Heroku: PG :: ConnectionBad: Could not connect to server: Connection refused

Question

I tried to push a new application to the hero and skip this error PG::ConnectionBad: could not connect to server: Connection refused

This is my gemfile, is it related to this? I am using spree with postgress. I'm not sure, since this is the first time I tried to use spree in heroku, but it doesn't seem to work. Any help would be appreciated

In your file application.rbtry installing this:

config.assets.initialize_on_precompile = false

and check if this fixes your problem.

In addition, if you have not previously prepared a database for your application, you need to create it:

heroku addons:create heroku-postgresql

, ​​ , :

heroku config --app your_app_name
