So what you are implying is that even trusted users can make mistakes as allowing non trusted users to do scripting shouldn't be done. When the trusted user has got his script working properly can he then remove the restraints? What happens when I really want to make very large xranges etc or use those rather useful things which are presently forbidden. Yes, I can use External Methods if I have access to the machine, but those 'trusted' scripts could be just as easily handled by a 'Trusted Python Scripts' Zope object which didn't have all the rather (as you say yourself) pointless safety checks. Then I could handle the safety issue in Zope and not in the base OS.

I am trying to change the colour of links dynamically using dtml.
However, I cannot find the right incantation to change my links using an
inline style except for
A
I really would like to be able to set the link, active and visited
colours.
I can do this using a class
eg
<!--
A:link, A:visited, A:active {font-weight: bold}
A.badLink:link, A.bad:visited, A.bad:active {color: red; font-weight:
bold}
-->
.

[Zope] preventing acquisition
I have some folderish Zclasses which have index_html methods to implement a UI. I would like to inhibit acquisition of these. So if I have a path /A/B/C I would like to inhibit the behaviour that allows me to view /A/B/C/A and /A/B/C/A/B/C etc. to inhibit the first I can put something like You're not supposed to be looking at in my index_html, but this doesn't work for the second case. Is there a generic way to do this? -- Robin Becker ___ Zope maillist - [EMAIL PROTECTED] 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 )
[Zope] two things at once?
I want my form button X to cause some data to be uploaded to the user. So I make the action call a method that sets up the right response content type etc and the upload goes well. 1) Can I verify that the action happened? 2) how can I force the page containing the original form to be refreshed so that I can change button etc. -- Robin Becker ___ Zope maillist - [EMAIL PROTECTED] 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 )
[Zope] overriding manage methods
In my Z-Class I would like to hook various standard methods in a dtmlish way. The frame work would call my dtml method say manage_delObjects and within that method I would like to call the original manage_delObjects. I guess this must be a very standard requirement as I see that there are methods called afterAdd and beforeDelete etc in the object manager. I just don't know the proper namespace magic to override and eventually call these. -- Robin Becker ___ Zope maillist - [EMAIL PROTECTED] 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 )

A and B both have class specific methods A_init and B_init to initialise specific bits of each. The product P has some methods eg M defined which are useful to both A and B. 1) How do I make the add methods behave identically whether I invoke as /dir/manage_addProduct/P/A_add or when I invoke from the manage add interface. I want to know the meta_type of the actual location where the product will appear not the factory's meta_type. 2) When I attempt to call B_add from inside A's private method A_init I seem to see a completely different context from when I call B_add directly on an instance of A. 3) I suppose this is related to the fact that inside A_init (the private method) I don't seem to see the same context as in A_add, ie the method M is visible in A_add, but not in A_init. How do ZClass contexts and the product context relate? -- Robin Becker ___ Zope maillist - [EMAIL PROTECTED] 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 )

I would like to add properties in a property sheet, but cannot find a neat way to see the properties on the base object and on the propertySheet. So I would like my properties to show id title and the properties on my basic properties sheet. I can easily add properties directly to the object during the Thing_add and Thing_addForm and these appear on the properties tab for added objects. How do I get a tab for the property sheets? -- Robin Becker ___ Zope maillist - [EMAIL PROTECTED] 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 )

Re: [Zope] Using ReportLab with Zope
In article <01bfc278$7c017e80$[EMAIL PROTECTED]>, Richard Folwell <[EMAIL PROTECTED]> writes On the reportlab site we have several pages which can be viewed as PDF. The PDF & HTML versions are generated in parallel from a common source by a python script. I guess you can get a pythonmethod to run over your existing documents and produce PDF versions provided you can parse the DTML or some major subset of it. You would also need to add the generated PDF document into the ZODB database and modify the DTML to contain a reference to the generated PDF. ReportLab doesn't use Zope , but I have some experience with it. >To sound out what, if anything, other people are doing in this area: > >I am interested in using ReportLab with Zope, to provide an improved printed >version of >web-published documents.
