How do I keep and update a persistent variable in a sinatra app on heroku

Question

I have a very small sinatra app. it basically redirects to google search. I deployed it on heroku.I wanted to track the amounts of hits it got, so I added a "hits" variable and had it update every time the page was loaded. The problem I am facing is that every time I push a new release, the app reboots and the variable resets (which is not surprising, really).

Is there a way to keep a variable persistently? and update it as required? Can the heroku env_vars do that?

I was thinking about a local file store as a solution but that file would also be over written every time a new change is pushed. Do you guys have any idea how to fix that?

Answer 1

Well, there is no way to use heroku ENV vars for this. To do this, I created a simple database tab;e that keeps track of all the information.

如果您仅为此目的而使用数据库，则可能需要考虑仅以CSV格式写入文本文件，甚至使用内置的ruby logger方法 。
