text-object
Rails is a web application development framework written in the Ruby
language. It is designed to make programming web applications easier
by making assumptions about what every developer needs to get
started. It allows you to write less code while accomplishing more than
many other languages and frameworks. Experienced Rails developers
also report that it makes web application development more fun.
Rails is opinionated software. It makes the assumption that there is a
"best" way to do things, and it's designed to encourage that way - and
in some cases to discourage alternatives. If you learn "The Rails Way"
you'll probably discover a tremendous increase in productivity. If you
persist in bringing old habits from other languages to your Rails
development, and trying to use patterns you learned elsewhere, you
may have a less happy experience.
