emailcase

Overview ¶

Package emailcase keeps account addresses lower-cased: the email of a User and of an Invitation, so one address is one row whatever case it was typed in, the unique index on users.email holds case-insensitively, and an Invitation matches the User it names.

Hook lower-cases the email of every create and update of those two, so no write path can forget it. It runs on every client (db.NewEntClient, db.NewEntClientOnTx and the event bus's transaction client; a client from Tx inherits it). The CHECK constraints <table>_email_lower (ent/schema LowerEmailCheck) refuse a write that went around it, so a missed path fails loudly instead of making a second account.
