The trail object

The trail object is a plain object with the following attributes:

  • when: MANDATORY - A timestamp. When writing, it can be a Javascript date, a string in the RFC3339 (basically ISO8601) format or a luxon DateTime. In all case, the timestamp is converted to UTC timezone. When reading, a UTC luxon DateTime will be returned.
  • who: MANDATORY - The actor who performed the action. See below for the description of its type.
  • what: MANDATORY - The action that was performed. See below for the description of its type.
  • subject: MANDATORY - The subject the action was performed on. See below for the description of its type.
  • where: A optional object describing the location where the action was performed.
  • why: A optional object describing the reason why the action was performed.
  • meta: Additional metadata for this trail.

The who, what and subject attributes are objects containing at least the id string attribute. When creating or updating a record, you can specify just a string. It will be automatically converted to a object containing only the id attribute.

API

async TrailsManager.insert(trail)

Inserts a new trail in the database.

Returns the newly trail id.

async TrailsManager.get(id)

Fetches a trail from the database.

Returns the requested trail or null.

async TrailsManager.update(id, trail)

Replaces a trail in the database.

Note that partial updates are not supported, which means that the record will be completed replaced.

Returns true if the record was found and updated, false otherwise.

async TrailsManager.delete(id)

Deletes a trail from the database.

Returns true if the record was found and deleted, false otherwise.

async TrailsManager.search({from, to, who, what, subject, page, pageSize, sort, exactMatch, caseInsensitive})

Searchs for trails in the database.

The from and to attributes follow the same rule of the when trail attributes and are inclusive.

The who, what and subject attributes must be string and can be used to search inside the id attributes of the respective trail attributes. You can use exactMatch (default to false) to match only trails which id is exactly the searched value. You can use caseInsensitive (default to false) to ignore case when matching values.

The page and pageSize attributes can be used to control pagination. They must be positive numbers. The default pageSize is 25.

To sort results, use the sort attribute. It supports sorting by the id, when, who, what and subject attributes. The default sort direction is ascending, but it can be reversed by prepending a dash. (i.e: -who). The default value is -when.

Returns an array of found trail objects.

async TrailsManager.enumerate({from, to, type, page, pageSize, desc})

Searchs for distinct ids in the database.

The from and to attributes follow the same rule of the when trail attributes and are inclusive.

The type must be one of the following values: who, what or subject.

The page and pageSize attributes can be used to control pagination. They must be positive numbers. The default pageSize is 25.

The desc can be set to true to sort results by descending order.

Returns an array of found id (depending on the type attribute), ordered alphabetically.
