I agree very much that the various default Zope components could be
much more rigid; this would make it easier to understand the
application flow and better realize when to subclass or replace.

If rigid means less configurable, then perhaps components could be
made flexible by better adapting to the objects given to them,
e.g. use the interfaces system to tell what kind of functionality
objects inhibit and provide flexibility through this route.

As such, instead of attempting to look up a custom traverser for an
object, ask the object "do you provide your own traversal
logic?". Instead of components being primarily pluggable, they could
be adaptive.

There are some existing products that might interest you. One is 
DocumentLibrary, a DMS system I wrote a while ago. Although it is not really 
maintained anymore, it could at least give you something to start from.

The other is ZopeVersionControl (available from cvs.zope.org), which is a 
product for performing application level (rather than database as Zope does 
out of the box) version control of Zope objects. To see how it is used you 
might also take a look at CMFStaging (also at cvs.zope.org).

Zope Corporation's Turbo Intranet might also interest you. It will give you a 
DMS w/version control and training on how to customize and extend it:

Re: [Zope-dev] (no subject)

[Dario Lopez-Kästen]

Hi,

First of all, I suggest that you start by looking into the following
Ready-To-Use Zope Apps:

CPS (www.cps-project.org), (www.plone.org), Silva
(http://www.infrae.com/products/silva)

These are systems that may allready have what you are looking for in terms
of functionality. If they serve your purpose, all you have to do is adapt
their look and feel to suit your needs. There are other's as well, IIRC -
perhps others can suggest them.

I any event, if you want to build your own, or want to learn enough to do
more than visual tweaking of the above, you would start by looking into the
Zope Book (if you haven't allready)
http://www.zope.org/Documentation/Books/ZopeBook/ and then the Zope
Developer's Guide, http://www.zope.org/Documentation/Books/ZDG/.

More docs can be found at http://www.zope.org/Documentation

And - you probably will have to read the source for Zope if you want to
understand how things really work.

Hope this helps. Good luck.

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.

Cheers,

Gregor!

To get the file content, you call the object's "read" method:

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!

[ralf . herold]

Hello Dieter, dear list readers,

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 
.

It works, but I almost cannot believe that this is that 
simple - am I missing something, is security a concern?

Thanks for answering, Yours. Ralf Herold

In earlier Zope versions, a method without a permission meant
"can be used freely". Now, it means "cannot be used via DTML/URL".

Thus, you must provide a permission for "read".
Unfortunately, "read" is not a method of "LocalFS" but from
the Zope objects wrapped around the files.
You, probably, will not want to change the respective Zope
sources.

The quickest solution for you would be an external method
that gets the file, performs the "read" and returns the result.

Alternatively, you may subclass the Zope object classes,
provide a permission for "read" and use them in
"LocalFS._create_".

RE: [Zope-dev] (no subject)

[Chris McDonough]

I was kicking the idea of making one around, but I don't think I'll have
time to do it.

There's a document on how to write a Zope database adapter by Chris
Petrilli at:

http://www.zope.org/Members/petrilli/WritingADA

Since the Python layer has been (well) done by Alex, it shouldn't be too
hard to make one if you're OK with Python.

Good luck!
