Ooops, replace "print self.data" with "return self.data" in the display method of my Testclass. ----- Original Message ----- From: "Chris McDonough" <chrism@digicool.com> To: "Espen Sorbye Frederiksen" <ceeesf@cee.hw.ac.uk>; <zope-dev@zope.org> Sent: Tuesday, January 23, 2001 6:46 PM Subject: Re: [Zope-dev] "Problem" using External Method
Espen,
The files that external methods actually live in are not Python modules, like normal Python modules. Though I haven't tried your example, it's likely that your reference to __main__ is confusing the external method machinery. Additionally, the output of "print" doesn't go to the remote browser, it instead goes to the console. You need to return a value to the caller for it to be displayed on the remote browser.
Try instead (as an example):
class Testclass: def setdata(self,val1,val2,val3): self.data = [val1,val2,val3] def updatedata(self, index): self.data[index] = self.data[index]+1 def display(self): print self.data
def createdata(): x = Testclass() x.setdata(10, 20, 30) x.updatedata(2) return x.display()

The module below works using the python compiler class Testclass: def setdata(self,val1,val2,val3): self.data = [val1,val2,val3] def updatedata(self, index): self.data[index] = self.data[index]+1 def display(self): print self.data
x = Testclass() def createdata(): import __main__ __main__.x.setdata(10, 20, 30) __main__.x.updateLog(2) __main__.x.display()
createdata() [10,20,31]
However if I try to add it as an External Method( id= createdata) it doesn't seem to work. I've tried to call it using <dtml-var/call createdata> without success. Any suggestions what I do wrong. I am grateful for all comments,
Espen
