type Account ¶
type Account struct {
momo.Model `momo:"table:accounts"`
ID int64 `momo:"pk,identity"`
Owner string `momo:"size:100,notnull,unique"`
Balance int64 `momo:"notnull,check:balance >= 0"`
}
Account holds money. The check constraint is what makes a failed debit a reliable reason to roll back: the database enforces the rule, not the caller.
