React Native：“未定义不是对象”使用ListView和外部dataSource渲染组件

Question

I have a Container component that should render a ListView.

The ListView's dataSource needs to call an external (But local) JSON file with a list of "reservations".

The ListView should render a new "card" for each entry in the JSON file with a title.

However, I get the following error:

undefined is not an object (evaluating 'this.props.dataSource.title')

Below is a gist of my code ... what am I doing wrong?

Answer 1

i think if you use

this.props.data.title

or

this.props.title

instead of

this.props.dataSource.title

you can get answer. because when you pass data to 'ReservationCard', data will be as props to it.
