I'm unable to sort a return set in the fetch function, becuase
the attribute I want to sort on is a custom attribute and not
supported.
It's basically a single selection so it SHOULD work, but it's not the
native single selection.
Is there any kind of operator to sort an existing array of content objects?
Or can somebody point me to the right place to start hacking? Where is the
code for the sort_by attribute functionality? Andy

Hello Andy The code for the sort_by parameter is in eZContentObjectTreeNode::createSortingSQLStrings (kernel/classes/ezcontentobjecttreenode.php). Which datatype are you using? If it's not publicly available, can you post the code from the functions sortKeyType and sortKey?

Hi Kristof,
The code for the sort_by parameter is in eZContentObjectTreeNode::createSortingSQLStrings (kernel/classes/ezcontentobjecttreenode.php).
Thanks for that.
Which datatype are you using? If it's not publicly available, can you post the code from the functions sortKeyType and sortKey?
Ah..
I think you caught me being stupid (and pointed me in the right direction).
The datatype in question is one I built myself (my first attempt at creating
a datatype actually) and is loosely based on the Fats Neutron verson of the country
datatype. I call it cfselection (content fed selection) and it's simply a rather vanilla
multiple selection, except that it takes its option list from the content tree. The data is
stored in a comma delimited string.
And I see that neither of the functions you've mentioned are even part of the
datatype which is probably a pretty good way towards an explanation and solution. May I assume that these functions are called from somewhere outside the datatype itself? Andy

Yes, they are. The result of the function sortKey is stored in the db ezcontentobject_attribute table in the field sort_key_text or sort_key_int, depending on what the sortKeyType function returns. eZContentObjectTreeNode::createSortingSQLStrings will know which field to use by calling sortKeyType.

Sorry, one more point of clarification:
This is sort_by 'attribute' that we're talking about, right?
Or maybe not? If these sort/key functions in the datatype are enough
to guarantee sorting, why does the documentation for sort_by attribute say
that only a hand full of datatypes are supported? Is the documentation out of date? (Please say yes)

Not every datatype in the kernel has implemented these functions.

But if I implement the functions in my datatype(s), then attribute sorting
will work correctly for them as well? Is that what you're telling me Kristof? Andy

If you implement the functions then sorting will work for your datatype, indeed. Good luck!

Thanks, Kristof.
Say, I sent you an e-mail the other day, using the address I found in
your sckcreatecopy extension. Did it not reach you? Andy

Kristof, sorry, another question:

[Kristof]Yes, they are. The result of the function sortKey is stored in the db
ezcontentobject_attribute table in the field sort_key_text or
sort_key_int, depending on what the sortKeyType function returns.
eZContentObjectTreeNode::createSortingSQLStrings will know which field to
use by calling sortKeyType.[/Kristof]
When are these sortKeys persisted to the DB?
When sorting works correctly, I'll have several thousand records to import. Do I need
to worry about the sort_key attributes with each record, or is that handled
by the core during normal object creation? Andy
