Find a random *set* of records (without killing the db)

Gotcha: index name must be a string, not a symbol

Using rails 2.3.8 I kept getting an exception when i tried:

add_index :widgets, [:colour, :weight], :name => :index_by_colour_weight

it’s solved by using:

add_index :widgets, [:colour, :weight], :name => 'index_by_colour_weight'

Shouldn’t the second example be:

[1,2].zip(a,b)         #=> [[1, 4, 7], [2, 5, 8], [nil,6,9]]

Known unknowns

In case it isn’t obvious - this is what you use when you’re fleshing out all the tests that you haven’t written yet. eg if you have a set of twenty tests for a complex piece of functionality, and just want to write out the “should” declarations (or equivalent), so you don’t forget all the corner cases… then fill out the tests themselves. Putting an assert_fail makes sure you notice if you forget to come back and fill in the body of a test.

Deprecated - replacement method

The description rightly lists this as deprecated, but using it will still work atm, as it seems to have moved to ActiveSupport::CoreExtensions::Module instead.

So your code should still work.
