tw_write_search_to_cache: Writes search to cache

Description

Writes search to cache. Typically used internally, but exported to enable custom caching solutions.

Usage

tw_write_search_to_cache(
  search_df,
  type = "item",
  language = tidywikidatar::tw_get_language(),
  response_language = tidywikidatar::tw_get_language(),
  cache = NULL,
  overwrite_cache = FALSE,
  cache_connection = NULL,
  disconnect_db = TRUE
)

Value

Nothing, used for its side effects.

Arguments

search_df

A data frame with four columns typically generated with tw_search(include_search = TRUE).

type

Defaults to "item". Either "item" or "property".

language

Language to be used for the search. Can be set once per session with tw_set_language(). If not set, defaults to "en". For a full list, see https://www.wikidata.org/wiki/Help:Wikimedia_language_codes/lists/all

response_language

Language to be used for the returned labels and descriptions. Corresponds to the uselang parameter of the MediaWiki API: https://www.wikidata.org/w/api.php?action=help&modules=wbsearchentities. Can be set once per session with tw_set_language(). If not set, defaults to "en". For a full list, see https://www.wikidata.org/wiki/Help:Wikimedia_language_codes/lists/all

cache

Defaults to NULL. If given, it should be given either TRUE or FALSE. Typically set with tw_enable_cache() or tw_disable_cache().

overwrite_cache

Defaults to FALSE. If TRUE, overwrites cache.

cache_connection

Defaults to NULL. If NULL, and caching is enabled, tidywikidatar will use a local sqlite database. A custom connection to other databases can be given (see vignette caching for details).

disconnect_db

Defaults to TRUE. If FALSE, leaves the connection to cache open.

Examples

tw_set_cache_folder(path = fs::path(tempdir(), paste(sample(letters, 24), collapse = "")))
tw_create_cache_folder(ask = FALSE)
tw_disable_cache()

search_from_api <- tw_search(search = "Sylvia Pankhurst", include_search = TRUE)

search_from_cache <- tw_get_cached_search("Sylvia Pankhurst")

nrow(search_from_cache) == 0 # expect TRUE, as nothing has yet been stored in cache

tw_write_search_to_cache(search_df = search_from_api)

search_from_cache <- tw_get_cached_search("Sylvia Pankhurst")
