It tells you where the error occurred. The code you show above should not result in an "AttributeError: read". However, it has some other problems: * "manage_addFile" has read the uploaded file; after the call, it is positioned at its end. Your "read" will therefore always return ''. You should call a "seek(0)" before you try to read the file again. * Your code is less well readable than possible. This could be improved by a definition "file = request.form['the_file']" and than using "file" rathen than "request.form['the_file']" over and over again. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

But with python there always is a way, eg There is no meta-type FILE but only File. But this does not matter in this case since an uploaded file *does* have a read() method. The code looks mostly ok. I would look directly at the REQUEST object to figure out what the request really contains. -aj pgp9w4kR7WBK3.pgp Description: PGP signature ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

I have the following DTML document:
Select the file:

And here is the checkTheFile python script:
## Script (Python) "checkTheFile"
##bind container=3Dcontainer
##bind context=3Dcontext
##bind namespace=3D
##bind script=3Dscript
##bind subpath=3Dtraverse_subpath
##parameters=3D
##title=3D
##
# Import a standard function, and get the HTML request and response objec=
ts.
from Products.PythonScripts.standard import html_quote
request =3D container.REQUEST
RESPONSE =3D request.RESPONS
filename=3Dhtml_quote(request.form['the_file'].filename)
context.fs.rpt.manage_addFile(filename, request.form['the_file'],
content_type=3D"text/xml")
# the next line does'n work:
file_content=3Drequest.form['the_file'].read()
# EOF
I need to temporary save uploaded file then I have to validate it. But
I've received the following error message:
Site error:
Error Type: AttributeError
Error Value: read
I've tested it on zope 2.7.7 and 2.9.0 on suse 10.0. (python 2.4.1).
So, It is obvious to me that I've made a mistake, but I have no idea
where it is?
I hope that someone could show me the right way
Best regards to all,
Janusz
Janusz,
Zope objects of meta-type FILE do not have a read(). But with python
there always is a way, eg
ListOfLines = str(context.someFileObject).split('\n') # if its a
delimited file, this has worked for me in the past
for line in listOfLines:
doValidations(line)
?
