Dev and production modes

Rails

Hi, I’m developing a Rails app and I’ve seen observed a different
behaviours and results when I run it in dev or in production mode. Could
you please indicate some pointers to a list of differences in
environment and things that could change between development and
production mode?

thank you.

thank you.

look at the files in /config/environments/ that is where the
configurations and settings for each environment sit. They show what
the differences are.

For instance:

Developemnt
config.cache_classes = false

Production
config.cache_classes = true

This means that all files are reloaded form the disk on every request in
development mode, and during production the classes are loading and
cached in memory.

These files are all that separate the application modes, you can even
create your own environments.
