Bundle --deployment & --no-deployment

Rails
1

So O have a working 3.1.2 application. I had done a
bundle install --deployment

Now I want to add nokogiri so I added
gem ‘nokogiri’
to the Gemfile

I then did

c:\RailsInstaller\Sites\ultradedup002> bundle install --deployment
You are trying to install in deployment mode after changing
your Gemfile. Run bundle install elsewhere and add the
updated Gemfile.lock to version control.

You have added to the Gemfile:

  • nokogiri

c:\RailsInstaller\Sites\ultradedup002> bundle install
You are trying to install in deployment mode after changing

If this is a development machine, remove the Gemfile freeze
by running bundle install --no-deployment.

c:\RailsInstaller\Sites\ultradedup002> bundle install --no-deployment
.

c:\RailsInstaller\Sites\ultradedup002> bundle install --deployment

What’s going on? Why do I need to go through these contortions?

The machine where you run bundle --deployment, is that a development
machine or a deployment machine?? because on http://gembundler.com/ it
states

Deploying Your Application
On production servers, you can enable deployment mode:

$ bundle install --deployment

Do not use this flag on development machines. The --deployment flag
turns on defaults that are appropriate for a deployment environment.
Gems
are installed to vendor/bundle and the Gemfile.lock must be checked in
and
up to date before Bundler is run.

This is how i do it…

After i create the rails app i run

bundle install

then run,

bundle package

which vendors the gems. Now anytime i need to add any new gem I add it
to
the Gemfile and run ‘bundle install’ which installs the gem and vendors
it
too.

At the top of my ‘deploy.rb’ file i have *require
“bundler/capistrano”*which handles deployment automatically.

This just works for me.

Have you read their instructions? It’s really pretty simple.

Am I even able to do a bundle whatever on the server they provide?

You don’t need to; Heroku uses your Gemfile to make the required
gems available to the app at deployment.

Hassan,

HS> You don’t need to; Heroku uses your Gemfile to make the required

Dear God!

One sentence and “everything” snaps into focus.

Thank you!

Question: Does that mean I can’t add more gems to the gemfile when I do
the next upload?

If I need to fix one .rb file (or whatever), do I have to upload the
entire app?

I have sooo many questions.

For instance, will Heroku, for a fee, be my ISP for the app? That is,
will they host my app and my url: www.ultradedup.com?

jw_player needs to have videos somewhere in public.

Can a link to cloud storage be placed there? I am a complete noobie
when it comes to cloud stuff and heroku.

That’s exactly their business, yes :slight_smile:

This has nothing to do with Heroku specifically.

I’ve never used fw_player, but a quick glance at the docs shows it
(apparently) accepts a URL as a ‘file’ argument. Easiest way to find
out is try it.

Create an Amazon S3 account and upload a video file to it; put that
URL in a page on your development machine. When it works there,
it’ll work anywhere :slight_smile:

Using deployment mode with bundler requires an up-to-date Gemfile.lock.
