If you are interested in seeing what happened to an event, then you should look at this video. 

If you are interested in seeing what happened to medication, then you should look at this video.

If you are interested in looking at changes to Careplans you should click on the  button on the Careplan tab of the relevant Client form.

If you are interested in what happened to tasks you can look at either the Careplan history or (for more detail) at the above video for medication (the techniques there can also be used for tasks).


If you want to know about other types of data - carry on!


Many of the database collections are audited, so you can see how and when changes happened.


The easiest way to do that is by making a small change to the URL when viewing the using the record you are interested in, by changing the final /edit to something else.  The full list of URLs available is shown below.


Show all updates

/<model>/<id>/changes 

/<model>/<view>/<id>/changes 

This displays a screen showing all the audited changes to a document.  Each line is a link to a representation (normally JSON) of the state of the document after the update.

Each line shows elements that may include:

  • time of the audited event (in UTC - which is what techies call GMT)
  • <changes> area, which shows the changes that were made if you hover the mouse over it.  There is an example in the screenshot above.  The format is the name of the attribute that is changed and, in the simplest case, the old value followed by the new value.  Arrays and large text fields are more complicated - see here for a playground - we use the JSON output format.
  • a description of the operation (created / modified / deleted)
  • a summary of top level modified fields
  • the name of the user


Show all audited events

/<model>/<id>/history 

/<model>/<view>/<id>/history 

This displays a screen showing all the audited events involving a document - which is always a superset of the /changes URLs above.  This includes people accessing the records.


Show the record at a point in time

/<model>/<id>/version/<version>

/<model>/<view>/<id>/version/<version>

This recreates the value of the specified version of the item and displays it in JSON format.  It is used by the /history and /changes URL formats above.  Sensitive data such as username and password hash are removed.
