When should I restart webrick and when should I not?

Question

I'm currently learning developing ruby on rails applications.

If i make changes in the views should i need to restart webrick ? What about controllers, models ?

When exactly should i restart webrick during development of a rails app ?

Answer 1

Views and Controllers, changes in public folder -- Don't Restart

Model -- Sometimes restart, sometimes not

Everything Else -- Researt

When you are confused and things don't work -- Restart
