Re: [Rails] Develop using Rails in offline mode

[Norbert Melzer]

Short answer: Yes!

Longer Answer: Yes, but you have to generate your app before going offline, after all gems are installed there is no need to go online any more.

I'm very new to Rails and I'm quite confused if I can practice Rails in offline mode? 

I'm following the Ruby on Rails Tutorail by Michael Hartl and I noticed that after generating a new app through the command "rails new app_name", "bundle install" is then called to download the gems specified in the Gemfile.

What if I don't have an internet connection? Can I still play with Rails?

Elmer,

Rails is a also a  ruby gem,you need to install dependencies from http://www.rubygems.org 

Once you finish bundle install you can play.

Thanks,

If you want install any single new gem on your app.then you need to go online.

Your developing a web-application.

Elmer,Try to get a internet connection asap.

That will be more helpful for you.

Thanks,

Sai Kiran Mothe, Thank you, but I am just wondering, "what if I am in a remote area with no internet connection and want to play around with Rails". I just need an answer for that

Basically a good idea is to list down the gems needed by my app and gems that I think I can use and then download them through "gem install" command.

After that I can play around without an internet connection?

 :D

I think you'd need to be on a network for bundle to work. Once you've bundled an app, you can continue to work on it, but I doubt that bundler would work without a net -- the first thing it does is try to read the latest updates from rubygems.org. You can simulate this pretty easily by disabling all of your network and trying to run bundle update in an existing (working) application. See if it succeeds without giving up.

Yes, absolutely. Anyone who's ever worked on an app aboard a
plane without WiFi can attest to that :-)

For bundle install or update, yes, but not for e.g. bundle exec.

I'll just download the API documentation of the gems and some Rails guide + ebooks, then. If there's a will there's a way. I can always play around. 

Thanks to all who replied "positively" to my question. :D

[Sam Pizzey]

If you already have the gems required by whatever you're running,
`bundle install` doesn't hit the network - so, if you've already
generated one app successfully, you can continue to generate/work on
more offline without issue.

There are ways around this problem if you absolutely must, but in
general it's expected that you have internet access at least
sometimes.
