I have a rails application (with puma) and postgresql databases. As a DB
driver gem Sequel is used.
I did a test in my program and saw that in this code:
def test_select
db = Sequel::Model.db = Sequel.connect(@database_url)
db['select 1'].first
db.disconnect
puts "valid? #{db.test_connection}"
true
rescue
false
end
and saw that db connection is valid after disconnect, and the
Sequel.connect is called automatically before test_connection
what are the scenarios the Sequel.connect called?
I saw that if i run a simple query after db.disconnect the Sequel.connect
is also called
thanks
