StructuredText & LocalFS in Python Script
by Elena Schulz 02 Aug '02

02 Aug '02

Dear List, having the following objects: sourceFolder points to a LocalFS-Instance, fileId points to a file in the LocalFS-Instance, and convert_nonascii_1(string) is just a method to exchange some text in string. in DTML I can do the following: <dtml-var "convert_nonascii_1(_.str(_.getitem(sourceFolder, 1)[fileId]))" fmt=structured-text> But how is it done in Python Script? if myLFSname is the name of the LocalFS-Instance and file.txt the name of a file in the LocalFS-Instance this works fine: context.myLFSname['file.txt']() But as soon as I try to do it with sourceFolder and fileId, I get only errors even if the Script can resolve both. Does anybody know why? And how do I use structured Text in Python Script as in DTML: <dtml-var my Var fmt=structured-text> Thanks a lot for your help, Elena

Beginner question: user defined variables
by Michael Guerrero 02 Aug '02

02 Aug '02

Hello, This my first zope project. I am trying to declare a variable called 'tot' for a total field. Within a dtml-in I would like to add a value to this variable. Then display the value of 'tot' after the dtml-in finishes. I have tried the following ( I have placed my comments at the end of each line): <table> <dtml-in sql_billtest> <dtml-call "REQUEST.set('tot','tot' + charge_amt)"> -- here is where I try to declare/add to the variable 'tot' <tr> <td><dtml-var invoice_num></td> <td><dtml-var item_type></td> <td><dtml-var charge_amt fmt="%0.2f"></td> -- for each row I want to add this field to 'tot' <td><dtml-var tap_num></td> <td><dtml-var subscriber_name></td> </tr> </dtml-in> <tr> <td><dtml-var tot></td> -- now I want to display the value of 'tot' </tr> </table> When I try this I get 'cannot add type "float" to string'. Is there a way to declare 'tot' as a float? Is this the correct way to do this? I have the 'Zope Bible' but it doesn't have any good examples. One way a was able to get the total was to put another dtml-in after the first and user the 'total' statistics variable. <dtml-in sql_billtest size="1"> <tr> <td><dtml-var total-charge_amt fmt="%0.2f"></td> </tr> </dtml-in> I do not prefer this way. Since 'sql_billtest' is a database query I do not want to query the database twice (once for the detail and once to get the total). Thanks for your help. Mike

session within standard_error_message
by KevinL 02 Aug '02

Can you set values inside the session object from within standard_error_message? I note that doing a request.RESPONSE.redirect requires a "lock=1" arg, I'm wondering if session variable setting suffers similar problems or not. Reason I ask is, I have an app that tries to set session variables within the standard_error_message, and debug indicates the variables are there within that transaction, but gone on the next request from the browser.

Log File Analysis Software
by James Bragg 02 Aug '02

02 Aug '02

Hello everyone! I'm attempting to get Sawmill (www.sawmill.net) working with Zope log files. First, Is anyone using Sawmill with Zope? If you are would you care to share your log definition file with me :o) Second, what module is responsible for writing the Z2.log file? Is this part of Medusa, ZServer, or Zope? Third, does anyone know where I can get the field definitions for the Z2.log file. I can't seem to find any docs on it. Almost finally, what other log file analysis tools are people using with Zope? Would you care to share your opinions? Finally, If I'm being blatantly stupid here, please forgive me I'm still a newbie :o) Thanks in advance for any advice or encouragement you have to offer. -james

TIA You might want to check out the patch to SQLgroup made by Andy Dustman. I posted a similar question a couple of weeks ago, and got this reply: http://groups.yahoo.com/group/zope/message/94058. I've installed the two patch files (but not SQLBlender itself), and it's working flawlessly. I now have ZSQL methods for updating that look like: update reg <dtml-sqlgroup set noparens> <dtml-sqltest iplayerid type="int" op="eq"> <dtml-comma> <dtml-sqltest ilastteamid type="int" op="eq" optional> <dtml-comma> <dtml-sqltest clastteamtype type="string" op="eq" optional> <dtml-comma> <dtml-sqltest cotherdesc type="string" op="eq" optional> <dtml-comma> <dtml-sqltest itryoutage type="int" op="eq"> <dtml-comma> <dtml-sqltest cpostip type="string" op="eq"> </dtml-sqlgroup> where iid = <dtml-sqlvar iid type="int"> ___/ / __/ / ____/ Ed Leafe http://leafe.com/ http://foxcentral.net _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

MailHost.send sends empty message
by John_Knutson＠candle.com 02 Aug '02

02 Aug '02

I am trying to send an email message from a Python script but all gets received is an empty message . I've tried using a variable insetad of a string constant but that doesn't make any difference. context.MailHost.send ("text" , mto=address, mfrom ="cassini(a)candle.com", subject=subject, encode=None) On a related subject, how would I construct a list of "to" addresses? Would it be an array or some sort of concatenated string? If the latter, how would it be delimited? I'm using Python here because I can't figure out how to do this (simply) with a Page Template so if anyone could point me at or send me such an example I'd be very grateful. Cheers, John Knutson Candle Corporation

Multiple inheritance and tree data structure problems
by Manuel_Montejo＠apb.es 02 Aug '02

02 Aug '02

Hi, I'm developing a Zope product, ServiceProduct, that behaves as a Node in a Tree data structure. The class hierachy is the following [<--- : extends ; <- - - : implements] Base <---Tree <- - -TreeImpl Base <---- TreeNode <- - - TreeNodeImpl Base <---- Service Implicit,Persistent,RoleManager,ObjectManager,PropertyManager,Item <---- ProductBase ProductBase, TreeNodeImpl<---- ServiceProduct TreeNode<- - - ServiceProduct Service<- - - ServiceProduct So, when I create an new instance of ServiceProduct using the ZMI I found a problem with the constructor. The error message is "unbound method __init__() must be called with instance as first argument" and the code is def __init__(self, id): ProductBase.__init__(self,id,'') try: TreeNodeImpl.__init__(self,id) except Exception, e: print 'Problems with TreeNodeImpl constructor', e # do TreeNodeImpl initialization here if fails self.setNombre( id ) self.parentNode = None self.children = [] self.tree = None I hope that doing the TreeNodeImpl initialization in the except clause will solve this problem. Then, I add child ServiceProduct objects to the tree hierarchy but it seems that the references between parent and child objects change when new calls to the object are done (I use a DTML page for displaying hierarchy info). Even worse, the ProductBase has a method hashCode that shows instance info def hashCode(self): id = str( self ) id = id.replace( '<', '_') id = id.replace( '>', '_') id = id.replace( ' ', '_') return id returns two different results when is called from a DTML page, (sometimes the first and other times the second), BUT I have created only one instance of the object. Finally, I have tested the TreeImpl, TreeNodeImpl outside Zope and it works without any problems. Any idea of where is the problem? The 'constructor problem' is related to the 'references losing' problem? Any help with will be apreciated. Best regards, Manu
