Nor clearer - your blog is quite clear - but more elementary, for us novices. I'm very attracted to your idea of one Python call that takes care of returning all the data that the page needs. But I'm not sure just what you are including in the term "data": * I assume you include data retrieved from (and updated in) an underlying relational database. * Does "data" also include parameters (or arguments, or query string variables, or whatever you call them) passed from one HTML page to the next? This parameter-passing is what I seem to be having trouble with. How does that script get the info it needs from the previous page? In my example, when my "personform.htm" updates a record and then re-calls itself, how does it get the person_id identifying the record it's supposed to display the second time around? I have a feeling that there's some point I'm just not getting here, but that I'm too new to this to figure out what it is. - Ken _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
