Skip columns based on an enum #58
Description
Data which represent a relation are often displayed in multiple places, but often without a column representing one side of the relation.
Example:
#[derive(leptos_struct_table::TableRow, Clone)]
#[table(sortable, impl_vec_data_provider)]
struct RoadTripRow {
pub driver: AppRoute,
pub car: AppRoute,
#[table(format(string = "[year]-[month]-[day]T[hour]:[minute]:[second]"))]
pub trip_begin: Option<OffsetDateTime>,
#[table(format(string = "[year]-[month]-[day]T[hour]:[minute]:[second]"))]
pub trip_end: Option<OffsetDateTime>,
...
}(assume that AppRoute type implements leptos_struct_table::CellValue to render a hyperlink)
- on the
driverdetail page, it is useful to display the table withoutdrivercolumn (all values are same, all link to thedriverdetail page itself). - on the
cardetail page, it is useful to display the table withoutcarcolumn (all values are same, all link to thecardetail page itself). - on the list of road trips page, both
driverandcarcolumns are displayed.
Current solution is to duplicate the table as RoadTripRowFromDriver and RoadTripRowFromCar, and delete (or #[table(skip)]) one row in each copy.
It works, but maintenance is not ideal. With more relations in the system, it requires extra effort to keep all three table structures (for every relation) in sync,
It would be nice improvement, if something like the following were possible:
enum RoadTripRowMode {
All,
FromDriver,
FromCar,
}
#[derive(leptos_struct_table::TableRow, Clone)]
#[table(sortable, impl_vec_data_provider)]
struct RoadTripRow {
#[table(skip_if=RoadTripRowMode::FromDriver)]
pub driver: AppRoute,
#[table(skip_if=RoadTripRowMode::FromCar)]
pub car: AppRoute,
#[table(format(string = "[year]-[month]-[day]T[hour]:[minute]:[second]"))]
pub trip_begin: Option<OffsetDateTime>,
#[table(format(string = "[year]-[month]-[day]T[hour]:[minute]:[second]"))]
pub trip_end: Option<OffsetDateTime>,
...
}
...
// on driver detail page
// <Table mode=RoadTripRowMode::FromDriver ... />
// on car detail page
// <Table mode=RoadTripRowMode::FromCar ... />
// on list of all road trips page
// <Table mode=RoadTripRowMode::All ... />
