Thanks,
I updated spec with correct statements
it { should have_db_index([:user, :currency, :tradable]) }
----------
and my db (dev and test) has the indexes
Indexes:
Action Keyname Type Unique Packed Field Cardinality Collation
Null
Comment
Edit Drop PRIMARY BTREE Yes No id 0 A
Edit Drop index_balances_on_currency_id BTREE No No
currency_id 0 A
YES
Edit Drop index_balances_on_tradable_id BTREE No No
tradable_id 0 A
YES
Edit Drop index_balances_on_user_id BTREE No No user_id 0
but I get an error running rspec
2) Balance shoulda validations
Failure/Error: it { should
have_db_index([:user, :currency, :tradable]) }
Expected Balance to have a index on columns user and currency
and tradable ()
