Heroku-Pipeline - identischer Code für Staging & Produktion, aber Produktionspausen

Question

Ich bin neu bei Rails (und Heroku) und habe eine Pipeline für die Bereitstellung verwendet. Ich nehme an, dass beide Umgebungen identisch sind - ich verwende einen für die Bereitstellung und einen für die Bereitstellung.

Das Staging funktioniert einwandfrei, aber wenn Code für die Produktion freigegeben wird, bricht es. Diese Datei scheint das Problem zu sein, aber ich kann nicht sehen warum - irgendeine Idee?

<div class="row invite-friends" data-page-id-invite-friend=''> 
 
    <div class="col-lg-3"> 
 
    <%= render 'shared/user_info'%> 
 
    </div> 
 
    <div class="col-lg-6 well"> 
 
    <h3>Plans</h3> 
 
    <p>Choose a plan to help you reach your goals. All plans deliver structured content from our team of experienced trainers to your feed every day.</p> 
 
    <hr /> 
 
    
 

 

 
<div id="accordion" role="tablist" aria-multiselectable="true"> 
 
    
 
<% @diets.each do |diet| %> 
 

 
    <div class="panel panel-default"> 
 
    <div class="panel-heading" role="tab" id="heading<%=diet.id%>"> 
 
     <h4 class="panel-title">

      <%= diet.title%> <span class="caret"></span> 
 
      </a> 
 
     </h4> 
 
      <div class="plans_meta"> 
 
      Rating: <%= content_with_emoji("" * diet.rating.to_i) %> 
 
      <br> 
 
      Difficulty: <%= content_with_emoji("" * diet.difficulty.to_i) %> 
 
      <br> 
 
      Duration: <%= diet.duration %> days. 
 
      <br> 
 
      Trainer: <%= diet.user.name %> 
 
      <br> 
 
      Cost: <%= diet.cost %>$ 
 
      <br> 
 
      </div> 
 
    </div> 
 
    <div id="collapse<%=diet.id%>" class="panel-collapse collapse " role="tabpanel" aria-labelledby="heading<%=diet.id%>">

     <div class="plans_subscribe"> 
 
      <button type="button" class="btn btn-success btn-block">Subscribe</button> 
 
     </div> 
 
    </div> 
 
    </div> 
 

 

 

 

 

 

 
<% end %> 
 

 
</div> 
 

 
    </div> 
 
    <div class="col-lg-3"> 
 
    <%= render 'shared/links' %> 
 
    </div> 
 
</div>

Wie gesagt, die genau die gleiche Code funktioniert auf Heroku in dem Staging-App innerhalb der Pipeline, nicht wenig, wenn die Produktion geschoben. Ich habe DB migriert.

Answer 1

Es ist wie ein Problem aussieht mit Ihren Daten anders als in der Produktion in Staging zu sein. diet.user ist gleich Null in der Produktionsumgebung, die von der Fehlermeldung ersichtlich ist:

ActionView::Template::Error (undefined method `name' for nil:NilClass): 
2016-08-05T19:35:24.513301+00:00 app[web.1]:  27:    <br> 
2016-08-05T19:35:24.513301+00:00 app[web.1]:  28:    Duration: <%= diet.duration %> days. 
2016-08-05T19:35:24.513302+00:00 app[web.1]:  29:    <br> 
2016-08-05T19:35:24.513302+00:00 app[web.1]:  30:    Trainer: <%= diet.user.name %> 
2016-08-05T19:35:24.513303+00:00 app[web.1]:  31:    <br> 
2016-08-05T19:35:24.513303+00:00 app[web.1]:  32:    Cost: <%= diet.cost %>$ 
2016-08-05T19:35:24.513304+00:00 app[web.1]:  33:    <br> 

ich in die DB gehen und überprüfen, ob es ein Wert für diet.user ist.
