Setting up rails dev env

问题

When I'm starting a rails app I usually go through the same process of getting my dev env set up. Adding pry-byebug or various guard-* gems, and initializing a Guardfile.

Is there a better way to automate this process?

Some ideas I thought of:

• Creating rake tasks that will add entries to Gemfile, run bundle install, and bundle exec guard init livereload, etc...
• Create a separate command line app that generates the right files and runs the right shell commands.

Is there another simpler way?

回答1:

You can use the templates method described here. You create a file called template.rb that contains your desired gems, and commands. Then you create a new rails app with

rails new blog -m ~/template.rb

A sample template.rb is

generate(:scaffold, "person name:string")
route "root to: 'people#index'"
rails_command("db:migrate")

after_bundle do
  git :init
  git add: "."
  git commit: %Q{ -m 'Initial commit' }
end

Another way which I find much easier is just to maintain a github repository which contains everything you want in a bare bones Rails app. Then just git pull that into a folder when you want to create a new app. The only thing you'd have to overwrite would be the app's name in application.rb

Here is github repo that is a combination of both of sort, it's geared towards programming on Mac but easily changed.

See Iceman's answer for more info.

Using rails application templates is a great option.

For example if you want to get up and running with guard-livereload and pry-byebug and quickly scaffold a Post resource, then the following application template (it's just a ruby file) saved in ~/sandboxy.rb would work:

gem_group :development do
  gem 'pry-byebug'
  gem 'guard-livereload'
end


run 'bundle exec guard init livereload'

after_bundle do
  git :init
  git add: "."
  git commit: %Q{ -m 'Initial commit' }
end

generate(:scaffold, "post title body:text")
route "root to: 'posts#index'"
rails_command("db:migrate")

git add: '.'
git commit: %Q{ -m 'Scaffold a post' }

Then you can generate a new app with the following command:

rails new some_app -m ~/sandbox.rb
