这已被多次询问,但在尝试了我能找到的所有解决方案之后,我不再接近我自己的解决方案了。

我有一部分,_form - 这是相关部分:

<% @tournament.sub_tournaments.each do |sub| %>
  <%= f.fields_for :sub_tournaments, sub, :validate => false do |sub_form| %>
    ...
      <table>
        ...
        <tbody>
        <%= sub_form.fields_for :standings, :validate => false do |standings| %>
          <%= render 'tournaments/form_partials/standing_fields', f: standings, sub: sub %> #here's the problem
        <% end %>  
        </tbody>
      </table>
      ...
  <% end %>
<% end %>

在标记的行中,我试图将两个变量传递给给定的部分 - f: standingssub: sub。如果我只传递f: standings,页面加载正常,但是当我添加sub: sub时,我收到以下错误:

undefined local variable or method `sub'

引用_standing_fields partial:

中的以下标记行
<tr>
  <td><%= f.hidden_field :_destroy %><%= f.text_field :standing, :class => "standing", readonly: true, :type => "" %></td>
  <% if Game::TEAM_GAMES.include? sub.game.name %> #here's the problem
    <td><%= f.grouped_collection_select(:team_division_id, Team.order(:name).includes(:team_divisions), :team_divisions, :name, :id, :game_name, include_blank: true)%></td>
  <% else %>
    <td><%= f.grouped_collection_select(:player_id, Player.order(:name).includes(:player), :player, :name, :id, :game_name, include_blank: true)%></td>
  <% end %>
  <td><span class="remove">Remove</span></td>
</tr>

我无法想象出现了什么问题,我已经三次检查语法,拼写,逗号等,以及重新启动我的redis服务器和rails服务器作为一个解决方案建议。

您必须将变量放在本地键中:

<%= render 'tournaments/form_partials/standing_fields', locals: {f: standings, sub: sub} %>
