Sessions & DTML Execution
by Justin Dunsworth 08 Apr '15

08 Apr '15

Hello, I am running into an issue that I can't quite figure out. I'm trying to leverage storing data within sessions then setting a variable in the header of my page to the session variable (for ease of calling) where I can then use it throughout the rest of my document. Here's the way it goes: <dtml-if "REQUEST.SESSION.get('testVarDict')"> <dtml-call "REQUEST.set('testVarDict',REQUEST.SESSION.get('vx9member'))"> <dtml-else> <dtml-call "RESPONSE.redirect(BASE1+'/login')"> </dtml-if> <dtml-var testVarDict> Here I am wanting to redirect to login should testVarDict not be set. Instead it seems like Zope is still wanting to execute the rest of the page prior to redirecting so this will throw a NameError for testVarDict should the session data not be set. I then found out that I can change the dtml-call to a dtml-return for the redirect and it will stop executing the dtml and redirect. This is all fine but if I have another page I'm going to call that uses the header like so: <dtml-var headerDoc> <dtml-var testVarDict> <dtml-var footerDoc> This then will throw the same NameError regardless of the dtml-return redirect in the header. I can get around this by placing the same checks in the top of every.single.page that I want to utilize testVarDict variable but that's too cumbersome. I then tried to make a script that would check the same thing and then redirect but it doesn't seem to work at all - for fun here's the python script: if context.REQUEST.SESSION.get('testVarDict'): context.REQUEST.set('vx9member',context.REQUEST.SESSION.get('testVarDict')) else: return context.REQUEST.RESPONSE.redirect('/login') I've also tried just the context.REQUEST.RESPONSE.redirect without the return but it doesn't seem to work and I suspect it's because python return is not the same as dtml-return. If anyone could assist or show me a different way then I would greatly appreciate it. Thanks, J

Start up failing with ZopeCtlOptions instance has no attribute 'transcript'
by Sebastian Tänzer 02 Apr '15

02 Apr '15

Hello all, latest Zope2 releases (2.13.23.dev0) seem top have a bug in Zope2/Startup/zopectl.py and zdaemon/zdctl.py leading to this error on zopectl start (zopectl fg works fine): Traceback (most recent call last): File "/opt/python/zope2/bin/zopectl", line 9, in <module> load_entry_point('Zope2==2.13.23.dev0', 'console_scripts', 'zopectl')() File "/opt/python/zope2/lib/python2.7/site-packages/Zope2/Startup/zopectl.py", line 488, in run exitstatus = main() File "/opt/python/zope2/lib/python2.7/site-packages/Zope2/Startup/zopectl.py", line 447, in main c.onecmd(" ".join(options.args)) File "/opt/python/2.7.9/lib/python2.7/cmd.py", line 221, in onecmd return func(arg) File "/opt/python/zope2/lib/python2.7/site-packages/Zope2/Startup/zopectl.py", line 241, in do_start ZDCmd.do_start(self, arg) File "/opt/python/zope2/lib/python2.7/site-packages/zdaemon/zdctl.py", line 305, in do_start args += self._get_override("-t", "transcript") File "/opt/python/zope2/lib/python2.7/site-packages/Zope2/Startup/zopectl.py", line 223, in _get_override value = getattr(self.options, name) AttributeError: ZopeCtlOptions instance has no attribute 'transcript' I repeated my setup multiple times and was able to reproduce this every time with every setup, so I don't think this is a configuration error on my side (yet if it is please tell me what might be wrong). Zope2 was installed using a simple pip install Zope2. Imho this bug comes up as in Startup/zopectl.py" the ZopeCtlOptions class is beeing emulated but so. missed the transcript attribute (as before this happend with the startup-time attribute, too). I created a patch that's attached to this mail and should be run inside the virtualenv python dir (i.e. where bin, include, lib etc. reside): patch -p0 < patch-zope2-startup.diff Maybe someone could confirm that this bug exists and this fixes it?

Zopache Demo
by Christopher Lozinski 01 Apr '15

01 Apr '15

Zopache is a through-the-web Javascript Development environment built on top of Python, ZODB, ZTK, and Grok. Zopache was used to build zopache.com You can see a demo of the gorgeous HTML editor here: http://www.zopache.com/demo We are so used to thinking of Zope as open source software. That business model is not working. Furthermore most of the people in the world are not able to configure their own servers, let alone understand the Zope Component Architecture. A different approach is needed. I wish I know what is was. CHris
