[Zope-dev] python scripts and variables
Hi,
I ve got a little problem:
I am starting a python script within a python script.
how do i pass the variables from one to the other?
(i tried setting the request variables and getting the values by the
python script but it didnt work)
it looks like this:
Python-Script:
code of python script1
container.REQUEST.set('value', '123') -I tried this but my
script didnt get the value
container.py2 Second python script should get values by the
request variable
code of python script1

Use the parameter list. container.py2 Second python script should get values by the request variable This way, the script isn't even called - to call a method in python you have to use () after it, optionally filled with parameters. But you should be able to pass parameters around using the request, too. Just call your method in the context. jens ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] python scripts
Hi, This weekend I did some work on python scripts and found some things which suprised me, can someone enlighten me on this why these 'strange' things are needed? : 1. When calling a method from a python script you've to do this : (assume x is the value to pass and name is a parameter of mymethod) context.mymethod(name=x) The following doesn't works : context.mymethod(x) (this gives an error) Why 2. Assume you've an sqlmethod which expects 2 parametes, but one is optional : eg select * from invoice dtml-sqlgroup where required dtml-sqlgroup dtml-sqltest customersid column=customers_id op=eq type=int dtml-and dtml-sqltest productsid column=products_id op=eq type=int optional /dtml-sqlgroup /dtml-sqlgroup So, you could run this sql with or without the productsid No, calling from python script doesn't works since it expects: context.mymethod(customerid=..., productsid=...) while context.mymethod(customerid=...) doesn't work.. Now, this implies that I've to write 2 sqlmethods (one with 2 parameters and one with 1), which is pretty stupid, since sqlmethods perfect allow to ignore a parameter when not passed... Can somebody tell me more on this? Why this is the case and perhaps a solution for (2) Thanks in advance, Tom Deprez ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] Python Scripts Bug Question
Hi, Got a bug and an old unanswered question: The Bug: If I use an name other than 'context' to bind to context, I quite often (but not always :-S) get a KeyError on that name. The Question: If I'm calling a Python Script from a Python Product (for example), how would I pass a namespace to the script that would get bound as the namespace argument? cheers, Chris ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

From: Chris Withers [EMAIL PROTECTED] The Bug: If I use an name other than 'context' to bind to context, I quite often (but not always :-S) get a KeyError on that name. I'll check this out. It's in the Collector, right? The Question: If I'm calling a Python Script from a Python Product (for example), how would I pass a namespace to the script that would get bound as the namespace argument? Treat it as a keyword argument. "Caller's namespace" is the only one of the binding names that behaves this way, since the caller has complete control over the contents of the namespace anyway. For example: myps(_=ns) Cheers, Evan @ digicool 4-am ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

If you called it "fred" on the bindings tab, pass it as "fred". rats :-( How hard would it be to make it work like that though? I wonder if that's not the root of the bug I reported? I'm calling a python script with the context bound to, lets say, 'fred'. I call the python script like this: result = self.aq_acquire(variable_containing_name_of_PS)(a_dictionary) ...where self is an instance of my python product, and a_dictionary, is, well, a dictionary that's aimed at the specified parameter of the python script.

I just wondered if the way I was calling it might have had something to do with cotnext not being bound to its correct name. cheers, Chris ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

[Zope-dev] Python Scripts update
Python Scripts have gone through a fair number of changes and bugfixes recently. They should now work properly as methods of ZClasses. When you download the source of a Python Script, the title, parameter list, and bindings are added to the source in the form of specially formatted comments. If source with these comments is uploaded or pasted into a Python Script, it will properly set the properties mentioned in the comment block. The default bindings have been changed to be more sensible. If you want to give Python Scripts a try, you can go to http://ps.4-am.com:9000/ , pick a password, and you'll get your own private area in a trunk CVS checkout of Zope in which to play. I promised examples when I first announced this site, and haven't gotten around to writing any. If you have created a script or set of objects on the demo site that you would like to share as an example, please mail me the URL.
