HowTo Render txt-Files with LocalFS in PythonScript?
by Elena Schulz 06 Aug '02

06 Aug '02

Dear List, with the following PythonScript I try to render the content of txt-Files with LocalFS according to the howto of LocalFS (...snip..." To insert the text of the file after evaluating it as a DTML template in the current namespace, you would use: <dtml-var "test['foo.dtml'](_.None, _)"> .....snip ..."). My Script: ## Script (Python) "getContentFiles" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters=REQUEST=None,myLFSInstance ##title= myLFS = getattr(context, myLFSInstance) print myLFS['textfile.txt'](_.None,_) but I get the below Error-Message. If I try: print myLFS['textfile.txt'].data the content is returned but without rendering (as expected). Does anybody know how to get the rendering done? Thanks a lot for your help, Elena Error-Message: Error Type: AttributeError Error Value: __call__: Traceback (innermost last): File J:\Zope\ZopeSite\lib\python\ZPublisher\Publish.py, line 223, in publish_module File J:\Zope\ZopeSite\lib\python\ZPublisher\Publish.py, line 187, in publish File J:\Zope\ZopeSite\lib\python\Zope\__init__.py, line 226, in zpublisher_exception_hook (Object: jobs) File J:\Zope\ZopeSite\lib\python\ZPublisher\Publish.py, line 171, in publish File J:\Zope\ZopeSite\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: index.html) File J:\Zope\ZopeSite\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: index.html) File J:\Zope\ZopeSite\lib\python\OFS\DTMLMethod.py, line 199, in __call__ (Object: index.html) File J:\Zope\ZopeSite\lib\python\DocumentTemplate\DT_String.py, line 546, in __call__ (Object: index.html) File J:\Zope\ZopeSite\lib\python\OFS\DTMLMethod.py, line 192, in __call__ (Object: inhalt) File J:\Zope\ZopeSite\lib\python\DocumentTemplate\DT_String.py, line 546, in __call__ (Object: inhalt) File J:\Zope\ZopeSite\lib\python\DocumentTemplate\DT_Util.py, line 231, in eval (Object: getContentFiles(_.None,sourceFolder,contentFiles)) (Info: getContentFiles) File <string>, line 2, in f (Object: guarded_getattr) File J:\Zope\ZopeSite\lib\python\Shared\DC\Scripts\Bindings.py, line 324, in __call__ (Object: getContentFiles) File J:\Zope\ZopeSite\lib\python\Shared\DC\Scripts\Bindings.py, line 354, in _bindAndExec (Object: getContentFiles) File J:\Zope\ZopeSite\lib\python\Products\PythonScripts\PythonScript.py, line 363, in _exec (Object: getContentFiles) (Info: ({'script': <PythonScript instance at 01F468C0>, 'context': <Folder instance at 01F4D430>, 'container': <Folder instance at 01EF0530>, '_': <TemplateDict object at 01EB1A30>, 'traverse_subpath': []}, (None, 'stxTexte', ['jobs.txt']), {}, (None, None))) File Script (Python), line 16, in getContentFiles AttributeError: (see above)

Zope Examples - Shopping Cart
by Rares Vernica 06 Aug '02

06 Aug '02

Hi, I'm trying to figure out how a shopping cart is working in Zope. I've looked at the "Shopping Cart" Example in Zope (2.5.1). The "index_html" is in ZPT language and I rewrite it as a DTML Method/Document. The page seems to work until I push the "Add Items" button, on the next page I get the error message: Error Type: KeyError Error Value: standard_html_header Here is the contents of my "index_htm" page (only the "Add item" part): <dtml-var standard_html_header> <h2>Add Items</h2> <form action="addItems"> <table cellpadding="8" cellspacing="0" border="0"> <tr align="left" class="normal"> <th>Item</th> <th>Description</th> <th>Price</th> <th>Quantity</th> </tr> <dtml-in getItem> <tr valign="top"> <td><dtml-var "_.getitem('sequence-item')['title']"></td> <td><dtml-var "_.getitem('sequence-item')['description']"></td> <td><dtml-var "_.getitem('sequence-item')['price']"></td> <td> <input type="hidden" name="orders.id:records" value="_.getitem('sequence-item')['id']"> <input type="text" name="orders.quantity:records" value="0" size="3"></td> </tr> </dtml-in> <tr> <td colspan="2"></td> <td colspan="2"><input type="submit" value="Add Items"></td> </tr> </table> </form> <dtml-var standard_html_footer> I've left the rest of the scripts unmodified. What could it be? Thanks in advance, Rares _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

Re: [Zope] Zope in intranet - the cool apps?
by Kevin Erickson 06 Aug '02

06 Aug '02

Here's my $.02 on potentially the coolest Zope app for intranets. To me, that would be a portal that takes CMF / Plone to the next level. Features would include.. - functionality similar to MyYahoo and other portals that allow a user to customize content that they see - content would be developed into "gadgets" or "portlets" to use other portal companies' terminology. - gadgets would be made available to users based on what group or "community" they belong to... e.g. Managers, Executives, Customer Service Rep. - communities would integrate with a corporate directory, e.g. LDAP - portal administrators could force certain content to users - management wizards would allow easy gadget development, e.g. use something like Kebasdata to pull html content from other sites, use a SQL tool to develop database content gadgets I've only been using Zope for a few weeks, but it seems to me that Zope is well-suited to this concept. It is certainly easy enough to create objects that can be included as content within some framework. Many of the things that would make good gadgets for a corporate portal are available as separate products... e-mail clients, SQL queries, etc. Bring them all together and you've got the killer intranet (or extranet, or internet) app. Kevin

Forms + MySQL + DateTime = a mess
by Dennis Allison 06 Aug '02

06 Aug '02

Someone else musta been tossed into this quagmire. I have a set of forms which gather information including dates. They are intiialized either by values from the MySQL database, today's date, or values captured already; the dates are written to the database. The database values are of type datetime. The current code keeps having problems since for some sources the date is a string (possibly syntatically invalid) and from other sources, it's a datetime object. It also appears that the MySQL database adaptor converts incoming datetime data into DateTime objects. Anyone have suggestions as to how to manage dates in this context. I'm about to rip out everything that uses DateTime objects, replace it with strings, and relegate DateTime to a very limited context.

ZDataQueryKit KeyError w/ Interbase/Firebird
by Derek Basch 05 Aug '02

05 Aug '02

Hello, I am trying to learn how to use ZDataQueryKit w/ Firebird/Interbase and I keep getting a KeyError. I create a simple ZSQLMethod such as "SELECT * FROM T_CONTACTS" and name it "testmethod". I then create a Z Report Tool with the id and title of "report" and a Data Source of "testmethod". I press Add and Edit and I get: Zope has encountered an error while publishing this resource. Error Type: KeyError Error Value: PK_CON_ID I thought it might have something to do with the primary key column but I tried just selecting a non key column and it still fails. Rather than mucking around in code for hours, I thought I would ask if anyone has an idea what im doing wrong? Thanks in adavance, Derek T Basch __________________________________________________ Do You Yahoo!? Yahoo! Health - Feel better, live better http://health.yahoo.com

Impossibly long urls
by David Beech 05 Aug '02

05 Aug '02

Hello folks, Can anyone explain why my Zope apps generate loooooooooooong urls? It seems that each action (clicking a button or an href) results in the target (the object being called) being appended to the current url which is submitted to the server. I've pored over the various Zope references but nothing sticks out as obvious. I've tried specifying the path directly to a Zope object in both Python scripts and dtml documents, and also used relative linking where possible. The effect is always the same and apart from causing the server to overwork it also leads to problems with database operations. Any help will be much appreciated. cheers David

Re: [Zope] why two session identifiers?

On the other hand, if "browser id" and >"token" are conceptually to be kept distinguished, why do they have the >same >value? And, again, what's the 'token' field intended for? The "token" is the browser id. The "id" is the session id. The __repr__ of a session data object prints out the browser id as "token" for "hysterical raisins". Printing the value of "token" is not redundant, it's just misnamed. It should really label it "browser id". This could be considered a bug if you're super-picky. ;-) >??? If this is so (i.e. if the session id is not stored or seen on the >client in any way), what about the >id: 10285673650225743670 >key-value pair contained in the cookie sent to the client browser? >Please, explain further on. There is no such key value pair in the actual cookie sent to the browser, you're mistaken. The cookie only contains the browser id. You can check this if you like by examining a browser id cookie on your filesystem. HTH, - C

preventing add list pollution - how?
by Oliver Bleutgen 05 Aug '02

05 Aug '02

I knew the best practice to do that, but I forgot it, and don't find the solution on zope or elsewhere, and probably I'm confused. Say I have a container product, and objects which just will be added to that container or its subobjects. Therefore I don't want the subobjects to appear in the general add list, just in the add list of the container. I know how to manipulate that add-lists, my problem is what to do with the subobjects to get them into zope "properly". Do I write my subobjects like normal zope product, just without registering them with zope as products? Do I then add instance of my subobjects to a container just using _.setObject? cheers, oliver
