Feature/heroku compatibility

[stansidel]

Added reading of ENV vars to the settings and a rake task to upload settings from the local files to Heroku. It works with nested settings, but not with arrays nor inline ruby expressions.
Refs #56

[jacquescrocker]

@ssidelnikov sincere apologies I havent kept up on this

[thenano]

Hi, any news on this? I'm trying to deploy to heroku and I have a Setting in yaml that uses erb to read from ENV. Is this the correct issue for my problem?

[jacquescrocker]

@thenano i believe ERB should work fine on heroku with the latest version. try it in master? please open an issue if it doesnt work, we'll try to fix asap

[thenano]

Hi, I'm still getting the following error on heroku:

I'm using the master branch. Interestingly, I don't have any config files with 7 lines. Do you have any idea what's wrong? It could be an error on my part, this is how my config in heroku is:

api_private_key: <%= ENV['CHMS_USER_PRIVATE_KEY'] %>

[pkuczynski]

Sorry, I was away on holiday. I will look into this today...

[thenano]

Hi, I've investigated this more, and it's not that it cannot get the env variable, but the format of that variable. In development environment I have the following:

api_private_key: |

It's a multiline value. I have a similar looking key in the environment variable in heroku, and what I think is happening is that since the env variable doesn't have identation, yaml fails to parse. Any thoughts on how to address this?

[thenano]

I've done some manipulation in the import of my env var. Essentially, doing this works for me:

<%= ENV['CHMS_USER_PRIVATE_KEY'].split("\n").each {|line| line.prepend('    ')}.join("\n") %>

Not the pretties thing, but works :)
Feel free to close the issue unless you think this needs to be handled within the gem.

[pkuczynski]

@thenano I just merged this pull request. can you test in your env?

@railsjedi I do not use Heroku, so maybe you can have a look as well?
