[ZOPE] newbie question: getting title_or_id from calling document

Tue, 16 Oct 2001 12:53:15 +0100

I don't think I've expressed the problem clearly enough. It's not the
folder title we need, it's the title/ID of the document/method that
includes the header(via "dtml-var standard_header") .

The site has pages with a lot of common content that can be split into
the standard_header or standard_footer objects. The header has an HTML
block:
....
<head>
  <title><dtml-var title_or_id></title>
</head>
....

When the header is used by a page, I want the title to be that of the
page that includes it, not the name of the header file. So, if
index_html, with a title of "Homepage" has:
<dtml-var standard_header>

I want the resultant HTML to look like:
....
<head>
  <title>Homepage</title>
</head>
....

Not "header" or the title of the standard_header file.=20

I'm guessing that the same is going to apply to the footer, as it needs
to display the modification time.

I want to make the maintenance of the site easier by lumping together
the common parts. If I can't get the above to work, I'm assuming that
the only resort is to be long-winded (like my email) and forget about
using headers & footers and hardcode these bits into every page. There's
a lot of JavaScript too, which needs substitution for each page it's
used on. So it's not just the HTML title block.

Am I missing a technique/being thick?

Tanks for your time,
Simon.

If you want the title of the folder, then your calling-Document needs to
be
a method.  If there is no reason that your DTML-Doc has to be a doc,
this is
your solution.
DTML-docs are folderish and have their own properties that will be
inherited
by a method in the namepsace, overriding the folder properties.
This is why I have been told dont use DTML-Docs.

I am sure there is some DTML-magic workaround for your public_header
that
only calls the title of the objecttype('Folder').  But sometimes Zope
work-arounds are a replacement for mis-used object types and
architecture.
