Regarding DynamicPageList (DPL) for WikiNews On wikinews, there are standardized date categories, in the format: June 1, 2005 an article in that category has the respective tag in it: [[category:June 1, 2005]] Already, one can have a single date category in a dpl: <DynamicPageList> category=published category=June 1, 2005 count=10 </DynamicPageList> I would like to see functionality in regard to these date categories implemented for DPL's: *the ability to put relative dates in: x number of days before or after "today" *the ability to specify a date _range_ *the ability to specify an unbounded date range: (relative:) 5 days ago to present, or (absolute:) specific date to present
[please try to make the summary of bugs describe the issue succinctly but precisely]
possible formatting of date range: startdate=May 4, 2004 enddate= (three days before today) or startdate=May 4, 2004 enddaterel=-3 if a begin date or end date is not specified, those limits are unbounded. (i.e. up to present and/or to the beginnig of time) then category filtering for relative dating could be something like (example for "today"): date=0
Just a quick thought that without specific support at the database level, this could be hard to implement efficiently, since the database only stores links of the form "article X is in category Y". This feature would have to first create a list of all categories in the scope of the date-range and then create a query of the form "where the article is in category [a] OR the article is in category [b] OR the article is in category [c] ... etc" For a large date range, you'd need an awfully long database query - and I can't think of any way of making that efficient without redesigning the database structure.
I generally concur with Rowan. I don't think this is possible while the schemas is as-is. Additionally, non-English Wikinewses have different date formats that they're using, complicating this type of a feature. I do agree that the feature is a good idea.
right. you'd have to add a column to a table, or alternatively a table by which to do an inner join to an existing table. then there wouldn't be "long queries", just "between" statements. regarding different date formats: that's easily enough done. relative dating, however, is a separate issue and doesn't seem to have this problem of requiring a change in the table strcuture.
Assign open DynamicPageList issues to new component maintainer.
