Daniel,
Thanks for your example. I don't think this is exactly what I want. I probably
should have given a small example.
MasterPage
-------------------
<html xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
metal:define-macro="master">
<body>
Here I want to make a call to a python script here that will take
as parameters 3 values and return the result as (lot's of table rows that vary of
course depending on the 3 parameters passed in)
html that will get inserted in the page being served.
But the three values are to be "set" in the PageTemplate that is using this master
macro by doing a "use-macro".
Here is other html including
<div metal:define-slot="main">
If you supply a tag with a 'fill-macro="main"' attribute
when using this macro, that tag will replace this text.
</div>
</body>
</html>
-----------------------------------
PageTemplate A
<div tal:define="global firstVal string:foo;
global secondVal string: bar;
global thirdVal string:biff"></div>
<html xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
metal:use-macro="here/masterTemplate/macros/master">
</html>
------------------------------------
What I need to know is what syntax do I use to get the firstVal, secondVal and
thirdVal passed to the
python script I want to call?
Daniel, I think you're example is showing me how I can get a value that was set in
the python script to be accessible from
the page. I want to know how to get the 3 values set in PageTemplate A into the
python script. What is the syntax to make the call,
so that I can reference those variable names in the python script?
Simple 1 variable example which I've tried but doesn't work:
If I had:
Master Template
-------------
<html xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
metal:define-macro="master">
<body>
<h1 tal:content="/here/myPythonScript">junk</h1>
<div metal:define-slot="main">
If you supply a tag with a 'fill-macro="main"' attribute
when using this macro, that tag will replace this text.
</div>
</body>
</html>
PageTemplate A
------------------------
<span tal:define="global name string:Foo"></span>
<html xmlns:tal="http://xml.zope.org/namespaces/tal"
xmlns:metal="http://xml.zope.org/namespaces/metal"
metal:use-macro="here/masterTemplate/macros/master">
expanded stuff in here .... including
<div metal:fill-slot="main">
my custom content gets put in here
</div>
<html>
MyPythonScript (just for example) looks like this and has a parameter list of
name="World":
--------------------------------
return "Hello %s." % name
What I want is for the value of the name variable set in PageTemplate A to "Foo"
to be accessible to the MyPythonScript so that it ends up returning "Hello Foo"
instead of "Hello World"
Thanks,
Lynn
