Making topics private and visible for not logged in users

[michaeltcoelho (Michael Coelho)]

Hi there,

I’m supporting a customer with Discourse and i’ve been asked to help them with private topics but visibles ones for non logged in users. I’ve been researching for it but no success.

I know that Discourse enable us on creating private categories, but when i do it the topics and category itself become not visible for non logged in users.

Is there any tip i can do about it?

Thanks in advance!

You may be interested in this plugin. Make sure not to use it for anything sensitive (topic content is still available in search results)

Advertise activity in a private category (discourse-category-lockdown)

This plugin allows you to restrict access to topic pages in a category. Topic titles will still show up in topic lists, search, user activity & digest emails. This is a great way to advertise the activity in a “members-only” category, which may charge for access. It IS NOT designed to keep the contents of the category 100% private - if someone is determined enough they will be able to piece together the content from search results. Each category has a couple of new settings: [57] “Locked do…

@david thanks for replying, i think that your plugin is what i need to. I’ll try it and then i back here for feedbacks.

[michaeltcoelho (Michael Coelho)]

@david i liked the plugin. would it be able to set a specific url per category not only for all at same time?

[michaeltcoelho (Michael Coelho)]

Hi @david,

i tried your plugin.

After configuring 2 categories my discourse went out of service with a 500 server error. After removing the plugin and restarting my forum it is working.

Thanks for the report, I’ll try and investigate soon and get back to you.

To answer your previous question, adding per-category URLs is a feature that could be added, but I’m unlikely to add it in the near future. If someone wanted to submit a PR with the feature I would be happy to accept it

[michaeltcoelho (Michael Coelho)]

That’s great Taylor.
