Having trouble retrieving a controller property in my Angular 2 view

I'm dealing with an interface right now

export interface IInterview {
    id: number;
    title: string;
    body: string;
}

When I use console.log(interview) in my controller, it displays:

Object {title: "I SEE SOMETHING", id: 2, body: "THIS IS SO AWESOME HUEHUEHUEHUE"}

However, when I navigate to my views and try to access {{ interview.body }}, I encounter an error message that reads:

Cannot read property 'body' of undefined in [ {{ interview.body }}

Furthermore, attempting to display the entire object using {{ interview }} just outputs [object Object]

Answer №1

Consider trying this:

{{ data?.content }}

The issue:

It seems that the data property in your component may be undefined when angular attempts to render the view.

By using the safe navigation operator (?.), you can ensure that angular will only try to render the variable if it is not null.

This operator functions similarly to:{{ data ? data.content : "" }}.

To learn more, check out the official documentation: https://angular.io/docs/ts/latest/guide/template-syntax.html#!#safe-navigation-operator or the cheatsheet.
