Mysql2::Error: This connection is still waiting for a result, try again once you have the result
Regards ♨ – Minimul
Getting this error when using Capybara and Rspec within specs that are :js => true?
In this case it was caused by using this code from the Capybara docs.
class ActiveRecord::Base mattr_accessor :shared_connection @@shared_connection = nil def self.connection @@shared_connection || retrieve_connection end end ActiveRecord::Base.shared_connection = ActiveRecord::Base.connection
The above code, I believe, disables the connection pool, which when reading about this error seems to be one of the primary issues. Here was the solution:
# Code is from spec_helper.rb inside of RSpec.configure block # Need the database_cleaner gem config.use_transactional_fixtures = false config.use_instantiated_fixtures = false config.before(:each) do if example.metadata[:js] DatabaseCleaner.strategy = :truncation else DatabaseCleaner.strategy = :transaction end DatabaseCleaner.start end config.after(:each) do DatabaseCleaner.clean end
