Customization of PermissionDenied

[Massimo Bono]

Hi,

I wonder if there is a way to customize the error PermissionDenied (specifically its error message), thrown whenever the autheticated user has invalid permissions to gain access to the given function. Currently I am using hte permission_required decorator.

Just for completeness sake, what I am trying to achieve is to add to the error message the list of missing permissions the user do not have.

Thanks

Hey @Koldar,
You can write auth decorators with just a few lines:

def permission_required(perm):
    def check_perms(user):
        if isinstance(perm, str):
            perms = (perm,)
        else:
            perms = perm
        return user.has_perms(perms)

    return user_passes_test(check_perms, exc=Exception("you shall not pass!"))

..and easier for @login_required:

login_required = user_passes_test(
    lambda u: u.is_authenticated,
    exc=Exception("you shall not pass!"),
)
