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 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:
@item@@quantity@@price@
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 ), 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!
