Is there a tool for pretty-formatting/indenting DTML code?
by Chris Beaumont 25 Oct '00

25 Oct '00

I've been working with Zope for a bit now and I love it. However, a few of the tools I'm used to having with other scripting tools are missing in the Zope realm.. One thing I would very much like to have is a script that could go through a long DTML document and pretty-format the code, not unlike the way I use BBEdit's formatting command on my Mac for HTML. Does such an animal exist, on any platform, or should I just try to adapt something I already have? I don't want to have to reinvent the wheel so to speak.. The big reason I need this is for indenting.. It makes the code much more readable and I have found myself spending a lot of time doing this by hand.. it just gets tedious.. Thank you..

RE: [Zope] OT:NT and rebooting (was:How many houres do I need to manage a Zope) site?
by Farrell, Troy 25 Oct '00

My 2 ZoNT (Zope on NT workstation) boxen haven't needed rebooting yet. They sit mostly idle with occasional light loads. They are P100/32MB/1.2GB old(er than dirt) Industrial Computer Supply boxes. You know, 19" rack mount 4U units. Good, solid, slow hardware. They survive NT rather well. One is running 2 instances of Zope (one for dev) and has been for 15 days since last reboot. I will be looking for at least a 6 month uptime. They serve a departmental intranet application that I am writing. It's on NT because I need to use ODBC to get to a local MS Access Database. Bummer.

TinyTablePlus: Problems with quotation marks

I have problems using Shane Hathaway's TinyTablePlus product. Maybe you can help me. ************************************************************************** My TinyTablePlus instance: ************************************************************************** ID: Items Title: Items on Navigation Bar Columns: Position ShowItem Caption UseImage Image Service URL Data: "1", "yes", "HOME", "yes", "Home", "Home", "/Main" "2", "yes", "News", "yes", "News", "News", "/News" "3", "yes", "Discussion", "no", "", "Discussion", "/Discussion" -------------------------------------------------------------------------- ************************************************************************** My code: (I want to create a configuration page for a navigation bar, which will have to change a table's rows depending on the contents of some form elements) ************************************************************************** <dtml-let Position='1' Caption='test'> <dtml-in Items sort=Position> <dtml-call "Items.setRow(Position=Position,Caption=newCaption)"> </dtml-in> -------------------------------------------------------------------------- ************************************************************************** My problem: ************************************************************************** Data afterwards: "1", NULL, "test", NULL, NULL, NULL, NULL "1", "yes", "HOME", "yes", "Home", "Home", "/Main" "2", "yes", "News", "yes", "News", "News", "/News" "3", "yes", "Discussion", "no", "", "Discussion", "/Discussion" -------------------------------------------------------------------------- Shouldn't setRow recognize the existing row and change that one? I can't see what I am doing wrong here. Does it have anything to do with the double quotation marks in the data? tia, Danny

Calling form elements by name

How can I render a REQUEST variable in DTML if I have its id as a string? I would like to construct its name as a string and then call the REQUEST variable by its name. (Meaning I will have to make sure such an object exists) tia, CU+Prost, Danny

Python product - inherittance
by Petr Knapek 25 Oct '00

25 Oct '00

Hi Zopists, I have a problem with inherittance of my publishable python classes. I created in python classA and classB(classA) classA has functionA and classB has functionB. In __init__.py of my product I register only classB. My problem is that it is not possible to call functionA of an instance of classB. There is 'Error Type: AttributeError'. Does anybody know where the problem is? I use Zope 2.1.6 Thanks, Petr -- Petr Knápek NEXTRA Czech Republic, s.r.o., Hlinky 114, 603 00 Brno, Czech Republic e-mail: knapek(a)nextra.cz

AW: [Zope] dtml-var owner? author? editor?
by Patrick Koetter 25 Oct '00

25 Oct '00

> > I want to include the owner (from acl_users) of a page in my > HTML-output. > > <dtml-var "AUTHENTICATED_USER.getUserName()"> > is what you want Not exactly. This only returns the AUTHENTICATED_USER, or am I wrong? What I want is: 'Anonymous User' surfs to my site. She surfs trough the HTML output generated by zope, while zope not only tells her the content provided, but also the Name of the Zope-owner of the document (e.g patrick is owner of index_html --> that info is also displayed to the anonymous user) Thanks for more help, p@

Re: [Zope-dev] Task, Job or Operation?
by Jimmie Houchin 25 Oct '00

25 Oct '00

Just a few comments to throw into the naming convention. Any name chosen will require educating the user as to it's definition. Some names are already defined in other spaces. Some of which are heavily overloaded. There is also discussion as to the accuracy of various names in the context of the usage within Zope. It is apparent the choice isn't clear and easy. As Michel has posted that a vote will occur in the near future a determination will be made. Currently one of the terms in usage is External Methods. From my understanding of the future direction of the Python Methods (restricted and unrestricted) the term External will not be accurate as the code will be within the ZODB and the differentiation will be in the capability of the method. Due to this I think the usage of External not be included in the name. Likewise Internal. Regarding Safe and Power. I have no major problems with Safe, however I thing Power brings along a lot of connotations or implications which may or may not be accurate concerning the abilities of Safe. As others have noted why choose Safe when you can use Power. Why, will have to be a part of the educational process. However proper perspective and understanding can start by not using Power in the name. I believe Power is not the right choice. Unsafe has also been proposed. I do not like this either because it is not accurate. Simply because something dangerous, foolish or stupid can be done using this method type does not mean it will be. Are we to label all objects "unsafe" simply because of the capacity of harm? Safety is in the hands of the programer. You cannot stop someone with the capability from doing something harmful if they choose. I would prefer the term Unrestricted or something similar. It simply denotes capabilities without implying it is dangerous. It isn't dangerous, it can be used dangerously, there is a difference. It is like many tools which can be used or abused. Hope this helps. Jimmie Houchin

use of objectValues() in DTML Methods vs. DTML Documents
by Mike Bannister 25 Oct '00

25 Oct '00

Hi, I'm working my way through the beta-book on zope.org and having a blast generally but I'm hoping someone can check my thinking here and tell me if I'm on the right track. Thanks in advance for any insight you can offer. In chapter 3, where DTML is first introduced, they have me create a Folder with some files in it and include something like this in a DTML Method: <dtml-in expr="objectValues('File')"> <a href="&dtml-absolute_url;"><dtml-var title_or_id></a> </dtml-in> Just for the heck of it I dropped that same code into a DTML Document in the same Folder and it didn't list the Files as I had expected. I understand pretty much the differences of Methods and Documents and I'm assuming the reason for this is related to the way the Documents exists in it's own namespace and the Method doesn't... so my best guess for this behavior is that the 'scope' of objectValues() is limited to the current namespace. Am I even close? If not can someone explain this to me? Thanks! Mike Bannister geekteam.com

How should a collection be in a Python product if i want to trave rse it with <dtml-in> rse it with <dtml-in>
by Max Møller Rasmussen 25 Oct '00

25 Oct '00

This is a question I guess has something to do with popping an object onto the namespace, or about me not understanding how stuff works. When I make a list of objects: class simple: def __init__(self, value): self.value = value theList = [simple(1), simple(2), simple(3), simple(4)] I would expect to be able to traverse it like below (The objects namespace would be popped onto the namespace.): <dtml-in theList> <dtml-var value> </dtml-in> But it isn't so. What do I need to do to make the objects namespace count in my traversal? (I'd like to keep the dtml as simple as possible.) -------------- If I make a list: theList = [1, 2, 3, 4] I can traverse it with: <dtml-in theList> <dtml-var sequence-item> </dtml in> --------- and if it's a list if dicts: theList = [{'value':1},{'value':2},{'value':3},{'value':4}] I can traverse it like: <dtml in theList> <dtml-let item=sequence-item> <dtml-var "item['value']"> </dtml-let> </dtml in>
