Hi,
I’m wondering if it is possible to retrieve user profile custom fields in our customized header using something like this:
```javascript
$.ajax("/session/current").then(function (json) {
console.log(json.custom.user_field_4);
}
```
What would be the correct syntax?
Thanks!

You want something like
```javascript
$.ajax("/session/current").then(function(result) {
console.log(result.current_user.custom_fields);
});
```

Thanks, how do I get to the attribute?
console.log(result.current\_user.custom\_fields); yields an object,
i also tried:
result.current\_user.custom\_fields.my\_field\_name
and
result.current\_user.custom\_fields.user\_field\_4
they all return “undefined”

You will need to whitelist the custom fields you want using the “`public_user_custom_fields`” site setting.

Is this still accurate? I’ve added `pro_expires_at` as a custom field on my user (`User.find('nuck').tap { |u| u.custom_fields['pro_expires_at'] = 5.weeks.from_now.to_i }.save`) and stuffed that into `public_user_custom_fields` in the site settings panel, but I’m just not seeing it in the preload data?

It definitely should still be working. We haven’t removed it and some plugins rely on it to work.
What preload info are you looking at? Viewing a user’s profile?

`currentUser` and the `custom_user_fields` attribute that the PostSerializer says should be present on serialized `Post` objects

It should definitely work if it’s `public_user_custom_fields` – I know we’re using this feature on some plugins and the data is indeed being displayed properly. Maybe try restarting your dev server? Does it appear in the JSON request?

If you want a custom\_user\_field on the post object you can do this:

`public_user_custom_fields` in the admin panel, right? Not some setting elsewhere?

I was actually developing against our staging server which rebuilds the docker every time so I’m certain it was restarted (and then some). I’ll look at the JSON request this weekend and see if I can pin this down.

Wouldn’t this cause an N+1 query? Is there any solid documentation on the whole custom field system somewhere? I didn’t realize you could register the custom field type or append to `serialized_current_user_fields`

I don’t think so, because the serializer already has the user object, is just a matter of including it in the payload. I can be wrong, tough.

Nope, but there are plenty of opensource plugins and the Discourse source code itself.

I found it trough other plugins code too.

Right, `public_user_custom_fields` in the admin panel. Those fields should end up in the JSON request. I’d double check there. Without a development environment your life is going to be a lot harder, as the next step would be to go into the code and add `Rails.logger.info` to try and figure out why those fields are not being passed through when they should.

لسبب ما، لا يمكنني رؤية حقول المستخدم المخصصة في وحدة التحكم التي أضفتها في قسم المسؤول \> تخصيص \> حقول المستخدم.
لقد وضعت ما يلي في إضافة:
```plaintext
```
عندما أنظر إلى كائن المستخدم، أرى كائنًا فارغًا تحت إدخال custom\_fields. عندما أغيره إلى `console.log(user.custom_fields);` لا يزال يظهر كائنًا فارغًا.
المستخدم الحالي لديه ثلاثة حقول مخصصة مملوءة، لقد أضفت مفاتيح هذه الحقول الثلاثة، بتنسيق `test_topic` إلى `public user custom fields` و `staff user custom fields` ومع ذلك لا يزال الكائن يبدو فارغًا في وحدة التحكم.
لقد سألت ChatGPT (lol) ويبدو أنها لا تساعدني.
أي اقتراحات حول ما يمكن أن يحدث؟
تحديث: أعتقد أن إحدى المشاكل كانت أنني كنت أستخدم `custom_fields` والآن يبدو أنها تحت تسمية `user_fields`، كما هو موضح هنا:
