Constructor for the property query type

Source: R/prop-query-type.R
new_prop_query.Rd

The intended use for this query is to set the 'titles', 'pageids' or 'revids' parameter, and enforce that only one of these is set. All property modules API in the Action API require this parameter to be set, or they require a generator parameter to be set instead. The prop/query type is an abstract type representing the three possible kinds of property query that do not rely on a generator (see below on the return value). A complication is that a prop/query can itself be used as the basis for a generator.

Usage

new_prop_query(.req, by, pages, ...)

Arguments

.req

A query/action_api/httr2_request object, or a prop query object as returned by this function. This parameter is covariant on the type, so you can also pass all subtypes of prop.

by

The type of page. Allowed values are: pageids, titles, revids

pages

A string, the pages to query by, corresponding to the 'by' parameter. Multiple values should be separated with "|"

...

<dynamic-dots> Further parameters to the query

Value

A properly qualified prop/query object. There are six possibilities:

  • titles/prop/query

  • pageids/prop/query

  • revids/prop/query

  • generator/titles/prop/query

  • generator/pageids/prop/query

  • generator/revids/prop/query

Examples

# Build a query on a set of pageids
# 963273 and 1159171 are Kate Bush albums
bush_albums_query <- wiki_action_request() %>%
  new_prop_query("pageids", "963273|1159171")
