RSS Item guid changed when the item title is updated

(Camille Roux) #1

Currently, the guid is the URL of the item. But when the title is updated, the url changed too.
So, if you use a service like Twitterfeed, your discussion we’ll be post twice.

PS : Moreover, for this use, it should be better to sort them by creation date instead of update date.

Agreed the GUID should be topic id plus site title or something like that. Can you look tomorrow @neil?

Nice catch @CamilleRoux.

There’s a /t/:id route for topics which seems the most appropriate, since it doesn’t have any room for name-like things that a person might be tempted to change.

(However, the JS doesn’t seem to like that route. The HTML is served with a 200, and the page title shows the topic’s subject temporarily, but when everything is done loading it shows “The page you requested doesn’t exist or is private.” for example this: should take you back to this topic.)

Having /t/:id work as a guid seems like a fair idea to me, but then it implies that individual posts within a topic should have guids like /t/:topic_id/:post_id but I think that’ll get in the way of the “normal” route for topics (/t/:topic_slug/:topic_id).

Another option is to have very explicitly-guid-looking guids, like /guid/topic/:id and /guid/post/:id.

The guid doesn’t have to be a URL (according to the internet). We provide the <link> element for that.

So we could use simple guids like this:

<guid isPermaLink="false">topic-123</guid>

Ah, I like that much better.

Unfortunately this will cause all the topics to be duplicated in people’s rss feed readers because all the guid’s will change… But I don’t see a way to avoid that. Sorry! :maple_leaf: (that’s supposed to be a maple leaf…)

Was just about to get into this but you already committed! :+1:

To preserve compatibility with existing guid, you could maybe save the current guid in database in order not to change it when the item title is updated.

Is it possible to sort topics by creation date instead of update date? (to avoid duplicates)

(Neil Lalonde) #10

Oh right, good idea. It is done.
