Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

creating a data edit form
by Tom P. Allred 28 Jan '04

28 Jan '04

Hi, (It is not my intent to cross post but I sent this to the Formulator list yesterday and still haven't seen it show up.) I'm pretty new to Zope so please speak slowly and use small words. :o) Several months ago I started a small learning project in Zope using Formulator. I got to the point of successfully creating data input forms, storing the entered data in ZODB objects, cataloging the objects, and using the catalog to retrieve and display data from an object. Life intruded and forced me to lay the project aside for a couple months but now I'm ready to pick it back up. I'm hoping someone can help kickstart me into the next step which is providing a data edit form to let the user change previously stored data. Currently, to show previously saved data, I give the user a drop-down box with all the record keys, let them select a key and click Submit, then use a Python script to query the catalog and print/return the selected fields (property values) to a display page. What I'd like to do is return the selected fields into the input form so the user can edit them. Here is the ZPT code (taken from a forgotten example) used to display the original input form. <form name="dataform" method="post" action="formresult.zpt">  <table tal:define="form here/dataform" align=left>  <tr tal:repeat="itemz here/dataform/get_field_ids">  <span tal:define="fieldobj python:form.get_field(id=itemz)"> <th align="left"> <font size=4> <font face="verdana">  <b tal:content="fieldobj/title">Field Display Label</b> <b>:</b> </font> </font> </th> <td>  <input type="text" name="itemz" tal:replace="structure python:fieldobj.render()"> </td> </span> </tr>  <tr cols="*,350,*"> <td> </td> <td align=left><input type="submit" value=" Submit "></td> <td> </td> </tr> </table><br> </form> Could someone please explain how to get the fields retrieved by my Python script into the form so the user can change them?

Well, we still run out of memory, and then it's useful to know why. :) Caring about memory usage is caring about (one kind of) scalability. I realize I can't change this aspect of Python, and it's not that critical to know if you can deduce memory usage from pickle sizes (like you mention).

Any chance of seeing these changes in the core? [...] The remainder of my use cases can be currently best supported by using a debugger + DocFinder, I agree, although I think there's still a need for an admin tool that lets you easily view and browse (multiple) objects, independent of if they catalogaware or has an ZMI interface. I'll think so more about it. Thanks for all the help. -- Bjorn

security (edit) problem for ttwtypes
by vogel＠glue.ch 14 Jan '04

14 Jan '04

I discovered a security problem in my plone/zope installation for every ttw-type. environment: - plone version 1.0.5 - os: windows 2000 - installed products: ttwtype, zopexmlmethods - created ttwtype 'ttwTypnamesFoo' in folder /myPloneFolder 1) at the root folder of my plone instance, I created a role A with permissions: a) Access session data und b) Access Transient Objects 2) I created user 01 with role A - correct: the user 01 never gets to see the tab with the edit-action - that's why on points 3) and 4) the access to the edit-form is done by typing the url directly in the url-field of the browser. 3) correct: - if user 01 wants to edit an object of type document (e.g. /Plone/index_html), the edit-form will be shown, but the user cannot save it. (-> msg: you are not allowed....) - url was: http://........../Plone/index_html/portal_form/document_edit_form 4) problem: - if user 01 wants to edit an object of a ttwtype (e.g. /myPloneFolderttwTypnamesFoo), the edit-form will be shown, and the user is ALLOWED to save it!! - url was: http://......./myPloneFolder/ttwTypnamesFoo/portal_form/ttw_edit_form any ideas how I can restrict the edit-and-save-access to my ttwtype objects? thanks for every input, david.

Sessiondata in SQL
by Heimo Laukkanen 08 Jan '04

08 Jan '04

Hi ya all, I wondered about integration applications in php better with applications in Zope and thought about even handing over sessiondata via sql. What is the contemporary way to have sessiondata in SQL RDBMS and are the drawbacks in it too much to even think about it - compared to using the ram based sessiondata? I tried to google but did not find that much information about whether people had written their own sessiondatamanagers or sessiondata storages to do this - hence the question. -huima

TextIndexNG Similar search HELP!!!
by Joel Jensen 01 Jan '04

01 Jan '04

I am trying to do a SQL LIKE query on a lastname attribute of a zclass. ie. show me all the lastnames LIKE 'cronkyte' should return cronkite... I am trying to use TextIndexNG to do this. I need to get the Similarity search part of TextIndexNG working. I can create a working TextIndexNG using the Zope management interface, this index will return EXACT matches, but not similar ones. However the ZMI does not appear to have a way to activate the Similarity search. How do I use the Similarity search in a query? Thanks I am using zope 2.6.1 mandrake linux 9.1 python 2.1.x Joel Jensen
