Hi there. In our application we implemented a page that utilizes the default ABP app services IIdentityUserAppService and IIdentityRoleAppService to list users and roles. Therefore, this page requires the permissions "AbpIdentity.Users" and "AbpIdentity.Roles" to work correctly.
So, to avoid unexpected permission errors when setting up the roles for our application, we need to implement a proper permission dependency when defining our own permissions, as explained in the documentation here and here.
With this in mind, we added the dependencies to our permission definition:
public class MyModulePermissionDefinitionProvider : PermissionDefinitionProvider
{
public override void Define(IPermissionDefinitionContext context)
{
var myModuleGroupDefinition = context.AddGroup(MyModulePermissions.GroupName, L("Permission:MyModule"));
var myModuleGroup = myModuleGroupDefinition.AddPermission(MyModulePermissions.Home, L("Permission:MyModule:Home"), MultiTenancySides.Tenant);
var reportsPermissions = myModuleGroup.AddChild(MyModulePermissions.Reports.Default, L("Permission:MyModule:Reports"), MultiTenancySides.Tenant);
reportsPermissions.AddChild(MyModulePermissions.Reports.ReportManagement, L("Permission:MyModule:Reports:ReportManagement"), MultiTenancySides.Tenant)
.RequirePermissions("AbpIdentity.Users", "AbpIdentity.Roles"); // this is what we added
}
private static LocalizableString L(string name)
{
return LocalizableString.Create<MyModuleResource>(name);
}
}
What I expected to happen: for my custom permission MyModulePermissions.Reports.ReportManagement to always require the permissions "AbpIdentity.Users" and "AbpIdentity.Roles", in a way that they should be automatically selected in the permissions pop-up when my custom permission is selected, or at least give me an error and not allow me to save until the dependent permissions are also selected, making the permission dependencies clear and mandatory when setting up the permissions for users or roles.
What actually happens: in the permissions pop-up I can select my custom permission MyModulePermissions.Reports.ReportManagement and save without any action or feedback that my custom permission depends on other permissions. From my tests, all RequirePermissions does is consider my custom permission not granted unless the other required permissions are also granted, which is very confusing since my menu entry won't appear for the user even when they have that permission granted (but not its dependencies).
Am I missing something or is this the expected behavior? If so, is there a way to implement permission dependencies in the way I described?
Thanks!

The behavior you are seeing is the expected and intended design of ABP's permission dependency system. When you use
.RequirePermissions("AbpIdentity.Users", "AbpIdentity.Roles")in your permission definition, ABP will only consider your custom permission as "granted" if both the permission itself and all required permissions are granted to the user. However, this dependency is enforced at runtime (authorization check), not in the UI.The ABP Permission Management UI (the permissions pop-up/modal) does not automatically select or enforce dependent permissions when you select a permission that has dependencies. It also does not prevent saving if dependencies are not met. The dependency is only checked when the permission is used (e.g., when accessing a page or API that requires it).
There is currently no built-in way in ABP to make the permission management UI automatically select, enforce, or visually indicate permission dependencies. The UI will allow you to grant a permission without its dependencies, but at runtime, the permission will not be effective unless all dependencies are also granted.
If you want the UI to enforce or visually indicate permission dependencies, you would need to customize the Permission Management UI. This would involve overriding the relevant components/pages to add logic that checks for dependencies and updates the UI accordingly.
In summary:
.RequirePermissionsonly affects runtime authorization, not the UI.- There is no built-in mechanism to enforce or display permission dependencies in the permission management UI.
- Customization of the UI is required for the behavior you described.
