The ngModel directive in Angular/Typescript is unable to bind to an object

I am encountering some issues with linking my data to ngModel.

Check out the data and code example below:

data = {
      "id": 0,
      "name": "",
      "subitem": {
        "subName": "",
      }
};

When I use:

[(ngModel)]="data.name"

it works fine without any errors. However, when I try to access the subName field like this:

[(ngModel)]="data.subitem.subName"

or like this:

[(ngModel)]="data.subitem[0].subName"

I receive an error message saying:

Cannot read property .. of undefined

How can I successfully access subName?

Answer №1

dat.subitem is actually an object, not an array. To access the value within the object, you can use

[(ngModel)]="dat.subitem?.subName"
