Re: [Zope3-Users] Variables in reStructuredText
Just as an idea: use the python string modul for substitution.
Write in ReST:
.. figure:: path/to/image
$title
or
${caption}
and in your python code:
theTitle = myPhoto.getTitle()
theCaption = myPhoto.getCaption()
theText = GetTheRestructuredTextFromMyData(...)
theText = string.Template(theText).safe_substitute(theTitle, theCaption)

We have tried ZAlchmey, and SQLOs, but we find them both a bit limiting and simultaneous complex to get them to work they way we wanted. In general when one develops and RDBMS application of any size, the database structure can get very complex. In order to integrate them into Zope 3 just right, it's best to manually code the containers and objects. We have been able to simplify the process quite a bit and we are very happy with it. It's amazing scalable.If you do decide to go this way, I would be glad to share our RBDMS package and procedures. We've developed some guidelines to improve development.

Zope 3 has a bug in the database adapters that requires having to use global utilities (etc/overrides.zcml). It is otherwise stable.

The new approach is to skin the ZMI to match your own design scheme. The staff who uses our old management applications in UNIX and PHP loves the new Zope 3 stuff we've done.

We use SQL although I do wish that SQL integration was stronger. The structure of Zope is excellent for scalability. You'll pay up front a little, but the simplicity and versatility is really great. We've basically only found 2 platforms that scaled well, J2EE and Zope 3. Zope 3 is vastly better in nearly every way in my opinion, except perhaps documentation. The documentation is very weak, but it is a young platform. The content view model of Zope 3 and the clean API's is wonderful. The pla
