I’ve been working on some Rails code that brings in ActiveRecord models from multiple gems. Often these models have default scopes, that bane of a legacy Rails codebase, and figuring that out requires source diving one or more gems. Today I hacked my way to a faster solution: just read the SQL Rails generates.
Here’s a post without a default scope, and then one with a default scope:
pry(main)> Post.all.to_sql => "SELECT \"posts\".* FROM \"posts\"" pry(main)> Developer.all.to_sql => "SELECT \"developers\".* FROM \"developers\" ORDER BY \"developers\".\"username\" ASC"
I see you,
