- Security permissions can now be declared as attribute metadata. |
| |
|
| |
That is, instead of doing declarations like this:: |
| |
|
| |
class Foo: |
| |
bar = binding.Require("Something", permissionNeeded=SomePerm) |
| |
|
| |
class AnElement(model.Element): |
| |
class someFeature(model.Attribute): |
| |
permissionNeeded = SomePerm |
| |
|
| |
you can (and should) now do them like this:: |
| |
|
| |
class Foo: |
| |
bar = binding.Require("Something", [SomePerm]) |
| |
|
| |
class AnElement(model.Element): |
| |
class someFeature(model.Attribute): |
| |
metadata = [SomePerm] |
| |
|
| |
or this:: |
| |
|
| |
class Foo: |
| |
binding.metadata(bar = [SomePerm]) |
| |
|
| |
class AnElement(model.Element): |
| |
|
| |
binding.metadata(someFeature = [SomePerm]) |
| |
|
| |
class someFeature(model.Attribute): |
| |
# ... |

It isn't necessary to enclose metadata in brackets, but it helps to |
| |
emphasize its annotational nature. Also note that e.g. 'web.bindResource()' |
| |
needs 'metadata' to be a keyword argument. |
| |
|
| |
- The 'permissionNeeded' attribute of 'model.Feature' and 'binding.Attribute' |
| |
objects is now DEPRECATED. See examples above for how to upgrade, and please |
| |
switch to using metadata as soon as practical. In addition the |
| |
'security.IGuardedDescriptor' interface has been removed, because it was |
| |
only used in connection with the 'permissionNeeded' attribute mechanism. |
