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', } ........................................................ -- jean
