sessions in zope
by Leticia Larrosa 14 Mar '05

14 Mar '05

Hi all: I want to create user sessions in zope with credentials taken from an authentication form and data about the user taken from a PostgreSQL database. I know that Zope2.5 and later bring with something to do this like CoreSessionTracking, and exist some extra products like: SQLSession, HappySession, FSSession (I don't know any else) In any case, Where I find any documentation about how use any of them in zope with ZPT? and which one use?. I review in the zope.org page the how-tos, the articles, the books, but i don't found nothing. If anybody can guide me to the research, or have any opinion about which one use (the most important issue) and how, I will appreciate. thanks in advance

receive a message whenever there is an update in a plone site through a pop-up/mail
by Karthikeyan palani 14 Mar '05

14 Mar '05

Hi, I am developing a content management system based on plone.I have a requirement which is, " whenever an update occurs in the plone site ,a message containing the place of update should be sent to all the members of the site." I have got two ideas,i don't know whether it works 1>to query the Data.fs and retrieve data( i.e the object which has been updated) from it and send it to all the members. 2>go to ZMI and in the portal_skins/plone_form_scripts/ go to content_status_modify(handles the workflow transitions of objects) and include a code over here such that the objects which have been updated should be found and a message should be sent to all the members. Now,my question is whether if any of the above can be done(i.e is it possible to query Data.fs while the site is up) or is there any other solution for my requirement?If anyone knows an answer to this please give me an idea on how to do this and if possible send me a code example. Thanks and Regards, Karthikeyan.P L.

Hi, I plan to develop a product that make use of external database (MySQL). I tried to get some reference on this in internet, but to no avail. How can i do this?. I understand that with python script or dtml we need to create database connection object, and zsql method. But how do we do it from product class?. If i can get some point of reference from the net, it would be good. Thanks. __________________________________ Do you Yahoo!? Yahoo!

Zope 2.7.4 - ZClass Permissions Change?
by Jake 13 Mar '05

13 Mar '05

I have a few ZClass products that no longer allow me to add new objects and it is new since Zope2.7b4. It is happening with a few products like SimpleURL and KnowledgeKit and I am getting errors like: "Unauthorized: You are not allowed to access 'blah' in this context" It could be a method, a list or ZopeTime. I looked over the release files and can't find anything on this specifically. Jake ____________________ http://www.ZopeZone.com "Zoping for the rest of us"

I have used it successfully under Windows. Don't know if my knowledge would be any good for Linux. What exactly seems to be the problem? Etienne

Installing Photo and Photo Folder 1.2.4 Under Plone 2.0.4 on Mac OS 10.3.8
by Tom Harris 13 Mar '05

13 Mar '05

Hi Everyone, I'm running a Plone 2.0.4 site under Mac OS 10.3.8 and am having trouble getting it to notice when I drop the Photo and Photo Folder 1.2.4 product folder into the Products folder of the site in question (of course I restart the server every time). I don't know my way around the ZMI terribly well but looking at Plone's product install area it doesn't show up (I didn't expect it to since it's not written specifically for Plone, but the Plone easy install is great) but neither can I find it in the Products listing under the control panel in the ZMI. It doesn't even show up as broken in there. Am I missing an install step? I'm pretty sure I followed the install instructions, which actually only said to drop it in the Products directory (I do modify ownership and permissions after putting it there). Of course I am restarting Plone/Zope each time. Another note, I do have the CMSPhoto and CMSPhotoFolder products installed and working so I wonder if there is a conflict. I did remove them once for purposes of testing this, but I'm not sure I removed EVERYTHING they might have done to the site. This product actually does a lot of what I was wanting to do with photos on my site so I'd really love to get it working. The next question will be how to convert all my photos and preserve the metadata which reflects a huge amount of work! Thanks much, Tom Harris

soln found for two drop down
by prabuddha ray 12 Mar '05

12 Mar '05

Thanks yuan. i finally got it . I think i'll be much happier and productive with ZPTs. In the body tag define: <body tal:define="doDistrict request/districtname|nothing"> this was for 1st dropdown list ; <select name=districtname style="HEIGHT: 22px; WIDTH: 185px" onchange="user10()"> // in user10() i submit the form explicitly. <option name="selectDistrict" selected> <div tal:repeat="district container/getDistrict"> <option tal:content="district/district_name"></option> </div> </select> 2nd drop down list : <select name=username style="HEIGHT: 22px; WIDTH: 185px" tal:condition="doDistrict" <div tal:repeat="user python:context.getDistrictUser(districtname=request.form['districtname'])"> <option tal:content="user/username"></option> </div> </select> That got rid of the error. I was wondering whether in my Python script getDistricUser i could also, by default, assume that i'm passing in districtname. Then I cud just say <div tal:repeat="user here/getDistrictUser"> which is more pleasing to the eye. By saying "or nothing" when I define variable doDistrict I can then test for it later. And it evaluates to false on the first pass. So any tips.

CMF -1-5-0
by David Hassalevris 12 Mar '05

12 Mar '05

Hi list, I downloaded cmf-1-5.0.zip and installed it into Zope 2.75b1 Zope_Instance/Products directory. Afer rebooting I was surprised to see it wasn't listed as a Product so I look in Products\CMF-1.50 and there is no __init__.py. Isn't that how products are recognized? I feel I'm missing something obvious :-0 Also I'm having trouble locating CMF documentation. Any recommendations? Thanks, David
