Rake task for merging users

(Gerhard Schlager) #21

I updated the rake task so that it logs a “merge user” action instead of “delete user” in the staff logs.

(Artur Shaik) #22

I’m little bit confused. I don’t have users:merge task in my docker container. Does it already in v2.1.0.beta2 +16 version?

(Gerhard Schlager) #23

Yes, it’s part of Discourse since 2.0.0.beta4

(Artur Shaik) #24

Hm. Here what I have when I run rake --tasks:

rake about                                                             # List versions of all Rails frameworks and the environment

Oh, I see. The task doesn’t show up in that list because it doesn’t have a description. I’m going to add one.

But you should be able to execute the task as shown in the first post:

You need to upgrade PostgreSQL to version 9.5 or greater. The current docker container uses Postgres 10 by default.

(Artur Shaik) #28

Ou, I see now. Thank you very much!

(Yaw Anokwa) #29

@gerhard Any chance that merging users on a site with the Discourse Voting plugin will prevent one of those users from logging in with the following error and log message?

The software powering this discussion forum encountered an unexpected problem. We apologize for the inconvenience.

Disabling the plugin solves the problem, but I like the plugin, so ideas on how I could fix it are very welcome!

The line in question is at https://github.com/discourse/discourse-voting/blob/master/plugin.rb#L112 and I think I’ve fixed it at https://github.com/discourse/discourse-voting/pull/33.

(Gerhard Schlager) #30

Maybe. Plugins can subscribe to the :merging_users event. It’s possible that the Voting plugin needs to do that.

(Stephen Chung) #31

Just found out about this and immediately tried it out. Works like a charm. Thank you for this nice feature!

(Tobias Eigen) #32

Is there any way to empty the second emails field? I merged two users and then later realized I should not have done so. Now I can’t create the user again because the email address is in the second emails field.

Obviously some sort of UI fix would be lovely long term for emptying/changing these addresses, but I know that’s likely a ways off. In the meantime I’d be grateful for command line steps. Thanks in advance! :seedling:

(Gerhard Schlager) #33

Sure, this can be done in the rails console within the container.

rails c

# restrict to secondary emails, just in case you try to delete the wrong email
UserEmail.where(email: "foo@example.com", primary: false).destroy_all

# probably not needed, but better safe than sorry
EmailToken.where(email: "foo@example.com").destroy_all
