RE: [Zope] FIND AND REPLACE
by Schmidt, Allen J. 01 Apr '02

If you use Windows or have access to a Windows machine, go to www.macromedia.com and get the trial version of HomeSite5. Full product tryout for 30 days. Setup an FTP connection to your Zope, port 8021, and use the Find and Replace feature. Works great. Be glad to help offline if you need a quick pointer. Its pretty straightforward, though. Good luck!

CVSFile - can´t update file in sandbox
by Oliver Skiebe 01 Apr '02

01 Apr '02

hi there, i am running CVSFile 0.7 on Zope 2.5.0; when i try to update a checked out file in the sandbox with a local file (i.e. upload that file), zope keeps telling ma "... Invalid request The parameter, externalfile_content, was omitted from the request...." This only happens when uploading binary files - e.g. Images -, text files work just normal. Creating new binary files and committing them to cvs works as well... Any suggestions out there? - Thank you! - Oliver _____ To understand recursion, we first have to understand recursion.

possible bug in zope 2.4.0/2.4.3 or 2.5.x
by Ollas, Marcus 31 Mar '02

31 Mar '02

Dear sirs, i'm a software developer from germany and actually writing a web-based application. This application is based on zope, because in my opinion zope is perfect for this. I've developed this application as a python based product, the first version written in dtml was too slow. Everything has worked fine, till I wanted to develop a new feature. In my application I'm using a server-based sessions-management, which stores my object instances in a sessions-directory, which itself is stored in the ZODB. Now one of these objects has a dictionary, which stores multiple subobjects, for example the main object is a company, which has subobjects representing contact-persons in this company. Now I've written functions, which allow the user to add/change and remove contact-persons for a company. To let this work, the companies object with all the subobject is stored in the ZODB. Now the problem is, that zope seems to forget the contents of the dictionary. You can add, remove and change the subobjects, but suddenly the dictionary contains only that subobjects, which where in at the beginning. Example: The companies instance is stored into a ZODB Folder with the id "Company10". Now this instance has a property "contacts", which has a directory named "__items__". The contacts itself are represented by another object, which instances are stored in contacts.__items__. So if you call Company10, there are 3 contacts saved into __items__. Company10.contacts.__items__{1:Contact Instance at ..., 2:Contact Instance at..., 3:Contact Instance at ...} You can now add, remove and change the contacts for the company, but suddenly all changes made for the __items__ dictionary are lost. Maybe you've deleted all of the initial instances, and added two new contacts, your changes disappear and the dictionary contains only the initial three contacts. I couldn't find out, why or when this is happening. BUT: if I start the zope server in debug mode, everything is working fine ! I started the development with zope 2.4.0, but even the update to 2.4.3 doesn't solved the problem. I've read all the changes made since 2.4.0 to 2.5.0, but I couldn't find an entry matching my problem. I then thought to pickle the objects myself and save them to the linux filesystem. But it's not possible to pickle my objects, cause there are references to the zope ZODB and the REQUEST object, which is obviously not pickable. Do you know how to solve this problem ? I don't know, what to do else. In general, the whole application is based on the mechanism, storing objects and subobjects into the ZODB, cause HTTP is a connection-less protocol. Thanks for your help in forward. Yours Marcus Ollas. ___________________________________________ __ | | | \ / LOXCOM | | | \/ digital services GmbH | | | /\ Weseler Str. 67-69 |__ |__| / \ D-45721 Haltern Marcus Ollas Systems Engineering Telefon: +49 (0) 2364 / 9238-94 Telefax: +49 (0) 2364 / 9238-90 Mobil: +49 (0) 173 / 539 6150 Email: mco(a)loxcom.net ___________________________________________

Re: urlopen works outside Zope, not inside

I am reasonably confident that this is true. The following code runs successfully inside SciTE. def getCount ( ): from urllib import urlopen, quote from string import find searchFor = 'Cobol' arg = r'http://jobsearch.monster.ca/jobsearch.asp?brd=1&cy=CA&lid=236&fn=6&fn=546&f…' % ( quote ( searchFor), ) result = arg try: page = urlopen ( arg ) result += '<br/>%s: ' % searchFor for line in page.readlines(): loc = find ( line, "Jobs 1 to " ) if loc != -1: loc2 = find ( line, " of " ) loc3 = find ( line, "</B>", loc2 ) result += line [ loc2 + 4 : loc3 ] return result result += 'None found' except Exception, msg: result += '<br/>' + str ( msg ) return result if __name__ == "__main__": print getCount ( ) If I upload this into an External Method with function name "getCount" and then click on the 'Test' tab I get the following: http://jobsearch.monster.ca/jobsearch.asp?brd=1&cy=CA&lid=236&fn=6&fn=546&f…<br/>[Errno socket error] (10061, 'Connection refused') Would appreciate any more thoughts you might have.

ZClasses and non-ZMI interface (was: how to add a ZClass instance from Python)
by Luca Manini 31 Mar '02

31 Mar '02

I'm trying to get a basic undestanding of the various techniques available in Zope to create a very common kind of application: something where you have one (or more) classe that implement your "business domain data and logic" and you want a GUI to create/edit/list/delete instances of those classes. For any part of the job there are many different ways to do the needed thing and I would like to explore at least some of them in a as-simple-as-possible example. For each approach I would like not only to find "a" solution, but I want to find out how to write it in a way that allows it to be changed with another one without hurting too much the rest of the app. For example to go from plain ZClasses in Folder to Python Products with Specialist without rewriting the interface (presentation) stuff. I think Zope has the needed "flexibility" but, still, one has to find out how to take advantage of it. When I say "application's parts" and "different ways to do things" I mean: For the back-end: 1) pure ZClasses (everything done via ZMI), 2) ZClasses based on external Python classes, 3) pure Python ZClasses. For the storage: 1) instances added to "plain" Folders and "saved" in ZODB, 2) database backend (with hand-made SQL methods), 3) ZPatterns (with Specialists, Data-Skins and Racks). For the interface: 1) the ZMI and the automagically (for ZClasses) created stuff, 2) something you roll yourself. And finally (at least for the HTML/Web newbie, like me) you have to survive the various "technical" ways to set up the interface: 1) to frame or not to frame, 2) to javascript or not, 3) use links (<a heref...>) or buttons, 4) how to substitute for the missing "modal" windows (that is how to jump to another page and come back home). The ZopeBook examples, other "known" examples like Poll, ZPatterns examples (Attendance and Lunch) do show different ways to do different things (also with different "style" depending on the writer) but they do not (seems to me) explain the "why" and the "how else". I would like to make one thing in many ways, understanding (and commenting) the pros and cons. I will surely ask for help on the list, so I hope I'll be able to give back some "zexp" or some "how-to". If you are still reading, here comes some initial stuff! See attaches for: - zexp's of the Product (import in Control_Panel/Products), - zexp of the example (import wherever you want), - kind of how-to for both (for your eyes only). I'll wait for feed-back (i.e. interest) before sending more stuff to the list (sorry no personal web-site yet for that). bye, Luca.
