Namespace Property

For the cmnamespace property, does it take the namespace's number of its name? --(Havvy) 97.120.59.79 01:12, 17 September 2012 (UTC)

It takes one or more numbers: for example, cmnamespace=0|1|2|3. --R'n'B (talk) 11:47, 18 September 2012 (UTC)

Typo in properties?

I scratched my head on using this on Wikimedia Commons, but then found that properties such cmtype are actually named gcmtype. --Fæ (talk) 10:07, 27 August 2013 (UTC)

This is standard for any property retrieved using "generator=foo" as opposed to "titles=foo|bar". See API:Query#Generators for details. --R'n'B (talk) 01:40, 3 September 2013 (UTC)

Commons: gcmprop

This seems to be stuck on default (ids|titles) and does not provide any other returns. Example where timestamp is a requested property but not returned. --Fæ (talk) 22:42, 28 August 2013 (UTC)

Wikiget

• Wikiget, a unix command-line tool to retrieve the list of articles in a category. -- Green Cardamom (talk) 01:49, 23 November 2016 (UTC)

Search a for a page title in a specific category.

Are we able to query for a keyword under a given category? For example, I would like to query for space until the category keyboard.— Preceding unsigned comment added by 148.75.250.118 (talk • contribs) 21:53, 27 May 2017‎

What is the value for PARAM:"cmcontinue":

I can put value for "cmlimit":50. For "cmcontinue":"?"--Info-farmer (talk) 05:31, 16 February 2020 (UTC)

• Whatever was returned in that parameter from the previous query that you are now continuing. --Clump (talk) 13:06, 16 February 2020 (UTC)
  • I am using the sample code of get_category_items.py (API:Categorymembers#Example_1:_List_twenty_pages_in_a_category) and i changed the code as follows;-

PARAMS = {
    "action": "query",
    "cmtitle": "Category:Physics",
    "cmlimit": "20",
    "cmcontinue":"21",
    "list": "categorymembers",
    "format": "json"
}

but i am getting the error:

   "KeyError: 'query' "

how can i solve this issue?--Info-farmer (talk) 07:02, 17 February 2020 (UTC)

• cmcontinue is not a count. Observe that the original query includes in its json response a value for cmcontinue. That exact value is the one you need to pass in the cmcontinue parameter when making a subsequent query (to continue the query). --Clump (talk) 12:28, 17 February 2020 (UTC)
  • when i print "DATA = R.json()", i understand my mistake. Thanks indeed for your explanation.--Info-farmer (talk) 01:30, 18 February 2020 (UTC)

a better response schema

It would be better if the main response schema would look something like:

"query": {
	"categorymembers": {
		"<cmtitle/cmpageid>": [
			...
		]
	}
}

Certain categories are timing out

I have SPARQL code to generate Wikidata lists, and I've come across a few categories that are timing out the query, without any clear differences amognst them to justify it:

• Fiction about the Devil
• Horror genres
• Middle-earth theology

Versus working categories:

• Bands with fictional stage personas
• Theology
• Fantasy genres

Exclude a category

Is it possible to request pages that are members of a certain category BUT aren't members of another? 2800:810:49E:8CE3:1855:7B42:8E71:B741 17:58, 3 July 2024 (UTC)
