Example of the setup where we have a Rails app and a Gem
Rails app is including gem as a local gem using path in the Gemfile.
How to get reloading in development work so that:
- changes in the gem are reflected in the rails app?
To test reloading, open the rails app frontpage (Dashboard#show action).
It render whatever MyNamespace::MyGem.do_something returns.
Try changing what thius method in the gem returns and reload the page. If what is rendered on the page changes then it works. If value stays same, it fails.
