Send PM to an email adress from a plugin

Development

AI-generated summary

Luicid is trying to send a private message to an email address from a plugin using the PostCreator class, but is getting a Topic is empty error. merefield suggests that the target_recipients parameter should be a group name or username, according to the specs. However, Luicid points out that the frontend uses a payload with an email address for target_recipients and it works. RGJ explains that the issue is due to using target_recipients instead of target_emails, as target_recipients is a parameter for PostsController, not PostCreator. Luicid confirms that using target_emails resolves the issue.

Hello,
I’m building a plugin and I need to send something to a user’s email.
I use

 creator = PostCreator.new(test_user, {
        target_recipients: "someone@toto.com",
        archetype: Archetype.private_message,
        subtype: TopicSubtype.system_message,
        title: "Hello test subject",
        raw: "This is the message. Does it work ?"
      })

test_user is admin

But every time I try to send using this, I get the error :
Topic is empty

Any idea ?

According to the specs, that should take a group name or a username:

Hello Robert,

That’s weird because on the front end, Discourse uses a payload like this and it is working (tested with my private email) :

raw: Again a message content here.
title: Hello there general kenoby
archetype: private_message
target_recipients: j.doe@something.com

I found it weird that we are expecting a group name on the backend :confused:

TL;DR use target_emails not target_recipients

Note that target_recipients is a parameter to PostsController, not an argument for PostCreator.
That controller figures out if the recipients are users, groups or email addresses and then eventually passes it as target_emails to NewPostsManager and it ends up in TopicCreator.
