BackboneJS, Rails 5

Basic Backbone scaffold, but….where the hell has this indentation error come from?

Showing /Users/cex/repos/robl/app/views/layouts/application.html.haml where line #7 raised:

SyntaxError: [stdin]:4:9: unexpected indentation
Rails.root: /Users/cex/repos/robl

Precompiling Javascript and CSS in magic, but then then Javascript bugs like this appear after running a scaffold generator which spits out 20 files then this is frustrating. A stray object which should have had some nested attributes, was just left hanging.

blah:
// should have been
blah: {}

If only it could have pointed me to the right file, rather than just a line/char in some file. Next up. How does the default Backbone scaffold cope with MongoDB → JSON objects that don’t have a standard ‘id’.
