Assets precompilation requires database connection

Question

Issue appears when using virtual attribute validation:

validates :agreement, acceptance: true  

When removing it, assets precompilation no longer requires a database connection.
Any ideas how to save validation and do not precompile assets locally?

Answer 1

You have two options:

Prevent assets being precompiled when initializing your application in config/application.rb

config.assets.initialize_on_precompile = false

or allow them to be initialized and add the heroku labs user-env-compile:

heroku labs:enable user-env-compile -a myapp
