ZServerFTP

HomeSite's FTP mode is apparently trying to use the FTP commands "MODE S" and "STRU F" to which ZServer is responding with a "500 '%s': command not understood." % command and then HomeSite bails out and never fetches any directory listings or anything. Is there any intent to support these commands? It sure would be nice. -- Robin Dunn robin(a)AllDunn.com http://AllDunn.com/robin/ http://AllDunn.com/wxPython/ Check it out!

debugging ZServer FTP sessions.
by Anthony Baxter 04 Mar '99

I'm attempting to use ZServer's ftp daemon to upload a number of images into my database, however no matter what I try I always get back ftp> put sidebar.gif local: sidebar.gif remote: sidebar.gif 200 PORT command successful. 150 Opening Binary connection for sidebar.gif 550 Error creating file. 189 bytes sent in 0.00139 secs (1.3e+02 Kbytes/sec) ftp> I've tried this with an image that doesn't exist, as well as for one that already exists. Is it just a matter of "it doesn't work for images" or what? Also, where does ZServer send errors from ftp sessions? It looks to me like it's just silently eating them. :( Anthony

Indirect variable references
by Timothy Grant 04 Mar '99

04 Mar '99

Hi, I'm going to try this one again with--hopefully--a little more clarity on my part. I am working on a Zope application that builds a page based on the contents of two Tiny Tables The first table provides categories, and the second provides detail for each category. DTML works beautifully to allow me to build the page. The code is as follows:  <tr> <td> <B></B> </td> <td> <select name="" size=1>  <option>   </select> </td> <td> </td> </tr>  As you can see the code builds a number of select boxes that are named with the names that are contained in the first Tiny Table. After the form has been submitted, I need a way of accessing the contents of those select variable names, and I cannot figure out how to do it. e.g., if the Tiny Table contains Fred, Ethel, Ricky and Lucy, I will get four select boxes named Fred, Ethel, Ricky and Lucy. It works fabulously, even though I knew it should work, I was still pumped when I looked at the HTML and saw what a nice job had been done. So after submission, Fred, Ethel, Ricky and Lucy all contain the value of what was selected. How do I programatically or should that be DTMLmatically access those values from within another #in construct? Thanks for any assistance. -- Stand Fast, tjg. =================================== Timothy J.

RE: [Zope] DTML Method vs Document [ZDP?]

Everything seems to work. > > What is the difference between a DTML document and a DTML > method? Seems to > me a method should not be surfable but they are. > This is my take on the situation. As far as I can tell this is pretty deep voodoo. A DTML Method is what used to be just a Document in pre 1.10 releases. DTML Methods are not objects, they are methods. If you have a folder called foo, and it contained a DTML Method called bar, then bar is a method of foo. foo doesn't contain the object bar, it has the method bar bound to it. What this means is that from bar's point of view, 'self' is a Folder object, and any properties it sees are properties of foo, not itself. DTML Documents are Zope Objects. Their idea of 'self' is themselves. They are contained in folders, but are not methods bound to that folder, they are instances of DTMLDocument.DTMLDocument. They can manage their own Properties (because they inherit PropertyManager.PropertyManager). Both DTML Documents and DTML Methods can hold DTML and content. The difference is subtle. DTML Methods would be used when the answer to the question 'Am I showing some other objects content through me?' is Yes. DTML Documents should be used when the answer to the question 'Am I the content I want to display?' is Yes. DTML Methods have the advantage that they don't have any properties, and their perspective of aquisition is from their containing folders point of view. DTML Documents have properties which may interfere with aquisition you'd want to do, and aquisition is from their own point of view, which may not be what you want. (BTW Martijn, perhaps the above should go in the FAQs) If this isn't clear to you don't worry, it isn't even really clear to me. There is no way, but there really should be a way to convert between the two because the roles for a DTML widget may change from Method to Document as your system evolves. This will probably be a feature in the next release.

etcUserFolder Product
by Michel Pelletier 03 Mar '99

03 Mar '99

Greetings, (This is crossposted because it is a product anouncement, and contains interesting developer pointers) I've have massaged the source code for UserDb and created a new user folder products called etcUserFolder. This products authenticates off of a flat file of usernames:cryptedpasswords. If there is anything trailing the crypted password it is ignored, so any /etc/passwd file will work. It is generaly not recommended, however, to use your /etc/passwd file for security reasons. This is an unsuported product and has been written because it was asked for a few times, and I felt the community could use another good example of writing user folders. It also shows off cookie authentication which Brian perfected with UserDb. Here is the documentation: etcUserFolder requires a directory called 'etcUsers' in which to place your file containing the uid:pwd pairs. This directory may be an INSTANCE_HOME (typicaly your top level Zope dir), SOFTWARE_HOME (typicaly 'lib/python') or in the etcUserFolder directory. Jim wrote a nifty function called getPath that sniffs all of these places for a directory and file of your choosing. This function is included in etcUserFolder and will be included as a standard function of the next release. Other Product authors may find it interesting. Since the flat file is meant to be b/w compatable with /etc/passwd and htpasswd style files, there is no Role associated with the users it authenticates. You can specify a default role which is, by default, 'etcUser'. I have not done extensive testing of this, therefore it is a pre-release. Please send bug-reports and hopefully a patch to me (michel(a)digicool.com) http://www.zope.org/Download/Prereleases/etcUserFolder/etcUserFolder.tar .gz -Michel

Is it possible to have a filter on the mailing lists that will drop any posts on the main zope site that appear to be cross-posted on the zope-dev site? Pavlos

count of items in group?
by julian＠zereau.net 03 Mar '99

Using the "in" tag's grouping capability, is there any way to get the count of items in that group? I need this so I can have a table with one row per item and a cell rowspanned for all the group's items (eg: related products and their picture). --- Julian Morrison Programmer (Zereau Ltd)

I'll create the preliminary docs which they will improve and use for the course. Thus I'll have some some material for a (perhaps four day) training course to contribute. BTW, is there any interest here in a Zope training course? --Paul
