checking the date
by Philippe Vignaux 21 Nov '03

21 Nov '03

Hi all ! I'm using Zope page Template with python scripts. I have a date in my form and when it is submitted, a python scripts checks the consistence of the date as follow : from DateTime import DateTime try: start_date = DateTime(REQUEST['datnais'],'central europe standard time') except: print 'error' return printed The date is inputed under this format : YYYY/MM/DD ex : 2003/02/15 The problem : the "error" message is always issued even when dates are ok (and whatever the date format). try: start_date = DateTime( REQUEST['datnais'] ) works but only accepts date under format YYYY/DD/MM as in the US but I have to work as GMT+1 Thanks in advance for any help. Our setup: Windows 2000 server ServP3 Zope 2.6.2 CMF 1.4 Ph.

Many thanks for your effective help. In attachment I send modified DT_Var.py file (from Zope 2.5.1) with this new function called "cut" and "etcc" (see below, extracted from comments). Attribute 'cut' will continue from number of cutted bytes:  inserts '... blah blah' After truncation, the value given for the 'etcc' attribute is added to the string. If the 'etcc' attribute is not provided, then '...' is used. Here are equivalent word-break as in 'size', but in reverse order for no missing words or letters. Both 'size' and 'cut' could be used for middle text extraction: '<dtml-var spam cut=3 size=10>' first make text shorter fot 10 bytes (as specified in 'size') and then from this shortened text was cutted first 3 bytes (as specified in 'cut'). So result text length is in adequate to 'size - cut' with respect to word breaks. Because I am not an experienced python programmer, I feel, that code could be rewritten to consume less memory. But it works nice and I think that it would be usefull if it will be present in newer Zope versions too. For easy reference, see lines 177 and 287-311 of that new code. Best Regards, J. Lukesh

Authenticating off an external server
by Ian Bicking 21 Nov '03

21 Nov '03

I'd like to authenticate in Zope off of another external server. So, say, user "bob" with password "secret" logs into Zope -- we then call https://otherserver.com/auth?username=bob&password=secret, parse the response, and the user is authenticated (or not) based the response. (We could also try the external URL with HTTP authentication, it just depends on the way the external server works) I looked into PluggableUserFolder some, and it seems possible but not particularly elegant -- the best I could figure out was creating a new PasswordEncryptionScheme which would do the web lookup, which is rather bizarre and obviously a hack. It seems like a useful thing to do, but I couldn't find any products that did this. Is there a better way to do this than this PluggableUserFolder hackish thing? Is there a product out there that I didn't find? Thanks. -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org

Changing Python's Date/Time Input Format
by Julian Clark 21 Nov '03

21 Nov '03

Hi All. I've got a minor issue with a form which takes a date and returns the string date. I'm wanting the input format to be able to accept any of dd-mm-yy, dd mon year, dd/mm/yyyy. Currently, it works for dd mon year, but it handles other input as mm/dd/yy. (which is kind-of un-natural for those using this form) how should I modify this python script... today=DateTime(input) return today.strftime("%d %B %Y") ... to alert Zope that the incoming string will be always in the order of dd mm yyyy? This is the traceback when the first tuple is not a valid month.  Cheers, Julian Clark

Re: [Zope] Zope 2.7 and ZEO

He rewrote it a couple days ago for > 2.7... here's the new link.... > http://my-zope.org/Members/kedai/News_Item.2003-11-15.5611 Those instructions was a little bit confusing, but I got it starting I think. zeo starts just fine when doing "zeoctl start". To run Zope I execute runzope and I get lots of messages. Although zope seems to run just fine, I can get into ZMI. How can I tell if ZEO works? Does ZMI show this somehow? Below is the end of the output when executing runzope. Why do I get lots and lots of zrpc-conn messages? Are those errors?

Re: [Zope] Why does Zope run multiple instances of z2.py by default?
by Lee J. McAllister 20 Nov '03

20 Nov '03

I'm running Zope2.6.2 on RH9 as well and see the same thing at start up time. I don't know enough about the Zope startup process to explain why they spawn the child but it usually terminates on it's own after the start up process has finished. My assumption is that, being a threaded process, it spawns a child to handle any requests/subprocesses so that it isn't blocked from receiving new requests while current ones are being handled.

Little change of DT_Var.py for dtml-var modification
by Jaroslav Lukesh 20 Nov '03

20 Nov '03

Hallo all, I want to add parameter "cut=###" to <dtml-var> tag. It is opposite for "size" parameter, at Zope 2.5.1 you can find it around line 260 of DT_Var.py. But after restart (*.pyc file successfully created) the modified tag <dtml-var file cut=200> does not cut anything, returns whole text from file instead file with missing first 200 chars... Does somebody have idea, where I need to change more? Many thanks, J. Lukesh DT_Var.py: if have_arg('size'): size=args['size'] try: size=int(size) except: raise 'Document Error',( '''a <code>size</code> attribute was used in a <code>var</code> tag with a non-integer value.''') if len(val) > size: val=val[:size] l=val.rfind(' ') if l > size/2: val=val[:l+1] if have_arg('etc'): l=args['etc'] else: l='...' val=val+l return val # added 'cut', opposite derivate from 'size' if have_arg('cut'): cut=args['cut'] try: cut=int(cut) except: raise 'Document Error',( '''a <code>cut</code> attribute was used in a <code>var</code> tag with a non-integer value.''') if len(val) > cut: val=val[cut:] l=val.rfind(' ') if l > cut/2: val=val[:l+1] if have_arg('etc'): l=args['etc'] else: l='...' val=l+val return val And I have defined here (around line 160) def __init__(self, args, fmt='s'): if args[:4]=='var ': args=args[4:] args = parse_params(args, name='', lower=1, upper=1, expr='', capitalize=1, spacify=1, null='', fmt='s', size=0, cut=0, etc='...', thousands_commas=1, html_quote=1, url_quote=1, sql_quote=1, url_quote_plus=1, missing='', newline_to_br=1, url=1)

Why does Zope run multiple instances of z2.py by default?
by Tim Edwards 20 Nov '03

20 Nov '03

Hi, I was just wondering why Zope runs multiple threads of z2.py by default? For example in my ps listing I have: zope 18183 1 0 10:25 ? 00:00:00 /home/zope/Zope/bin/python /home/zope/Zope/z2.py -u zope -f - p - zope 18184 18183 0 10:25 ? 00:00:10 /home/zope/Zope/bin/python /home/zope/Zope/z2.py -u zope -f - p - However one of my colleagues only has a single zope instance appear in his ps listing on his machine. His zope installation still runs fine. We are running Zope on Red Hat Linux 9. Does something like this make a difference?

Hello I'm using APE to copy back and forth from a FileStorage. And I need to set bobobase_modification_time (on the APE side) to help keeping things in sync. How could I do that? Gabriel Genellina Softlab SRL
