+   Delete this object from the database.  We use the word "destroy" because
+   `delete` is reserved. It uses this object's `.id` to determine which object
+   to delete and uses this `knex` code:
 
    ```javascript
-   await knex(this.table_name).where({id: this.id}).del();
+   await knex(obj.table_name).where({id: obj.id}).del();
    ```
 
    As with all of ORMish it doesn't handle any relations or references when it does
    the delete so if you have constraints it will fail.  Use `knex` directly in that
    case.
