RE: [Zope] application/octet-stream vs. application/msword
Hi Dieter all The problem is, currently, not interesting enough for me to analyse is seriously. I can well understand, I wish I could forget about it :( If you know, that you add only "*.doc" files I add .doc, .zip, .exe (self-extracting zip), .pdf and .ppt ... so the quick and dirty route won't save me this time ..

If you know, that you add only "*.doc" files in your
"ccDocClass_add, why not add
explicitely "content_type='application/msword'", i.e.
dtml-call "manage_addFile('', file, '',content_type='application/msword')"

RE: [Zope] application/octet-stream vs. application/msword
Hi Dieter all
How does Zope recognize the type of a file?
It uses "OFS.content_types.guess_content_type"
OK, so 'manage_addFile' uses 'guess_content_type'?
I'm a bit confused here .. I see three lists of content
types, excerpted below. They are in:
1. 'lib/python/OFS/content_types.py'
2. 'bin/lib/mimetypes.py' and
3. 'ZServer/medusa/mime_type_tabel.py'
There is some overlap between the lists (eg. '.doc' occurs
in 1 and in 3, and '.cdf' occurs in all three). What relation
is there between the lists?
The other thing I'm wondering is, it looks as if '.doc' should
*always* be recognized as msword. How could it sometimes turn up
as octet-stream? To add documents I call:
a href="manage_addProduct/ccDoc/ccDocClass_factory"
Add a document./a
The initial method of 'ccDocClass_factory' is 'ccDocClass_addForm',
and that form's action is 'ccDocClass_add' which eventually calls:
dtml-call "manage_addFile('', file, '')"
So how come '.doc's get added as application/octet-stream ?
Excerpts:
-
In 'lib/python/OFS/content_types.py' I find:
# This gives us a hook to add content types that
# aren't currently listed in the mimetypes module.
_addtypes=(
('.cdf', 'application-x-cdf'),
('.doc', 'application/msword'),
[...]
('.xul', 'text/xul'),
)
and in 'bin/lib/mimetypes.py' I find:
types_map = {
[...]
'.bcpio': 'application/x-bcpio',
'.bin': 'application/octet-stream',
'.cdf': 'application/x-netcdf',
'.cpio': 'application/x-cpio',
'.csh': 'application/x-csh',
[...]
'.zip': 'application/zip',
}
and, finally, in 'ZServer/medusa/mime_type_tabel.py' I find:
# Converted by ./convert_mime_type_table.py from:
# /usr/src2/apache_1.2b6/conf/mime.types
#
content_type_map = \
{
[...]
'cdf': 'application/x-netcdf',
[...]
'doc': 'application/msword',
[...]
'zip': 'application/zip',
}

[Zope] application/octet-stream vs. application/msword
Hi Zopers How does Zope recognize the type of a file? Mostly it recognizes .doc's correctly as 'application/msword', but sometimes they turn up as 'application/octet-stream'. Others, like .fh8 (Freehand) and .exe (self-extracting zip) are (unsurprisingly) also turning up as 'application/octet-stream'. The files are being added using input type=hidden name=":method" value="manage_addProduct/OFSP/fileAdd" Can Zope be taught more types? Failing that, I guess I should try to catch the extension using "find(S, SUB[, START])" on the id (which is the filename). -- jean ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

Failing that, I guess I should try to catch the extension using "find(S, SUB[, START])" on the id (which is the filename). When you say understand filetypes, Zope just looks at the xtension and matches it to some known file types. you can add any custom mappings you need to the content_types.py file in the OFS dir. these functions get called for identifying file types.

It uses "OFS.content_types.guess_content_type" (look at the source in OFS/Image.py), unless the manage_addFile specifies an explicit "content_type". Can Zope be taught more types? Look at the source of "OFS.content_types".
