Hi devs,
The first proposal is about introducing two $xwiki.countDocuments
methods, one that accepts a simple hql query, and one that accepts a
parametrized query and a list of parameter values. These work like
searchDocuments, but instead of prefixing the query fragment with
'select doc.fullName from XWikiDocument as doc', it will prefix it
with
'select count(*) from XWikiDOcument as doc'.
This will allow to count documents without using a programming-
protected
query, and without retrieving all the documents and count the
results.
Such a method is needed for paging results, for example.
Sounds good to me.
Artem, how will this be done with the Query manager?
The second proposal is a temporary hack for
hiding documents. The
idea
is to add a new field in the XWikiDocument class, 'hidden', which
will
be automatically used in searchDocuments and countDocuments to
filter
out special documents. This is a workaround until we will be able to
tag
special documents or spaces, and will allow to create special
documents
needed for an application inside the main application's space,
instead
of the generic XWiki space. Such hidden pages won't appear in normal
search results, the index page or the navigation panel.
-0 (close to -1) till you explain what is wrong with the solution
below :)
This could also be implemented using a special Tag (like:
"xwiki:hidden" for example).
I was going to say: "In general I think we need the ability to add
generic metadata to a document.". however this already exists: it's
called Objects! :)
So I think instead of adding more and more fixed metadata we might
instead want to use Objects. Either reuse the existing Tag or
create a
new Visibility class/objects.
What are the cons of using Objects for this feature?
Using existing Tag object is not the best solution IMHO, since it
implies filtering out those "technical" tags everywhere we query tags.
