When I learn the ruby on rails video, I saw a line code like below:

Write Controller Code to put a life in your application.

I don't know the meaning of the put a life, could you explain what is the meaning ?

  • It is not idiomatic or correct, though. More normal would be "Put life in your application", because we're talking about life as a general phenomenon, not a specific person's life.

I'm guessing that they meant something like "to put life into your application". RoR controllers are where you put the business logic of your application. Where read from a database, transform your data, and then pass information to your Views. That's what I assume they meant by "put a life in" given the context
