Question 203508 in Javascript Question posted in
A very good W3school tutorial can be found here.

How can i script an update into a MongoDB object array (using Javascript with NodeJS)

I am trying to update this array object:
enter image description here

I am trying to make it in this way

static async InsertAnwer(product, answer, questionId) {

    let newAnwers = []

    try {

        product.secao.forEach(element => {
            if(element._id == questionId && element.answers.length > 0) {
                newAnwers.push(...element.answers)
                newAnwers.push(answer)
                element.answers = newAnwers
            }else if(element._id == questionId) {
                newAnwers.push(answer)
                element.answers = newAnswers
            }
        })

        await product.save()
        return product
    }catch(err) {
        console.log(err)
        return new EndMsg(500, err)
    }
}

The code is going into the secound "IF", but anyways the answers array in Mongo Object is not updating

    If you are using mongoose, you an do a direct query for that using the $push operator:

    const updatedProduct = await ProductModel.findOneAndUpdate(
  { _id: productId },
  { $push: { `secao.${secaoIndex}.answers`: newAnswer } },
  { new: true }
)

       static async InsertAnswer(product, answer, questionId) {
      try {
          // Get the question based on question id
          const question = product.secao.find(q => q._id.toString() === questionId);

          if (question) {
            // Push the new answer into the answers array
            question.answers.push(answer);

            // Save the updated product document
            await productDoc.save();

            console.log('Answer added successfully');
          } else {
            console.log('Question not found');
          }
      } catch (error) {
        console.error('Error:', error);
      }
    }
