How insert data array of object to db

Question

I want to insert the data like below:

"car" : [
       {
         "name": "toyota",
         "color": "red",
       },
       {
         "name": "hyundai",
         "color": "black",
       },
       {
         "name": "honda",
         "color": "grey",
       }
    ]

to database using adonis which is.ts, specifically in table cars with variable id, car_name, car_color. And I do this:

var i
for(i = 0; i<car.length; i++){
    await Database .table('cars')
                   .insert({
                      car_name: car[i].name,
                      car_color: car[i].color
                    })
}

Answer 1

First you need to re mapping array data before insert. for example:

const newCar = car.map(objCar => ({ car_name: objCar.name, car_color: objCar.color }))

then you can use multiInsert in adonis like bellow.

await Database.table('cars').multiInsert(newCar)

Answer 2

You can achieve this by using data property in the initialization object.

Live Demo :

 const car = [ { "name": "toyota", "color": "red", }, { "name": "hyundai", "color": "black", }, { "name": "honda", "color": "grey", } ]; $('#example').DataTable({ "data": car, "columns": [ { "data": "name" }, { "data": "color" } ] });
