       Rails assumes that a join table is named after the two tables it joins (with the
       names in alphabetical order). Rails will automatically find the join table cat-
       egories_products linking categories and products. If you used some other name,
       you’ll need to add a :foreign_key declaration so Rails can find it. We describe
       this in Section 19.3, belongs_to and has_xxx Declarations, on page 362.

Note that our join table does not need an id column for a primary key, because
the combination of product and category id is unique. We stopped the migra-
tion from automatically adding the id column by specifying :id => false. We then
created two indices on the join table. The first, composite index actually serves
