dtml-in over the output from my method
by Tim Hicks 07 Nov '00

I am trying to create a zope product in python but have got stuck with using the dtml-in tag to iterate over a method (or is it a function? I get a little mixed up) of my class. Here is the method, def list_messages(self): lr = open(self.user_dir+'/msg_list', 'r') spl = re.compile('\s\|\s') for msg_line in lr.readline(): num_from_sub = [] num_from_sub = spl.split(msg_line, 2) print num_from_sub self.msgnum = num_from_sub[0] self.msgfrom = 'This is from UNKNOWN' self.msgsub = 'My special subject' return self.msgnum, self.msgfrom, self.msgsub And here is an extract from the dtml file that is supposed to display the output, <dtml-in list_messages> <tr> <td><a href="/spool/&dtml-user;/get_message?&dtml-msgnum;">&dtml-msgfrom;</a></td> <td><a href="/spool/&dtml-user;/get_message?&dtml-msgnum;">&dtml-msgsub;</a></td> </tr> </dtml-in> However, this does not produce the desired effect. I don't know if it is obvious from what I've written, but basically, the three variables (self.msgnum, self.msgfrom and self.msgsub) are supposed to be inserted into the appropriate place in the table, and then the 'for' statement re-executed (producing different values for the variables) with the subsequent values being inserted into the next line of the table etc... until there are no more lines to be read from lr. I'm not sure if that is clear or not, sorry. Obviously, this does not work as the dtml-in simply iterates over each of the returned variables (instead of over the for statement). I can't seem to make it do what I want. Does anyone have any ideas? Much obliged if you do. Cheers tim

testing a product, then it disappears after restart
by Tim Hicks 07 Nov '00

07 Nov '00

I am trying to create a zope product and it basically works in python, so I thought I would start trying to 'zopify' it. I created a directory in the zope Products directory called zIMAP and placed my code in there, along with a __init__.py file to initialise the product. Here is what it looks like, import zIMAP def initialize(context): """Initialize the zIMAP product. """ context.registerClass( zMAP.zimap, constructors = (zIMAP.manage_addzIMAPForm, zIMAP.manage_addzIMAP), icon = '') The main bit of my product code is in a file called zIMAP.py. When I restarted zope, my zIMAP product appeared in the product management list (broken, as I'd expected). I looked at the debug info that zope provides for broken products and made some changes to the code... followed by restarting zope. I then got a different error from the broken product info screen. However, when I made changes to the code and restarted zope this time, it was as if I had done nothing. The same error was there (despite that particular line of code being different, and in fact at a different line). I could not make zope recognise my changes no matter how many times I restarted zope. So I tried deleting the product from the product management screen. It did indeed go away, but now it won't come back! When I delete any other working product, it simply reappears next time I restart zope. What has gone wrong with my product? How can I make zope recognise it again? I have included the top of my zIMAP.py file as well in case it is required. I'd really appreciate any help. tim top of zIMAP.py import imaplib, re, string, sys, os, DocumentTemplate import Globals from Globals import Persistent, Acquisition import AccessControl import OFS class zimap ( Acquisition.Implicit, Persistent, AccessControl.Role.RoleManager, OFS.SimpleItem.Item, ): """zIMAP - Zope Product for displaying IMAP mailbox contents. """ index_html = DocumentTemplate.HTMLFile("zIMAP1.dtml") manage_addzIMAPForm = Globals.HTMLFile('add_zIMAP', globals()) meta_type = 'zIMAP (webmail)' def __init__(self, host): self.host = host self.product_root = '.' class email: def connect(self, user, passw): self.user = user self.passw = passw self.M = imaplib.IMAP4(self.host) self.M.login(self.user, self.passw) self.user_dir = zimap.product_root+'/spool/'+self.user email.makefiles(self) ...

RE: [Zope] Help wanted on Zope ZClasses/DTML please.

Thanks for the e-mail Seb. I am afraid I am still having problems here, so I will show my code again, and hopefully you or someone else will be able to help. To recap : I am creating a news page and an interface to edit it using two custom ZClasses, Article and Page. A Page object contains several Articles. The following code is from a script that allows the user to delete an Article from the Page. This method belongs to the Page class, so we are currently in the scope of the Page. This script is supplied with the title of a news article to be deleted, it should then delete the Article from the Page and report back. <dtml-var standard_header>  <dtml-call "REQUEST.set('id_to_delete','NULL')">  <dtml-let the_match="REQUEST['article_to_delete']">  <dtml-in objectValues> <dtml-with sequence-item> <dtml-with propertysheets> <dtml-with UAArticleClassPropertySheet>  <dtml-if expr="article_title==the_match"> <dtml-call "REQUEST.set('id_to_delete',title_or_id)">  </dtml-if> </dtml-with></dtml-with>  <dtml-unless expr="REQUEST['id_to_delete']=='NULL'"> <dtml-let the_id="REQUEST['id_to_delete']">  <dtml-call "manage_delObjects(the_id)"> </dtml-let> </dtml-unless> </dtml-in>  <dtml-if expr="REQUEST['id_to_delete']=='NULL'"> <h2>Article not found</h2> <P>Could not find the article to delete.</P><P><A HREF=edit>Return to maintenance page</A></P> <dtml-else> <h2>Article not deleted</h2> <P>Deleted article '&dtml-the_match;' (id='&dtml-the_id;').</P><P><A HREF=edit>Return to maintenance page</A></P> </dtml-if> </dtml-let> <dtml-var standard_footer>  Basically I think I am somehow passing the wrong parameters to manage_delObjects The line <dtml-call "manage_delObjects(the_id)"> causes an error 'loop over non-sequence' This made me think that the argument has to be a sequence so I tried <dtml-call "manage_delObjects('the_id')"> but this fails because as you say it looks for an object called the_id and I need to pass in the value of the_id not the name of it. Ideally I want to say <dtml-call "manage_delObjects(REQUEST['id_to_delete'])"> but again this fails to find the object. Any ideas?

problems with Openticket in Zope

Hello, I have just installed the Openticket, ticketing system in Zope, but am having some troubles. I can log into it as an ACL user and add a new client to it, but when I try and create a new ticket, I get an error of: Zope Error Zope has encountered an error while publishing this resource.

time.sleep() in dtml
by Martin Winkler 06 Nov '00

06 Nov '00

Hello all, some python functions work in dtml, mostly mathematical ones. But what I do need at the moment is the "time.sleep(x)" function to prevent an immediate reply to a request of the users. I tried <dtml-var "_.time.sleep(1)"> and <dtml-var "_.sleep(1)">, but Zope returned an "Attribute error". Any ideas? Or do I have to create a special python method for this? (I'm not used to python until now...) Martin

Mirroring Zope sites
by Christopher J. Kucera 06 Nov '00

06 Nov '00

Hello, I'd like to be able to take a "snapshot" of a Zope site (probably using the recursive "wget") so that it can be served from Apache alone. I'm running into problems coping with files named "x_html" (most notably "index_html") . . . Apache serves up the files as plaintext, so you just get the HTML in your browser window. I've been messing around with srm.conf in my Apache configuration to try and accept "_html" as a valid extention for "text/html" files, but to no avail. Has anyone managed to get Apache to serve "_html" as text/html? Thanks much! -CJ

There are three of us (ranging from novice to pretty experienced) here that were planning to print out copies of PDF and go over them at home, none of us has the time to sit at work and read/review the whole thing on a web browser.
