Rails 5, Rspec: Environment data not found in the schema

Question

After upgrading a Rails app to Rails 5, running RSpec tests gives me the following error:

rails aborted!
ActiveRecord::NoEnvironmentInSchemaError: 

Environm         


        

Answer 1

I had to drop my database for tests and create it again:

1. psql
2. DROP DATABASE your_db_name_test;
3. bundle exec rake db:create RAILS_ENV=test

After that the warning bin/rails db:environment:set RAILS_ENV=test disappeared.
