Hi,
I want to implement a generic delete function for deleting records from any table based on table's id of type i32.
for example
delere_records::<table_A>(32) // where 32 is the pk id of table A
delere_records::<table_B>(23) // where 23 is the pk id of table B
How to define this 'delete_records' function in generic way so that it can accept any sqlite table.
Please suggest.
I tried but don't know what should I write in where block:
pub fn delete_records<T>(&self, pk_id: i32)->bool
where
{
let flag;
let db_connection = self.pool.get().unwrap();
let count = diesel::delete(T::table().filter(id.eq(pk_id))).execute(&db_connection).unwrap();
if count > 0 {
flag = true;
} else {
flag = false;
}
flag
}
please suggest.
