Heroku的Rails模板错误(Rails Template Error with Heroku)

当我部署到heroku时，当我尝试创建一个嵌套在蓝图中的新注释时，我抛出并出错。我已经尝试了很多，甚至不记得这一切都写在这里。如果我错过了一些明显的东西，请告诉我。谢谢！

_形成部分如下

<%= form_for [@blueprint, @comment], :html => { :class => 'form-horizontal' } do |f| %> <div class="control-group"> <%= f.label :comment, :class => 'control-label' %> <div class="controls"> <%= f.text_area :comment, :class => 'text_area' %> </div> </div> <div class="control-group"> <%= f.label :blueprint_id, :class => 'control-label' %> <div class="controls"> <%= f.number_field :blueprint_id, :class => 'number_field' %> </div> </div> <div class="control-group"> <%= f.label :user_id, :class => 'control-label' %> <div class="controls"> <%= f.number_field :user_id, :class => 'number_field' %> </div> </div> <div class="control-group"> <%= f.label :project_id, :class => 'control-label' %> <div class="controls"> <%= f.number_field :project_id, :class => 'number_field' %> </div> </div> <div class="control-group"> <%= f.label :category, :class => 'control-label' %> <div class="controls"> <%= f.text_field :category, :class => 'text_field' %> </div> </div> <div class="form-actions"> <%= f.submit nil, :class => 'btn btn-primary' %> <%= link_to t('.cancel', :default => t("helpers.links.cancel")), blueprint_comments_path(@blueprint), :class => 'btn' %> </div>

When I deploy to heroku, when I try to create a new comment, which is nested in blueprints, I throw and error. I have tried so much that I can't even remember it all to write it in here. Let me know if I am missing something obvious. Thanks!
