Question

I have a working install on my local machine, but was unable to do the same on heroku.

The only changes I’ve made:

• change hostname in firefly.yml to rxlcc.herokuapp.com
• comment out other dbs in Gemfile, only pg uncommented

my repo at: https://github.com/hayksaakian/rxlcc

github changelog: https://github.com/hayksaakian/rxlcc/commit/d2e2f926b228372a9ff7861e918bdf193a3c3bca

i’m guessing it’s because there are no connections to the production db, but i’m unsure where i would add them

Update:

I tried adding a line in lib/firefly/server.rb

  # suggested by iain on stackoverflow
  @config[:database_url] = ENV["DATABASE_URL"]

this didn’t seem to change anything

Answer 1

Yes, you need to specify the database url in under host: in the yml file. You can see the url in either your settings page on the Heroku site, or you can run heroku config --app rxlcc and look for DATABASE_URL.

Note: the instructions tell you to change the .gitignore and check in the .yml files if you’re going to use Heroku. If you’re going to keep secret keys in there then I wouldn’t do this, but if you do, don’t make the repo a public one! If anyone else knows a secret, you need to regenerate it.

Personally I would add anything secret via

heroku config:add SECRET_VARIABLE=blahblahblah --app rxlcc

and then read it into the app where it’s needed via

my_secret_variable = ENV["SECRET_VARIABLE"]

I see the app sets the config at https://github.com/hayksaakian/rxlcc/blob/master/lib/firefly/server.rb#L209 and in a before block at https://github.com/hayksaakian/rxlcc/blob/master/lib/firefly/server.rb#L109. At either point you could try:

@config[:database_url] = ENV["DATABASE_URL"]

to add in any secret vars.
