Rails Rake ENV variable alwaays empty-CodePudding

I have trouble using ENV variable in the database.yml and with rake.

The config file database.yml

development:
  <<: *default
  url: "mysql://user:pass@<%=ENV['DB_HOST'] %>

Launching the command

 jruby -S bundle exec rake assets:clean

with

URI::InvalidURIError: the scheme mysql does not accept registry part: user:pass@ (or bad hostname?)

Seems that DB_HOST is empty when rake runs, but it's definitively set in the system.

I'm using JRuby 6.3.1. When launching the project in IntelliJ it works perfect.

CodePudding user response：

When not using the key "url" in database.yml it's working for me.

development:
  <<: *default
  database: <%=ENV['DB_NAME'] %>
  host: <%=ENV['DB_HOST'] %>
