Developing an Application

 

OutSystems

Create a Custom Role

You can restrict or allow end-users access to specific screens and operations of your application using your own custom Roles. For example, you can create a back-office Role, set the Role in your application's back-office screens, and grant this Role only to those end-users who are entitled to access the back-office screens.

To create a custom Role, do the following:

  1. Go to the Logic tab;
  2. Right-click the Roles folder and select the Add Role option;
  3. Set the Name of your Role and the remaining information.

Once a new Role is created, you can assign it to end-users through the Users application or you can create logic in your application to manage the access.

Use the Role in your Application’s Logic

When you define a new Role in your module, OutSystems provides a set of System Actions, built-in functions, and exceptions necessary to use the Role in your logic.

Role Actions

For each Role in your module, OutSystems provides the following Actions:

  • Check<Role name>Role: Checks whether a specific end-user has been granted access to a specific role.
  • Grant<Role name>Role: Provides access for a specific end-user to a specific role. This action is not available for the System Roles Anonymous and Registered.
  • Revoke<Role name>Role: denies access for a specific end-user to a specific role. This action is not available for the System Roles Roles Anonymous and Registered.

Role Actions are available in the Logic tab, within the Roles folder, under the corresponding Role, and can simply be dropped into your action flow.

Role Functions

To check end-user Roles in your expressions, OutSystems provides the following built-in function:

  • Check<Role name>Role

This function is available in the Scope Tree of the Expression Editor, under the Roles folder. 

Role Exceptions

For each Role in your module, OutSystems creates the following Exception:

  • Not <Role Name>

This Exception is raised when a user tries to access an element, for example a Screen, that requires a specific Role and the user has not been granted with that Role.
