Starting Zope -error msgs

Just finished an install of the Zope-2.0.0-src for Slackware Linux - kernel 2.2.6 No error mesages during ./configure, make, or make clean. suid to root and make install -no errors got the master login & password but when I run the start script or python z2.py I get the following errors: Traceback (innermost last): File "z2.py", line 366, in ? import ZServer File "/tmp/Zope-2.0.0-src/ZServer/__init__.py", line 123, in ? from HTTPServer import zhttp_server, zhttp_handler File "/tmp/Zope-2.0.0-src/ZServer/HTTPServer.py", line 116, in ? from HTTPResponse import make_response File "/tmp/Zope-2.0.0-src/ZServer/HTTPResponse.py", line 99, in ? from medusa import http_server, asyncore File "/tmp/Zope-2.0.0-src/ZServer/medusa/http_server.py", line 720, in ? tz_for_log = compute_timezone_for_log() File "/tmp/Zope-2.0.0-src/ZServer/medusa/http_server.py", line 703, in compute _timezone_for_log if time.daylight: AttributeError: daylight Mike Kompar Manager of Client Services IBS a division of Modern Technologies mikek(a)mtcibs.com http://www.mtcibs.com

Developing External Methods
by victor＠idaccr.org 08 Sep '99

08 Sep '99

I've just installed Zope, and as an initial test I entered the various files from the "Job Board" example given in a "Technical Introduction to Object Publishing with Zope". However, when I try to "Add External Method", I get the error "Error Type: AttributeError Error Value: func_defaults" with no line number given. I really can't see what the error is. I haven't really tried staring at the locations of the traceback in the Zope functions, but should this really be necessary?! So this brings up the general question: when you're writing new External Methods, what development methodology do you use? Unless you're perfect (and I'm not one of these) and never make any errors, you certainly need something which will get the methods, debugged, etc. Also, I also tried, the alternative suggested in the "Zope Content Managers Guide" of putting the external methods in the Extensions subdirectory of a Product (I made a new product called "Test"), but even though I gave Test.JobBoard as the name of the module file, it couldn't be found.

Inconsistent aquisition behavior between Zope versions
by Paulo Eduardo Neves 08 Sep '99

08 Sep '99

Hi, I had to spent some time out of this list and now I'm trying to upgrade to Zope2 and to catch on with all the news. Everything seems to work fine with my upgrade, but I'm with a problem with a site pattern I use a lot. I'll first describe the site design pattern I use with an example. I have a SQL method to get a list of cities, if an state_id variable is defined I just get the cities of that state. Here is the "getCities" SQL method: SELECT * FROM city  WHERE state_id=  It doens't have any arguments. I have a subfolder "state18" that is almost empty, it just defines an int property: state_id=18 When I test the sql method everything works fine. In the base folder the query returns all cities, if I add "state18" to the query url, the query just returns the cities of state number 18. The problem happens when I use the query inside a DTML document. If I have a DTML method "showCities" that list just list the cities and is inserted inside a document "cities". I get: In Zope 1.10.3: http://mysite.com/basefolder/cities => returns all cities http://mysite.com/basefolder/state18/cities => returns cities of state 18 In Zope 2 http://mysite.com/basefolder/cities => returns all cities http://mysite.com/basefolder/state18/cities => STILL returns all cities If I change the cities document to a method everything work as expected. If anyone want to test it, I can send simple example folders for Zope 1.10 and Zope 2. Any help? -- Paulo Eduardo Neves maito:neves@email.com Rio de Janeiro - Brasil

ZClasses Aquisition
by Ben Leslie 08 Sep '99

08 Sep '99

Hi everyone, I am currently getting my teeth into creating ZClasses, which seem to be very powerful. I have one question which I hope someone can help me with. I am creating contact pages for different division with our company. Each division has a bunch of properties (phone, fax, email etc) and also has a number of staff which are stored as sub objects. So I have: division staff1 staff2 staff3 Each of the staff also have phone, fax, email etc. What I would like to do is if a phone, fax or email has not been specified for a certain staff member then it should be inherited from the division. Hopefully that makes sense. Thanks in advance for any help. Cheers, Benno

(The real question here >is "How do people backup their remotely-hosted Zope websites?") I backup my website just by FTPing the "Data.fs" file. This is the entire Zope DB, in one convenient place.

Clearly, this forum favors >Zope. Are there situations in which PHP is a better choice? Has anyone yet >written a detailed comparison of the two products? I used PHP quite a bit in '96 and '97. I know it has changed quite a bit since then, but most of the changes have been object extensions to the language, new modules and performance (as far as I've seen). To me, PHP is something that can be more readily compared to Python. PHP is really a scripting language, it just happens that it is a scripting language geared toward the web and is designed to be mingled with your HTML. Zope's web object model, object database, ZClasses, ZCatalog, permissions system, etc. really make it feel like it is a layer above PHP in terms of the services it provides. It makes it easy to do many things that web folks commonly want to do, and makes it easy to extend if you want something that is not quite so common. I recently took another look at PHP (when I read about PHP 4.0 beta). I think I'm inclined to agree with Michel... once you reach a certain point of knowledge with Zope, you're not going to want to turn back. Kevin

This will pass the *string* '['item 1', 'this is item 2', 'I am the third item in the list']' as *one item in a list*. You cannot pass along python objects through HTML <input> elements, they are just too simple. All they can provide is a mapping between a name and a string value. To do so, you would need to _build_ your hidden input fields: <form action...> <dtml-in desc> <input type="hidden" name="desc:list" value="<dtml-var sequence-item>"> </dtml-in> </form> This will put an <input...> in your HTML for every element in the list 'original_list'. When the 'action' of this form gets called, ZPublisher will marshal all of the <input...>s into a list called 'desc'. And then your code will work. -Michel

(The > real question here > is "How do people backup their remotely-hosted Zope websites?") The Zope database can be imported/exported in it's native format or XML. There are gobs of ways to put content into Zope via any one of a number of means to detailed to go into here. The answer is 'Yes'. > 2. Is it easy to have multiple Zope databases? Yes. Why? > 3. Is there an easy way to do a global search-and-replace > over an entire > Zope-based web site? The Zope database contains much more infrastructure than either a flat file or a relational database. The concept of 'search and replace' has no easy definition in such an object system. Of course, you can 'export' the database to XML, munge it, and re-import it, but it would be far saner to understand your problem and programaticly 'search' and 'replace' what you care about, as apposed to some global specification. As an example, lets say you had two objects who both had properties 'author'. And you wanted to globably search and replace 'author' with 'creator'. Ok, no big deal. Now, lets say you also had an object *named* author. Should it be replaced too? It has no semantic relationship to the other two objects who have *properties* named 'author'. The three objects may be completely unrelated. > 4. Is there a way to write DTML macros?

Yes, just create a DTML method called 'dtml_table' containing: <table cellpadding="0" cellspacing="0" border="0" width="100%"> and call it in another DTML Method or Document: <dtml-var dtml_table> > Additionally, how easy is it to code new DTML tags? I'm relatively > well-versed in Python. Very easy. As a trivial example, see the Zippy tag: http://www.zope.org:18200/Members/michel/Products/Zippy and MIMETools.MIMETag, which comes standard with Zope in lib/python/Product/MIMETools/MIMETag.py. I use these two as an example because I wrote them. Most of the 'standard' tags can be found in lib/python/DocumentTemplate/*.py > Also, if anyone has used both Zope and PHP, I'd be very > interested to see a > (more or less) objective comparison of the two. Clearly, > this forum favors > Zope. Are there situations in which PHP is a better choice? > Has anyone yet > written a detailed comparison of the two products? PHP is just code in your layout. Zope has: standard persistence system, abstractions of data into standard objects, standard security model, standard database-transparent Object Relational Integration, web managment interface, FTP, WebDAV, IMAP and XML-RPC native protocol integration and much more. I don't know what PHP has, because I've never used it. Your right, I'm biased. But how about I make a biased prediction? If your versed in Python, after using Zope to the point of 'enlightenment' you use Zope for every project thereafter and not PHP (unless someone pays you, of course ;). -Michel

Re: Image.py modifications.
by Steve Jibson 07 Sep '99

07 Sep '99

We were planning to do the exact same thing for our site, so I think it's a great idea. There may be even more to the solution. The Zope folks should probably look at the html standard for the image tag and add all attributes that are defined there to the image class. (I haven't checked the standard, maybe height, width and border are the only ones.) > Date: Tue, 07 Sep 1999 13:11:12 -0300 > From: Mauricio Souza <mauricio(a)hiper.com.br> > Organization: =?iso-8859-1?Q?Hiperl=F3gica?= > To: Zope(a)zope.org > Subject: [Zope] Image.py modifications. > > In my Zope 1 and Zope 2, i do a modification on the Image classes.
