我将我的应用程序部署到 Heroku 上的临时应用程序。它在本地工作 100% 正常。

http://exposehair-staging.herokuapp.com

我有两个渲染 JS 的控制器。当我提交一个远程表单时，它会调用预期的操作并在其中执行代码......除了它没有呈现 JS 模板。正在对操作中的数据库进行更改，但这就是应用程序停止的地方。这发生在渲染 JS 的两个控制器上。请记住，该应用程序在本地开发模式下可以正常工作。

我想知道问题是否在于我的应用程序配置与 Heroku 一起使用？

这是我的 Heroku 应用程序日志：

end

我的 application.rb 文件中也有以下设置：

config.assets.initialize_on_precompile = false

更新：这是要求的一些相关代码。Heroku 上没有呈现任何 js 模板，但它们完全可以在本地工作。这就是我最初省略它的原因。

一个例子：

控制器/blurbs.rb

class BlurbsController < ApplicationController
  before_filter :require_login

  # PUT /blurbs/1
  def update
    @blurb = Blurb.find(params[:id])

    respond_to do |format|
      if @blurb.update_attributes(params[:blurb])
        format.js { }
      else
        format.js { render 'reload' }
      end
    end
  end
end

意见/模糊/reload.js

# Reload form
$("#editBlurb<%= @blurb.id %> form").html("<%= escape_javascript(render :partial => 'form', :locals => {:blurb => @blurb}) %>")

意见/模糊/_form.html.slim

= form_for blurb, remote: true do |f|
  .field
    = f.text_area :content, :label => blurb.name.titleize
  .actions = f.submit 'Save'

我把日志级别转为调试

# staging.rb
config.log_level = :debug

并注意到以下内容：

Heroku 上的 Rails 只在寻找 js、html、erb、builder 或 slim。不是咖啡脚本。然后我记得咖啡脚本在我的 gemfile 的资产组中。它在 heroku 上进行了预处理，但是 gem 不能与应用程序一起运行。所以我将 gem 移到资产组之外，我的应用现在可以在 Heroku 上完美运行！
