[daisy] [JIRA] Commented: (DSY-502) Hiding linknodes from the navigation tree.

[Bruno Dumon (JIRA)]

    [ http://issues.cocoondev.org//browse/DSY-502?page=comments#action_13242 ] 

Bruno Dumon commented on DSY-502:
---------------------------------

First implementation is now in SVN trunk.

It uses the following new attributes on the link node: inheritAclDocId, inheritAclBranch, inheritAclLanguage

The inheritAclDocId can have the value "this" to refer to the containing navigation document.

I'm open to better name proposals.

> Navigation documents's are proper documents in Daisy that are used to build up navigation-tree's.
> Being documents they comply to the normal ACL rules, handing out read-write access to them.
>   * meaning: depending on the outcome of the ACL you might not be able to 'access' and/or 'change' the navigation document on the repository
>    Important though is that ACL is not controlling if a user can actually USE that navigation (this allows people to be able to 'use' the navigation in the side, and thus 'see and interact with its in page-representation' while not being able to actually access (read) the actual navigation document!)
> Note thought that in producing the navigation tree representation for a certain user there i*s* some additional ACL filtering going on: the navigation links pointing to document nodes on which the user does not have access will be filtered out.
> This way of working however makes it a bit hard to be able to remove link-nodes from the user's view of the navigation tree.  Link-nodes are not associated to documents and therefore have no matching ACL rule that could ever point out that the link should be hidden for the current user.
> I would therefore propose to allow link-Nodes to specify from which Daisy document they want to inherit the ACL rule to be applied on them. This could be expressed through a inheritACLFrom attribute on the link-node.  As a scpecial value for this attribute we could allow "ContextDoc()" thus pointing to the document containing the navigation-part that is holding the link-node itself.  If the attribute is not set, behaviour should be as today: no filtering.
> By extension we might consider putting such kind of attribute also on import-nodes. This would allow people to split up the navigation in certain parts to be imported, and easily use the ACL rules on those different navigation-documents to affect the effective import into the nav-tree-representation in a way similar as described for the linknodes...
