我试图从heroku进入我的应用程序的另一个页面，但我不能，因为它说“我们很抱歉，但出了点问题。”
这是我的heroku日志中的内容

现在我注意到，列'团队'不存在，但事实并非如此。这是我的页面：
<h1>Listing All Players</h1>
<div id="progressbar"><div class="progress-label">Loading...</div></div>
<a id="playerBtn"><button type="button" id="plyrBtn">Players</button></a>
<select id = "FilterTm">
<option>Select a Team...</option>
<% Abbrv.order("Team").each do |abbrv| %>
<option><%= abbrv.Team %></option>
<% end %>
</select>
<%#= link_to '<button type = "button">Players</button>'.html_safe, live_players_path(:Team => @tmf) %>
<br />
<br />
<input type="text" class="hiddenField" id="curTeam" style="border:none;" />
<select id = "ptable" size = 30>
<% @live_players.each do |live_player| %>
<option><%= live_player.Plyr %></option>
<% end %>
</select>
这是它试图获得的页面。现在这是我的路线文件：
TestfflApp::Application.routes.draw do
root "static_pages#home"
get "static_pages/Add_team"
resources :teamplayers
resources :fteams
resources :abbrvs
resources :live_players
get 'live_players', to: 'live_players#index' << Routed page
所以我在这里看了一下并完成了与此类似的问题的所有建议，所以我有什么问题？

答案 0 :(得分：0)
这是你的错误：
ActionView::Template::Error (PG::Error: ERROR: column "team" does not exist...
我的猜测是您通过迁移更新了数据库，但没有在Heroku上执行此操作。只需从控制台运行以下命令即可。
heroku run rake db:migrate
那应该可以解决你的错误。
