modelbinders

We know authorization stuff is a cross cutting concern, and we do anything we could to avoid merge business logic in our views.

But I still not found an elegant way to filter UI components (e.g. widgets, form elements, tables, etc) using the current user roles without contaminate the view with business logic. same applies for model binding.

Example

Form: Product Creation

Fields:

Name
Price
Discount

Roles:

Role Administrator
- Is allowed to see and modify the Name field
- Is allowed to see and modify the Price field
- Is allowed to see and modify the Discount
Role Administrator assistant
- Is allowed to see and modify the Name
- Is allowed to see and modify the Price

Fields shown in each role are different, and model binding needs to ignore the discount field for 'Administrator assistant' role.

How would you do it?
