Question

在我的rails应用程序中，我有一个似乎无法正常工作的编辑表单。如果我通过任何链接进入编辑网站，一切都会好起来，但表单提交按钮将无法正常工作。如果我刷新窗口它工作正常。

Edit.html.erb

    <div class="alien-choice">
        <h2 class="player_name"><%= current_user.username %></h2>
        <p> Choose <span>0</span>/2 Power</p>

    <%= form_for [@gameround, @currentplayer] do |f| %>

        <% alleflares = @currentplayer.flares %>

        <% alleflares.each { |val| 
            printAlien = Alien.find_by_title(val)
        %>
        <div class="alien_wrap">
            <h3><%= printAlien.title  %> <span>[<%= printAlien.expansion.abbr   %>]</span></h3>

            <label for="<%= printAlien.title %>">
                <div class="alien" style="background-image: url(<%= printAlien.avatar.url %>)">
            </label>

            <%= f.check_box(:aliens, { :multiple => true, :id => printAlien.title, :class => 'choosealiens'}, printAlien.title, nil) %>

            </div>
        </div>


        <% } %>

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

<%= link_to 'Back', gameround_currentplayers_path %>

config.routes

Rails.application.routes.draw do


  resources :gamerounds do 
    resources :currentplayers
  end

Answer 1

我明白了。这只是因为提交按钮在主div之外。对不起，对不起！

Answer 2

您想要在config / routes.rb中创建路由，如下所示：

resources :current_players

Rails，编辑链接将重定向但更新按钮不会起作用
