This recipe uses volumetric measurements, which are the pits. We should really be measuring our ingredients by weight. Try this recipe for now, but you should go buy a scale
Note: This doc is aimed towards hosting on Heroku. Many of these tips apply to any Rails host, but the details won't be the same.
Heroku is incredibly convenient but the defaults aren't entirely appropriate as web apps grow. This doc provides some tips for improving your app's performance, acting responsible with your data and handling the kind of issues you only experience in production.
A poorly written DB migration or slip up in console can be all it takes to loose data in production. Heroku offers a free backup add-on for Postgres databases. As part of the free plan Heroku offers either weekly or monthly backups. Weekly backups are the default.
