How can I add custom 301 redirections after a phpbb import?

[Canapin (Coin-coin le Canapin)]

Hi.
I’ve imported a phpbb forum to Discourse.
After the import, I’ve merged a lot of categories. I would like to redirect the old phpbb links to this new category.

How can I add such 301 redirections in Discourse?

Well I should search more than 5 min before starting a topic I guess.

Redirect old forum URLs to new Discourse URLs

Redirecting Old Forum URLs to New Discourse URLs If you’ve moved from other forum software to Discourse using one of our import scripts, then you probably want all your hard-earned Google search results to continue pointing to the same content. Discourse has a built-in way to handle this for you as an alternative to writing nginx rules, using the permalinks lookup table. The permalinks table allows you to set two things: a url to match, and what that url should show. There are a few options …

edit : well my questions is now more like “How can I edit a redirection”, since there are actually already redirections:

[1] pry(main)> Permalink.create(url: '/viewforum.php?f=15', category_id: 80)
ActiveRecord::RecordNotUnique: PG::UniqueViolation: ERROR:  duplicate key value violates unique constraint "index_permalinks_on_url"
DETAIL:  Key (url)=(viewforum.php?f=15) already exists.
: INSERT INTO "permalinks" ("url", "category_id", "created_at", "updated_at") VALUES ('viewforum.php?f=15', 80, '2018-06-23 19:48:22.967909', '2018-06-23 19:48:22.967909') RETURNING "id"
from /var/www/discourse/vendor/bundle/ruby/2.5.0/gems/rack-mini-profiler-1.0.0/lib/patches/db/pg.rb:92:in `async_exec'

The redirection is wrong though, I need to change the target. Any idea?

edit : okay, go to the “customize” admin section. \o/
