So, I guess your issue is that your page templates are combining data from other zope objects which are in different encoding. I doubt that you can convert all your objects to the same encoding as a general rule because that will be dependent on the specific object implementation. Even if you convert the data part of the objects, the code might still not work properly. But I don't know which type of objects you are talking about. Maybe one approach would be to export your data.fs as a whole or in parts using XML format and then try to make sure its encoding is utf-8.

But now I'm more confused than ever. Sareesh, could you be more specific about what confuses you? You have several routes, you need to give proper consideration to those routes. Maybe it would also help us if you clarify what is your skillset and experience in software development. Also, is your problem a CIM one? see http://en.wikipedia.org/wiki/Computer-integrated_manufacturing and specifically the key challenge listed over there. I have the impression you might be underestimating the problem. Finally, do you already have information about the tools in some electronic format? And what about the rules to choose tools? Is there already some computer based solution to help with the current problem? Please keep in mind that OOP and Object DB is not the same thing. You can work with objects in Python and never rely on OODB. I have serious doubts about using ZODB at your stage because AFAIK, creating custom objects requires the development of zope Products. Note that the zope book does not teach you about creating custom objects in the ZODB. You need another whole book for that. And the combination RDB and ZODB suggested by Neils/John seems too complicated as a start. I think you have a high learning curve ahead of you if have to learn to create Zope Packages to put objects in ZODB. But maybe there are simpler ways that I am not aware of. I'm sure OOP in Python and RDB is a good option. ZODB itself, I'm not so sure. Maybe others can enlighten you better here. It appears to me you don't have much experience and it looks like there is a long evolutionary project ahead of you. For these reasons, I would highly recommend Python. BTW, I never recommended and I do not recommend C/C++ for your needs, I just mentioned that I used it for a similar purpose many years ago. I would recommend you to do some programming in Python just to read some tool data from a text file, create some objects and try to do some tool selection where the output is merely done with print. Then you can upgrade to use MySQL to store your tool data and then you can decide if you go the Zope or the PHP route. Keep in mind that RDBs are a huge standard with many people and tools around it, whereas ZODB is very much a small niche in comparison. That should also weigh in your criteria.

Re: [Zope] Help in deciding approach to Web App
On 12/04/2011 09:52 AM, Sareesh Sudhakaran wrote: Thanks Niels. Just to clarify: Does my particular instance fall under an OODBMS model or a RDBMS model (with ORM if necessary)? Data modelling is a bit of an art and probably you could tackle your problem with any approach. I think the important is for you to figure out which model suits more your personality. No kidding. I would personally start with the RDBMS approach considering only the information you provide. Also, you can easily use zope in combination with a RDBMS. When you read the book, beware that zope has been changing from a through the web approach, to a typical file system based approach, which is a loss, but it seems to be what suits the needs of the zope developers. The approach I use is: zpt page - (one) Python Script - (some) ZSQL Methods - MySQL The zpt defines the layout of the pages, the ZSQL Methods retrieve the data needed and the Python script massages the data to make it suitable for the ZPT page. Or the other way around, from user input in a form to storage in the database. The advantage of the relational approach is that it is a very well understood model and although different people will still come to different models there are sufficient objective guidelines out there (e.g., the normalization rules, and then criteria for when to denormalise) to help you along. Furthermore, there are lots of people in db-related forums that can help you. Also, RDBMS provides you with a standard query language, SQL, which plenty of systems and tools can use. In general, RDBMS gives you the safest approach to keep your data and not loose it when you need to migrate either the front-end or the back-end. This language is very powerful and can avoid you a lot of low level programming. However, plenty of people can not deal well with SQL because it follows a paradigm so different from the classic imperative programming. With SQL, you specify the what, with the other languages you specify the how. The advantage of the what is that you can do a lot of data processing in a few lines of code. The problem with the what is that because you don't know the how of it, you feel you don't have control and you are led to say the language is obscure or unreadable. However, even if you are not comfortable with the what (you have to try to know), you can still rely on an library like SQLAlchemy to keep you a bit in the comfort zone of the how. So instead of learning SQL, you need to learn the API of a specific library. Your choice. I recommend the first by far. The real main issue with Relational is that it is a highly structured data model. It allows you to keep high quality data but if you don't get it right soon enough in the development cycle, some later changes can have a huge impact in the application, requiring rewrites. Furthermore, it works the best when you have many objects with the same properties. If you have many entities all different from each other (the tools in your case, maybe), then maybe a OODBMS might be better. But here, there is no standard language, or standard whatever. Perosnally, I would avoid as much as possible to put data in something like ZODB (I use it merely to store and manage the application). The problem with your specific case is that it does not seem to be a typical case of books and authors, which might be a risk for someone without experience. The issue Tool A might have only three fixed rpms - 100, 200 and 500, but Tool B might have rpms from 20 to 2000, is indeed tricky. I suspect in general the needs of your system will be too specific to be able to rely only on SQL queries. You would need to put a lot of intelligence in the data (really highly structured) and it might become unmanageable or not scalable. I guess you will need to put a lot of intelligence in the Python Script. So, the ZSQL retrieves the relevant tool data and then makes the tool choice. The knowledge of the meaning of the attributes is maintained in programming. I should say I am not totally sure the Python Script is the best approach here, in terms of management facilities. But Python is surely a very good language due to its readability. However, you might need to use External methods or a more typical file-system based Python approach. Or maybe you actually need to create a Domain Specific Language to encode the intelligence needed for your tool selection process. If your python code becomes repetitive, with patterns showing up, then a DSL might be a good approach, but this might be too much engineering for you at this stage. It looks like you are in a typical CIM scenario and I remember handling a similar problem 20 years ago. I vaguely remember at that time to use custom graph structures in C and the the intelligence was coded in Lisp/Scheme. So, there is a big range of solutions to try out :) If you have time, then the simple approach zpt page - (one) Python

(no NTLM and it uses kerberos but on it's own) Thanks, Fernando ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
RE: [Zope] LocalFS problem
Hi Chris, Fernando Martins wrote: I'm using LocalFS 1.7rc? and Zope 2.8.? in a Suse system. More importantly for this case, zope is behind Apache 1.39 with module NTLM, What are you using to do NTLM? simply mod_ntlm. I'm following the procedure on this page to do single sign-on for my Intranet web site: http://diaryproducts.net/about/cms/zope_plone/zope_plone_sso_single_sign_on_ windows_domain The software used is also linked from there. through FastCGI, Why on earth would you inflict this on yourself? ;-) Because it is the only way to pass the Apache environmental variable REMOTE_USER to Zope. This variable is set by Apache after the NTLM authentication. I suppose PCGI is also possible, but I haven't tried it out. I'm well aware and concerned that FastCGI has become deprecated for lack of maintainer. I guess this will be a major upgrade obstacle for those doing Intranet single sign-on. Other than that I don't know of any concrete FastCGI problem. When I access a file in a LocalFS folder I get the following info, instead of the pdf file (in this case): open file '/work/docs/MyFile.PDF', mode 'rb' at 0x42310974. What's the code and urls you're using to access this? No code, I get this in the browser just with an url like this: http://mysite.intranet/docs/MyFile.PDF /mysite/docs is a LocalFS folder that maps to a (Linux) folder /work/docs. (/mysite is a zope folder invisible for the users, through some URL rewriting done in Apache) The LocalFS folder accessed in the past through Apache+mod_rewrite without NTLM+RemoteUserFolder used to work fine. Interesting... yes, it was after adding NTLM+FastCGI to Apache+Zope that I got the LocalFS problems. So, the combination Apache+NTLM+FastCGI+RemoteUserFolder with LocalFS isn't working well. My guess would be RemoteUserFolder is the cuplrit. What is this RemoteUserFolder and where did you get it from? Got it from http://www.zope.org/Members/djay/RemoteUserFolder although I don't follow your logic since RemoteUF works fine with the rest of zope. RUF doesn't do any real authentication, I guess, it simply adds the REMOTE_USER user to the user folder and lets zope know the user is authenticated. Simple job I guess.

[Zope] LocalFS problem
Hi, I'm using LocalFS 1.7rc? and Zope 2.8.? in a Suse system. More importantly for this case, zope is behind Apache 1.39 with module NTLM, through FastCGI, and users folder is a RemoteUserFolder. mod_rewrite and Virtual Host Monster is being used do do some URL rewriting. When I access a file in a LocalFS folder I get the following info, instead of the pdf file (in this case): open file '/work/docs/MyFile.PDF', mode 'rb' at 0x42310974. The same file in another folder behind Apache+NTLM works fine. The LocalFS folder accessed in the past through Apache+mod_rewrite without NTLM+RemoteUserFolder used to work fine. The same file in LocalFS accessed through zope directly (another port; no apache) is delivered fine. So, the combination Apache+NTLM+FastCGI+RemoteUserFolder with LocalFS isn't working well. The only clue I have is that I get the file object description rather than the file itself. Any hints?

[Zope] init.d script and out of place instances
Thanks for all the replies! I got quite a good picture of the situation. Final solution was to symlink zopectl into init.d and run update-rc.d.

[Zope] init.d script and out of place instances
Hi, As far as I can see and tried, the zope2.8 script only deals with instances which are created in the default instance directory, /var/lib/zope2.8/instance/. I would prefer to keep a specific instance of zope in a different directory, together with other related directories, e.g. files from LocalFS. That is, I prefer to have all directories of the application, zope or not, under a common directory. Is there anything wrong with this approach?? I tried to symlink into the instance into /var/lib/zope2.8/instance but the start script fails. BTW, where are the messages logged? (I'm running Ubuntu) Is there any solution? Is this specific to the distribution?

Andreas, was your testing with a 2.8.4-based system? I remember reading about the work that Mark Hammond did to make things better for Zope on Windows, but it looks like this might have spelled the end for Zope working on Win98 ;-) I think we are using 2.8.1 (we are using our own Zope version which is always tied to the normale release schedule). I've tried all versions from 2.8.1 and I always get the same error. I don't have MSVC to try the tarball install. I wonder if there is some detection code which is wrongly assuming I'm running an NT kernel. Maybe it's something in my system which is misleading zope. Is it simple to do a debug/stepping over zope to see what's going on? I've only used Boa Constructor a bit (hmm, I suppose threads are only started by the end of initialization).

RE: [Zope] Re: zope 2.8.4 on windows 98
From: J Cameron Cooper Probably this is just in the start sequence. You cannot, of course, run Zope as a service in Win98, since it understands no such thing. Quite possibly you can use runzope or whatever to execute it in a console. I can't say exactly as the traceback has been edited out of this thread (and I've deleted the old messages). Indeed it's in the start sequence and I'm not trying to run it as a service. This is the traceback: Traceback (most recent call last): File C:\Program Files\Zope-2.8.4\lib\python\Zope2\Startup\run.py, line 56, i n ? run() File C:\Program Files\Zope-2.8.4\lib\python\Zope2\Startup\run.py, line 21, i n run starter.prepare() File C:\PROGRAM FILES\ZOPE-2.8.4\lib\python\Zope2\Startup\__init__.py, line 99, in prepare self.registerSignals() File C:\PROGRAM FILES\ZOPE-2.8.4\lib\python\Zope2\Startup\__init__.py, line 320, in registerSignals Signals.registerZopeSignals([self.cfg.eventlog, File C:\PROGRAM FILES\ZOPE-2.8.4\lib\python\Signals\Signals.py, line 116, in registerZopeSignals SignalHandler.registerHandler(SIGTERM, shutdownFastHandler) File C:\PROGRAM FILES\ZOPE-2.8.4\lib\python\Signals\WinSignalHandler.py, lin e 207, in registerHandler sa = createEventSecurityObject() File C:\PROGRAM FILES\ZOPE-2.8.4\lib\python\Signals\WinSignalHandler.py, lin e 84, in createEventSecurityObject sidEveryone.Initialize(ntsecuritycon.SECURITY_WORLD_SID_AUTHORITY,1) pywintypes.error: (120, 'InitializeSid', 'This function is only valid in Win32 m ode.') I wonder if this could a problem of the installer, but doesn't seem very likely as I assume it doesn't change the source code. I didn't have the time to try the tarball in win98SE. I have no idea how much work that could be.

Yes, I believe this is intentional. Windows 98 is a seven year old OS with insufficient infrastructure to reliably run server tasks anyway. At least get Windows 2000, which has a decent kernel. However that does not mean that Zope won't run on Windows 98. For a recent project where we ship and install Zope on all customers desktop machines I had to do a lot of testing especially on Windows 98. I've been using zope 2.7.4 on win 98 for some development/testing, not as a real server. But I'm confused by your statement: if zope 2.8.4 is calling an NT security function, not available in win98, then it does NOT run on win98?? DO you mean there is something wrong with my win98 setup or that zope 2.8.4 could be patched to overcome this issue?

[Zope-dev] Problem with request/HTTP_X_FORWARDED_FOR
Hello, Sorry for the cross-posting but I've posted before on the zope list without reply. The following looks like to be a bug on the lookup of the request attributes. If request doesn't have the attribute HTTP_X_FORWARDED_FOR, the following TALES expression should return REMOTE_ADDR. In fact, it returns the empty string. p tal:content=request/HTTP_X_FORWARDED_FOR | request/REMOTE_ADDR/p Naturally, the following works ok: p tal:content=python: request['HTTP_X_FORWARDED_FOR'] or request['REMOTE_ADDR']/p Shall I file it as a bug or am I missing something?
