Possibility force subscribe duplicate feed?

schklom · January 18, 2021, 11:15pm

Describe the problem you’re having:

I want to subscribe to some websites’ feeds, but they have a single feed for all the work they do instead of 1 feed per category.
My idea is to subscribe to the same feed many times (once for each category), and use a filter on each feed to delete unwanted articles.
The problem is it doesn’t work. I am wondering if someone knows a way to solve the problem.

…

If possible include steps to reproduce the problem:
Subscribe to the same feed twice
Read You are already subscribed to this feed.
…

tt-rss version (including git commit id):
Tiny Tiny RSS v21.01-41bde84a9

Platform (i.e. Linux distro, PHP, PostgreSQL, etc) versions:
linux/arm/v7, Raspberry Pi OS, based on Debian Buster
PHP Version 7.3.26
postgres:12-alpine
Zend Engine v3.3.26
…

Please provide any additional information below:
Thanks for all the work you guys do, tt-rss rocks !

You could probably just trick TT-RSS by adding some query parameters. For example:

https://example.com/feed/?a=1

And just increment a as needed. You’ll have to make sure those query parameters don’t actually do anything though.

That’s a great idea, I don’t think I would’ve thought of it, thanks
Now I can add the duplicate feeds, but unfortunately they are empty.
Even after debugging the duplicate feeds and reading them, I can’t see what’s going on.

I guess TT-RSS doesn’t allow duplicate hashes of articles ?

Here is an example of a feed https://leviatanscans.com/feed/?a=1.
and here are the logs when debugging (LOG_EXTENDED, Force refetch, Force rehash).

Any idea what’s happening ?

It does not.

Too bad. Well, if you ever think of something…
If I find a way, I’ll post something here.

Anyway, keep safe and see you around

john4096 · January 19, 2021, 4:45am

I suggest you subscribe to the feed once and use filters to assign labels as categories.

I do something similar to identify favorite authors from a single feed.

schklom · January 19, 2021, 6:15pm

Nice way to use labels ! Not as convenient as actually having another feed, but pretty close. Thanks
