Make folder's default view the contents of an item based on latest date
by Praful Kapadia 05 Jan '07

05 Jan '07

Hi I'm using Plone 2.5.1 on Mac OSX 10.4 and Win XP. I have the following folder structure: Daily News All Archive 2006 Jan Feb ... Jan, Feb, etc are smart folder that select items based on their effective date. This allows news items to be automatically classified. I'd like users to add items to folder All. When users click Daily News, I'd like the most recent item to be shown. I don't want a link to the most recent item but its contents so Daily News always shows the contents of the most recent news item. Someone suggested adding a smart folder (say, Latest) under Daily News and letting it pick items. Then make Latest the default content item for Daily News. This however results in the items being shown as a list of links in Daily News. I want the content of the latest always visible under Daily News. Any suggests? If I have to code something, please provide clues. I've developed in many languages but not Python (I'm going through Python in a Nutshell, at the moment). Thanks Praful

Limit size download file in Zope wih LocalFS
by Alan 04 Jan '07

04 Jan '07

Hi List! I got a problem. I found out that any file located in a LocalFS folder bigger than 128 Kb (precisely 131071 bytes) cannot be download from zope portal since the administrator move it over apache. I mean, I can download a pdf file of 8 Mb from Plone, but I cannot download any file from a LocalFS area bigger than the value above. This issue sounds very unusual to me and I am not completely sure if I am reporting fine, specially because I am not the zope server administrator, I just have a plone account to develop a product. I hope someone else can help me here, any hint would be very welcome. Many thanks in advance. Cheers and Happy New Year 2007.

resolved: acl_users
by Sean Duffy 03 Jan '07

Hi, Andreas has pointed out that my personal os.bias module has prevented me from producing pythonically correct code. Please note the replacement of z1[:-1] with z1.strip() below. Then an external method (LoadUsers) to read it: def LoadUsers(self): f=open('/var/lib/zope/Extensions/usr_pwd.txt', 'r') y=f.readlines() return y And a script (user_load): ## Script (Python) "user_load" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## y=context.LoadUsers() p=[] for x in y: z=x.split(' ') z0=z[0] z1=z[1] z1=z1.strip() acl = container.restrictedTraverse( '/foobar/acl_users' ) acl.userFolderAddUser( z1, z0, p, '' ) return 0 Sean

solved: acl_users
by Sean Duffy 03 Jan '07

03 Jan '07

Hi, Thanks to Robert & Alexis I have a working solution: First I made a text file (usr_pwd.txt) in the form of password space username, and placed it (temporarily) in the Extensions directory. Then an external method (LoadUsers) to read it: def LoadUsers(self): f=open('/var/lib/zope/Extensions/usr_pwd.txt', 'r') y=f.readlines() return y And a script (user_load): ## Script (Python) "user_load" ##bind container=container ##bind context=context ##bind namespace=_ ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title= ## y=context.LoadUsers() p=[] for x in y: z=x.split(' ') z0=z[0] z1=z[1] z1=z1[:-1] acl = container.restrictedTraverse( '/foobar/acl_users' ) acl.userFolderAddUser( z1, z0, p, '' ) return 0 Sean

attribute-less object(assign or del)

Module None, line 45, in copy_of_stats_output_branch <PythonScript at copy_of_stats_output_branch> Line 45 for j in self.sql.sqlGetStatDetailsSum(date1=i.date, branch1=i.branch, category1=i.category, timeCheck1=k): if str(j.sum_renewals)== 'None': line 45 --> j.sum_renewals = 0 elif str(j.sum_registrations)== 'None': j.sum_renewals = 0 elif str(j.sum_hours)== 'None': j.sum_renewals = 0 elif str(j.sum_reference)== 'None': j.sum_renewals = 0 When I have values returned by the sql call it works fine but as soon as I get to a field that has a 0 in it then I get an error... As far as I can tell I'm doing the assignment correctly ... what's wrong here? Kate

Exploring non always repeating tracebacks in test case
by Marco Bizzarri 03 Jan '07

03 Jan '07

Hi all. I'm trying to explore the possible reasons behind some strange traceback which on some conditions (unknown to me at the moment) appears while running my ZopeTestCases. When I run all my tests, sometimes I get no error. Sometimes I get from 3 to 5 tracebacks, all related to the same part of the code. Here is one of those tracebacks. ERROR: testActIntegration.DeterminationTestCase.testProposal ---------------------------------------------------------------------- Traceback (most recent call last): File "testActIntegration.py", line 106, in testProposal draft.fromScratch(AUTHOR) File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Acts.py", line 1298, in fromScratch self.makeDocumentUsingData() File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Acts.py", line 1085, in makeDocumentUsingData 'application/pdf') File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Documents.py", line 676, in setBinaryFileType self.updateData(file, content_type) File "/var/local/zope27/paflow/zeoclient/Products/PAFlow/Documents.py", line 558, in updateData data, size = self._read_data(file) File "/var/local/zope27/base278/lib/python/OFS/Image.py", line 518, in _read_data get_transaction().commit(1) File "/var/local/zope27/base278/lib/python/ZODB/Transaction.py", line 241, in commit ncommitted += self._commit_objects(objects) File "/var/local/zope27/base278/lib/python/ZODB/Transaction.py", line 356, in _commit_objects jar.commit(o, self) File "/var/local/zope27/base278/lib/python/ZODB/Connection.py", line 452, in commit dump(state) File "/usr/lib/python2.3/copy_reg.py", line 69, in _reduce_ex raise TypeError, "can't pickle %s objects" % base.__name__ TypeError: can't pickle function objects Of course, there is a lot of my code here, so basically I'm not asking about the problem, but on how I could further explore the problem (aside from putting a conditional break in the code and run the tests until it is activated). Another (related) question is related to the following snippet, from OFS.Image: File "/var/local/zope27/base278/lib/python/OFS/Image.py", line 518, in _read_data get_transaction().commit(1) Here we have therefore a subtransaction committed. This worries me a lot, since my code deals, at the same time, with PostgreSQL database and ZCatalog. In the ZCatalog, the subtransactions where disabled since they were not compatible with PostgreSQL. I think there is a similar issue with subtransaction in Image... am I wrong?

The product I made isn't in the product management page
by Allen Huang 03 Jan '07

I'm using Zope 2.8.8 and I trying to make my own product. Whenever I make a product with errors in the python coding, I could see my product name registered in the product management page. But when I fix all the error, the product disappears; it not in the product management page or the add menu. What is the problem here? here is my coding __init__.py-------- ------------------- import helloModule def initialize(context): context.registerClass( helloModule.helloClass, permission="Add Hello Object", constructor=( helloModule.manage_addHelloForm, helloModule.manage_addHello ) ) helloModule.py-------- ------------------------ def manage_addHelloForm(self): " Form for adding a Hello Object " return """ <html> <head> <title></title> </head> <body> <form method="post" action="./manage_addHello"> <input type=text name=id> <input type=submit value="Add Hello"> </form> </body> </html> """ def manage_addHello(self): " Method for adding a Hello Object " newHello=helloClass(id) self._setObject(id, newHello) return self.manage_main(self, REQUEST) class helloClass: meta_type='Hello Object' def __init__(self, name='World'): self.name=name def saySomething(self): return "Hello, " + self.name def edit(self, name): self.name=name __________________________________________________ Do You Yahoo!?

thanks for repling Marco. I'm using a window version of zope and linux command 'zopectl fg' doesn't work. what is the forground command in windows?

[zope 2.7-2.8] Howt to alow import module in Python script
by Mihamina Rakotomandimby 02 Jan '07

02 Jan '07

Hi, As far as I know, if I want to use/import a module (let's say urllib*) in a Python Script (the restricted ones), I have to use external methods and then use it in the Python script. I remember I saw in a zope related Mailing List (CPS, Plone, Zope...) I cant list somewhere the modules I want to be loadable from restricted Python script. Would you remind me the place I could do it please? Thank you. I mostly need urllib, ftplib, re, HTMLParser,...
