How do I integrate zope with apache
by Mosquito 05 May '03

05 May '03

Hey there, I'm using linux 8.0 with KDE Desktop. I've got zope running on a medusa server at the moment, the one it came with. I've also got an apache server running and I was wondering how I can integrate the zope interface to be used with my linux apache server. I'm a total linux nub so go easy on me . ~Mosquito

24 Dec '02

Hello all, I'm tring to execute this script: lista = [] folder = container.indice2() #indice2 is a ZCatalog for file in folder: if not file.hasProperty('codice'): lista.append(file.id) attributes=getattr(folder, file) attributes.manage_addProperty('codice', 'inserted yet', 'string') return lista I borrowed the idea from the /Examples/GuestBook/addEntry script Zope prompts me for a user name and passwd, I type my usual account data (I'm the only user and I think I have full privileges) and BAM! Zope Error Zope has encountered an error while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access in this context Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error. For more detailed information about the error, please refer to the HTML source for this page. If the error persists please contact the site maintainer. Thank you for your patience. I tried to give the script all the proxy roles I could I opened Control Panel/acl_users and gave manage property permission to managers and owners (I'm a manager user): NOTHING! Please: what's going on? Thanks anybody who will help me Bye Catonano

manage_workspace in doubt
by Edwin Martin 01 Aug '02

01 Aug '02

Hello, We have a strange problem which only occurs on certain PC's/browsers. In the Zope management screen, the left menu lists all folders. Each folder points to /folder/manage_workspace (as can be seen in the status bar). Normally, /folder/manage_workspace is redirected to /folder/manage_main, so you see the contents of the folder on the right. On some PC's, instead of /folder/manage_workspace /folder/index_html appears, the page as seen by a visitor, which is not wat we want. It has nothing to do with rights. When I log in at my own PC, everything works fine, but logged in on this "problem PC", I have the mentioned problem. How is this possilble? Or better: how can I solve this? Zope Version Zope 2.3.0 (source release, python 1.5.2, linux2) Python Version 1.5.2 (#0, Dec 27 2000, 13:59:38) [GCC 2.95.2 20000220 (Debian GNU/Linux)] uname -a Linux northshore 2.2.19 #1 Thu Nov 1 19:52:06 EST 2001 i686 unknown Thanks a lot, Edwin.

Argument passing and DTMLFile methods
by Terry Hancock 02 Jul '02

02 Jul '02

Hi all, First of all, thanks to Dieter Maurer, Charles Riemann, Michel Bencur, and Joachim Werner for help on the last couple of headaches on this project! I am getting really close to releasing this sucker, but ... ;-) Next up is how to properly pass implicit arguments to a class-method created by DTMLFile. This probably requires some explanation, though ... I'm converting a prototype of the product which I developed through the web. The presentation layer is fairly large. In it, I have a few instances of explicit DTMLMethod calls, like this: <dtml-var expr="mydtmlmethod(_.None, _, explicitarg=explicitval)"> This syntax is based on the note in the back of the Zope Book on the equivalent explicit call to a DTMLMethod. E.g., it claims that: <dtml-var expr="mydtmlmethod(_.None, _)"> is equivalent to <dtml-var mydtmlmethod> And, in the "through-the-web" prototype, this is apparently true. (That is, I have verified it experimentally). However, I am now trying to make the prototype into a product, and I want these DTML methods to act similarly to their Python method counterparts (NOT python scripts -- I have converted the scripts to product class methods, which become object methods when an instance of the object is created in Zope). So far, I've used SQL(), ImageFile(), and DTMLFile() to successfully convert ZSQL methods, images, and DTML methods over to the same sort of usage as I have with Python: from Globals import ImageFile from Globals import DTMLFile from Products.ZSQLMethods.SQL import SQL dbc = database_connection_object # Defined elsewhere class MyClass(Folder): meta_type = "my_class" def python_method(self, ...): #... python code adapted from python script ... # container/context converted to self, etc. # Naturally, this works just fine, as this # this is the stuff that's well-documented pass zsql_method = SQL('zsql_method', '', dbc, args, zsql_code) # Works perfectly dtml_method = DTMLFile('dtml/mydtmlmethod', globals(), document_id='mydtmlmethod') # Works great for implicit DTML usages. Variables, # acquisition, etc, all seem to work. image_data = ImageFile('www/myimage', globals()) # A little weird, because this is the actual # image data, not the Zope image object, but # still very usable. Basically, I can't # use "tag" or "absolute_url", but I can # access it via a URL. I wasn't certain this would work, since this is different from containing these objects within the folder (which can be done either by manage_addMyClass() or MyClass.__init__()). However, so far, it works pretty well -- DTML methods are able to find each other and include subsets, pass implicit variables, etc. They can be accessed by URL: MyClassInstance/dtml_method and acquisition works on them as expected. They exist for all instances of the object, and if the methods are altered, I only have to restart Zope to propagate the change to all instances. (I.e. I don't have to delete and re-add the instances). Furthermore, they are hidden from the management interface, and are thus "read-only". Great! This is all exactly what I want -- I'm freezing the prototype into a fixed product. Changes now have to be made to the product source code to take effect. This greatly reduces the hazard of accidently screwing up the product when you're trying to administrate it. The idea is that only objects which the administrator would need to alter are made available through the web. In short, they have all the properties of ordinary python class methods. So I'm not sure if this meets "best practice standards", but it seems like a very natural solution. I was beginning to be really happy about how smooth this was all going -- I could even get the correct context in included DTML methods. "Wow!" I thought, "this Zope thing is really coming together..." (and "I might actually make that July 1st date") EXCEPT... :-( This only works if I use *implicit* dtml-var substitutions, like: <dtml-var mydtml_submethod> If I try to use the explicit form mentioned above, <dtml-var expr="mydtml_submethod(_.None, _)"> I lose my context! I can see variables passed by keywords, but not the implicit ones. They were visible in the implicit form, but not the explicit one. Ack! Ironic, isn't it? You'd think I might have to be *more* explicit in this situation. My guess is that I've somehow chosen the wrong thing to pass to this method (perhaps "_" doesn't mean anything in this context?). Presumeably, Zope is doing the right thing for implicit references, but I can't figure out what that is. (This is *after* "reading the source". Some of the source is quite readable, but the DTML publishing parts are pretty hairy stuff!). For one thing, I'm not exactly sure what the difference is between my DTMLFile object and a DTML Method or DTML Document (it seems like it can't actually be either of those, but something related). I have the frustrating feeling that a simple answer exists for this, but that I'm just not seeing it, so I'm hoping this will seem obvious to somebody. If there's no other way around it, I can probably work-around this with dtml-let and passing all variables implicitly, or by sticking huge lists of variables in as keywords, but these are ugly solutions, and it seems like they ought to be unnecessary. Thanks in advance for any ideas. We *are* very close to release if this conversion process can be made to work (the prototype, while basically working, is not up to production use for a lot of reasons -- we think it will significantly benefit from being converted into a Product). I suspect "July 1st" is out the question at this point, but maybe *next* Monday at this rate. ;-D I have some screenshots of my prototype version on our website, for the curious: http://www.anansispaceworks.com/Columns/News/A.2002.05.20 http://www.anansispaceworks.net/NaryaInfo/naryaintro.html Naturally, Narya will be open source (GPL), but I do feel it should have at least minimal functionality before trying to release it.

ZODB and ZCatalog related questions
by Thierry Florac 01 Jul '02

01 Jul '02

Hi... A few little questions about ZODB and ZCatalog... 1. I have a new Zope database (= 2.5 Mo). After adding a single PDF file of 3.5 Mo, the database is nearly 10 Mo huge !! Is required space into ZODB "reserved" by big blocks, or may the ZODB's size increase twice as the size of files which are stored into it ?? 2. After adding a few PDF files of nearly 3 Mo, stored as "ExternalFiles" (which means that only metadatas are stored into ZODB), and indexing them into a ZCatalog with TextIndexNG (my ExternalFiles provide a PrincipiaSearchSource method with the help of "pdftotext"), the size of the ZODB is 19 Mo. Does it means that full text indexing is using as much space as the document itself (but I'm starting with an empty ZCatalog) ?? 3. I'd like my products instances to be indexed automatically, as soon as they are created or modified. But as indexing seems to be quite long with big files, is it possible to index these documents in the background, so that the user does not have to wait until indexation is finished... 4. Does anyone have any experience with ZODB files bigger than 2 Giga-bytes on Linux. If so, how long does it take to pack ?? Thanks, Thierry -- Linux every day, keeps Dr Watson away... http://gpc.tuxfamily.org -- http://www.ulthar.net
