In fact, I find it too hard to code something using DTML, that's why I'd like to use good old python and to keep only variable substitution in my HTML (dtml-var, or maybe just &dtml-my_variable; which is an easier to use form of it, or maybe replace it with @my_var@ or smth like that, which I would find even easier!) I'd like to be able to delimit blocks in an HTML file and to use these blocks from a python program, the goal is to completely separate the code from the design (HTML). With DTML, the code and the design are mixed. it would look like this: def index_html(_): "Display a list of items taken from the products database" if not check_password(): return bad_password_page query_result = my_zsql_query(_) if not query_result: return my_template.no_result result = ReturnStream() result.add( my_template.header ) for line in query.result: result.add( my_template.one_line, line ) result.add( my_template.footer ) and my_template would be an HTML file with <dtml-block> tags that delimit the header, one_line and footer blocks. The one_line block would use some variables defined in the line dictionary; for example: <dtml-block one_line> <tr><td>@item@</td><td>@quantity@</td><td>@price@</td></tr> </dtml-block> The DTMLTemplate and PythonMethods products seem to provide this kind of separation between code and design, but I did not manage to get them working properly together: DTMLTemplate: when I display a block (using <dtml-var "my_template.my_block">), the HTML tags in my_block appear quoted, should I use a fmt="html" or something like that to avoid the quoting? PythonMethods: how can I access Zope objects from my method? Typically I'd like to call a template block from my method, but just using my_template.my_block doesn't work. As you can see, I'm not a Zope guru, but I'm willing to learn! I believe that Zope and PTK have a big role to play in the current portal and application servers war... ready to use portal-in-a-box products cost around $100,000... so for that price you can use zope and afford more consulting and coding services! BTW, currently I'm experiencing a problem: no images (icons, ZopeButton etc..) appear on my management pages, images stored in the ZODB are ok though. any idea where are those images like http://localhost:8080/p_/ZopeButton ? Thanks for your time!
