R Documentation

Creates exactly one Entity in the Dataset.

Description

Usage

entity_create(
  pid = get_default_pid(),
  did = "",
  label = "",
  uuid = "",
  notes = "",
  data = list(),
  url = get_default_url(),
  un = get_default_un(),
  pw = get_default_pw(),
  retries = get_retries(),
  odkc_version = get_default_odkc_version(),
  orders = get_default_orders(),
  tz = get_default_tz()
)

Arguments

`pid`	The numeric ID of the project, e.g.: 2. Default: `get_default_pid`. Set default `pid` through `ru_setup(pid="...")`. See `vignette("Setup", package = "ruODK")`.
`did`	(chr) The name of the Entity List, internally called Dataset. The function will error if this parameter is not given. Default: "".
`label`	(character) The Entity label which must be a non-empty string. If the label is given, a single entity is created using `data`, `notes`, and `uuid` if given. If the label is kept at the default (or omitted), multiple entities are created using `data` and `notes` and ignoring `uuid`. Default: `""`.
`uuid`	(character) A single UUID to assign to the entity. Default: `""`. With the default, Central will create and assign a UUID. This parameter is only used when creating a single entity (`label` non-empty) and ignored when creating multiple entities (`label` empty).
`notes`	(character) Metadata about the request which can be retrieved using the entity audit log. Default: `""`.
`data`	(list) A named list of Entity properties to create a single Entity, or a nested list with an array of Entity data to create multiple Entities. The nested lists representing individual entities must be valid as in they must contain a label, valid data for the respective entity properties, and can contain an optional UUID. See details and the ODK documentation for the exact format. Default: `list()`.
`url`	The ODK Central base URL without trailing slash. Default: `get_default_url`. Set default `url` through `ru_setup(url="...")`. See `vignette("Setup", package = "ruODK")`.
`un`	The ODK Central username (an email address). Default: `get_default_un`. Set default `un` through `ru_setup(un="...")`. See `vignette("Setup", package = "ruODK")`.
`pw`	The ODK Central password. Default: `get_default_pw`. Set default `pw` through `ru_setup(pw="...")`. See `vignette("Setup", package = "ruODK")`.
`retries`	The number of attempts to retrieve a web resource. This parameter is given to `RETRY(times = retries)`. Default: 3.
`odkc_version`	The ODK Central version as a semantic version string (year.minor.patch), e.g. "2023.5.1". The version is shown on ODK Central's version page `⁠/version.txt⁠`. Discard the "v". `ruODK` uses this parameter to adjust for breaking changes in ODK Central. Default: `get_default_odkc_version` or "2023.5.1" if unset. Set default `get_default_odkc_version` through `ru_setup(odkc_version="2023.5.1")`. See `vignette("Setup", package = "ruODK")`.
`orders`	(vector of character) Orders of datetime elements for lubridate. Default: `c("YmdHMS", "YmdHMSz", "Ymd HMS", "Ymd HMSz", "Ymd", "ymd")`.
`tz`	A timezone to convert dates and times to. Read `vignette("setup", package = "ruODK")` to learn how `ruODK`'s timezone can be set globally or per function.

Details

Creating a single Entity

For creating a single Entity, include

An optional uuid. If skipped, Central will create a UUID for the Entity.
The Entity label must be non-empty.
A named list data representing the Entity's fields. The value type of all properties is string.

uuid = "..." label = "John Doe" data = list("firstName" = "John", "age" = "22")

This translates to JSON

⁠{ "label": "John Doe", "data": { "firstName": "John", "age": "22" } }⁠

Creating multiple Entities

For creating multiple Entities in bulk, the request body takes an array entities containing a list of Entity objects as described above. The bulk entity version also takes a source property with a required name field and optional size, for example to capture the file name and size of a bulk upload source (in MB).

data=list(
    "entities" = c(
      list("label" = "Entity 1", "data" = list("field1" = "value1")),
      list("label" = "Entity 2", "data" = list("field1" = "value2"))
    ),
    "source" = list("name" = "file.csv", "size" = 100)
  )

This translates to JSON

⁠{ "entities": [...], "source": {"name": "file.csv", "size": 100} }⁠

You can provide notes to store the metadata about the request. The metadata is included in the POST request as header X-Action-Notes and can retrieved using Entity Audit Log.

Value

A nested list identical to the return value of entity_detail. See https://docs.getodk.org/central-api-entity-management/#creating-entities for the full schema. Top level list elements are renamed from ODK's camelCase to snake_case. Nested list elements have the original camelCase.
