session-attributes

This sample is developed in response to the following questions on the CUBA support forum:

1. https://www.cuba-platform.com/support/topic/company-selector-in-main-window
2. https://www.cuba-platform.com/discuss/t/extend-user-of-cuba-platform-with-new-attribute-manager/3213

Data Model

The application contains the BusinessUser enity, that refers to the system User, which comes along with CUBA and used for security and auth purposes. A business user also encapsulates additional information that is used by the business logic of your CUBA application. In this sample it has an additional reference to the Company enity.

Functional Overview

The application retrieves information about the related business user for a logged-in user and adds it into the session attribures, so it can be taken from it at any time. Find the implementation of this part here, it handles the UserLoggedInEvent event and add the required session attribute.

In the main screen implementation contains an example of how you can access this session attribute from the controller. It sets a lookup field (in the top right corner) to a value, that is saved in the business user coming from session attributes.
