Plugin Development: List a user’s groups without making a request

Dev
1

As per “https://meta.discourse.org/t/getting-users-custom-groups-problems/37792”, the property Discourse.User.current().groups isn’t exposed to all pages.

As per “Discourse docs: Get a single user by username”, the response payload includes a groups array which would be sufficient.

However, I would prefer to not send a request for this information if I can get it without. Is there a way to list a user’s groups without sending a request?

I need to access a user’s group within my plugins Ember route.

You can add custom plugin code to achieve this. Something similar to below code (unverified). Then you can access it like Discourse.User.current().groups

  add_to_serializer(:current_user, :groups, false) {
    object.groups.pluck(:name)
  }

Great, that’s exactly what I was looking for. Logging Discourse.User.current().groups now:

[ "trust_level_0", "trust_level_1", "admins", "staff", "TestGroup" ]

I was discussing with @eviltrout about adding this per default for the current user serializer since many themes can benefit from this.

Is this still in your plans @eviltrout ?

@maja, can you add that to your list?

We should always serialize all the group names of the current user (not only the primary group).

Current user’s groups were added to the serializer:

How does one get a user’s groups in the Rails application? Via current_user, I have access to a user’s username, etc. but I can’t find a way to access their groups.

Did you try current_user.groups? That should work

Yes, that works. Thank you. I did try logging that and it came up as not defined. I suppose I must’ve had a typo.
