Date calculations in Zope
by Greg McCall 15 Dec '02

15 Dec '02

Hi I am having trouble performing date calculations in Zope. I have a variable called dob which returns a date of birth from MySQL Ie. Date of Birth=<dtml-var dob> works fine I would like to be able to list the current age in years and months I can get a years calculation with the following line Age in years = <dtml-var expr="ZopeTime().year()-dob.year()"> A similar line works using months Months = <dtml-var expr="ZopeTime().month()-dob.month()"> I don't know how to do the month above when say you are in month 1 and you subtract month 12 Also, how can the results be placed in a form. Eg <INPUT TYPE="TEXT" NAME="AgeYears" value="0"> <INPUT TYPE="TEXT" NAME="AgeMonths" value="0"> I tried putting the above dtml-var code in the value attributes without success. Thanks Greg

I also have IE 6.0 sp1, and Win 2000 pro sp3, both with all security patches. In trying to figure out how to configure a different port I set the port to "81" which works fine. I did not try 80 so do not know if it is a problem for me also and since 81 works fine I'm going to leave it. So maybe it is just port 80 that has a problem, try 81 and see what happens.

Left navigation bar; how to implement one.
by Hans Deragon 15 Dec '02

15 Dec '02

Greetings. I searched in many places, but I could not find an example on how to create a left navigation bar with Zope. I might have some ideas, but I would like to hear from you oldies (as opposed to newbies) the most efficient way to create one. Off course, the left navigation bar should show up on each web page of the site, it would expand as the user goes in deeper on the site and you would only need to write it once and use it on all of the web pages. I am a newbie to Zope, but not in html or python. Sincerely, Hans Deragon

The other way round: disallow for people except for a special role (just create one, preferably in the root of your app) And give your methods "proxy roles" for exactly this role.

And compared to Java its even much simpler. (You should have an eyeball at the appropriate section in the zope-book) Roughly you just go to Control_Panel/Products, create a new product (just like a folder) and then create a ZClass with "Factory Functions". Derive your Class from ZPT or whatever you want to manage. Go to the methods tab and just add your management Templates and methods. This turns out to be pretty easy. One tipp from me: while ZMI creates factory function in DTML, you can easy replace these with a python script, which gives you better readability: request = container.REQUEST response = request.RESPONSE # create the new object object=container.FunctionElement.createInObjectManager('your_meta_type', request) # edit propertys of the new object object.propertysheets.main.manage_editProperties({'title':request.title}) # mimify the default behavior - redirect if called from ZMI du=request.get('DestinationURL',None) if du: response.redirect(du+'/manage_workspace') else: response.redirect(request.URL2+'/manage_workspace') > languages like Java.

RE: [Zope] Zope 2.6 and ZEO 2
by Vladimir Petrov 14 Dec '02

14 Dec '02

Actually, the problem was with permissions... Zope and ZEO MUST be compiled as nonpriviledged user (ie zope) and started as such user. It wont help if you start z2 with -u argument, you have to use something like setuidgid or to start zope and ZEO from actual account. The funny thing is if you started Zope (and respawn proces later on as zope) and ZEO as a root, everything just goes fine (nothing in a log) but it's not working. Only by strace (and a lot of stack infos) we noticed that there was a permission problem. Such thing will be nice to be noticed in docs (maybe I overviewed something). At the end I got Z2.6&ZEO2.0 up and running, and it's working like charm. I'll write article about procedure which MUST be followed to get this up&running...

zope mailing-list digests
by Andrew Durdin 13 Dec '02

13 Dec '02

This is possibly a bit off-topic, but I'm finding that most of the daily digest messages I get on this list are truncated, and missing most of the individual messages. Has anyone else had this problem? If so, what did you do about it? Andrew

Problem starting Zope 2.6

I've compiled Zope 2.6 from source (RH 7.2) and I can't get it to run. I used python 2.1.3 to compile it. Zdaemon will spawn processes but those processes will send signal 11.

Configuring Zope's python for ssl
by Kevin Carlson 13 Dec '02

13 Dec '02

I need to write an external script that access pages via https. When I try this using an HTTPSConnection object I get an error stating that ssl is not available. I noticed in the socket.py file that the ssl module is available "if configured". I have found threads that show me how to configure python for ssl but I'm curious if the python that comes with Zope can be configured similarly. Any ideas? Thanks, Kevin
