FTP behavior

I noticed the other day in an FTP client, when trying to do an 'mget *' from any folder other than the root/Application object (so, in OFS.Folder), that it prompted to get '..' (if interactive mode is on). Attempting to download this causes a warning, but nothing worse. Obviously, this problem is totally benign, but I wanted to see if this would be considered a bug?

Re: [Zope] problems with ws-ftp, firewall and zope web sever.

Was Zope running with the -D command switch? Look in z2.py. Remove the -D and try again. I have found that if -D (debug) is set, I can crash Zope by trying to FTP into it. This is apparently because the debug mode wants to print out messages to the console of the user who started it.

I was trying to ftp files to the zope web sever in my redhat linux sever. zope ftp uses port 8021 so After open ws_ftp, I clicked connected, in the session property/advaced i set the remote port number to 8021.network timeout to 60. in session property/General I set host name to my linux sever name which the zope websever reside in, I put the root manager name of zope website in the field of UserID and password and cliked ok it gives info as following: connecting to 128.192.47.24:34864 200 port command successfully. LIST 150 opening ascii node data connection for the list !timer cancelled blocking call !accept error: blocking call cancelled !Retrieve of folder list failed (O) I failed to do ftp with ws_ftp.

RE: [Zope] Variable sort, size in dtml-in
by Meilicke, Scott 19 Aug '02

Sorting by column is done within the zope management interface. Look at the code for examples.

SQL: nested select
by Bryan C. Andregg 19 Aug '02

19 Aug '02

I'm trying to generate a SQL query that includes a nested select tag, something like select * from models where name = ( select name from users where uid = <dtml-sqlvar uid type=int ) I can do this easily by itself, but I'd like to be able to use this with some other optional parameters controled by a sqlgroup tag, select * from models <dtml-sqlgroup where> <dtml-sqltest foo type=nb optional> <dtml-and> <dtml-sqltest bar type=nb optional> <dtml-and> ... My Test Here ... </dtml-sqlgroup> How does one nest that select call in the DTML? Cheers, -- Bryan C.

aquiring objects upward in DTML
by Dan Jacobs 19 Aug '02

19 Aug '02

Hi, Is there an easy way within a DTML method to acquire a named object that may be anywhere upward. At the moment I'm looking at the parent by doing aq_parent['name'] but that only looks one level up. I tried aq_acquire('name') and aq_parent.aq_acquire('name') but they don't work. Thanks, Dan

rendering client object in dtml method
by Dave Peticolas 19 Aug '02

19 Aug '02

Hello, I am a Zope beginner and have a hopefully simple question. I want to use a dtml method to format the content of a dtml document which is the client object when the dtml method is called. For example, <http://dtml_doc/dtml_method> would, if I understand correctly, invoke dtml_method with dtml_doc as the client object. Given my understanding, I would think a statement such as the following in dtml_method ... <dtml-var this> ... would produce the rendered contents of dtml_doc appropriate for display, i.e., the contents you would get with <dtml-var dtml_doc>. However, said statement results in the rendered contents of dtml_doc with the html special characters escaped to display literally rather than be intepreted by the browser. How can I get the unescaped version of dtml_doc's rendered content? thanks, dave

sql_quote and missing text!
by Greg Conway 19 Aug '02

19 Aug '02

Hi all, Sorry, having a 'sorting out all those niggling little bits' afternoon.... :) When I insert text into a MySQL Database, I always end up with a scenario where users enter the ' and " character. I've read up, and found my_sql quote for dtml-vars, that should do the trick. BUT.... what seems to happen after a while, if several ' characters get entered, is that the text that has ended up between two ' characters disappears! Anybody know of anything I can do about this? many thanks! Regards, Greg Conway.

CopySupport for my objects

I have a python product that is defined like this:: class IssueTrackerNotifyable(SimpleItem.SimpleItem, IssueTracker) and the class IssueTracker looks like this:: class IssueTracker(Folder.Folder, CatalogAware, Persistent ) The objects created with IssueTrackerNotifyable work fine as they are but I can't copy them and place them elsewhere. Not even in another IssueTracker class instance. What do I need to base-inherit to get complete CopySupport? --- Outgoing mail is certified Virus Free.
