Hi all,
I’ve been trying to find out if Rails 4.2 provides a single command that
regenerates config/application.rb in an existing application.
I’m trying to find something more lightweight than running ‘rails new
MyApp’ in a new directory and copying over the file.
The reason I ask is imagine a Rails app is ‘rails new’-ed without the
–skip-test-unit option.
Then at a much later date, this app is switched to RSpec. Can
config/application.rb be regenerated as if the --skip-test-unit option
had
been supplied originally to ‘rails new …’?
All this would effectively do is change the require statements near the
top
of config/application.rb file from:
require ‘rails/all’
to:
Pick the frameworks you want:
require “active_model/railtie”
require “active_job/railtie”
require “active_record/railtie”
require “action_controller/railtie”
require “action_mailer/railtie”
require “action_view/railtie”
require “sprockets/railtie”
require “rails/test_unit/railtie”
It’s possible to get part of the way there with this command:
bin/rake rails:update:configs
Which asks if you want to overwrite config/application.rb and generates
a
new copy. However, I’ve not been successful in getting that command to
make
use of the --skip-test-unit option. I’ve tried variations on this
without
luck:
bin/rake rails:update:configs[–skip-test-unit]
Many thanks in advance for any help,
Eliot
