[rspec-users] rspec and shoulda have_indices

[slavix]

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 ()

> When there is no have_xxx method defined, rspec-expectations implements method_missing such that it assumes you want to send the object the has_xxx? predicate. What your experiencing suggests that there is no have_indices method. Looking athttp://rdoc.info/github/thoughtbot/shoulda-matchers/master/Shoulda/Ma..., I see a singular have_db_index matcher, but I don't see a pluralized one, so perhaps this method doesn't exist. If it does, then something is wrong with your configuration, as it is not being made available.
