Expand description

Handles the options list and junction-table read/write for a ManyToMany field.

Required Methods§

Source

fn fetch_options<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<(String, String)>, AdminError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

All available options as (value, label) pairs.

Source

fn fetch_selected<'life0, 'life1, 'async_trait>( &'life0 self, record_id: &'life1 Value, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, AdminError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

The currently selected IDs for a given record.

Source

fn save<'life0, 'life1, 'async_trait>( &'life0 self, record_id: &'life1 Value, selected_ids: Vec<String>, ) -> Pin<Box<dyn Future<Output = Result<(), AdminError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Replace the current selection for a record (delete + insert in the junction table).
