Pointers in zope ??? object1 --> object2
by NABETH Thierry 20 Jun '00

20 Jun '00

Hello, I am trying to figure out how I can find a way to implement pointers in Zope. In other words, I would like to be able that the content of an attribute reference another object. object1 --> object2 and say for instance: object1.aaa := object2 and then get this object with object1.aaa I have spent a lot of time, looking for instance how the name space work. I had thought for instance that I would create a string field in which I would store the id of the other object. But the problem, is that I do know how to get the object from this id in the system, unless it belongs to the same namespace. I had also thought that I could store in this field, the url of the object. >From this url, I would then be able to get the object. (since you can call an kind of method by <url-of-the-object>/<mymethod>) But it didn't work. For instance <dtml-with <url-of-the-object>> .... </dtml-with> raise an error. eventually, you can imagine that you can access an object specified in a absulute way by using """"plenty"""" of dtml-with. for instance for accessing the /root/b/c/d/e object, we would use <dtml-with root> <dtml-with b> <dtml-with c> <dtml-with d> <dtml-with e> </dtml-with> </dtml-with> </dtml-with> </dtml-with> </dtml-with> But really this is too complicate, and really can not be implemented. Do you know an answer to this question. I can not believe that this is not possible, given the OO approach of zope, and the fact that it relies on python.

PoPy Licence
by Eric Bianchi 20 Jun '00

20 Jun '00

Dear PoPy and zpopyda users, there has been a lot of discussion lately concerning the GPL issue of PoPy on zope mailing list, python mailing list and even in the Mixadlive itself. We have been thinking a lot since there. On one hand, we are very concerned about using and developing free software available for the community, on the other hand, we want to provide the best product for our user and give them the availability to enjoy popy as much as we do without having licence issue, that's free software... We have developed PoPy to work faster and cleaner and since we are using it, our work get easier than ever. That's why we have chosen to modify licences of PoPy and zpopyda and put them under the LGPL licence. We hope you'll enjoy that for comments and questions please use our mailing list : popy-user(a)lists.mixadlive.com Regards the PoPy team

comercial products using zope
by Terry Kerr 20 Jun '00

20 Jun '00

Hi, I am researching using zope as a framework for a product that I am going develop and sell. I will develop a python product for zope. The product will not be open source, so I will only be distributing the byte code .pyc files, and not the source. However I understand that it is possible to decompyle .pyc files back to the source....although I don't know how difficult this is to do successfully. Are there any tricks that I should know about to make this any harder? Basically I want to know if anyone else has used zope for a commercial product b4, and how they did it. Is there anything in particular that I should know about. Should I just rely on a good software license to protect my code? Also...are .pyc files as platform independent as .py files? Any info appreciated. terry -- Terry Kerr (terry(a)adroit.net) Adroit Internet Solutions Pty Ltd (www.adroit.net) Phone: +613 9563 4461 Fax: +613 9563 3856 Mobile: +61 414 938 124

RE: [Zope] Embedding authentication in a Zope Website

You protect an object using permissions and roles. Once they hit an object that requires authentication, they'll be prompted to log in. For example, you might want to create a role named 'Bleah' and assign a bunch of users to that role. Then protect a folder 'Foo' by assigning the 'View' permission to the 'Bleah' role. When users navigate to 'Foo', they'll be prompted for a login. If they have the 'Bleah' role, and they enter the proper username/password combo, they'll be permitted access. If they don't have the 'Bleah' role, or if they do not enter a proper username/password combo, they'll be denied access. You may also want to check out the new Zope 2.2 release that has context-sensitive help for most of this stuff via the 'Help' button on the page. > 2) how can you seperate your userlists for your web sites > from your user > list for zope administration, especially considering you will probably > want users to be able to access multiple trees equally? You don't, a user with management privileges (e.g. the "Manager" role) is just another user.. it's just that he/she has mangement privileges while others may not. > Any advice appreciated.

Re: [Zope] TAG for file date
by CURTIS David 20 Jun '00

20 Jun '00

Greeting, Thanks Tino for your reply, but alas I am still not able to achieve what I want. Perhaps I do not understand what you are teaching. I am trying to display the date of a document in an HTML document. Here is what I tried. Step 1.) CREATE A FILE OBJECT I used the menu to create a file object. ID=GuideFile Content Type = Application/ Precondition = BLANK Step 2.) ADD CODE TO HTML FILE I tried to add <dtml-var "GuideFile.bobobase_modification_time"> But I do not get an output displayed!!! I tried to make it a paragraph, bold etc, but no luck. Although I do not get an error from Zope it does not work correctly. I am using the latest version of Zope 2.1.6. If you see where I failed, please let me know. Thank you in advance for any information. :-) >>> tino(a)wildenhain.de 06/20/00 02:52AM >>> CURTIS David wrote: > > Greetings, > > I have a database file that gets copied via a cron job at night.

DCOracle on AIX
by Friedrich, Robin K 20 Jun '00

20 Jun '00

Hi guys, I know this isn't Zope related but this list is the closest thing I know of. We are attempting to get DCOracle 1.3.0 working on our IBM AIX 4.2 platform talking to Oracle 8.1.5 and we are running into a problem. We can get things to compile into the shared object extension fine but it abruptly fails when we attempt a Connect() call. No exception, no core dump, just exits. Questions: 1) Is the code known to work on AIX/Oracle8 ? 2) If so can you give us some pointers or names of folks who have it working? 3) If not can you provide some things to try to help us track down the root cause? TIA Any help would be appreciated. Robin Friedrich Flight Operations Reinvent United Space Alliance

sql-statements in DTML-Methods....
by Marc LUDWIG 20 Jun '00

20 Jun '00

Hi. This is one of the first times I'm working with Zope and databases. Until now - if I wanted to work with a databse, i always created a Z SQL method that I called from my DTML-method via <dtml-call "add_item(param1 = ..., param2 = ..., param3 = ..., ..."> (for example) or <dtml-in get_items> ... </dtml-in> (for example) In the Z SQL method 'add_item' or 'get_items', my SQL statement are defined. My question is now: Do I have to define one Z SQL Method for every SQL statement I want to perform on my database or is it possible to define SQL-statements and database requests in my DTML-method? Am I missing something? Any idea? Thanks a lot. Regards, Marc mailto:lutschi72@gmx.net
