Asynchronous triggering of events
by Brian Sullivan 22 Oct '10

22 Oct '10

I am back working with Zope 2.9.1 (yes I know it is long in the tooth but I am trying to avoid adding the pain of upgrading, having products fail and all the usually comes with upgrading if I can). I am looking for a strategy to schedule and carry out tasks at periodic future dates. I had a look at Xron (http://www.zope.org/Members/lstaffor/Xron/) but it either doesn't seem to work with 2.9.1 (or I can't get it to work). I install it in the products directory but it doesn't show up in the product directory when Zope restarts and naturally none of the objects it is supposed to supply can be added. I haven't investigated what the problem is (and am not even totally sure how to go about it). Is there something isn't obvious that I might be missing? Barring getting it to work are there any other alternatives?

Persist password in CookieCrumbler
by Brian Sullivan 22 Oct '10

22 Oct '10

Can I persist the password using CookieCrumbler (in addition to the user name)? Has anybody made this modification and can supply the modified product or code. I made a stab at it but obviously my level of understanding is not up to snuff 'cause I can't get it to work. What are the implications/problems that might result from doing this?

Plone the new Zope?
by Brian Sullivan 20 Oct '10

20 Oct '10

I haven't done any Zope work for quite a while and have just restarted out of necessity. Things seem to have changed in the last few years. I get the impression from the age of the Zope installs, the state of disrepair and link rot of the zope.org site that Zope is in its final death throes as an independent entity ? I tried to look for an independent version of Plone that I can install on an existing Zope = the only install I could find is a complete installer including Zope. Is Plone the new Zope?

How to setStatus(301) for zException Redirect
by Norbert Marrale 08 Oct '10

08 Oct '10

Using Zope 2.10.8 I'd like to let an access rule trigger a 301 'moved permanently' redirect. I created an external method to raise the exception, which almost does the trick except for the fact that it generates a 302 Moved Temporarily status code. from zExceptions import Redirect def myDispatcher(self, url): raise Redirect(url) Tried request.setStatus(301) both in my access rule and the external method, but this effectively disables the redirect. Also tried modifying my external method similar to request.response.redirect() as follows. Still no luck. from zExceptions import Redirect def myDispatcher(self, url, status, lock): raise Redirect(url, status, lock) I finally traced it to HTTPResponse.py starting around line 763-790 the 302 status seems to be hardcoded. How would I go about changing this? I'd rather not hack directly in the Zope code... self.setStatus(t) if self.status >= 300 and self.status < 400: if isinstance(v, str) and absuri_match(v) is not None: if self.status == 300: self.setStatus(302) self.setHeader('location', v) tb = None # just one path covered return self elif isinstance(v, Redirect): # death to string exceptions! if self.status == 300: self.setStatus(302) self.setHeader('location', v.args[0]) self.setBody('') tb = None return self else: try: l, b = v if (isinstance(l, str) and absuri_match(l) is not None): if self.status == 300: self.setStatus(302) self.setHeader('location', l) self.setBody(b) tb = None # one more patch covered return self except: pass # tb is not cleared in this case Norbert

ConFoo 2011 Call for Speakers
by Yannick Gingras 07 Oct '10

07 Oct '10

Greetings Zopers, We, Montréal-Python, are the coordinators of the Python track at ConFoo 2011 and we are very proud to announce our call for speakers. PHP-Québec, Montréal-Python, Montreal.rb, W3Qc, and OWASP Montréal are organizing the first edition of the ConFoo conference, which will be held in Montréal on March 9th through 11th at the Hilton Bonaventure Hotel. With over 500 expected attendees, ConFoo is one of the largest Web development conference in North America. ConFoo is about the Web, but it's also about showcasing the strengths of different technologies. Do you think that Python beats all the other languages out there for Web development? Do you think that Zope knocks Django's socks off? Come and tell us why! Sessions are one hour long and you can present in French or in English, which ever your prefer. Submissions are due for November 26; for more details, visit the ConFoo website: http://confoo.ca/en/call-for-papers By the way, we are perfectly aware that there is a slight clash with PyCon. You should not worry about that since all Python talks will happen before Friday, giving you plenty of time for the commute towards Atlanta. Share the word! -- Yannick Gingras http://montrealpython.org -- lead organizer

Need some newbie tal help
by Mark Phillips 05 Oct '10

05 Oct '10

I have a table and I am putting data into the cells using tal. I want to bold the data under a certain condition. I tried this, but it didn't work: <td tal:content="string:${player/name}"><b tal:condition="python:str(player['name']) == 'Team'">name</b></td> The data (player/name) appears correctly, but when player/name='Team', the text is not bold. After some reading, I believe what is happening is that the tal:content tag is replacing everything between the <td> and the </td> tags. Is this correct? I tried this, and no bold either: <td tal:content="string:${player/GP}"><b>GP</b></td> which supports my hypothesis about the tal:content tag. How do I add some "conditional bold effect" in my table data? Mark

Hi, I need the old timers to help with a zope dtml-try/dtml-except conditions. I am using Zope 2.6.1. My problem is as follows: <dtml-if expr="fluency_temp<>''"> fluency - <dtml-var fluency_temp>** <dtml-call "REQUEST.set('fluency_test', fluency_temp)"> <dtml-call "string_to_int(fluency_test ,REQUEST)"> <dtml-try> <dtml-call "REQUEST.set('fluency', y)"> <dtml-except ValueError> <dtml-call "REQUEST.set('name_error', 'error')"> <dtml-if expr="name_error=='error'"> Invalid Number entered <a href="../prek_4_dra_scoring_system/display_student "> Click here to go back</a> <dtml-else> <dtml-call "REQUEST.set('student_full_name', student_full_name)"> <dtml-call "REQUEST.set('dra', dra_temp)"> <dtml-call "REQUEST.set('date_scored', ZopeTime())"> <dtml-call "REQUEST.set('fluency', fluency)"> <dtml-call expr="update_dra_edl_score_1_4_record_eng(REQUEST)"> </dtml-if> </dtml-try> </dtml-if> </dtml-in> </dtml-if> I will see an error if I enter a letter and not a number - Exception Type ValueError Exception Value invalid literal for int(): a I have trapped for errors like this before using this method but no luck this time. Thanks in advance, Larry McDonnell
