[Help] Setting up MySQLconnection
by Richard Wesley 25 Mar '02

25 Mar '02

I am trying to set up a mySQL DB adapter in Zope. I am somewhat of a Zope and Linux newbie so I am probably doing something dumb. Here is what I have done: - Downloaded MySQL-python-0.9.0 to the Zope install dir; - tar -xzvf MySQL-python-0.9.0.tar.gz - cd MySQL-python-0.9.0 At this point I looked at the README. It requires Python 1.5.2 or higher (I think we have 2.2) and a recent MySQL (which I believe we have). I did not edit setup.py because we are running Red Hat. I then do - python setup.py build and it chugs along until it gets to the gcc _mysql.c when it gives me an error _mysql.c: In function `_mysql__fetch_row': _mysql.c: too many arguments to function `PyTuple_Resize' This looks to me like a call to the Python API and it appears that my libraries define this differently from what the code expects. Any help gratefully appreciated. - rmgw http://www.electricfish.com/hawkfish/ ---------------------------------------------------------------------------- Richard Wesley Electric Fish, Inc. hawkfish(a)electricfish.com "There's nothing intellectual about wandering around Italy in a big shirt, trying to get laid." - Rowan Atkinson, "Black Adder:Ink and Incapability"

Catalog Awareness
by Geoff Armstrong 25 Mar '02

25 Mar '02

Hi, I have a need to modify a Zope product so that at least one of it's classes becomes catalog aware. All the documentation I can find on catalog awareness refers to building ZClasses and giving them this feature; but the product I need to modify is built with external python code that resides in the "Products" directory. I understand though that it is possible for a product to be built which is a hybrid of Python code and ZClasses. So perhaps it is possible? Right now I'm having to use a workaround that changes the properties of a dtml document each time I need to catalog a new item of the product class concerned. I then re-catalog the same dtml document with the new properties; but this is taking to much of a toll on performance. Can anyone advise me on this? Thanks geoff

by Chris A. Bruce 25 Mar '02

I saw Dieter's bogus answer to attaching multiple files in mime method, but have no clue how that answers anything? http://groups.yahoo.com/group/zope/message/82157 Anyhow, has anybody got any working example of how to send all of the files in a folder as attachments using sendmail and mime? Thanks in advance, Chris

RE: [Zope] HomeSite 5 and Zope
by Schmidt, Allen J. 25 Mar '02

25 Mar '02

Where are you seeing this problem? If you mean you can't "see" the files themselves, then just right-click in the contents pane and select VIEW (I think) and select ALL FILES...it defaults to only showing Web Documents. Been using HS for years and with Zope for about 2 years and it ROCKS! And now version 5 allows search and replace on FTP files and folders...Fantastic! I have also added .dtml as an extension within the settings but don't think that was necessary. I have my own Zope toolbars so I can single-click all my favorite functions just a click away. I would be glad to offer any help in using HS for working with Zope. ALMOST completely eliminates the use of the ZMI for working with Zope. Have fun!

Here you would add the ftp port (8021 by default; see you z2.py) user name and password (that you have created as a Zope acl_user account. The limit, which I have never seen a solution to, is how to get HomeSite to see zope objects with no extensions. Adding .htm to each zope object you want to edit will do the trick for allowing edits, but there are some negative scripting implications for doing that. I'm looking forward to Macromedia fixing this someday in Dreamweaver and Homesite. No idea if they will. It does not seem to be a priority for them. Have you tried UltraEdit or the newest version of Textpad. I have yet to see if these programs have the above limitations.

Using FTP to connect to Zope server from (g)VIM
by Phil Harris 25 Mar '02

25 Mar '02

Hi all, My intellect was piqued recently by a discussion on the list about editors for Zope etc. I remember some people saynig that VIM was good, to which my response was, 'Yeah but there's no FTP built in'. Someone then responded with a few scripts to do it. Well I thought they were a bit cumbersome, so I wrote my own. ftpopen.py and ftpsave.py. If you have a VIM executable with Python support built in then these run from within VIM and allow you to open/save file from/to Zope seamlessly. (I have them on a menu in GVIM for instance) I'll put the files up on my Zope Members bit (http://www.zope.org/Members/philh) along with a few instructions. If anybody can think of any enhancements then please let me know and I'll see if I can work them in. I hope these will be useful to someone. See ya Phil phil.harris(a)zope.co.uk

Transient Object Container/Session Data Manager
by Michael Fox 25 Mar '02

Hi *, Does anyone know of any documentation for use of these objects with Zope 2.5.x? I'm having issues with sessions timing out, and need some way of redirecting the user once their session has timed out. in DTML, testing if "REQUEST.SESSION" exists doesn't quiet work... resulting in a KeyError. Regards, Michael

Concurrency/Atomicity in ZSQL/ZOracleDA ?
by Renaud Guerin 25 Mar '02

25 Mar '02

Hello, I have a probably simple question, but got different opinions on the matter, and I'm seriously in need of a quick answer. I need to make a ZSQL method that inserts data in a table this way: 1) first, generate a new ID with something like SELECT MAX(ID)+1 AS my_id FROM ... (using a sequence is not an option for me for various reasons) 2) then, INSERT with the ID previously generated ( is INSERT INTO ... VALUES (<dtml-var my_id>.... the right way to do this ?) 3) display my_id to the user for future reference. First, I'm not sure how to do 3) : how do I pass my_id back to the original DTML document (which calls the ZSQL method with dtml-call) ? Also (main question), is there something particular to do to ensure SELECT+INSERT is done in an atomic way that avoids concurrency problems ? I know Zope starts and ends transactions with HTTP requests, but I'm not sure this implies the kind of read locking I need. thanks a lot! PS: please cc any answers.

Re: [Zope3-dev] a note on groups and roles

Adding a group and associating permissions with the group to the > place represented by the root container or to an individual leaf object > twelve levels deep actually becomes the same operation. I dont' understand this part at all. Either it is possible to have different permissions in different places, or it's not. With a roles system, this is done by giving people roles locally. If you scrap the roles, then it means you either have to assign people to groups locally, ie local groups, or you must be able to set the permissions locally, ie local permissions. So your suggestion doesn't obviate the need for local roles, it just creates a need for something other that is local, since you don't have any roles at all, and therefore obviously can't have local roles. :-) I any case: There are a lot of permissions in a Zope system. When adding some more products, you get even more permissions. Roles are a grouping of permissions, and is neccessary to make the permission system mangeable. If you each time you need to locally change the permission settings for a group of a person have to wade through 30-40 permissions and remember exactly what each of them does, you will only end up with giving most people the rights to do almost everything. The only problem with the Roles system is that people over and over again mistake it for usergroups, since they are expecting usergroups. This can be fixed by having some type of usergroups in addition to the roles. Then people won't think roles are usergroups, read the documentation and see the light. Besides, some type of user grouping is necessary. Also, the Anonymous and Authorized roles should be removed, because these are not proper roles, and may add to the confusion of roles and groups. Anonymous should be a built-in and non-removable principal. If it helps to clear up the roles concept, maybe some other roles like "Author", "Viewer" or "Member" should be created by default. But "Authorized" is a state, not a role. > FWIW, relatedly, I don't understand the use of the term "principal" > instead of "user" for the "entity with credentials" in Zope 3. Neither do I. For me "principal" means "headmaster". :-)
