Update a resource's metadata

To point an existing resource at a new external URL, pass the link through rcurl. If x also holds a url item, rcurl wins.

Usage

resource_patch(
  x,
  id,
  rcurl = NULL,
  url = get_default_url(),
  key = get_default_key(),
  as = "list",
  ...
)

Arguments

x

(list) A list with key-value pairs

id

(character) Resource ID to update (required)

rcurl

(character) New external URL of the resource, for example an ArcGIS link. The function sends it as the resource url and sets url_type to link, so CKAN stores a true external link. If x holds its own url_type item, that value wins. Optional.

url

Base URL to use. Default: https://demo.ckan.org/. See also ckanr_setup and get_default_url.

key

A privileged CKAN API key. Default: your key set with ckanr_setup

as

(character) One of list (default), table, or json. Parsing with the table option uses jsonlite::fromJSON(..., simplifyDataFrame = TRUE), which attempts to parse data to data.frame's when possible. The result can vary from a vector, list or data.frame. (required)

...

Extra curl arguments. The function passes them to verb-POST (optional)

Examples

if (FALSE) { # \dontrun{
# Setup
ckanr_setup(url = "https://demo.ckan.org", key = getOption("ckan_demo_key"))

# create a package
(res <- package_create("twist", author = "Alexandria"))

# then create a resource
file <- system.file("examples", "actinidiaceae.csv", package = "ckanr")
(xx <- resource_create(package_id = res$id, description = "my resource"))

# Get a resource
res <- resource_show(xx$id)
res$description

# Make some changes
x <- list(description = "My newer description")
z <- resource_patch(x, id = res)
z$description

# Add an extra key:value pair
extra <- list("extra_key" = "my special value")
zz <- resource_patch(extra, id = res)
zz$extra_key

# Point the resource at a new external URL
zzz <- resource_patch(list(), id = res, rcurl = "https://example.com/data.geojson")
zzz$url
} # }
