This is not a question, I think it's more a request for comment.
Problem: I have the following structure of folders. The top folder has
the global standard_html_header and acquisition has it, that it
is usable in all the subfolders.
Now I have a small modification in my headers from SubFolder1 downwards.
Well, there are many ways to cope with that problem, I want to do it
that ways: I want to integrate the old standard_html_header into the
new one I define in SubFolder1. Ok, that can look like this:
<load old standard_html_header>
<my addtional code>
The problem I have to solve now, is to load the old standard_html_header.
Solution: I will give you all my tries, just for fun :-))
:-( First try: <dtml-var standard_html_header>
The easy way certainly doesn't work. It gives a nice error:
"SystemError: infinite recursion in document template"
And it shows you, that Zope really is quick. It does the
infinite loop in less than 30 seconds :-)))
:-( Second try: <dtml-var "PARENTS.standard_html_header">
Well, this gives me the right object, but it isn't rendered. As
I reviewed the list archive, I found out, that this seems to be
normal. Maybe somebody can explain why, if he/she has
:-( Third try: <dtml-var "PARENTS.standard_html_header(_.None,_)">
Wow, it works! But, as the smiley implies, it has its disadvantages:
Using it in SubFolder2 gives again an infinite recursion.
Find out for yourselves, why ;-))
:-) Fourth try: <dtml-var "PARENTS[-1].standard_html_header(_.None,_)">
or: <dtml-var "FolderName.standard_html_header(_.None,_)">
if you want to use the method of a subfolder.
That seems to be the right way. Any comments?
After the second try (my first serious one ;-) I tried the following:
but this has the disadvantage, that standard_html_header uses the namespace
of PARENTS[-1] to display things like id or title.
Maybe this should go into the FAQ?
