Hi, It seems that the Zope developer guide at http://www.zope.org/Documentation/ZDG is suited for Zope 2.4.x +. I need the one that's suited to Zope 2.3.3 and did not find it. Any clue ? Thanks in advance --Gilles

ExternalEditor: Many Thanks

Casey, ExternalEditor is already shaping up for my vote as Zope developer application of the year. This is a huge step forward. Thank you for this fine contribution. And thanks to you, Gabriel, for adapting the helper application to work with the Windows. It works just fine on my Windows 98 system with Opera 6.02.

Interesting namespace observation
by Roché Compaan 27 May '02

27 May '02

I have a method in the root of my application called "getProxies" that queries a catalog for a given metatype. I have a folder in the root called "Platforms" with a method called "selectInstance" that renders a series of checkbox tags. I call "selectInstance" method from an adjacent folder with <dtml-with Platforms> <dtml-var selectInstance> </dtml-with> This is how this method look at first: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3"> <dtml-in getProxies('Platform') sort="Name" prefix="platform"> <dtml-let item="platform_item.id" display_item="platform_item.Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> Doing the above gives a key error for "getProxies", however if I move "getProxies" into the let tag it does _not_: <dtml-let control_set="setControl(_, 'PlatformID')" control_name="control_set[0]" control_value="control_set[1]" control_type="'checkbox'" num_columns="3" proxies="getProxies('Platform')"> <dtml-in proxies sort="Name"> <dtml-let item="id" display_item="Name"> <dtml-var inputTag> </dtml-let> </dtml-in> </dtml-let> It seems like <dtml-let> is doing something with the namespace that makes it impossible for the subsequent <dtml-in> tag to find the "getProxies" method in the root. Any ideas why? -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za

Sequencing question
by David Williams 27 May '02

27 May '02

Ooops, sorry, sent this by mistake before I had finished .... try again Hi all First-time posting from a Zope newbie ... hopefully someone can help I have defined a number of ClientProjects within Zope and I am trying to display these in a number of ways, filtered by object property values. So, for example, I want to display all client projects, or perhaps only those marketing projects, ie. where the marketing property has a value. I display the client project titles in an HTML table, 3 per row, and for all projects this works OK - I use the sequence-number to control the table formatting, and the index sequence is unbroken when all objects are displayed. My problem arises when I have a sub-set of projects to display, because the sequence-number and sequence-index values still seem to relate to the full set of objects. So if the sub-set only comprises objects 7 & 8 (eg the only marketing projects), the sequence-number is not reset automatically to 1 & 2 - they remain at 7 & 8. The same applies to the property sequence-index. So the way I check for the 3rd item in the collection, using sequence-number, does not work becuase the sequence number is not guaranteed to start at 1. I think I need a Python function to query and return a subset of objects, but how do I go about writing such an external method ? And how does it access my Zope ClientProject objects ? I also looked at using dtml-let and trying to keep a separate count ticking along, but seem to run into trouble with the variable's scope. Or is there an easier way around this that I have missed ? Any ideas ? Thanks in advance Dave

Re: [Zope-dev] can't remove ExternalEditor
by Paolo Galati 25 May '02

25 May '02

You must have access to file system, first remove the ExternalEditor product from ZMI, then stop zope and remove all .pyc from zope folder, finally remove ExternalEditor product from Products folder where ExternalEditor was installed. Restart zope and the ExternalEditor is no longer needed by zope hope this is usefull for you, excuse for my english. bye paolo. -------------------------------------------------------------- Paolo Galati - Developement Area [ n o z e S.r.l. ] - Soluzioni open-source Via Giuntini, 25 int.29 - 56023 Navacchio - Cascina (PI) Tel +39 (0)50 754380 - Fax +39 (0)50 754381 Email: paolomail(a)noze.it - Web: http://www.noze.it --------------------------------------------------------------

Python, Zope and pymalloc
by Dario Lopez-Kästen 24 May '02

24 May '02

hello! Is anyone using zope with a python that is not configured with --without-pymalloc ? I understand that there is still a conflict with ExtensionClass unless python is cfg'd --without-pymalloc?

can't remove ExternalEditor
by Christopher N. Deckard 23 May '02

23 May '02

How do I completely remove ExternalEditor from the installed Products? It seems as though once Zope has been started with the ExternalEditor product, it depends on it and you must continue to have it installed. I don't plan on not using the product, but I want to be able to safely remove it (or any product) if it causes troubles.

redundant permissions
by Christopher N. Deckard 23 May '02

23 May '02

I'm trying to collect ideas on improving the representation of permissions in the security tab in the ZMI. I was wondering if anyone knows why there are two permissions "Open/Close Database Connection" and "Open/Close Database Connections". This seems like a redundant duplication of permission usage. :-) There are two lines in AccessControl/Permissions.py which define these. Most of the products which need this permission use the "Open/Close Database Connections" version. The only thing that I find that doesn't is in Shared/DC/ZRDB/Connection.py, line 51 in zope 2.5.1. Should I submit a patch to the collector for this? Or is this done on purpose? -Chris -- -------------------------------------------------------------------- Christopher N.
