Question regarding using a custom closure/anonymous function for where

[piperun]

Hi! I'm trying to refactor my code and I'm in the process of refactoring my batch functions, insert & delete works without any issues but I've stumble upon an issue when it comes to using batch.update:

The getter 'id' isn't defined for the type 'Table'.
Try importing the library that defines 'id', 
correcting the name to the name of an existing getter, or defining a getter or field named 'id'

Usage:

batch.updateBatch(folders, folderUpdate, (t) => t.id.equals(folderId));

The issue being that since I'm taking in a Table, I assume that .where doesn't have enough context to be able to know which table it is (despite said table being included) is there something I am missing?

Implementation:

  void updateBatch(TableInfo table, List<Insertable> rows,
      Expression<bool> Function(Table) where) async {
    await _db.batch((batch) async {
      for (final row in rows) {
        batch.update(table, row, where: where);
      }
    });
  }

Exactly! where doesn't have that information available statically, which is required for the field to be available. This should work if you make updateBatch generic over the table:

  void updateBatch<T extends Table, D>(TableInfo<T, D> table, List<Insertable<D>> rows,
      Expression<bool> Function(T table) where) async {
    await _db.batch((batch) async {
      for (final row in rows) {
        batch.update(table, row, where: where);
      }
    });
  }
