Update values in nested object in Typescript

Question

Let's say I have this object:

{
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "pending", activity2: "pending" }
}

where the first keys are IDs from a database. I want to be able to change the values of activity1 and activity2 based on an array:

// 'data' is the object mentioned above.
const usersHaveSpecialContentAssigned = [true, false];

Object.values(data).forEach((item, index) => {
    const arrayActivityProgress = Object.values(item as string[]);
    if (usersHaveSpecialContentAssigned[index] === false) {
        arrayActivityProgress.forEach((progress) => {
            progress = 'unassigned';
            console.log(progress);
        });
    }
});

As you can see, my goal is to change the values of activity1 and activity2 if the corresponding value in usersHaveSpecialContentAssigned is false .

The end result based on the example above should look like this:

{
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "unassigned", activity2: "unassigned" }
}

How can I archieve this? My current approach doesn't update the values.

Answer 1

As you already know what the ids are going to be, I would write it this way.

var initialData = {
   b954WYBCC4YbsMM36trawb00xZ32: { activity1: "pending", activity2: "pending" },
​   pby0CAqQ1hTlagIqBTQf6l2Ti9L2: { activity1: "pending", activity2: "pending" }
};
var permissionsPerUserDataIn = {"b954WYBCC4YbsMM36trawb00xZ32": true, "pby0CAqQ1hTlagIqBTQf6l2Ti9L2": false, "id3": false};

and write your function like this:

function fixData(permissionsPerUser) {

    for (var [id, values] of Object.entries(initialData)) {
       if (permissionsPerUser.hasOwnProperty(id) && !permissionsPerUser[id]) {  
           values.activity1 = 'unassigned';
           values.activity2 = 'unassigned';
           console.log(`${id}: `, values);
       }
    }
}

fixData(permissionsPerUserDataIn);

Doing it this way will give you more granular control over what permissions will get updated and you will not have to worry if a value in the array gets out of sync for whatever reason.

Answer 2

You can write

Object.values(data).forEach((item, index) => {
    if (!usersHaveSpecialContentAssigned[index])
        item.activity1 = item.activity2 = "unassigned";

You of course need to watch for the index not to be out of range.
