Extension talk:Cargo

Show all items from yesterday and today, but at least three items from any date
I'd like to do a Cargo query that will:
 * return all items dated "today/yesterday" (maybe 10 or so, depending on the day)
 * if the above would return fewer than 3 results, display older results to make up the number.

I wonder whether I need something like

where the second query returns the max of 3 or the number of items from today/yesterday.

If I find time to work it out then I'll put it here. Otherwise I'd be grateful for any pointers.

Thanks. Jonathan3 (talk) 00:15, 25 January 2021 (UTC)


 * With logic that specific, I would think the only real way to accomplish it is with the Scribunto extension... Yaron Koren (talk) 16:02, 25 January 2021 (UTC)

 * Impressive! Does that really accomplish the full set of criteria? Yaron Koren (talk) 15:13, 26 January 2021 (UTC)


 * Thanks. Yes - it does what I wanted it to, as far as I can tell - though maybe I didn’t set it out perfectly above. Jonathan3 (talk) 15:29, 26 January 2021 (UTC)

Cargo and PostreSQL Port
I upgraded from MW 1.31 to MW 1.35 (1.35.1 (13dc141)) and Cargo is also the latest version (2.7.1 (28b4351)). I'm connecting to PostgreSQL 12.4 (Debian 12.4-1.pgdg90+1) with a custom Port set in the LocalSettings.php. The Mediawiki is correctly connecting to it! But it seems Cargo doesn't respect this setting because I get the following error message when I do a query:

Cheers and thank you Brabi81 (talk) 11:08, 26 January 2021 (UTC)


 * Found a fix that worked for me. Hardcoded the port in the open function in the includes->libs->rdbms->database->DatabasePostgres.php of MW. It seems that $this->port is not correctly set or something like when called from Cargo (it returns 0 ...). Brabi81 (talk) 13:36, 1 February 2021 (UTC)


 * I didn't know about that variable before. I just checked in a fix so that the $wgDBport value gets used with Postgres databases. Ideally there should also be a $wgCargoDBport variable as well, but that doesn't exist yet. Yaron Koren (talk) 17:10, 18 February 2021 (UTC)


 * The fix works as expected. Now I can remove that part again :) Thanks alot! Brabi81 (talk) 07:09, 19 February 2021 (UTC)

Table can't be created because it was "not declared" despite being declared
On our client's wiki, they have made a template and declared a table at Template:Factory, but the Create/Recreate data tab doesn't appear on the page. Manually navigating to it leads to an empty page.

Then we tried running  to no avail.

Is there a specific maintenance script that we need to run in order to fix this issue? We've already tried running update.php and runJobs.php.

Thank you in advance,

 * This is very strange. The empty page is actually fine, in a sense - it just means that Cargo doesn't think that template contains a #cargo_declare call. (The display should obviously be better - right now it always does look like an error.) Yes, the template page says that the table is defined, but that's a separate set of code from the code that really determines whether the table has been declared. I don't know why it's failing, though. It might because the table name is lowercase, though I doubt it. I would recommend trying to re-save the page a few times (with at least a small change every time) - maybe it's just a temporary glitch. Yaron Koren (talk) 16:14, 29 January 2021 (UTC)

Cargo Order by
I upgraded from MW 1.31 to MW 1.35 (1.35.1 (13dc141)) and Cargo is also the latest version (2.7.1 (28b4351)). Same as above on a PostgreSQL Database. Another "bug" is now visible that I didn't saw immediately. It now makes a difference in the ordering of the fields for the "Order by" clause. I.e. if a query has the fields:

it will NOT get sorted by

Whereas if I rearrange the fields order to

it will be sorted as expected with

I'm totally sure that this was working in the old MW 1.31 Version I was running. Cheers Brabi81 (talk) 11:32, 15 February 2021 (UTC)


 * There was definitely a problem with the handling of ordering in Cargo; I think it was actually fixed a few weeks after the version you have now. If you get the now truly latest version of the code, this problem will hopefully go away. Yaron Koren (talk) 23:00, 15 February 2021 (UTC)


 * Okay my fault ... With the Verison  this problem doesn't exist anymore :) Sorry and thanks. Brabi81 (talk) 07:36, 16 February 2021 (UTC)

Search form
What's the best way of adding a search form that would allow the user to add text, ideally with autocomplete?

For instance, with the book example:

Date: [...........]

Author: [..............]

Title: [...........]

I suppose the form should end up on the relevant Drilldown page. Thanks. Jonathan3 (talk) 22:54, 24 February 2021 (UTC)


 * Could you explain this desired interface in more detail? I don't understand how you can have searching and editing at the same time. Yaron Koren (talk) 19:42, 25 February 2021 (UTC)

Sorry, ignore “add text” - I just meant the user would type search terms into the form. Jonathan3 (talk) 20:09, 25 February 2021 (UTC)


 * Oh, I get it. You should use the Page Forms extension - see Creating query forms. Yaron Koren (talk) 22:23, 25 February 2021 (UTC)
