“nil"不是返回有效部分路径的 ActiveModel 兼容对象 [英] 'nil' is not an ActiveModel-compatible object that returns a valid partial path

问题描述

第一个问题，请温柔:)

我无法为属于具有 has_many 关联的用户模型的客户端模型创建索引视图.

错误信息:

'nil' 不是返回有效部分路径的 ActiveModel 兼容对象.

特别是错误是指第 11 行的部分错误:

/views/clients/index.html

<% provide(:title, current_user.name) %><div class="row"><aside class="span4"><部分><h1>您的客户</h1></节></一边><div class="span8"><% if current_user.clients.any?％＞<ol class="clients"><%= 渲染@clients %></ol><%= will_paginate %><%结束%>

/clients/_client.html.erb

<span class="client-name"><%= client.name %></span><span class="client-info">额外的客户信息即将到来.</span>

客户端控制器:

class ClientsController <应用控制器归属地:用户定义索引@clients = current_user.clients.paginate(page: params[:page])结尾

用户控制器，如果有帮助...

class UsersController <应用控制器before_filter :authenticate_user!高清秀如果 current_user.admin?@user = User.find(params[:id])别的@user = current_user结尾结尾定义索引如果 current_user.admin?@users = User.paginate(page: params[:page])别的重定向到 root_path结尾结尾销毁User.find(params[:id]).destroyflash[:success] = "用户已销毁."重定向到用户路径结尾结尾

你可能会说我是 Rails 的新手，但我已经搜索过以确保这还没有被覆盖.

解决方案

我在客户端控制器和模型中声明了belongs_to，而不仅仅是模型.而且两天都没注意到.

First question, please be gentle :)

I am having trouble creating an index view for a client model that belongs_to the user model with a has_many association.

The error message:

'nil' is not an ActiveModel-compatible object that returns a valid partial path.

Specifically the error refers to the partial on line #11:

/views/clients/index.html

<% provide(:title, current_user.name) %>
<div class="row">
  <aside class="span4">
    <section>
      <h1>Your clients</h1>
    </section>
  </aside>
  <div class="span8">
    <% if current_user.clients.any? %>
      <ol class="clients">
        <%= render @clients %>
      </ol>
      <%= will_paginate %>
    <% end %>
  </div>
</div>

/clients/_client.html.erb

<li>
  <span class="client-name"><%= client.name %></span>
  <span class="client-info">
    Extra client info to come.
  </span>
</li>

Clients controller:

class ClientsController < ApplicationController
  belongs_to :user

  def index
    @clients = current_user.clients.paginate(page: params[:page])
  end

EDIT:

Users controller if it helps...

class UsersController < ApplicationController
  before_filter :authenticate_user!

  def show
    if current_user.admin?
        @user = User.find(params[:id])
    else
        @user = current_user
    end
  end

  def index
    if current_user.admin?
        @users = User.paginate(page: params[:page])
    else
        redirect_to root_path
    end
  end

  def destroy
        User.find(params[:id]).destroy
        flash[:success] = "User destroyed."
        redirect_to users_path
    end
  end

As you can probably tell I am new to rails, but have searched to ensure this hasn't been covered already.

解决方案

I declared belongs_to in the clients controller and the model instead of just the model. And didn't notice for two days.
