Add exposed filter for user roles

Question

In Ubercart, the uc_order view (admin/structure/views/view/uc_orders) uses exposed filters for status and order ID.

I can add another filter, for example username, email and so on by clicking on Add filter criteria and selecting the criteria (user:username, user:email).

I need to add a filter to filter orders by the roles assigned to customers. There is no option such as user:roles in the filter criteria list to select.

How can I achieve this?

Answer 1

By configuring the Access: section on the Page settings, we can manage Page: Access restrictions.

Choose the Roles and assign the required user role.

Answer 2

The solution is to open "advanced" section, add new "relationship" marked as "order:customer". After this new options in "add filter" will be available. So click at "add filter" and select "user:role" and set it as "exposed to users".
