What would you program these >with? Well, for Apache there's PHP or mod_perl, which do offer sessions, authentication(via externally-written modules), database API, and quite fast too. Of course they do not have most of the 'unique' object-oriented features of Zope (as listed on Zope website), and don't have the "manage-everything-thru-the-browser" feature (but projects like midgard may be catching up?) >Of course Zope is slow. But apache doesn't have a tenth of the >functionality of Zope (on my system, ZServer is 1/20th of the >total Zope code) Well, i do appreciate the 'extra' features that Zope provides, but speed is still a matter of concern here. Imagine showing my boss "what my website can do" and all those advanced features, but it crawls like a snail... Anyway, thanks for your reply. I will certainly pick up 'Zope':), but just wondering whether it will replace what i have been using, i.e. PHP. regards, firestar ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Re: [Zope] the "manage_" methods

The method adds a DTML Method to its folder (it is a folder method) and gives it "id", "title". The content is taken from "file". The REQUEST probably is used only for a "redirect" after the operation. > But there is no details about how this works, what´s required. Is there any > documentation about them?

If you do not find anything, you can look at the source. Zope code is quite readable (mostly). Dieter

Re: [Zope] Error tracing...

Is there some way to write out variables or do > I just have to guess??? The traceback tells you, where the error was detected, as oneone else already pointed out. In your case, it seems that the problem was either detected by ZPublisher or by Z SQL Method. They have encountered a parameter/form name with an ":int" suffix. This tells them to convert the value into an integer. However, in your case, the value was empty. Your error, "Empty (form) entry, when integer expected". Dieter

The PoPy-1.2.tar.gz file doesn't seem to be available from the ftp.mixadlive.com site. Would anyone out there mind emailing me the file? Thanks, Eric.

Nested dtml-in loops (was: [Zope-dev] SQL-Output)

Andre Schubert writes: > ... problem with names clashes from nested dtml-in loop ... Your problem may be generalized: <-- l1 and l2 are sequences --> <dtml-in l1> <dtml-in l2> <-- here you need to access both components from both the inner and the outer dtml-in There may be a name clash between the two (implicite) loop variables --> </dtml-in l2> </dtml-in l1> You can use renaming to avoid any clashed. I demonstrate it for "sequence-item". <dtml-in l1> <dtml-let outer_lv=sequence-item <-- ATTENTION: calls it! --> > <dtml-in l2> ... <dtml-var outer_lv> <-- the outer loop value --> <dtml-var sequence-item> <-- the inner loop value --> ... </dtml-in l2> </dtml-let> </dtml-in l1> If you want to prevent the outer loop value to be called, you may use "_.getitem('sequence-item')" rathen than just sequence-item.

Invalid column name 'UuZ'. Invalid column name > 'UuZ'. > > That mean that the operator ">" can only compare two number. It means that "UuZ" is interpreted as a *column name*, i.e. as a field in your database and not as a string. This is because, it is not enclosed in '...'. Such a column does not exist; therefore, the invalid column name errors. Instead of "<dtml-var alphabet>" you should use "<dtml-sqlvar alphabet type=string>". It does represent the constant string value correctly. Dieter

Re: [Zope] Calling Stored Procedures using DCOracle

Notice the (potentially) essential difference: In "callproc" you use "addarticle" (i.e. all lowercase), but in "getSource" you use "ADDARTICLE" (i.e. all uppercase). Maybe, case is essential. > In short I need to run my stored procedures from python. They are all ready > and waiting to be used. Some one help me :-) Some days ago, I extended ZOracleDA with a method to call a stored procedure. ZOracleDA gives me a cursor. I used: return cursor.procedures.<my_procedure_name>(<my_arguments>) worked fine. Dieter

Re: [Zope] Sql result searchs with Z Catalog

I cannot imagine why someone wants to emulate a fast relational search by a (comparatively) slow ZCatalog search. Thus, I must miss something. Anyway. ZCatalog is happy to catalog anything that is URL addressable. Using direct traversal (--> Z SQL User Guide) you can make database records URL addressable. You probably will need an explicit loop over your query result set and call "catalogObject" for each of them. Dieter
