Extending Formulator with a derived product
by Jeff Kowalczyk 03 Jul '02

03 Jul '02

I need to extend formulator functionality with a new property group, akin to 'widget' and 'validator'. Layout is a new class to give fields some positional rendering capabilities. These properties are going to live on the form fields, so the rendering for the form instances can be generic. I've got the basic mechanism working on a copy of the Formulator CVS source. However, I want to switch to deriving my product from Formulator rather than maintaining a private fork of the code. I don't know how to derive from the sophisticated Formulator class heirarchy to accomplish the changes. Can anyone suggest how to set up a derived product to do it? Thanks for any advice. Layout.py is (for now) like Widget.py, except for these changes: [Layout.py (new)] ---------------------------------------------------------------- class Layout: ... property_names = ['vertical_position', 'horizontal_position'] vertical_position = fields.StringField('vertical_position', title='Vertical Position', description=( "vertical position of field in some rendering scheme"), default="", required=0) horizontal_position = fields.StringField('horizontal_positition', title='Horizontal Position', description=( "horizontal position of field in some rendering scheme"), default="", required=0) ... LayoutInstance = Layout() [FieldRegistry.py (added)] ---------------------------------------------------------------- for field in getPropertyFields(field_class.layout): form.add_field(field, "layout") tales_field = fields.TALESField(field.id, title=field.get_value('title'), description="", default="", display_width=40, required=0) tales_form.add_field(tales_field, "layout") method_field = fields.MethodField(field.id, title=field.get_value("title"), description="", default="", required=0) override_form.add_field(method_field, "layout") These modules need to import the new module: [ListAreaTextField.py, MethodField.py, StandardFields.py, TalesField.py (changed)] ---------------------------------------------------------------- import Widget, Validator, Layout [StandardFields.py (changed)] ---------------------------------------------------------------- class StringField(ZMIField): meta_type = "StringField" widget = Widget.TextWidgetInstance validator = Validator.StringValidatorInstance layout = Layout.LayoutInstance (repeated for each field class...) [ListTextAreaField.py (changed)] ---------------------------------------------------------------- class ListTextAreaField(ZMIField): ... widget = ListTextAreaWidgetInstance validator = ListLinesValidatorInstance layout = Layout.LayoutInstance [TalesField.py (changed)] ---------------------------------------------------------------- class TALESField(ZMIField): ... widget = TALESWidgetInstance validator = TALESValidatorInstance layout = Layout.LayoutInstance And a trivial change to allow the new type to coexist with the real one: [Form.py (changed)] ---------------------------------------------------------------- class ZMIForm(ObjectManager, PropertyManager, RoleManager, Item, Form): ... meta_type = "Formulator2 Form"

Current preferred procedure for using Apache and Zope.
by Alec Munro 03 Jul '02

03 Jul '02

Hi all, I'm just trying to get these two to work together for the first time, and I've got the PCGI method working fine, but I'm interested in the Proxy method, as well as maybe FastCGI. I found a tutorial for the first one, but it's over two years old (and Apache complains when I attempt it), so I thought I would ask around here, find out what you guys are doing. Also, it would be interesting to hear peoples reasons for choosing to involve Apache. For me, we currently have a fair amount of static content left over from our old site, and very little development time, so I figured Apache would be better suited to serving that content. Thanks very much. Alec Munro

Get all folder objects in a folder
by Oliver Marx 03 Jul '02

03 Jul '02

Hi I have a little python script: [PYTHON] """ Name list_folders Returns a list of folders. """ folders=container.objectValues('Folder') return folders [/PYTHON] I'm trying to call it from a ZPT [ZPT] <metal:block metal:define-macro="column"> <div tal:define="folders python:here.list_folders()"> <table class="box" summary="Test" cellpadding="0" cellspacing="0"> <thead> <tr><th>Navigation</th><th class="empty"> </th></tr> </thead> <tbody> <tr valign="top" tal:repeat="folder folders"> <td><a href="./Partners" tal:attributes="href folder/absolute_url" tal:content="folder/getId">Partners</a></td> </tr> </tbody> </table> </div> </metal:block> [/ZPT] But it doesn't work. Zope complains about the call python:here.list_folders(). What are my eyes missing or what do my brain not understand? Thanks for your time :) \Oliver --- Outgoing mail is certified Virus Free.

Hi, Currently, to get things working, I display all results on one screen. I know the users want to see the first 10 results and click for the next 10 and so on. Can anyone point me in the right direction to read about this feature or sites that I can look at the code. Thanks. Larry McDonnell Proton Energy Systems 50 Inwood Rd.

ObjectManager and product instantiation
by Sylvain Thénault 03 Jul '02

03 Jul '02

hello, I wish to know if there is another way than self.manage_addProduct['OFSP'].manage_addNiceProduct(id) to add a product to an object which inherits from ObjectManager ? My problem is that I would like to create the object first and add it latter to the object manager. Idea ? TIA -- Sylvain Thénault

Problem with Zope 2.5.1, Linux, Permissions of DTML variables
by Daniel Paul 03 Jul '02

03 Jul '02

Hello, I have the following problem: If I try to access an particular Object (Folder) in Zope with a login I created and verified personally only minutes ago, I get the following error:  If I do this with an other login which is defined at a higher level of our Zope tree, everything works fine. I had a similar problem with a property which was defined at a higher level (directory) so that some users had no access to it. But the dtml-var title_or_id is no property I think. Right? I hope to find a solution to this soon. Thank you in advance, Daniel Paul bitubi.de GmbH (e-Mail: dpaul_NOSPAM_(a)gmx.net)
