In the source ("OFS.Image.File.manage_upload").
def manage_upload(self,file='',REQUEST=None):
"""
Replaces the current contents of the File or Image object with file.
The file or images contents are replaced with the contents of 'file'.
"""
You are right when you point out:
Why does the integrated online help documents (the private) "update_data"
but not (the official) "manage_upload"?
I do not know.
I know that "manage_upload" is "official" because it has an
associated permission (and because it is used in the ZMI).
If you use "DocFinder" (or even "DocFinderTab"), then you can
easily see which methods are available in the various contexts.

Re: [Zope] How do I write to a text file from Python?
Hi Dieter,
Where is the 'manage_upload' function documented?
The problem that I had with manage_addFile seems to because I passed it a
unicode object rather than a string. The error message was "*'unicode'
object has no attribute 'seek'*" which led me to think a file-like object
was needed.
Thanks,
Jakob

It is ready to accept a string or a "file" like object
(usually, it gets a "ZPublisher.HTTPRequest.FileUpload" instance).

This is internal. The corresponding "official" method
is "manage_upload".

In an interactive Python session (under *nix: "bin/zopectl debug"):
>>> app.manage_addProduct['OFSP'].manage_addFile('test_file', 'test_content')
>>> tf=app.test_file
>>> str(tf)
'test_content'
The example shows you, that a string is accepted as "file" value.

Re: [Zope] How do I write to a text file from Python?
Hi Dieter By file object I meant the "OFS.Image.File" kind. I had two problems creating and modifying the file (at least). The first was that the manage_addFile() function that you mention seemed to insist on a os-file like object for the "file" parameter. I got some kind of seek error when trying to supply a string. But I might have done something else wrong. Appart from that I got a security error when I called the File.update_data() function. Using external methods I could call update_data() and import the StringIO python module that allows creating of string based file which I could in turn pass on to manage_addFile(). Well ... it works ... there may be a simpler way as you suggest. If you have some sample code I would like to see it. I am using zope 2.4.something.

It depends what you mean by "File object".
If you mean a Python "file", sitting somewhere on your file system,
then Andreas' advice is helpful.
If you mean a Zope "File" object (an "OFS.Image.File"), then
you would create the object in the standard way for creation
of Zope objects, that is:
destination.manage_addProducts[].().
For a "File" object, "" is "OFSP" ("Object File System Product"),
"constructor" is "manage_addFile" and the arguments are
"id, file='', title='', precondition='', content_type=''".
"file" is in fact the content that should be stored in your
"File" object. It can be a string or a "file" like object.
