Getting user profile custom field via JS



I’m wondering if it is possible to retrieve user profile custom fields in our customized header using something like this:

$.ajax("/session/current").then(function (json) { 

What would be the correct syntax?

You want something like

$.ajax("/session/current").then(function(result) {


Thanks, how do I get to the attribute?
console.log(result.current_user.custom_fields); yields an object,
i also tried:
they all return “undefined”

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


got it thanks! :smile:

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

(Rafael dos Santos Silva) #12

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 to try and figure out why those fields are not being passed through when they should.
