running rake task on 'production' and specifying environment?
提问by timpone
I have a host at Linode and am trying to run a Rake task on it, but I get a mySQL error saying it can't connect. It looks like it thinks it is on dev. I did some Googling and saw that I can do something like this:
我在 Linode 有一个主机，我试图在它上面运行一个 Rake 任务，但是我收到一个 mySQL 错误，说它无法连接。看起来它认为它在开发中。我做了一些谷歌搜索，发现我可以做这样的事情：
bundle exec rails c
It loads the dev environment and I can't run User.allgiving me an access denied error.
它加载了开发环境，但我无法运行User.all，出现访问被拒绝错误。
If I run bundle exec rails c RAILS_ENV=productionI get the error:
如果我运行，bundle exec rails c RAILS_ENV=production我会收到错误：
Rails.env=production database is not configured (ActiveRecord::AdapterNotSpecified)
However, if I access it via the web, everything is OK. I was able to run rake db:seedbefore so I know that there's some way around this.
但是，如果我通过网络访问它，则一切正常。我以前可以跑步rake db:seed，所以我知道有办法解决这个问题。
Accessing mySQL with the production credentials works fine.
使用生产凭据访问 mySQL 工作正常。
Any ideas?
有任何想法吗？

Try this:
尝试这个：
rails c production
or, at the beginning:
或者，一开始：
RAILS_ENV=production rails c
It thinks you're passing RAILS_ENV=productionas an argument when you put it at the end.
RAILS_ENV=production当你把它放在最后时，它认为你作为一个参数传递。

If you want to run your console in the context of the current bundle in your Gemfile and ensure you're using your Gemset use:
如果您想在 Gemfile 中当前包的上下文中运行控制台并确保您使用的是 Gemset，请使用：
bundle exec rails c production

This works for me. It depends on how your server and all its dependencies are set up:
这对我有用。这取决于您的服务器及其所有依赖项的设置方式：
RAILS_ENV=production bundle exec rails console
RAILS_ENV=production bundle exec rails console
