...
  <% end %>
<% end %>

个人资料＃new.html.erb（注册表单）：

<%= form_for @profile, :html => { :multipart => true } do |f| %>
  <table id="signupTable">
    <tbody>
      <tr>
        <td class="label"><%= f.label :gender, "Gender:" %></td>
        <td>
        <fieldset>
          <%= select(:gender, :gender_type, [['Female', 1], ['Male', 2], ['Rather not say', 3]], :class => 'optionText') %>
        </fieldset>
        </td>
      </tr>
      <tr>
        <td class="label"><%= f.label :birthday, "Birthday:" %></td>
        <td>
        <fieldset>
          <%= select_month(14, :prompt => 'Month', :field_name => 'Month', :id => 'Date.mon') %>
          <%= select_day(32, :prompt => 'Day') %>
          <%= select_year(0, {:prompt => "Year", :start_year => DateTime.now.year, :end_year => DateTime.now.year - 115}, {:field_name => 'Year', :id => 'Date.year'}) %>
        </fieldset>
<% end %>

User.rb：

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

  validates :email, :uniqueness => true, 
                :length => { :within => 5..50 }, 
                :format => { :with => /^[^@][\w.-]+@[\w.-]+[.][a-z]{2,4}$/i }
  validates :password, :confirmation => true,
                   :length => { :within => 4..20 },
                   :presence => true,
                   :if => :password_required?
end

Profile.rb：

class Profile < ActiveRecord::Base
  belongs_to :user
  accepts_nested_attributes_for :user
end

UsersController：

class UsersController < ApplicationController
  before_filter :authenticate, :only => [:edit, :update]

  def new
    @user = User.new
    @user.profile = Profile.new
    if logged_in?
      redirect_to current_user.profile
    end
  end

  def index
    @user = User.all
  end

  def create
    @user = User.new(params[:user])
    if @user.save
      session[:user_id] = user.id
      redirect_to new_user_profile_path(:user_id => @user), :notice => 'User successfully added.'
    else
      render :action => 'new'
    end
  end
end

ProfilesController：

class ProfilesController < ApplicationController
  before_filter :authenticate, :only => [:edit, :update]

  def new
    @user.profile = Profile.new
  end

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

  def index
    @profile = current_user.profile
  end
end

SessionsController（仅限创建）：

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
end

routes.rb中：

match "/signup" => "profiles#new", :as => "signup"
post "/profiles/new" => "profiles#create"
match "skip/signup", :to => "info#signupskip"
match "skip/profiles/new", :to => "profiles#newskip"
get "/profiles/:id" => "profiles#show", :as => "profile"
get "profiles/new"
root :to => "users#new"
