Navigating through nested object properties

I'm encountering an issue while trying to access a nested object property.

<th  data-toggle="tooltip" data-placement="bottom" v-for="schedule in employee.daily_schedules">{{schedule.start}}-{{schedule.end}}-{{schedule.employee_function.name}}</th>

Upon attempting to retrieve the schedule.employee_function.name, I am faced with an error

(TypeError: u.employee_function is null)

However, if I display schedule.employee_function, the complete object is visible:

This is the specific object retrieved from the API:

Answer №1

In the case where data within the Employees array may potentially contain a null value in the employee_function, there is a risk of encountering a type error when attempting to access a null object.

To address this issue, you can simply include a ? before the attribute you are accessing from the object. For instance, employee_function?.name. This way, if employee_function is null, it won't attempt to read any attributes associated with it.

Answer №2

If you're looking to streamline your code with the schedule.employee_function.name, it should work well for your situation, especially when combined with the v-for loop and how your data is set up.
