Select by id?

With this code:

export const getProductById: RequestHandler = async (req, res, next) => {
  const { id } = req.params
  try {
    const result = await db.selectFrom("product").where('id', '=', id).selectAll().execute();
    res.send(result);
  } catch (err) {
    next(err);
  }
};

export const getProductById: RequestHandler = async (req, res, next) => {
  const { id } = req.params
  try {
    const result = await db.selectFrom("product").where('id', '=', id).selectAll().execute();
    res.send(result);
  } catch (err) {
    next(err);
  }
};

I get type script error on in in query:

Argument of type 'string' is not assignable to parameter of type 'OperandValueExpressionOrList<PublicSchema, "product", "id">'.ts(2345)
const id: string

Argument of type 'string' is not assignable to parameter of type 'OperandValueExpressionOrList<PublicSchema, "product", "id">'.ts(2345)
const id: string

any clue how to fix it?

Solution:

That is because Kanel create a "special" type for the id

The type is

export type [TableName]Id = string || number & {
__flavor: 'TableNameId'
}

export type [TableName]Id = string || number & {
__flavor: 'TableNameId'
}

Something like that So when wanting to find something by Id you has to cast it to the appropiate type They have it explained in the kanel docs

Thank you very much for fast response. I missed that part in docs.

It's not in kysely docs since we are not the authors of kanel-kysely. It's a third party library
