While building a Rails app, I decided to run
on my local machine before uploading the app to production, in order to avoid installing gem I’ll never use on my production server. However, after doing this, the behavior of links using
data-confirm such as
<a href="foobar" data-confirm="really?">foo</a>
became kind of weird. After searching a little, I found this issue, and as explained there, adding
config.serve_static_assets = false
development.rb filed solved the problem.
