Rails 4.1 ActionController::UnknownFormat 索引方法
Rails 4.1 ActionController::UnknownFormat in index method
我是菜鸟。在对其他问题进行详尽搜索后，我无法找到具有明确和正确答案的类似帖子。
首先，让我解释一下我的应用程序具有如下嵌套关联：
- 用户有一个客户
- 客户有很多帐户
- 用户有多个帐户通过客户
到目前为止，我已经使用 Devise 创建了一个用户，然后在控制台中手动将她分配给一个客户对象。在控制台也创建了对应的Account。 （嵌套创建的形式还没想好）
我现在想做的就是让用户在登录后进入 "landing" 页面，该页面显示她的帐户列表。听起来很简单，但我收到以下错误：
AccountsController 中的 ActionController::UnknownFormat#index
错误引用的代码...
@accounts = @user.accounts
respond_to do |format|
format.html # index.html.erb
format.json { render json: @account }
end
这是帐户控制器中的整个方法...
def index
@user = current_user
@accounts = @user.accounts
respond_to do |format|
format.html # index.html.erb
format.json { render json: @account }
end
end
我不明白是什么导致了错误。这是帐户索引的查看代码...
<h1>Listing accounts</h1>
<table id="indexTable" class="table table-striped">
<thead>
<tr>
<th colspan="5"></th>
</tr>
</thead>
<tbody>
<% if Account.exists? %>
<% for account in @accounts do %>
<tr>
<td><%= account.id %></td>
<td><%= %></td>
<td><%= link_to 'Show', account %></td>
<td><%= link_to 'Edit', edit_account_path(account) %></td>
<td><%= link_to 'Destroy', account, method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
<% else %>
<div class="jumbotron" style="text-align: center; border: 1px solid #DDD; border-radius: 8px;">
<h1>No accounts to display</h1>
</div>
<% end %>
</tbody>
</table>
<br>
<%= link_to 'New Account', new_account_path %>
我承认，观点本身可能有其自身的问题。但它甚至没有进入视野。错误指向controller，但会不会是routing的问题？这就是 routes.rb 的样子...
Rails.application.routes.draw do
devise_for :users, :controllers => { :registrations => "registrations" }
devise_scope :user do
post "/accounts/adminview" => "devise/sessions#new"
end
...
root 'home#index'
...
resources :accounts do
member do
get :adminview
end
end
resources :account_types, :accounts, :administrators, :customers, :transaction_types, :transactions, :users
...
end
似乎应该有一个简单的解决方案，但我是一个菜鸟。谁能帮我理解该怎么做？如何消除此错误并将我的用户带到她的帐户列表？
谢谢

我能看到的唯一错误是在你的控制器中，这个：
format.json { render json: @account }
应该是
format.json { render json: @accounts }
注意@accounts 上的额外 's'。但这可能不是全部。如果是，太好了！如果不能，你可以 post 你的完整帐户控制器和堆栈跟踪，以便我们可以解决这个问题吗？
对于 /accounts.ac045b73-8f9c-446f-9cc2-d86b01cea3b7，您的应用采用格式 ac045b73-8f9c-446f-9cc2-d86b01cea3b7，但您的控制器只知道如何处理 html 和 json。
你应该验证为什么 /users/sign_in 重定向到那个奇怪的 link

我能看到的唯一错误是在你的控制器中，这个：
format.json { render json: @account }
应该是
format.json { render json: @accounts }
注意@accounts 上的额外 's'。但这可能不是全部。如果是，太好了！如果不能，你可以 post 你的完整帐户控制器和堆栈跟踪，以便我们可以解决这个问题吗？
对于 /accounts.ac045b73-8f9c-446f-9cc2-d86b01cea3b7，您的应用采用格式 ac045b73-8f9c-446f-9cc2-d86b01cea3b7，但您的控制器只知道如何处理 html 和 json。
你应该验证为什么 /users/sign_in 重定向到那个奇怪的 link
