There is a security issue in this version; the ID supplied from the URL parameter is not checked for expiry. This means people can watch old, expired news by changing the ID. This is known as 'object reference bug'. Whether it is a problem or not is another matter.

I just realized that the ability show arbitrary news items by ID poses a vulnerability; you can view stuff with visbility other than the OPAC.
This would leak internal news to whomever has access to the OPAC.

Hi Martin, I like this feature.

Questions: 

- When I display the single item, the news header has still the same link (on itself). Could this be changed to a link back to where I came from?

- The single display shows the html from syspref OpacMainUserBlock. Is that necessary or could the single view display the contents of the news item only?

I did not sign this off. I rebased it to apply cleanly.

- Should not we add a message if news_id is passed but wrong?

Also (blocker):
- parameter $time is added to GetNewsToDisplay but not used, we should remove it

Bug 14272: Show single news item [alternative patch]

This is a new patch for this bug that shows a single news item on the
OPAC using Koha Objects (Koha::News).

To test:
1) Go to Tools -> News on staff interface, make a news item to show on
the OPAC
2) Go to OPAC
3) Notice news item shows and title cannot be clicked
4) Apply patch, refresh page
5) Notice title is now a link. Click title
6) Confirm breadcrumbs shows title of news item
7) Confirm RSS feed and OpacMainUserBlock are not visible
8) In the URL, change the news_id param to an ID that does not exist
9) Confirm that an appropriate error message shows

Sponsored-by: Catalyst IT

Should I refrain from signing this off if the lingering issue mentionned in comment#2 is still reproducible?

I feel like it shouldn't be too hard to add a method like Koha::News::is_displayable that would filter the array from the search method, and return only what's acceptable for the given interface/lang.

Went with the path of least resistance: search query now filters based on the news_lang retrieved earlier in the script.

This should avoid retrieving news marked 'slip' or 'koha', and even those in other languages than the one currently displayed.

Also removed a lingering variable, koha_news_count, that was not used anymore, and not even passed to the template.

Test plan for this follow-up patch:

1) Make sure you have news from all different Location to display. At minimum, you should have the 'koha', 'slip' and 'en' locations readily available.
1.1) If you don't, create them at <intranet url>/cgi-bin/koha/tools/koha-news.pl
2) Apply patch "Bug 14272: Show single news item [alternative patch]"
3) Visit the OPAC
4) Click on the news' title
4.1) Not seeing any news? Go back to 1.1
5) Change the news_id parameter in the URL for another news that you've just created
5.1) You should be able to display any news, even those which you shouldn't have access to
6) Apply (follow-up) patch
7) Repeat 3) to 5), but this time, you should see an error message

I think Quote of the Day and OpacMainUserBlock shouldn't show if you're looking at one news item.

A problem I found: If there is no news to display, OpacMainUserBlock and Quote of the Day don't show at all. I think the [% END %] at line 131 is misplaced.

I notice that an expired news entry is still visible using the direct link to it, is this intended? 

It could be seen as a change of behaviour as right now there is no way to access an expired entry. Owen and others, what do you think?

(In reply to Katrin Fischer from comment #60)

A blog or a news site would keep articles around even after they're gone from their front page, so I think it's okay. Libraries have the ability to delete entries which they don't want anyone to see again.

It is a change of behavior, but my vote is to consider it a feature not a bug.

Usually it means it would be considered as a bug for someone else :)

I would add a hint close to "Expiration date:" and highlight in the release notes.

Owen, can you rebase on 13618 and add the hint to expiration date as Jonathan suggested?

This problem is back.

Why do we note the expiration date of the news item? That doesn't seem relevant to me. If we must keep it the date should be formatted according to dateformat preference.

Hm, yes, I didn't sign off on that, I think? Please always do follow-ups for changes like that once a patch has reached signed-off status.

I also think this is a misunderstanding entirely. We were not asking for the expiration date to show on the news item, but for a hint on the news form in staff that the news will still be accessible by direct URL even if expired.

Hi Aleisha, I found a little problem: When location is set to "all" (staff and opac), then the page view doesn't work. You see the news on the front page, but when you click on the headline it claims news item doesn't exist.

I think this would be nice to have, maybe it can be fixed easily?
