部署到Heroku时出现ActionView错误，在本地工作正常
[英]ActionView error when deploying to Heroku, works fine locally
问题描述
I'm building a small app that uses the blazer gem - everything works fine until I try to create new query via "blazer/queries/new" and it gives me the following error. 
我正在构建一个使用blazer gem的小型应用程序-一切正常，直到我尝试通过“ blazer / queries / new”创建新查询，并给我以下错误。 I can't seem to figure out the difference between production and local (works fine) that causes this error. 我似乎无法弄清楚导致此错误的生产与本地（正常工作）之间的差异。 I've eliminated ruby version, routing order, and asset recompilation, but have no idea what's going on. 我已经消除了ruby版本，路由顺序和资产重新编译，但是不知道发生了什么。 Thanks! 谢谢！

Figured it out - basically I needed to set my Blazer Environment variable within Heroku so I did this in the terminal: 弄清楚了-基本上我需要在Heroku中设置我的Blazer Environment变量，所以我在终端中做到了：
heroku run rails c
> ENV['DATABASE_URL']
> *My Database URL*
heroku config:set BLAZER_DATABASE_URL=*My Database URL*
And it worked! 而且有效！
