[Zope-dev] I have two question. Would you help me please.
Hello. First of all Happy New Year!This is korea. I am a zope student. On studying I have two question.Q1. How call the ZSQLMethod into script python.Firrst I write the script python named 'myscript' and the ZSQLMethod named 'mySqlMethod' myscript (script python)# Example code:# Import a standard function, and get the HTML request and response objects.from Products.PythonScripts.standard import html_quoterequest = container.REQUESTRESPONSE = request.RESPONSE # Return a string identifying this script. val = context.mySqlMethod() print valreturn printed mySqlMethod (ZSQLMethod) select * from bbs1 (:bbs1 is the table name of the DB) How call the 'mySqlMethod'(ZSQLMethod) into 'myscript'(script python) and how display the query results of ZSQL Method called into script python ?I called mysqlMethod into the above myscript( val = context.mySqlMethod()). But I failed. Q2. How to display the list type data. myDTMLMethod(DTMLMethod)** dtml-var standard_html_headerdtml-var "myScript()"dtml-var standard_html_footer myscript (script python)** # Example code:# Import a standard function, and get the HTML request and response objects.from Products.PythonScripts.standard import html_quoterequest = container.REQUESTRESPONSE = request.RESPONSE list1=[] vala = 100valb = 200 list1.append(vala)list1.append(valb) return list1 I worte DTMLMethod named 'myDTMLMethod' and script python named 'myscript'Above myscript return the list type data. Then how display the returned list type data into the myDTMLMethod?The question part is dtml-var "myScript()"But I failed.How could Iresolve thses questions?Help me!!Thank you very much.

Hi, Q1. How call the ZSQLMethod into script python. take a look at http://www.zope.org/Members/spinwing/ZSQL_Results Q2. How to display the list type data. You should give us more info, errors or trace back. -- Vincenzo Di Somma - Responsabile Ricerca e Sviluppo - Icube S.r.l.

[Zope-dev] Big problem.
Urgh! While trying to get Zope 2.5.0b3 working I accidentally started a 2.5.0b3 ZEO client on a Zope 2.4.3 ZEO server. Doing this caused some stuff (Sessions?) to be added to the database. When the live 2.4.3 ZEO client stopped, it wouldn't restart with the following traceback: -- 2002-01-10T21:27:44 PANIC(300) z2 Startup exception -- 2002-01-10T21:27:44 ERROR(200) ZODB Couldn't load state for '\x00\x00\x00\x00\x00\x00\x00\x02' Traceback (innermost last): File /data/www/Zope.6/src/Zope-2.4.3-src/lib/python/ZODB/Connection.py, line 544, in setstate ImportError: No module named Sessions.SessionDataManager Traceback (innermost last): File /data/www/Zope.6/Zope/z2.py, line 564, in ?

[Zope-dev] Re: [ZODB-Dev] Big problem.
I don't know if a tool exists either. I think something quick could be hacked together, but I doubt I'd have time to do it anytime soon. I don't know if you up for some programming to accomplish this goal or not. There are a couple of ideas I have along these lines in case you or someone else can pursue them. There's a tool called fstest.py in two places in CVS: Zope/utilities/ZODBTools and StandaloneZODB/Tools If you run it with a -vv argument it will show you all the individual transactions an objects. It prints a transaction id, and could be modified to convert those transaction ids to timestamps. From the timestamps and oids, you could probably figure out the last good transaction. You can use transactionalUndo() on every transaction id following the last good one. You might be able to go into the storage and truncate it at the last good transaction. You'd need to blow away the index, too. This sounds risky, but might be the simplest solution. (Backup the file first :-).

Re: [Zope-dev] Re: [ZODB-Dev] Big problem.
Darn. At this point you can try just hacking off bits of file at the end of a *copy* of the Data.fs you have by using the trunctate method described in Itamar's howto. Start small and just cut off pieces at the end of the file until you're able to start Zope again. You might lose some data this way but at least it will start. After you get it to start, and you've lost data, you can also use (painfully slow) binary search to pinpoint where exactly you need to truncate on further copies. I am working on preventing this on the 2.5 branch now. It's ironic that I got on Jeremy's case for something like this not too long ago. ;-) Mea culpa. - C Andrew Sydelko wrote: Chris McDonough wrote: Try the original tranalyzer here instead: http://www.zope.org/Members/tsarna/Tranalyzer That's better, but it bombs out part way thru: Traceback (most recent call last): File ./tranalyzer.py, line 333, in ? main(sys.argv) File ./tranalyzer.py, line 325, in main t = Transaction(f, off, refs) File ./tranalyzer.py, line 170, in __init__ self.obs.append(Record(f, refs)) File ./tranalyzer.py, line 201, in __init__ self.prevrec = f.u64() File ./tranalyzer.py, line 121, in u64 self.checkleft(8) File ./tranalyzer.py, line 87, in checkleft raise 'Not enough data left, %d %d' % (self.left, n) Not enough data left, 0 8 Here are the last few things that it spit out: TID: 33E2AAB7A0AA1D5 @ 449542140 obs 1 len 7404 (status 'p') By david.s.carmichael.1 /people/david.s.carmichael.1/tutorial/Building My Pictures Page/manage_undo_transactions Undo 2001/07/24 14:23:12.6358 US/Eastern /people/david.s.carmichael.1/tutorial/Building My Pictures Page/manage_edit OID: 7e12a len 7120 TID: 33E2ABB4126FA3C @ 449549560 obs 2 len 1234 (status 'p') By david.s.carmichael.1 /people/david.s.carmichael.1/tutorial/manage_addVersion OID: 7cd46 len 798 OID: 86081 len 261 0 8 ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope ) ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
Re: [Zope-dev] Re: [ZODB-Dev] Big problem.
Note that untarring the attached products into your 2.4 Products directory should allow you to start 2.4 up with the Data.fs from your foray into 2.5 without needing to truncate anything. At that point you should be able to delete the session_data_manager, temp_folder, and browser_id_manager objects and restart without the faux products.

Re: [Zope-dev] Re: [ZODB-Dev] Big problem.
Whoops, that wasn't quite enough. Also do this:
Create the following Python file as unscrew.py in your 2_4/lib/python
directory and run it.
import Zope
app = Zope.app()
app._delObject('session_data_manager')
app._delObject('browser_id_manager')
app._delObject('temp_folder')
del app.__before_publishing_traverse__
get_transaction().commit()
Note that if you've got access rules or site roots in your root dir,
this will blow those away and you'll need to recreate them.

I didn't think you could have more than one

security.setDefaultAccess('deny')
security.setDefaultAccess({'meta_type': 1})
The last 'setDefaultAccess' statement in a class will define the actual
behaviour, i.e use only one.
But otherwise, you would have to list all attributes of the class in the
dict of a single statement, wouldn't you?
No, all attributes that aren't in the dict are private.
Thanks, Wolfram. That was very informative.
This will let classes that use declarative security have a deny by
default policy, while still allowing access to certain attributes for
backward compatibility.
