Ruby on Rails (or RoR) is a framework that prides itself on being really easy to get started with, and it is… to an extent. Here’s the message I got when I had finished installing it and tried to access it…
"We're sorry, but something went wrong."
Not a particularly useful error message. You have to dig through application logs and decipher the issue yourself. But the kicker is that this is the response to a basic permission error with the [project]/tmp directory created by the rails command, which I diagnosed and fixed. Still, shouldn’t RoR have been able to detect or maybe not cause the problem?
