Re: [Zope] How to test for a user having a permission?

I know I can map methods to permissions and so have the Zope machinery take care of testing whether the user has permission to call a method, but say I want to decide whether to display an 'Edit' button on the page depending on whether the user has the appropriate permission for editing. How do I test for the user having this permission - is there some kind of hasPermission() method I can use? I could make an assumption about which roles have which permissions and call hasRole(), but that doesn't seem right to me* - I don't think my code should care about what roles the user has, only whether they have the required permission. Look in the embedded Online Help system -> API reference -> User
