轨道4嵌套表格色器件登录我出去更新(Rails 4 Nested form with devise

我有与装置和后没有设计出子模型建立父模型嵌套形式。 我工作具有用户模型领域和嵌套在这些专家的模型字段编辑表单上。 更新/保存的作品，但我注销了，给我一个错误说“您需要登录或继续之前注册”当我再次登录我看到领域都得到了正确更新。 我想它不会签我，并告诉我更新的编辑页面时提交表单。

用户模式 ​​- 用色器件内置。

class User < ActiveRecord::Base
// some stuff 
has_one :expert
accepts_nested_attributes_for :expert, :update_only => true
// more stuff

专家模式 - 建立无色器件。

class Expert < ActiveRecord::Base  
belongs_to :user

用户控制器：

before_action :set_user, only: [:show, :edit, :update, :destroy]
before_filter :authenticate_user!, :only => [:show, :edit]

def edit
  @user = User.friendly.find(params[:id])
  @title = "Edit Profile"
end

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

  private
# Use callbacks to share common setup or constraints between actions.
def set_user
  @user = User.friendly.find(params[:id])
end

# Never trust parameters from the scary internet, only allow the white list through.
def user_params
  params.require(:user).permit(:id, :name, :email, :phone, :password, :role, :expert_attributes => [:id, :Location])
end

end

专家控制器：

def edit
  @expert = Expert.find(params[:id])
  @title = "Edit Expert Profile"
end

编辑用户视图形式局部：

<%= form_for(@user) do |f| %>
  <% if @user.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>

      <ul>
      <% @user.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">
    <%= f.label :Name %><br>
    <%= f.text_field :name, :class => "form-control" %>
  </div>


  <div class="field">
    <%= f.label :Email %><br>
    <%= f.text_field :email, :class => "form-control" %>
  </div>

  <div class="field">
    <%= f.label :Phone %><br>
    <%= f.text_field :phone, :class => "form-control" %>
  </div>


  <div class="field">
    <%= f.label :Password %><br>
    <%= f.text_field :password, :class => "form-control" %>
  </div>

  <div class="field">
    <%= f.fields_for :expert do |e| %>
      <%= e.label :Location %><br />
      <%= e.text_field :Location %>
    <% end %>
  </div>

  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

Answer 1:

在你的UsersController ，你应该增加:update到authenticate_user! 过滤：

before_filter :authenticate_user!, :only => [:show, :edit, :update]
