Updating Data

In order to update data, you can reference an existing subject by using its _id or, for any predicate marked as unique as a two-tuple, i.e. ["_user/username", "jdoe"]. Predicates that you wish to update should be included as key-value pairs.

When referencing an existing subject, "_action": "update" is inferred. Note: When updating and upserting, you can use nested transactions.

Update using a two-tuple with a unique predicate. i.e. person/handle and relevant object:

[
  {
    "_id": ["person/handle", "jdoe"],
    "fullName": "Jane Doe Updated"
  }
]

Update using subject id:

[
  {
    "_id": 351843720888321,
    "fullName": "Jane Doe Updated By Numeric _id"
  }
]

Update Jane Doe's Handle

Write a transaction!

Using the above transaction examples, write a transaction updating Jane Doe's handle to "janieD".
