cap-user-info

CDS plugin that adds user details on managed entities.

Install

npm install cap-user-info

Usage

The userinfo has the following properties by default that is added to the database

entity UserInfo {
        @UI.Hidden
    key ID         : UUID;

        @assert.unique: true  @title: 'Email Address'
        @Communication: {IsEmailAddress: true}
        Email      : String;

        GivenName  : String @title: 'Given Name';
        FamilyName : String @title: 'Family Name';
        FullName   : String = concat(
            GivenName, ' ', FamilyName
        );
}

Import it into your cds file.

using { UserTracked, UserInfo } from 'cap-user-info';

entity MyEntity : cuid, UserTracked {
  // your fields
}

The plugin auto-registers .after("CREATE" | "UPDATE") handlers on every application-service entity that includes the UserTracked aspect. Each handler UPSERTs the current user (req.user) into UserInfo. The associations _toCreatedUserInfo / _toModifiedUserInfo resolve via createdBy / modifiedBy.

The fields for createdBy and modifiedBy will automatically be shown as links with a quickview with the user details.

How it works

UserTracked extends managed, so consuming entities automatically inherit createdBy / modifiedBy (and the corresponding timestamps):

It will add a quickview to the createdBy and modifiedBy to show the user details. The details are stored from the req.user upon changes to the entity.

aspect UserTracked : managed { ... }

This means no extra managed declaration is required on the consuming entity — including UserTracked is enough.

Using the plugin for other purposes

Add a field to your entity and a association

using { UserTracked, UserInfo } from 'cap-user-info';

entity MyEntity : cuid, UserTracked {
  // The cds.on.insert is only to insert the userid automatically, otherwise handle it via code.
  Responsible: User @cds.on.insert: $user.id;,
  _toResponsibleUser: association to one UserInfo on _toResponsibleUser.ID = $self.Responsible
}

Then the quickview will automatically be active

Extending the quickview

You can extend the UserInfo to add more data into the quickview by adding to the fieldgroup in a cds file.

  // Change the quickview
extend cap.userinfo.UserInfo with
  @UI.FieldGroup: {Data: [
    // Leave the original properties
    {
      $Type: 'UI.DataField',
      Value: GivenName
    },
    {
      $Type: 'UI.DataField',
      Value: FamilyName
    },
    {
      $Type: 'UI.DataField',
      Value: Email
    },
    // your new field
    {
      $Type: 'UI.DataField',
      Value: Department
    }, 
  ]}

  //Change the 
  @UI.HeaderInfo     : {
    ImageUrl    : '',
    TypeImageUrl: 'sap-icon://employee',
    Title       : {
        Value: FullName,
    },
    TypeName    : '',
}
  {
    // your new field iin the entity
    Department : String @title                        : 'Department';
  }

Then register your event handler to populate the data. It's important this piece of code isn't added within your srv.init method. It needs to be in the root context.

cds.on("served", () => {
  const { db } = cds.services;
  const { UserInfo } = cds.entities("cap.userinfo");

  //Register the handler for the Upsert
  db.before("UPSERT", UserInfo, async (req) => {
    //Change the data
    req.data.Department = "Admin";
  });
});
