OT: documentation systems.
by Terry Kerr 19 Oct '00

19 Oct '00

Hi, What documentation systems to people use for developing offline hardcopy and online user documentation for applications that they develop? I am writing an extensive application using zope, and it needs a lot of user documentation. The system I use won't necessarily have to be web based...I just wants something that is effect. terry -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions Pty Ltd (www.adroit.net) Phone: +613 9563 4461 Fax: +613 9563 3856 Mobile: +61 414 708 124 ICQ: 79303381

Help needed with news articles
by Taco Scargo 19 Oct '00

19 Oct '00

Basically I want to create a page listing the last 4 articles from a Zope folder. The articles need a publish from/to field, title and (dtml) text. I somehow need to be able to find and display the article from another dtml document. I read many FAQs and tried working with zcatalogs, but somehow I am not getting there. It is probably not so difficult. If there is somebody how can help me or give me a link to a clear explanation or example I would be very very grateful. Thanks ! Taco

Python/Perl methods?
by Oliver Sturm 19 Oct '00

19 Oct '00

Hi, I've been looking at that new book's draft on the Zope website and I'm wondering what chapter 7 is talking about. Where in Zope can I find a "restricted Python method" or a "restricted Perl method"? I've never seen those. Does anyone know, please? Best regards, Oliver mailto:sturm@oliver-sturm.de

Z2.log question
by George Osvald 19 Oct '00

19 Oct '00

Can I safely delete Z2.log file and replace it with an empty one? It is getting quite big and it seems to me like a waste of space. I downloaded the existing version for reference. Regards, George

Tiny tables
by Graham Chiu 19 Oct '00

19 Oct '00

I would like to run some regular reports based upon sqlmethods. The input to these are a mixture of normal values, and some tokenised values. I tried storing these in tiny tables, but it doesn't seem that tiny tables allow one to store tokens. If I specify the value as say, criteria:tokens, it gets changed to just criteria. Any suggestions as to how to store the input as tokens for my reports? -- Graham Chiu

debugging zope?
by Riku Voipio 19 Oct '00

19 Oct '00

Hi, I'm running zope 2.1.6 on Linux with DCoracle on "production", and about once in week zope runs out of control, like it would be in a infinite loop. Stops responding to zserver requests. Any hints on how to find out what's going on? -- Riku Voipio riku.voipio(a)tietoenator.com 09-862 60764

OT: Zope/ReportLab/PDF generate left aligned tables
by Andreas 19 Oct '00

19 Oct '00

Hi, Is anybody out there using ReportLab PDF library ? I successfully installed ReportLab and PIL to serve out pdf files with Zope. Now I'm in trouble with reportlab.platypus.SimpleDocTemplate ,Table. I can't figure out how to draw a table left aligned on a PageTemplate. I can set several styles of table cells but wehrer can I set the alignment of a table within it's frame? ################## # myZopeTable.py # ################## import string from reportlab.platypus import Image,Table, TableStyle, SimpleDocTemplate from reportlab.lib.units import inch, cm from reportlab.lib import colors from reportlab.pdfgen.canvas import Canvas from reportlab.lib.pagesizes import A4, landscape from reportlab.pdfgen.textobject import PDFTextObject from types import * class buffer: def __init__(self): self._buffer = [] self._size = 0 def write(self,line): self._buffer.append(str(line)) def read(self): data = string.join(self._buffer, '') return data def tell(self): return len(self._buffer) def myPage(canvas,doc): canvas.saveState() canvas.setPageCompression(1) canvas.setFont('Times-Roman',9) canvas.setAuthor('andreas(a)aHit.de') canvas.drawRightString(doc.leftMargin+doc.width,10,"Page %d" % doc.page) canvas.restoreState() def helloworld(self,req): stream = buffer() res=self.SqlWizardQuery() # ZSQLMethod data=[] for i in range(len(res)): row=res[i] items=[] items.append(req.sq+i) for j in range(len(row)): items.append(row[j]) data.append(items) t=Table(data) t.setStyle(TableStyle([('INNERGRID',(0,0),(-1,-1),0.25,colors.black), ('BOX',(0,0),(-1,-1),2.0,colors.black), ('ALIGN',(0,0),(-1,0),'CENTER'), ('ALIGN',(0,1),(0,-1),'RIGHT'), ('FONTSIZE',(0,0),(-1,0),8), ])) lst = [] lst.append(t) doc = SimpleDocTemplate(stream, pagesize=landscape(A4), leftMargin=2*cm, rightMargin=2*cm, topMargin=2.5*cm, bottomMargin=2*cm ,showBoundary=1) doc.build(lst,myPage,myPage) return stream.read() -- _________________________________________________________ Andreas Heckel andreas(a)aHIT.de

A clarity problem...
by Curtis Maloney 19 Oct '00

19 Oct '00

Green things, After seeing yet another problem caused by the 'shorthand' of zope (using "foo" to mean expr="foo") I was wondering just how difficult it would be to REMOVE this useful, but confusing, feature. Personally, I don't have a problem with it, any more. But it seems a sizable portion of traffic on this list is because of people who do. (True, it seems to have dropped off in recent weeks... is this because there is better doco, or have newbie numbers dropped?) Even if it were a build time option or something... just rambling...

Re: [Zope] ZSQL Method & AUTHENTICATED_USER
by Jon Prettyman 18 Oct '00

18 Oct '00

I'm pretty sure that all variables have to be passed in explicitly with SQLMethods. Namespaces are not passed in. Try specifying username as an argument in the ZSQLMethods edit form and pass it in like this: <dtml-in expr= "lookup_by_username(username=REQUEST.AUTHENTICATED_USER.getUserName()"> (Untested....) -jon Aaron Straup Cope <asc(a)vineyard.net> writes: > Hi, > > I'm trying to perform a simple MySQL lookup based on the > AUTHENTICATED_USER.
