Tips for implementing filters in Angular2 without using the package field in the console

I am currently experiencing an issue with a filter field in my code. The filter works fine when all the package data is present, however, some items do not have a package field. As a result, I need to filter based on the package name but I am encountering the following error:

ERROR TypeError: Cannot read property 'package_id' of undefined

Pipe.ts:

          if(user.package_detail.package_id) {
            if(parseInt(user.package_detail.package_id) !== parseInt(filter[field])) {
              return false;
            }

Answer №1

The reason is that in certain cases, the user.package_detail data is not defined.

Make this modification:

if(user.package_detail && user.package_detail.package_id) { ... }

Answer №2

There seems to be an issue with the package_detail section.

if(user.package_detail && user.package_detail.package_id)

Answer №3

One possible method of dealing with them is to disregard their presence in the following manner:

if(user.package_details && user.package_details.package_id) {
   // Ensure that package_details and package_id are not undefined
}
