You should probably try to set the __parent__ of the adapter to the __parent__
of the adapted object (or to the object itself)

I have no idea how to get the absolute url of an adapted object, or even if
its possible. If you can, please bear with me and I'll try to explain myself
clearly.
Consider this example (simple object and adapter):
class IStudent:
"""Simple student object"""
studentNumber = StudentNumber(
title = _("Student Number"),
description = _("""The student's ID number."""),
required = True)
class IStudentPhoto:
"""Adapts Student to IImage"""
The unit tests for my class and adapter passes fine, so I know that doing
something like the following works...
photo = StudentPhoto(Student("123456789"))
My problem is that I want to display the photo in a browser but can't figure
out how. I created a browser view helper in python, and it seems to work for
the most part:
class StudentDetails:
"""Helper to return a student photo."""
def getPhoto(self):
student = self.context
return StudentPhoto(student)
In my page template, I can see that the IImage object is being created
correctly..
<div tal:define="photo view/getPhoto">
<span tal:content="photo">#</span>
</div>
gives me <zope.app.file.image.Image object at 0xb75c6c6c>. But to turn this
object into a URL so that I can put it in an <img> tag is beyond me. When I
try to do an @@absolute_url on the photo object I get the error saying
there's not enough context.
Am I going about this the wrong way? Is there some other thing I need to be
doing in order for there to be enough context?
Thanks for any help,
Greg
