Re: [Zope] acquisition problem
by Blazay Blah 04 Jun '04

Hi Chris, I am having very similar acquisition issues in Zope, ie I would like to access contents in child folders but can never get the namespace correct. I would like something like Transparent Folders, but it sounds like this is antiquated. I would definitely like to try your new solution. Thanks.

Are you comfortable writing a Zope Python Product? I am, and was looking at this same behaviour a few days ago. I have a structural change as a workaround, but to be able to override stuff on the sort of basis that Gál László was asking about... would be rather helpful. ben

Re: Largefile support error

I'm not a linux expert, but I know some old linux kernels, c libraries, and ext2 don't have large file support. Perhaps an linux kernel upgrade will solve it. You could also tried to create a file greater than 2 Gb from the unix shell: dd if=/dev/zero of=big_file_test bs=1024 count=2600000 If everything goes well, you will see a 2.5Gb file called "big_file_test". On the contrary, you will see an error, which means that your debian really doesn't support large files. Indeed you will need to upgrade. Regards, Josef

Anyone have a recommendation on a reasonable video server to use in conjunction with Zope?

RevisionManager
by Boswell, Richard 04 Jun '04

04 Jun '04

Has anyone gotten RevisionManager to work with Zope-2.6.4? I am attempting to setup RevisionManager and CVS, but I am receiving an error message when I attempt the initial import of documents. It gives me a cvs [import aborted]: /var/RevisionManager/CVSROOT: No such file or directory error message when I attempt the initial import. I have setup CVSROOT to point at /var/RevisionManager and there is a CVSROOT directory. Richard Boswell Network Security Engineer Symbion Healthcare Work - 615.234.8912 Cell - 615.445.5944

Permission problem creating a wrapper class for custom search
by Francis Kelly 03 Jun '04

03 Jun '04

I'm trying to create custom search module that will fit into the out-of-the-box Plone search functionality. I'm running into a permissions problem (which I believe is a Zope and not Plone issue). I get back a list of dictionary objects from my search method and I want to wrap those up in an object akin to the AbstractCatalogBrains object used by Zope. But when I use my own SearchWrapper class, an Unauthorized exception is raised telling me I don't have the right to use the methods of my SearchWrapper class. To summarize: (1) a python script calls a search method that returns a list of dictionaries (2) the list of dictionaries gets converted into a list of SearchWrapper objects (3) the search.pt (in Plone) tries to display the search results, but when it tries to use the methods/attributes of the SearchWrapper class (e.g. Title, getId(), getURL(), etc) it raises an Unauthorized exception. I've tried different strategies: defining SearchWrapper as a Product as well as putting it in the Extensions directory. Neither seemed to work. I guess my basic question is: how do I tell Zope that my SearchWrapper class is safe in the same way that the AbstractCatalogBrains is safe, since Zope is ok using the methods and attributes of search when it returns a list of ACB objects? (I'll just add: I did try to sub-clas AbstractCatalogBrains, but I ran into problems trying to define new attributes. I'm assuming ACB is defined (using __slots__ or something), such that you can't define new attributes on sub-classes. I'm quite new to Python and didn't have a lot of success figuring that one out.) Thanks in advance for your help! Francis

The default directory can get changed by other code. You should never rely on it. The OP's problem was that he did what you said and couldn't find the target file. Cheers, Tom P

thanks i'll try to make this real, but i'm new in this i for the things that i read i thought that i can use the command "open" easily, but i see that is not possible..

Only because of the absolute path. Now, you could just write that path into your Python code, but the way I illustrated allows you to move your code to other directories and still find the right path. That is a big advantage. > I have another question, which is the BASEPATH, the path to > the pakage > YourProject?? It is the absolute path to the location of the directory where you put the code you want to run. The __init__.py file will know where it is located, and so we use that knowledge. > && where goes the last part of code that you show to me?? in > the init.py or > in a external method in the directory Extensions?? > sorry for these questions... first time in zope.. > The very last lines of code belong in the file in which you put the code for your external method. That file will be in the Zope\Extensions directory. Cheers, Tom P
