Zope 3 and Rails - a pragmatic and agile comparation (put the hype aside)
by Marcelo de Moraes Serpa 26 Feb '08

26 Feb '08

Hello, I come from a Rails background, been working with Rails for about 1 year and a half, it has been a great experience but my last project required me to use Plone as a base framework for the portal/application. I then started deeply studying Plone 3. Bought and read Martin's excellent book Professional Plone Development from cover to cover. Struggled with Zope concepts but almost always could grasp them by reading the other books from the Zope/Plone bookshelf or online articles/tutorials. It has been 3 months already. The project is almost done and I've learned to like Plone and Zope 2. However, what attracted me the most was Zope 3 and its elegant concepts and OOP patterns and this led me to question some things: * The differences in the approaches taken by Rails and Zope 3 to provide developer productivity, scalability and application maintability. Rails is productive, no doubt regarding this. However, I feel that it restricts me in the OOP side of things, hiding much of the OOP patterns from the developer. The "put there it will just work" philosophy often makes it hard (at least harder than if it were being implemented on Zope 3) to make more advanced, complex and specific things. I do believe in the agile methodology and I always follow it whatever I am working with Java, python, C or Rails. Rails just happens to be an out-of-the-box solution that has attract millions of developers becouse of its magic promises and easy learning-curve. I feel however, that Zope 3 with its Component Architecture is much more elegant and can be as productive as Rails AND provide better application scalability and maintability than Rails if you know what you are doing. I can't speak for Zope 2 though :) What do you think? Would you mind sharing your experiences and ideas regarding this subject? Cheers, Marcelo.

Re: 2.10 and ZClasses

I understand and appreciate your responses. Finally got some things straightened out and after changing DA settings to point to real database servers (instead of localhost), and commenting things out that were calling unneeded parts, I am able to get our site up (on some pages) with yesterdays news stored in the Data.fs. I am able to view an actual news ZClass objects with our site header and footer wrapped around it. Not bad. That shows they do work. Long way to go but it's a start But, on the page that does the catalog lookup of the day's news stories, it is a blank page. No errors in the error_log. But if I go to the ArchiveCatalog (our name for our Catalog) and click on the Catalog tab in the ZMI, I get this error: Traceback (innermost last): Module ZPublisher.Publish, line 119, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 42, in call_object Module Shared.DC.Scripts.Bindings, line 313, in __call__ Module Shared.DC.Scripts.Bindings, line 350, in _bindAndExec Module App.special_dtml, line 178, in _exec Module DocumentTemplate.DT_Let, line 76, in render Module DocumentTemplate.DT_In, line 584, in renderwb Module Products.ZCatalog.Lazy, line 144, in __getitem__ IndexError: list index out of range All the other tabs work.

2.10 and ZClasses
by Allen Schmidt Sr. 26 Feb '08

26 Feb '08

We are still running 2.7.5 but really want to upgrade. Changes.txt in 2.10.5 state ZClasses are deprecated. CAN they still be used?? Not at all or just not recommended and why? What is the highest version we can safely upgrade to then? Thanks Allen

zcatalog, brains & keywordIndex
by Stefano Guglia 26 Feb '08

26 Feb '08

Hello everybody.. I have to index some data from a mysql query recordset and all works OK but..I added a keywordIndex to store (with the same url) multiple values related to the above recordset. It seems I cannot use brains (query results are strings). Probably a newbie question, but I really do not know how to update a keywordIndex starting from a list..Any help (+sample code pls :-)) ? Thanks, Stefano.

Need Server
by Victor Subervi 26 Feb '08

26 Feb '08

Hi: I am out of business and I need someone to host a client's site (for which they will obviously pay). Requires Zope 2.78 and ZMySQL. Have everything you need. I would need to get into the ZMI to set things up, but don't need server access. Please write me off-list. TIA, Victor

Zope Calendar Product?
by Cliff Ford 25 Feb '08

25 Feb '08

Hello friends, I have been away from Zope for a while. I have a Zope 2.9.3 installation (no CMS or Plone) for which someone has requested a Calendar application. From the Zope sites it is not clear whether any suitable product is available. Could anyone recommend something? Alternatively, might it be an idea to use a stand-alone Calendar application and plug it into an I-frame? Cliff

If I understand well, brains are there just for this purpose. I'm just a beginner in zope, so please let me know if there are more effective ways to do that.

Frequent Zope crashes (Zope 2.9.8)
by Paul Brettschneider 23 Feb '08

23 Feb '08

Hello, my Zope 2.9.8 instance crashes up to 6 times per hour. This is very unfortunate since the constant restarting brings performance to its knees. It runs under Linux in 64 bit mode on an AMD64 . I managed to catch two backtraces with gdb (see end of the mail). Both backtraces show a crash in cc_oid_unreferenced(ccobject *self, PyObject *oid) in persistent/cPickleCache.c: Either in line 576: v = PyDict_GetItem(self->data, oid); or in line 607: Py_DECREF((ccobject *)((cPersistentObject *)v)->cache); v and v->cache seem to point to heap: (gdb) print v $1 = (PyObject *) 0x5f8920 (gdb) print ((cPersistentObject *)v)->cache $2 = (PerCache *) 0x613620 Always called from Per_dealloc(cPersistentObject *self) in persistent/cPersistence.c in line 578: cPersistenceCAPI->percachedel(self->cache, self->oid); Is this a known issue?
