[Zope] images in directories

[Danny William Adair]

I have a similar situation where I find myself way down in the tree
structure and have to go up to a certain point and down again. Leaving "bad
structuring" aside (actually its well structured in many other respects),
all I could think of to get a hold of these objects was a whole bunch of
nested "with" statements. They suck.

Now what's with your PathHandler product? How would an appropriate method
look like? I was thinking of a "walk2object" method rather than
"showImage"... see I don't want to start at "/", I want to start whereever I
like at that moment and still take the "/"-separated path info to "walk" to
my object.

I think this has more to do with elegance than with lazyness. (tho these two
know each other very well ;-) )

tia,
Danny

...worked for me all the way back to 2.1.4 ;-)

Anyway, if you're _really_ lazy, write an external method something
alogn the lines of:

def showImage(self,path):
	return self.restrictedTraverse(path)(self,self.REQUEST)


...then, in your dtml, you can do:

<dtml-var "showImage('/images/image.gif')">

This is all totally untested of course ;-)

I've often wondered why this isn't built into DTML so that you could do:

<dtml-var /folder/myobject>

obviously, you wouldn't be able to do this with stuf inside " " ;-)

cheers,

Chris
