Advocacy FAQ?
by srl 24 May '00

24 May '00

So, I was hanging out on IRC last night, and mentioned Zope to someone who's fairly active in the Python community. I ended up receiving a rant about how "bloated" and slow Zope is, and anecdotal evidence about Zope crashing Linux servers repeatedly. I know there was/is a memory leak that might be to blame in this case, but the fact remains: at least one person who might have been convinced that Zope is cool has been *seriously* turned off to it, for reasons of speed and memory hogging in a particular environment. Is there a Zope Advocacy FAQ somewhere I can use when people throw things like this at me? srl ----- Shane Renee Landrum slandrum<@>cs.smith.edu

python nigglettes
by Tom Smith 24 May '00

24 May '00

hi all, I'm currently experimenting with zope and noodling with python....can anyone give me an answer on these? Python is beautiful (nearly as beautiful as Prograph (but that's another story)). I'm a BIG fan of human readable code, I loved HyperCard and pathelogically refused to get my head past Perl. But there a few irritants that I really need to know why they're there. 1. ":" This smacks of geek...surely the interpreter could figure out if this wasn't there...couldn't it? Surely there's a workaround for someone like me. Isn't there? What if I "promised" never to write one-line functions, could I do without it then? 2."elif" Boy this is awkward, I though "elseif" was bad but "elif" !! Can I use/implement alternatives "elseif" would be a start "else if" would be better...more natural. I love the fact that with Python it's OK (nay encouraged) to document code. I can live with the "__whatever__" methods but ":" and "elif" are so ugly that as I'm showing someone how cool Python is, I get embarrased...and make excuses....along the lines of...."yes, yes, I know, but look how easy it is to create a subclass of Animal..." cheers tom

Erm.. well, since this is in the standard_html_header, it is included at the start of all DTML documents, unless you remove the  that is put in by default when you create a DTML document or method. So, technically, no, it does not 'stay', but is generated for each page. This, however, is an advantage, since it allows the index at the top, and information at the side, to be updated simply, instead of having to deal with complex frames targets stuff. > > Thanks for any help you can provide. Not a problem. Also, I didn't document this entirely in my first post, neglecting to mention a couple of things that would be aparent to experienced Zopistas, but not to newbies. In the side-bar, there is the option to include extra text on a per-folder AND per-document basis. > >> <hr size="1" width="80%"> > >> <dtml-var side_bar> > >> <hr size="1" width="80%"> > >> <dtml-if sub_bar> > >> <dtml-var "_[sub_bar]"> > >> </dtml-if> This means that 'side_bar' will be rendered at this point, and if there is an attributed of 'sub_bar', the object it names will also be rendered. > > Regards, > Luis. > -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Zope Advocacy FAQ redux
by srl 23 May '00

23 May '00

So, after poking around on Zope.org for awhile, I haven't found an Advocacy FAQ. Have I missed something? I hope not, because I started one. This is a very rough draft, hacked together from memory. As such, it's quite likely inaccurate on some particulars, and most certainly incomplete. I'll be working on it more over the next few days. If you've got comments or additions, please email me and I'll credit you. To make the Advocay FAQ more complete, I'd love to hear: if you're using Zope in a situation where you had to get management buy-in, what convinced them? What objections did they have, and how did you counter those objections? http://www.zope.org/Members/srl/advocacy_faq PS. this is my first try at any sort of public document for an open-source project. I'd love to hear criticism in email or onlist. srl ----- Shane Renee Landrum slandrum<@>cs.smith.edu

RE: [Zope] FTP

When I try this I get an unauthorized user error. Can you give an example of how to connect to port 8021 with a simple ftp program. -----Original Message----- From: Rik Hoekstra [mailto:rik.hoekstra@inghist.nl] Sent: Tuesday, May 23, 2000 7:37 AM To: David Shen Cc: zope(a)zope.org Subject: Re: [Zope] FTP > David Shen wrote: > > Hello, > Can Zope system be accessed by FTP? If yes, how to do so? Yes. Assuming you have a standard Zope installation and you've not tampered with the ftp settings of ZServer (you'd know about ftp then wouldn't you). THe ZServer ftp is running under the (non default) 8021 port. You should point your ftp client to ftp://yoursite:8021/ That's it.

Passing multi-line field into SQL
by Tony Mann 23 May '00

23 May '00

We have a form with a textarea on it, that can contain line breaks. When we try to pass it into an SQL statement <dtml-sqlvar textarea_value type=string> we get a parsing error, due to the embedded newlines. We would like to convert the newlines to "<BR>" strings. Does anyone have an easy solution for doing this? We have tried using split/dtml-in and split/join in the SQL, but getting these statements past the SQL parser, with all the quotes, has proven to be tricky. ..tony..

Any idea why or what >is _vti_bin? > Yes, it is (one of the) the dreaded Frontpage extension(s). Why you would get it and someone else wouldn't ... I don't know. Perhaps you have MS products that use FP extensions (Frontpage, Interdev, whatever) installed? Rik

<dtml-in REQUEST>

I remember I saw somewhere about it. but I couldn't search it out again. Can anyone tell me the correct way to do things like following? <dtml-in REQUEST> <dtlm-var "key">:<dtml-var "value"> </dtml> I want to check the indivial item inside the REQUEST one time at a time. but if I do <dtml-in REQUEST> I think it is not actually a list so that it is usable by dtml-in tag Kwan
