[Zope] Two more questions

Hi Joe,

Change your external method def's to have Categories = something else
than "". It could be that the ISLines function is creating the error
because it does not like the zero length string.

Thanks again.  Still no go although it looks like it's getting closer.
I tried this;

<tr tal:replace="item python:here.GetISLines(FY=request.FY,
Per=request.Per)">

To my programmer eyes, that looks like it might be correct. I got a
really strange error though;

Error Type: TypeError
Error Value: unsupported operand type(s) for -

Does this mean that I have an unsupported operand for the nothing after
the dash or is it for the dash? There's no dash in the statement so I
guess I have an unsupported operand for nothing :~{

P.S. Tim, sorry for sending this message twice.  When I reply it goes
directly to the source instead of the list and I forget to type the
zope at zope.org before I send it.

Hi Joe,

I had another look and realized I was doing the wrong thing ;)
Try this instead.
<tr tal:repeat="python:here.GetISLines(FY=request.FY;Per=request)">

Thanks Tim,

It didn't work.  I get a SyntaxError on the question mark. Specifically;

Compilation failed
TAL.TALDefs.TALError: Python expression error:
    GetISLines?FY=request
              ^
SyntaxError: invalid syntax in expression
'python:GetISLines?FY=request', at
line 10, column 5

This brings up more questions.  I assume that GetISLines is looked up
through acquisition.  FY is the name of one of my parameters.  How does
it
know that I want the FY attribute of the request object?  Also, how
would I
pass two parameters?  "GetISLines?FY=request;Per=request"?

Sorry about the last email :)
In answer to the second question
Try something like this:
<tr tal:repeat="item python:GetISLines?FY=request">

I really hate to keep bothering everyone but I'm still running into
things I
don't understand.

In order to keep my table headers consistent across reports, I have them
stored as a separate DTML method called IS_Ptd_Header.  In my main
Income
Statement, I have this where I want the table header to show up;

<span tal:replace="structure here/IS_Ptd_Header"></span>

This works fine.  The problem I've run into is when I want to use tal
tags
in the header like this;

Income Statement for period <span
tal:replace="request/Per">Period</span>

If I have this line in the Income Statement, I get the Per parameter
from
the URL. The same line in IS_Ptd_Header gets ignored so the resulting
page
shows "Income Statement for period period".  I thought that maybe the
tal
tags were being ignored because IS_Ptd_Header is a DTML method so I
created
a ZPT with the name IS_YTD_Header and used that in the tal replace
command
but the result came back as HTML quoted text instead of the actual HTML.
Anyone know what I'm missing?

Second problem.  I have an external method called GetISLines.  The
actual
function being called looks like this;

def GetISLines(FY = 2, Per = 12, CatType = "Grp", Categories = ""):
   c = ISLines(FY, Per, CatType, Categories)
   return c.DefLines

I've been doing all my testing using the default arguments with this tal
tag;

<tr tal:repeat="item here/GetISLines">

I need to pass in the URL parameters but I can't figure out how to do
it.

<tr tal:repeat="item here/GetISLines(request.FY)"> doesn't work.
Nothing
else I've tried works either.  How do you pass parameters to an external
function?

Thanks.

Joe Goldthwaite
