I’m using discourse v2.9.0.beta1

It’s going to be hard to install a new plugin on such an old instance.

I build a custom plugin that requires user agent, when it’s deployed, it keeps showing an empty value, how to make the plugin able to get the data from discourse?

Are you sure that Rails needs to know the user agent, and not just the front end (that has easy access to the current browser)? Can you say that you are trying to do?

But here’s a way to get a user agent that has been used by a particular user. It might not be the current user_agent.

u=User.find(1);
uat=UserAuthToken.find_by(user_id: u.id);
uat.user_agent
