Re: Fwd: [Zope-dev] How to return downloadable content from Python Method
I am compressing files which need to be uncompressed inline
before download. The DTML href=... calles a python method
in the product which returns the uncompressed file data. Say
this file is an MSWord document, how do I return this as a file
to download? Presently, the browser just tries to display the
binary file and makes a mess of it.
Regards,
Simon B.
Hi Simon,
First off, please don't send HTML mail to the list.
You will have to set the Content-Type HTTP header to do that:
REQUEST.RESPONSE.setHeader('Content-Type', content_type)
where content_type is the right MIME type of the file you return, e.g.
something like 'application/msword' in your case.
Hope that helps.
Cheers,
Gregor.

Re: [Zope-dev] manage_debug
Hi Andy, Whoops, seems like some relict from the Client/Server Product, right?!? Actually I was planning to release a new version of that product, but unfortunately I have quit cdc in Frankfurt a while ago and I'm working for Iona Technologies in Dublin now, and now my work hasn't much to do with Zope any more. :( But, one of the last things I did for cdc was some work on this product and one thing was working on the encryption part, making it optional. Yet, I have the not really finished the code but I've taken it with me to Dublin. So, I hope to be able to spend one or the the other weekend working on Client/Server Product (as well as on ExtFile) and contribute a little to the zope community (to which I still have a great affection). So I will definitely stay on the zope- dev mailing list, follow the discussions and keep in contact with all you great Zopistas out there!

Re: [Zope-dev] (no subject)
Hi Menno, what you get from the form is a FileUpload object, so try this: print file.__dict__ and you will find out that it has a method called file.read() which returns the data of the uploaded file.

[Zope-dev] Product release: ExtFile/ExtImage 1.1.0.beta1
ExtFile/ExtImage Product 1.1.0.beta1 has just been released.
Get it at http://www.zope.org/Members/MacGregor/ExtFile
The new Version comes with many, many internal changes and some new features
which will (hopefully) make ExtFile/ExtImage even more reliable:
- You can set a 'level of undo' which determines in wich cases the external
file is overwritten/deleted or renamed to '.undo'.
- 'id collision bug' fixed, which caused unreferenced files in the
repository,
when an id of a new object already existed (thanks to Fred Yanowski).
Instead of in the __init__ method, the file data is now passed to the
object
after it has been successfully added, via manage_file_upload.
- 'wrong file size bug' fixed, which caused a wrong file size and resolution
of the image and preview, after a new file was uploaded followed by an
undo
of this transaction. The filesize and resolution attributes have been
replaced by corresponding methods which determine the respective value
directtly from the file(e.g. width(), height(), prev_size(), ...)
- Objects can be assigned an alternative id (instead of the filename) by the
optional 'id' field in the manage_add method of ExtFile and ExtImage.
- Uploaded preview images can be resized during upload (like the generated
previews).
- Images can be dynamically resized (thanks to Arno Gross): the index_html
method now has two additional parameters ('width' and 'height') which
cause
the image to be resized on the fly.
- Documentation updated.
Because the product was rewritten in big parts this release is a beta
version which might still have some bugs. I haven't had too much time for
testing, so please report me any bug you find. I hope I will be ableto
publish
the next stable release within the next two or three weeks.

Re: [Zope-dev] 2 Zopes
Hi, Can anyone tell me a way to get Zope Objects from the first Zope-Installation to the second. I need this because i have to program a Product to putting data into different Zope Installations from one point of the Web. My boss want this way because he want a central point for data input, where the data are of different type and therefore they have to stored in different locations( different Zope Installations) My idea is to use ZPublisher.Client, but i don't find a way to use it. thanks as if you need to copy the actual objects verbatim you might want to investigate exporting to zexp and using file transfer between the hosts and (using Client to faciltate calling into zope) importing them on the second server. The Client/Server Product is probably doing exactly what you want. It uses the Zope Export/Import facility to transfer whole objects from one Zope to another. You find it at www.zope.org/Members/MacGregor/Client_Server maybe you give it a try :) Cheers, Gregor! ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
RE: [Zope-dev] (no subject)
I recently asked how to read in and render the contents of
an external file, which doesn't work anymore using
Zope 2.2.2 an LocalFS' xxx.read(), and You responded that
The quickest solution for you would be an external method
that gets the file, performs the "read" and returns the result.
Now I use in an external method fsreadin a .py-module with
import sys
def readinfile (self, html):
"""Ralf Herolds way to read in local file objects."""
file = open(html, "r")
filecontent = file.read()
file.close()
return filecontent
which is referenced in a DTML method by
dtml-var "fsreadin('/tmp/var/thewantedtext.html')".
It works, but I almost cannot believe that this is that
simple - am I missing something, is security a concern?
It *is* that simple. The only problem is security. That way, you can read
*any* file that has read permission for the user, the zope process is
running on, e.g. everybody could use something like
http://your.host/fsreadin?html='/etc/passwd' to view your password file.
If you want to read files only from one directory, you could use:
import sys, os, string
def readinfile (self, file):
"""Ralf Herolds way to read in local file objects."""
file=file[max(string.rfind(id,'/'),string.rfind(id,'\\'),string.rfind(id,':'
))+1:]
path=os.path.join('/tmp','var',file)
file = open(path, "r")
filecontent = file.read()
file.close()
return filecontent
This would ensure, that only files from /tmp/var can be read.
Cheers,
Gregor!
