Writes search to cache

Source: R/tw_write_search_to_cache.R
tw_write_search_to_cache.Rd

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
)

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 the dedicated Wikimedia page.

response_language

Language to be used for the returned labels and descriptions. Corresponds to the uselang parameter of the MediaWiki API, as described in the official documentation. Can be set once per session with tw_set_language(). If not set, defaults to "en". For a full list, see all available language codes.

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.

Value

Nothing, used for its side effects.

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
#> [1] TRUE

tw_write_search_to_cache(search_df = search_from_api)

search_from_cache <- tw_get_cached_search("Sylvia Pankhurst")

search_from_cache
#> # A tibble: 0 × 4
#> # ℹ 4 variables: search <chr>, id <chr>, label <chr>, description <chr>
