[Zope] Hotfix / 2.2.0 question
Greetings, fellow Zopers! A quick, non-urgent question for you all: After recently upgrading to 2.2.0, I noticed that under Control Panels/Products, I still had an entry for the security Hotfix from oh, so long ago, despite the fact that it's quite absent from my 2.2.0 Products directory. I just assumed it was safe to delete, so I did, but I'm wondering why it was there, and if, indeed, I should have deleted it. :) Thanks for your help, CJ ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

[Zope] Redirecting from Python?
Greetings!
I'm working on a Product, and I'd like to be able to do a RESPONSE.redirect()
from inside the Python code. What I had was basically this:
View the page . . .
This works fine, but rather than having that sitting out in DTML-land,
I figured I could put the conditions in the Python code and simplify
the if statement, so all I'd have to do is:
View the page . . .
The Python code I was hoping would accomplish this was:
def someConditions(self):
if (some number of conditions):
return 1
else:
self.REQUEST.RESPONSE.redirect('blahblahblah')
My problem is that the redirect just doesn't happen. I've had this
function return values and the like, so I know it's parsing my conditions
correctly, and I can even do a "return self.REQUEST.RESPONSE.redirect" and
have the function returned back into my page, but it won't actually
redirect.
Any ideas? Thanks in advance . . .

That should be pretty easy . . . Zope will let you add objects that have dots in the titles, so just put a method "index_html" in the root folder which has the following line: Then wherever there is "index.html", it will be displayed as the default document (go Acquisition!). Note that using a ".html" in files will make things a bit tricky sometimes when coding Python statements, because in python, "index.html" is looking for a property (or whatever) "html" in the object "index," which isn't going to exist, so you've got to be a bit cagey . . . -CJ ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Mirroring Zope sites
Hello, I'd like to be able to take a "snapshot" of a Zope site (probably using the recursive "wget") so that it can be served from Apache alone. I'm running into problems coping with files named "x_html" (most notably "index_html") . . . Apache serves up the files as plaintext, so you just get the HTML in your browser window. I've been messing around with srm.conf in my Apache configuration to try and accept "_html" as a valid extention for "text/html" files, but to no avail. Has anyone managed to get Apache to serve "_html" as text/html?

Re: [Zope] Costs of implementation
Well, I'd say that much of it relies on the kind of project you're doing, too. Sure, if all your DTML is doing is simple if/then statements, maybe a loop or two, it'll only take a few minutes to get used to the management interface itself. However, if you've got some seriously complicated things going on, it will be a lot more difficult. We've got an application framework being developed that relies very heavily on some extraordinarily tricky acquisition to get pages to render correctly. Everything is determined by the path you take to actually get to the page you want to look at, so a difference of one directory being present in the acquisition path can *drastically* alter how a page is displayed and functions (just adding the "admin" folder, for instance). Everything's automatically rendered. You basically never have to touch HTML again, because there's all these Widgets all over the place doing everything for you. Expecting someone to just jump into that kind of thing after becoming comfortable with the management interface would be insane. (Once you're into the Zen of the thing, though, it's wonderful!) If you're just putting together some relatively simple webapps, your timeline's probably all right. However, if you want a fully-functional ZCommerce site up, running, *secure,* and easily expandable, I'd say there's a lot more you've got to get through. :) Just my opinion, though. Perhaps I'm just slow. :) Happy Zoping! -CJ "J.
