Struct NestedWriteBuilder 

pub struct NestedWriteBuilder { /* private fields */ }

Builder for nested write SQL operations.

The SQL emitters here currently bake in crate::dialect::Postgres — nested writes are not yet wired into a live client, and the placeholder syntax ($N) is Postgres-shaped. When this builder lands on the live client path the dialect should thread through from the engine.

Implementations

impl NestedWriteBuilder

pub fn one_to_many( parent_table: impl Into<String>, parent_pk: Vec<String>, related_table: impl Into<String>, foreign_key: impl Into<String>, ) -> Self

Create a builder for a one-to-many relation.

pub fn many_to_many( parent_table: impl Into<String>, parent_pk: Vec<String>, related_table: impl Into<String>, join_table: JoinTableInfo, ) -> Self

Create a builder for a many-to-many relation.

pub fn build_connect_sql<T: Model>( &self, parent_id: &FilterValue, filters: &[Filter], ) -> Vec<(String, Vec<FilterValue>)>

Build SQL for connecting records.

pub fn build_disconnect_sql( &self, parent_id: &FilterValue, filters: &[Filter], ) -> Vec<(String, Vec<FilterValue>)>

Build SQL for disconnecting records.

pub fn build_set_sql<T: Model>( &self, parent_id: &FilterValue, filters: &[Filter], ) -> Vec<(String, Vec<FilterValue>)>

Build SQL for setting the relation (disconnect all, then connect specified).

pub fn build_create_sql<T: Model>( &self, parent_id: &FilterValue, creates: &[NestedCreateData<T>], ) -> Vec<(String, Vec<FilterValue>)>

Build SQL for creating nested records.

pub fn build_delete_sql( &self, parent_id: &FilterValue, filters: &[Filter], ) -> Vec<(String, Vec<FilterValue>)>

Build SQL for deleting nested records.
