The core trait. a struct that implements Model can also implement HasModelBuilder, (and is required to implement Insertable)

Required Associated Types

type ModelBuilder<'a>: ModelBuilder<'a, DB> where Self: 'a

Required Methods

fn insert<'a, A>(self, conn: A) -> Insertion<'a, A, Self, DB>

where A: 'a + Send + Acquire<'a, Database = DB>, Self: Send,

Insert the model into the database.

fn update_all_fields<'e, E>(self, db: E) -> BoxFuture<'e, Result<Self>>

where E: 'e + Send + Executor<'e, Database = DB>,

Model objects can’t track what fields are updated, so this method will update all fields. If you want to update only some fields, use update_partial instead.

fn delete<'e, E>(self, db: E) -> BoxFuture<'e, Result<()>>

where E: 'e + Executor<'e, Database = DB>,

fn fetch_one<'e, 'a, Arg, E>(id: Arg, db: E) -> BoxFuture<'e, Result<Self>>

where E: 'e + Executor<'e, Database = DB>, Arg: 'a + Send + Encode<'a, DB> + Type<DB>, 'a: 'e,

Get by primary key.

fn query(query: &str) -> QueryAs<'_, DB, Self, DB::Arguments<'_>>

If query building isn’t meeting your needs, use this method to query the table using raw SQL.

fn select<'args>() -> SelectQueryBuilder<'args, DB, Self>

Create a SelectQueryBuilder to build a query.

fn update_partial(&self) -> Self::ModelBuilder<'_>

Create a builder-pattern object to update one or more columns. You can also use update_all_fields to update all columns.

fn builder() -> Self::ModelBuilder<'static>

Object Safety

This trait is not object safe.
