What I want is to have a document for every member of the directory members,
this document should have mirrors for some fields of members entries.
It's something like a wrapper so that users can modify their own directory
entries directly from that document, without having to go to directories.
The identifier of the document is the same as the identifier of the user, and
the document is created in the member's directory just after the first login.
In the schema of that type of content I have a field "surname" which should be
a mirror of "sn" field in members directory entries.
For that field I checked R/W ignore storage. The value of "Write: expression"
is:
python:util.setEntryField('members', 'sn', data[field.getFieldId()],
object.aq_parent.getId())
Where setEntryField is:
{{{
def setEntryField(self, dir_id, field_id, value, entry_id):
""" Update the field 'field_id' of the entry with 'entry_id' identifier
so that its value has 'value' as content.
"""
dtool = getToolByName(self, 'portal_directories')
dir = dtool[dir_id]
new_entry = {dir.id_field: entry_id,
field_id: value,
}
entry = dir._editEntry(new_entry)
}}}
The value of "Read: expression" is:
python:portal.portal_directories.members[context.aq_parent.getId()].sn
Where context.aq_parent.getId() is the identifier of the current document (i.e.
the identifier of a member)
This solution works fine for documents that have already been created, but it's
not good when documents are being created, as context is None.
I'm gonna try the advices of Yves. But, why the R/W expressions are called in
content creation? I though they would be used in view or edit modes only.
Thank you very much.

You haven't told us what you want to *do*.
What's context.aq_parent.getId() supposed to do?
