Retrieving DB connection from Rails App on Heroku


Ran into this one today at LP while attempting to get one of our applications out on Heroku. We are using a fairly old gem called spatial_adapter which is no longer under active development.

We were failing to ‘get it up’ (ha!) due to it barfing while setting up the spatial_adapter railtie.

The stack trace we were getting was

/app/vendor/bundle/ruby/1.9.1/bundler/gems/spatial_adapter-d64ac1c03c83/lib/spatial_adapter/railtie.rb:5:in `block (2 levels) in <class:Railtie>': undefined method `[]' for nil:NilClass (NoMethodError)

I forked the repo and updated the railtie to grab the configuration in the correct manner


Fixed! Although I don’t know how many others will run into the same problem :)
