[Zope] picture as parameter for an external method

[VIGNAUX Philippe]

Hi !

 

Is there a way to pass a picture (extension JPG)  as a parameter of an
external method.

 

It seem to be the case as read on the internet but for me it doesn't
work !

 

 

 

My zope config :  Zope 2.6.4 (binary release, python 2.1, win32-x86),
python 2.1.3, win32

 

 

This is the problem :

 

 

1) I've got a page template where I can choose a picture thru a < file >
object :

 

<input type="file" name="filename">

 

 

 

2) This page template calls a python scripts

 

request=context.REQUEST

context.my_external_function( original_id=request['filename'] )

#context.my_external_function( request['filename'] )

 

 

 

3) my_external_function is defined in an appropiate module in the <
Extensions > folder of my zope installation

def my_external_function (self, original_id):

     pass

 

 

PROBLEM :   when i run the process i get an error :

 

exceptions.AssertionError

Sorry, a site error occurred. 

Traceback (innermost last): 

*	Module ZPublisher.Publish, line 150, in publish_module 
*	Module ZPublisher.Publish, line 106, in publish 
*	Module Zope.App.startup, line 225, in abort 
*	Module ZODB.Transaction, line 135, in abort 
*	Module ZODB.Connection, line 256, in abort 

 

When i configure the whole thing to pass a normal parameter (text), it
works normally ;  so obviously the problem is when trying to pass a
picture.

 

 

 

Any idea ????

 

Thanks

 

 

Philippe
