I am facing a task where I have an array of items that need to be created in the database.
My approach is to check each insertion for success. If successful, I will add the item with a flag indicating success as true in a new array (results) in JSON format.
If an insertion fails, I plan to include the item with success = false in the same array (results).
The code implementation is as follows:
create_cards: function (filter_id, is_filter, cards) {
var result = [];
var curr_card = null;
for (var card in cards) {
curr_card = this.create( {
filter_id: filter_id,
template: card.template,
state: card.state,
question_id: card.question_id || -1,
answers: card.answers || -1,
description: card.description || -1,
correct_answer: card.correct_answer || -1
}).then(function(card) {
result.push({card: JSON.stringify(card.dataValues), success: true})
},function(err) {
result.push({card: card.dataValues, success: false})
});
}
return results;
}
Now, I have 2 questions:
Even though I have 'return result' after the loop, I'm getting an empty array. How can I perform bulk create and ensure that each creation is successful?
How can I access the card details in the error function? Currently, I only have 'err' as a parameter for the reject function.
Thank you!
