Hi, When two users enter their login name & password and press enter simultaniously,the first who entered among the two gets the following error. Error Type: SyntaxError Error Value: unexpected token sequence.near :: 'of_que\012from noq'*'' ******************************* current state = 277 expects: '*', ';', ')', 'ORDER', ('nomatch1',) current token = ((-6, 'FROM'), 'FROM') The above error is while entering the Zope .Again If they fill the form & click submit button simultaniously.The following error occurs for the user who presses submit button first. Error Type: SyntaxError Error Value: unexpected token sequence.near :: "\012Q_name = 'q24'"*'' ******************************* current state = 231 expects: 'EXCEPT', '+', ')', 'HAVING', '-', 'UNION', 'AND', 'GROUP', '*', ';', 'OR', 'ORDER', 'INTERSECT', ('nomatch1',) current token = ((-6, 'WHERE'), 'WHERE') Both users will be accessing the same database. I don't know why this error occurs.If we refresh the error occurred page then it doesn't give error(that time no other user was pressing submit button). In the product which i have implemented multiple users will enter & fill the forms simultaneously. waiting for your immediate reply. bye, jacintha

How to maintain an up-to-date mirror site in Zope? (not-so-newbie question!) question!)
by Bowyer, Alex 14 Nov '00

14 Nov '00

Here is the situation, can you offer advice? Machine A is running a Zope server for a wide-area network in Company A. This is an Intranet site which changes regularly. Machine B serves a separate wide-area network in Company B, and Company B employees need access to Company A's intranet. The link between Machine A and Machine B is too slow/low-bandwidth for all of company B's employees to access A's intranet directly. Therefore we want to have a Zope server on Machine B with a mirror copy of the Company A intranet. The problem is, how can we keep this mirror copy updated on a daily basis? Ideally we need an automatic process to run each night and update the mirror on B. The ideas I had were : 1) stop B's Zope server, copy across data.fs and restart B. But can this be done automatically? 2) somehow keep a log of changes made in A, and at the end of day, export the changed files, import them on B, overwriting the originals. Can this be done in Zope code? Can this be automated? Does anyone have any thoughts/opinions on these ideas? Or does anyone know of a better way, perhaps an existing Zope package or solution?

Form variables with same name as folder names
by Burwell, Becky <burwell＠parc.xerox.com> 13 Nov '00

13 Nov '00

Hi. I am new to using Zope and just got stuck on the following problem. I am trying to use forms with an SQL database. I have a form with checkboxes and I use variables like FOO to capture the value. For example: <input type="checkbox" name="FOO" value="1"> The form has a post with the action to call a DTML document. In my DTML document I call a Z SQL Method called InsertMethod with REQUEST as the argument, for example InsertMethod(REQUEST). My Z SQL Method InsertMethod has arguments including FOO="" And then in the body of the Z SQL method I have: <dtml-if FOO> {code to insert into a database table} ---------------- This working UNTIL I created a Folder named FOO. Then the value of FOO in the Z SQL method seemed to be the FOO folder and not FOO from REQUEST. My workaround was to call the variable FOOCHECKBOX. Two questions: 1) the ZSQL manual, http://www.zope.org/Documentation/Guides/ZSQL-HTML/ZSQL.1.4.4.html, says that the first lookup should be variables in HTTP_REQUEST. So why is FOO referring to my folder FOO? 2) is there some way I could have referred to the variable FOO in my Z SQL method without resorting to renaming the variable in my form? Thanks! *becky*

Calling obj. in index_html

I had to catch myself. expr="Bad Jimbo" I guess calling it versus inserting it achieves the same results. Just to clarify this would render a string "_['ftp']" right? -Jimbo

DTML and SQL question...
by zope 13 Nov '00

13 Nov '00

Hi. I want to test if there is some data in a table. If so, I want to perform some action, otherwise I wan't to print out a message. (<dtml-if>..<dtml-else>..</dtml-if>) My SQL statement is something like: Select count(*) from my_table where my_field = something What DTML code do I need to perform that if-statement? Something like the following does not work :-( <dtml-if "genericSQL(SQLStatement='Select count(*) from my_table where my_field = \'0\'') == 0"> YES! There's some data! <dtml-else> no records found! </dtml-in> Thanks for any help. Greetings, Marc Ludwig Luxembourg

Hi Andy, Sorry to question you, but from what I understand <dtml-with "ftp"> <dtml-var index_html> </dtml-with> is "Bad Andy" Should be <dtml-with ftp> <dtml-var index_html> </dtml-with> Seems he wants to call the object and not the string right? I'm just testing if I learned anything about Zopemantics yet. -Jimbo

Monkeying with the Zope database
by Steve Jibson 13 Nov '00

13 Nov '00

I've been toying with the Zope database and I'm probably alomst to the point where I know enough to be dangerous. I am trying to make a few changes to the stuff in the Zope database without actually running Zope. Here's what I'm tring to do: 1 - Create a new user in the top level acl_users folder 2 - import a file "login.zexp" into the top level folder (login.zexp has been copied to the import directory) Here's some code I've written: ------------------ import sys sys.path.insert(0, '/home/zope/lib/python') import Zope appRoot = Zope.DB.open().root()['Application'] # create a new user appRoot['acl_users']._doAddUser(name='ThisWebSiteIsMine-SoThere', password='pw', roles=['Manager'], domains=[]) get_transaction().commit() # login as that user owner = appRoot['acl_users'].getUserById('ThisWebSiteIsMine-SoThere') Zope.AccessControl.SecurityManagement.newSecurityManager(None, owner) # import login.zexp and take ownership appRoot.manage_importObject('login.zexp', set_owner=1) get_transaction().commit() ------------------ Here's the resulting traceback: ------------------ Traceback (innermost last): File "go.py", line 22, in ? appRoot.manage_importObject('login.zexp', set_owner=1) File "/home/zope/lib/python/OFS/ObjectManager.py", line 526, in manage_importObject self._setObject(id, ob, set_owner=set_owner) File "/home/zope/lib/python/OFS/ObjectManager.py", line 267, in _setObject object.manage_fixupOwnershipAfterAdd() File "/home/zope/lib/python/AccessControl/Owned.py", line 273, in manage_fixupOwnershipAfterAdd self.changeOwnership(user) File "/home/zope/lib/python/AccessControl/Owned.py", line 166, in changeOwnership new=ownerInfo(user) File "/home/zope/lib/python/AccessControl/Owned.py", line 297, in ownerInfo db=user.aq_inner.aq_parent AttributeError: aq_inner ------------------ It appears to be dying while trying to set the ownership. There's a good chance that I'm going about this all the wrong way (I'm new at this stuff). Any help to fix up what I've tryed or new ways to approach the problem will be appreciated. Thanks, Steve
