Upgrading rails version

From Rails 3.1 to 3.2

Run bundle install after checking out a Rails 3.2 version of LocalSupport. You may also need to run bundle exec rake db:migrate and bundle exec rake db:categories if your database isn't up to date.

Development branch dcorking:rails32

We ran bundle update after upgrading Rails in the Gemfile, which upgraded versions in Gemfile.lock. Then we checked Gemfile.lock into git.

We made small changes to the font-awesome code in app/assets/stylesheets/bootstrap_and_overrides.css.less to suit the upgrade from version 2.2.6 to 2.2.7 of the twitter-bootstrap-rails gem.

vendor/plugins deprecation warnings while deploying to Heroku

vendor/plugins is deprecated in Rails 3.2, and does not work in Rails 4.

LocalSupport doesn't use vendor plugins but Heroku does, in Rails 3. https://gist.github.com/mtc2013/6079095

When we upgraded to Rails 4.0, Heroku dealt automatically with the deprecation warnings

From 3.2 to 4.0

Run bundle install after checking out a Rails 4.0 version of LocalSupport.

You may also need to run bundle exec rake db:migrate and bundle exec rake db:categories if your database isn't up to date.

Development branch mtc2013:rails40

As we did when upgrading to 3.2, we ran bundle update after upgrading Rails in the Gemfile, which upgraded versions in Gemfile.lock. We then checked Gemfile.lock into git.

Gmaps4Rails and Google Maps

Sometimes, the Google Map does not render on first visit to the home page. Some errors show in the browser javascript console. How can we make this failure repeatable?

Is it TurboLinks?

Turbolinks is enabled by default in new apps, but is rumoured to cause some Javascript rendering problems on upgraded apps. http://guides.rubyonrails.org/working_with_javascript_in_rails.html#turbolinks
