AGX neither a method nor a callable

[bad_my84]

Hi all,

I'm developing my own product in archgenxml but I'm running into problems with a default_method.
I have 2 simple classes: 'Medewerker' and 'Afspraken'. 'Afspraken' is contained in 'Medewerker' (composition).
In agreement there is a StringField (called 'medewerker') which I want to give the default of 'Medewerker'-title.

To the 'medewerker' StringField I added the tagged value 'default_method: findParentTitle'
In Afspraken.py I added the following code to the 'code-section after-local-schema':

    security.declarePublic('findParentTitle')
    def findParentTitle(self):
        """
        Populates the field with the title of its parent.
        """
        return self.aq_parent.getTitle()

What am I missing here?

Thanks in advance!

Try:
    return self.aq_parent.Title()

The title and description fields are exceptions to the rule that the
generated 'getter' of the field is 'get' plus the capitalized
fieldname.  The getters of these two fields are Title and Description.

I would expect a different error message though, so maybe this is
unrelated.

I already tried Title() and 'get' plus capitalized fieldname.
Does it have something to do with security?

[bad_my84]

Found part of the problem... me! (shame shame)

If I added the method in the right place, inside the class that is, it
wouldn't have had the error.
Now I can get the values from all fields from it's parent, except the title.
With .Title() there is no value and with .getTitle() there's an error?

getTitle does not exist so I would expect an attribute error.  Title
*should* work.

The names Title and Description do not have the 'get' in front of them
as the Dublin Core metadata standard expects to be able to ask for
Title and Description.  I don't know the details, but this probably
helps when other systems need to interact with Plone, presenting a
familiar interface.

That sais, try self.aq_inner.aq_parent.Title().  Depending on the
exact code path the aq_parent might not be what you expect and the
extra aq_inner should help there.

In your browser you can also go to <url of parent>/Title and see what
that returns.  I wonder if that perhaps returns nothing in your case.

I got it!
It was getting its own title and not that of it's parent, found this out
by trying to get the id. It returned the name of the contenttype.
So how do i get the title of the parent and not of itself?

Thanks in advance!

Thnx, the UID I get is correct, but how do I use the catalog to get the
title?
This is what I got so far, but it gives the error: LazyMap instance has
no attribute 'Title':
security.declarePublic('findParentTitle')
def findParentTitle(self):
        """
        Return the parents title
        """
        catalog = getToolByName(self, 'portal_catalog')
        uid = self.aq_inner.aq_parent.UID()
        brain = catalog(UID=uid)
        result = brain.Title()
        return results
