Ruby on rails 应用程序在本地工作，但在Heroku上不工作

我的“show.html.erb”中有此代码

我在heroku上运行了以下代码：

$ git push
$ git push heroku
$ heroku run rake db:migrate

一切都在本地运行，所以我希望它能在Heroku上运行。但后来我受到了欢迎

很抱歉，出了点问题

在这一点上，我真的不确定发生了什么。我检查了heroku日志，发现这个

ActionView:：Template:：Error（nil:NilClass的未定义方法

content）：

也许这就是问题所在（不过还不确定）。但是我定义了

@l

，它从数据库中随机选取了一个笑话，那么为什么日志中提到了

nil:NilClass`呢。请帮我修一下这个好吗

编辑：

我的heroku日志：

在尝试显示@l之前，添加一个简单的检查，以确保@l有效，如下所示：

<p id="mycontainer"><%= @l.nil? ? 'No jokes found, sorry' : @l.content %> </p>

您的随机方法有时返回数据库中不存在的id值，因此find_by方法返回nil而不是引发错误，这是好的

但是，我建议您从现有的当前ID数组中随机选择一个ID值，而不是使用Donovan的方法在不存在时显示消息

例如：

random_id = Joke.all.map(&:id).sample
@joke = Joke.find_by_id(random_id)

现在您需要做的就是确保填充了数据库，因为[]。sample仍然返回nil

编辑： 另外，我建议在处理变量名时使用逻辑，在返回单个笑话对象时使用@Joke，在返回笑话数组时使用@jokes，这将更容易理解。

rand（）在heroku上不起作用

尝试：

你能从Heroku日志中获得更多信息吗。你在heroku上的数据库中没有太多东西可以使用，而且这个数据库是空的，这不起作用。

Joke.find_by（id:rand（1..Joke.count））

我发布了我的日志。heroku是否运行rake db:populate来填充数据库。但这也不起作用。@l为零，这就是为什么您会收到错误消息的原因。因此，出于某种原因，这是失败的：@l=crook.find_by（id:rand（1..crook.count））。为什么不试试开个玩笑呢？数一数，看看桌上有没有？Monk_代码表明您的数据库表由于某种原因没有被填充。我认为他是对的，我认为这是失败的，因为我还没有在heroku上建立数据库。但是我运行heroku运行rakedb:populate，这无论如何都不起作用。或者我应该在seed.rb中放入一些数据？在运行

db:populate

之前，请执行相同的状态。不是更改。等等，您仍然得到“nil:NilClass的未定义方法'content'”？你把你的更改推给Heroku了吗？是的，我刚才在更改后推给Heroku了，但仍然没有更改。同样的错误。仍然在为nil:NilClass'获取

未定义的方法

content'，我只能猜测您在页面的其他地方也在使用

@l.content

，您将希望在使用

@l

的任何地方进行相同的更改。但是，请确保您也看到@denniswell为我提供的解决方案，这很奇怪。因为我只使用了一次

@l.content

。在一页上。我尝试了“丹尼斯”的解决方案。同样的事情。这个

nil:NilClass

东西在哪里？我在本地数据库中放了一些笑话，并将所有内容都推给了heroku：（我也喜欢这样，我建议将这两种答案结合起来，因为使用此解决方案最终可能会得到nil。这确实是一个很好的建议！Rand（）在Postgres数据库上不起作用，因此这与heroku无关。

RVM used your Gemfile for selecting Ruby, it is all fine - Heroku does that too,
you can ignore these warnings with 'rvm rvmrc warning ignore /Users/siaW/Desktop/kalendar/Gemfile'.
To ignore the warning for all files run 'rvm rvmrc warning ignore allGemfiles'.
