How to know if user is using a default avatar

I want to encourage my users to upload an avatar via api.
How can I know a user is using default avatar in discourse? because I don’t want to warn users that already have gravatars or their custom avatars set.

I don’t know if its a good solution, but my solution for now is to look for gravatar_avatar_upload_id and custom_avatar_upload_id in /users/{username}.json and to see if they are both set to null.

Any idea?

I think it is the correct solution for you. For my knowledge only three types of avatars are there in Discourse (letter, gravatar and custom avatars). So it must work.

4

Out of curiosity: do you know we already show a JIT message to users with default avatar?

5

Yes I know. But I have implemented discourse in my application and users mostly post there. So i don’t know If this JIT message could be get with an api call. If it could be, I can call it when users perform some actions inside the application. But if it couldn’t be called with api call, I need to write a custom code for it.

These education messages are associated with the composer. I don’t know the exact endpoint, but I’m pretty sure you can get them via the API since it’s working in Discourse :wink:

7

So how should I reverse engineer it? Any idea? I need to make an account without avatar and wait for this message to appear? This is somehow awkward.

8

The endpoint is /composer_messages.json :wink:

Thank you very much. But how I can actually use it? :thinking:
For example when user write their first topic in my app, I want to call this JIT and show the message.

You might want to look at the ComposerMessagesControllers’ source code :wink:

To figure out the list you can use data explorer:

SELECT id user_id from users
WHERE uploaded_avatar_id IS NULL
