AJAX / HTML Fragment
by SpiderX 21 Apr '08

21 Apr '08

I'm writing my website to use AJAX for form posting and displaying content, and instead of using AJAX to parse XML and then update the DOM, I'm using Zope to create an HTML fragment and AJAX just writes it to the correct location on the page. It works really great for what I'm doing, but the only problem is that I get an error message: "Error: no element found Source File: http://myzopesite:8080/mywebsite/zz/NewNote Line: 1" NewNote is the location of the Python script which just posts the content to a database (it actually execs a stored procedure)... If I set the zsql query to "select 1 as true" at the end, that makes the error go away. That leads me to believe something in the javascript is wrong, so here's the relevant part of the javascript: $.post('NewNote',{py_projectid: projectid,py_who: userName,py_note: note}, function() { // it saved. update display $('#theNotes').load('AJX_ListNotes?projectid='+ projectid); } It is using jQuery, but I had it setup before as just a plain javascript, but I still had the same problem. So, why would I get a "No element found" on a POST query? Here is the content of the python script. It's as basic as you can get: return container.addnote(projectid=py_projectid, who=py_who, note=py_note) That is the only thing which expect a return value. If I change that to this: container.addnote(projectid=py_projectid, who=py_who, note=py_note) return 1 I don't get any error messages, but the "update display" never happens. So, I'd like to have no error messages, and I'd also like not having to pollute my zsql queries with stupid things like "select 1 as true". Any ideas on how to accomplish that? -- Thanks, Derek Wilson

Guarded __getitem__ with non-ascii unicode key
by Peter Bengtsson 20 Apr '08

20 Apr '08

Today I had to write this supporting method in my product to prevent a rather strange Unauthorized error in my Page Template. My docstring should explain what I understand:: def unsafe_unicode_dict_getitem(self, dictionary, item): """ Return the value of this item in a dictionary object. Simply call the __getitem__ of this dictionary to pluck out an item. Why call this unsafe_...() ? If you try to do this in a guarded context (e.g. Script (Python) (or Page Template)) you'll get an Unauthorized error: d = {u'\xa3':1} d[u'\xa3'] # will raise an Unauthorized error # this works however d = {u'\xa3':1, u'asciiable':1} d[u'asciiable'] Why? I don't know. The place where it happens is the parental guardian function guarded_getitem() from ZopeGuards.py By instead calling the __getitem__ from here in unrestricted python we can bypass this. """ return dictionary[item] Is my app unsafe now? Why is it not possible to get to __getitem__ if the key is non-ascii? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com

How do I migrate CacheFu
by Manuel Vazquez Acosta 17 Apr '08

17 Apr '08

Hi all, I'm moving a Plone site from one server to another. At the same time I have upgraded Plone 2.5 to 2.5.5. I have managed to move all contents without major problems. Now I'm dealing with CacheFu. It refuses to enabled. I digged into the code and notice this: 265 if installed_version != __version__: 266 # CacheSetup hasn't migrated yet so let's disable it. 267 field = self.getField('enabled') 268 if field is None: 269 self._updateSchema() 270 elif field.get(self) == True: 271 field.set(self, False) 272 if getToolByName(self, config.PAGE_CACHE_MANAGER_ID, None) is not None: 273 -> enableCacheFu(self, False) 274 (Pdb) installed_version != __version__ True (Pdb) So it seems I have not properly migrated CacheFu. How do I do that? Best regards, Manuel.

simple use case for rotating images
by David Bear 16 Apr '08

16 Apr '08

We are finding that flash is used to generate simple slide shows. I'm thinking it would be 'better' to use an ajax like method and zope to serve up a set of standard images. Anyone know of examples? I completely new to ajax and have looked at a few ajax libraries. So far they all see overkill for what I want. -- David Bear College of Public Programs at ASU 602-464-0424
