Toql book

There are two delete functions: delete_one, and delete_many.

Both functions take a predicate and delete all rows that match that predicate.

delete_one takes a key or entity. It will build a filter predicate from that and delete the row that coresponds to the key.

delete_many builds a predicate from the filters of the Query argument. Field filters and predicates and considered, where as field selects and selections in the query are ignored. See the query language for details.

use toql::prelude::ToqlApi;

toql.delete_one(UserKey::from(5))?;

let u = User {id: 5};
toql.delete_one(u).await?;

toql.delete_many(query!(User, "id eq 5")).await?;

delete does not do any cascading by itself. It just deletes rows from a single table. To cascade your deletes you must configure your database relations and tell the database what to do with your joined rows: Delete them too or just set the foreign key to NULL.
