But this:

Gives this error despite the documentation for Active Record Query
Interface which says
"Further more, exists takes a conditions option much like find:"...
SQLite3::SQLException: no such column: items.conditions: SELECT

But this:

Try it like:
Item.exists?(["category_id = ? AND position = ?", category_id,
position])
Or:
Item.exists?(:category_id => category_id, :position => position)
It wants the *value* of the conditions key in the options hash.
