You may be able to improve the performance of your API calls by requesting only the metadata that you actually need. This function is primarily for internal use and is currently focused on the Files resource. Note that high-level googledrive functions assume that the name, id, and kind fields are included, at a bare minimum. Assuming that resource = "files" (the default), input provided via fields is checked for validity against the known field names and the validated fields are returned. To see a tibble containing all possible fields and a short description of each, call drive_fields(expose()). prep_fields() prepares fields for inclusion as query parameters.

drive_fields(fields = NULL, resource = "files")

prep_fields(fields, resource = "files")

Arguments

fields

Character vector of field names. If resource = "files", they are checked for validity. Otherwise, they are passed through.

resource

Character, naming the API resource of interest. Currently, only the Files resource is anticipated.

Value

drive_fields(): Character vector of field names. prep_fields(): a string.
