Question

Rails忽略了我的重定向。

用例：

用户导航到他的帐户并选择显示其订阅状态的选项
app列出了他当前的订阅以及取消它的选项
用户取消订阅
app更新订阅记录，将用户重定向回订阅操作

- ＆GT;但铁路忽略了最后一步......任何想法我做错了什么？

路线

map.resources :users, ..., :member => { ..., :subscriptions => :get, :subscribe => :post, :unsubscribe => :put}

控制器：

  def subscriptions
    @tradesman = User.find_by_id(params[:id])
    @subscription = @tradesman.current_subscription || Subscription.new
    @all_subscriptions = Subscription.find(:all)
  end

  def subscribe
    @tradesman = User.find_by_id(params[:id])    
    @subscription = current_user.subscriptions.build(params[:subscription])
    @subscription.update_attributes(:started_at => Time.zone.now)
    @subscription.save
    redirect_to :action => 'subscriptions', :id => @tradesman.id
  end

  def unsubscribe
    @tradesman = User.find_by_id(params[:id])
    @subscription = @tradesman.current_subscription
    @subscription.update_attributes(:ended_at => Time.zone.now)
    @subscription.save
    redirect_to :action => 'subscriptions', :id => @tradesman.id
  end

查看：

<div class = 'wrapper'>
  <%= render :partial => "my_account_leftbar" %>
  <% form_for @subscription, :url => subscribe_user_path(current_user) do |f| %>

        <% @all_subscriptions.each do |subscription| %>
      <div class="field">Start: <%= subscription.started_at %></div><br><br>
        <% end %>

        <% if @subscription.new_record? %>
      <div class="field">
            <%= f.check_box :subscription_type %>
            <div class="actions">
            <%= f.submit "Subscribe", :class => "button mr8" %>
          </div>
      </div>
        <% else -%>     
        <%= f.check_box :subscription_type, :value => @subscription.subscription_type, :disabled => true %>

            <% form_for @subscription, :url => unsubscribe_user_path(current_user) do |f| %>
          <div class="actions">
            <%= f.submit "Unsubscribe", :class => "button mr8" %>
          </div>
            <% end %>

        <% end %>

  <% end %>
</div>

Answer 1

使用redirect_to代替render（unsubscribe操作中的最后一次方法调用）。

Answer 2

在视图中找到了我在'subscribe'表单中嵌套'unsubscribe'表单的错误 - 什么都没有意义。

我重新安排了我的观点（将这两个表格分开，一个在'if'部分，另一个在'else'部分。现在工作正常：

<div class = 'wrapper'>
  <%= render :partial => "my_account_leftbar" %>
  <% @all_subscriptions.each do |subscription| %>
    <div class="field">Start: <%= subscription.started_at %></div><br><br>
  <% end %>

    <% if @subscription.new_record? %>
    <% form_for @subscription, :url => subscribe_user_path(current_user) do |f| %>
      <div class="field">
            <%= f.check_box :subscription_type %>
            <div class="actions">
            <%= f.submit "Subscribe", :class => "button mr8" %>
          </div>
      </div>
    <% end %>
    <% else -%>
    <% form_for @subscription, :url => unsubscribe_user_path(current_user) do |f| %>
    <%= f.check_box :subscription_type, :value => @subscription.subscription_type, :disabled => true %>
    <div class="actions">
      <%= f.submit "Unsubscribe", :class => "button mr8" %>
    </div>
    <% end %>
    <% end %>
</div>
