shapelib still didn't work for me.. help I've being trying different things for the pass day 1. I put the shapefile directly in the Extensions with the external method and it work fine import shapelib, dbflib def readshp(): shp = shapelib.ShapeFile('taiwan1.shp') return shp.info() and in zope <dtml-var expr="readshp()> 2. but when I save the shapefiles (taiwan1.shp, taiwan1.shx, taiwan1.dbf) into zope and call it using dtml it return the same error message. import shapelib, dbflib def readshp(filename): shp = shapelib.ShapeFile(filename) return shp.info() and in zope <dtml-var expr="readshp(taiwan1.shp)"> or <dtml-var expr="readshp('http://localhost/pytest/taiwan1.shp')"> The error message are 1. in "Run Zope in Console" Exception exceptions.AttributeError:"ShapeFile instance has no attribute 'thisown'" in ignored 2. in web browser Site Error An error was encountered while publishing this resource. Error Type: IOError Error Value: new_ShapeFile failed is there something wrong with how I constructed it? Do I need to do something before hand? 3. in error_log Traceback (innermost last): Module ZPublisher.Publish, line 115, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 41, in call_object Module OFS.DTMLMethod, line 143, in __call__ - <DTMLMethod at /testPython/test> - URL: http://localhost/testPython/test/manage_main - Physical Path: /testPython/test Module DocumentTemplate.DT_String, line 476, in __call__ Module DocumentTemplate.DT_Util, line 196, in eval - __traceback_info__: readshp Module <string>, line 1, in <expression> Module Products.ExternalMethod.ExternalMethod, line 231, in __call__ - __traceback_info__: (('http://localhost/testPython/taiwan1.shp',), {}, None) Module C:\web\ZopeInstance\Extensions\shapetools.py, line 4, in readshp Module shapelib, line 44, in __init__ IOError: new_ShapeFile failed ----- Forwarded Message ---- From: Dieter Maurer <dieter@handshake.de> To: Allen Huang <swapp0@yahoo.com> Cc: Zope <zope@zope.org> Sent: Saturday, December 23, 2006 3:52:53 AM Subject: Re: [Zope] problem with the shapelib module.. help Allen Huang wrote at 2006-12-21 23:23 -0800:
I want to do some mapping application with zope.. but I have run into this problem over and over..

Hmm. I doubt that you have really seen this text. There should be something in between the "in" and the "ignored". It is *vital* that you are as precise as possible in your problem reports... Python emits messages of the kind above in some (rare) situations, e.g. when exceptions occur in destructors. The exception above seems to have been raised in such a situation. The missing thing betwenn "in" and "ignored" should tell us which situation this was. It tells you that something tries to access the attribute "thisown" on a "ShapeFile" instance but this does not have the attribute.
in web browser Site Error An error was encountered while publishing this resource. Error Type: IOError Error Value: new_ShapeFile failed
Another tip for the future. When you report problems, you need to include full error information. Beside the "Error Type" and "Error Value" above, this also includes the traceback. You find all this information in the "error_log" object in Zope's "Root Folder" (Management Interface). -- Dieter __________________________________________________ Do You Yahoo!? Tired of spam?
