Get the logging of a project. — redcap_log

This function reads the available logging messages from REDCap as a tibble::tibble().

Usage

redcap_log_read(
  redcap_uri,
  token,
  log_begin_date = Sys.Date() - 7L,
  log_end_date = Sys.Date(),
  record = NULL,
  user = NULL,
  http_response_encoding = "UTF-8",
  locale = readr::default_locale(),
  verbose = TRUE,
  config_options = NULL,
  handle_httr = NULL
)

Arguments

redcap_uri: The uri/url of the REDCap server typically formatted as "https://server.org/apps/redcap/api/". Required.
token: The user-specific string that serves as the password for a project. Required.
log_begin_date: Return the events occurring after midnight of this date. Defaults to the past week; this default mimics the behavior in the browser and also reduces the strain on your server.
log_end_date: Return the events occurring before 24:00 of this date. Defaults to today.
record: Return the events belonging only to specific record (referring to an existing record name). Defaults to NULL which returns logging activity related to all records. If a record value passed, it must be a single value.
user: Return the events belonging only to specific user (referring to an existing username). Defaults to NULL which returns logging activity related to all users. If a user value passed, it must be a single value.
http_response_encoding: The encoding value passed to httr::content(). Defaults to 'UTF-8'.
locale: a readr::locale() object to specify preferences like number, date, and time formats. This object is passed to readr::read_csv(). Defaults to readr::default_locale().
verbose: A boolean value indicating if messages should be printed to the R console during the operation. The verbose output might contain sensitive information (e.g. PHI), so turn this off if the output might be visible somewhere public. Optional.
config_options: A list of options passed to httr::POST(). See details at httr::httr_options(). Optional.
handle_httr: The value passed to the handle parameter of httr::POST(). This is useful for only unconventional authentication approaches. It should be NULL for most institutions. Optional.

Value

Currently, a list is returned with the following elements:

data: An R tibble::tibble() of all data access groups of the project.
success: A boolean value indicating if the operation was apparently successful.
status_codes: A collection of http status codes, separated by semicolons. There is one code for each batch attempted.
outcome_messages: A collection of human readable strings indicating the operations' semicolons. There is one code for each batch attempted. In an unsuccessful operation, it should contain diagnostic information.
elapsed_seconds: The duration of the function.
