METAL question
by Andreas Tille 26 Sep '03

26 Sep '03

Hi, I try to use Formulator a little bit more effective to enhance the my code with metal. Currently I do the following: <th> <span tal:replace="structure python:form.item_a.get_value('title')">item_a</span> </th> <td tal:define="item_a request/item_a|nothing"> <input tal:replace="structure python:form.item_a.render(item_a)"> </td> <th> <span tal:replace="structure python:form.item_b.get_value('title')">item_b</span> </th> <td tal:define="item_b request/item_b|nothing"> <input tal:replace="structure python:form.item_b.render(item_b)"> </td> ... I would like to find a clever METAL macro which enables me to use <div metal:use-macro="here/form_zpt/macros/item_macro/item_a">Item A</div> <div metal:use-macro="here/form_zpt/macros/item_macro/item_b">Item B</div> ... Unfortunately I have no idea this is possible at all because I have to handle different objects with just the same naming convention: form.item_a item_a (Variable to define) request/item_a Any hint whether my intent makes sense or if this is a stupid idea? Kind regards Andreas.

I've found that intelligent >googling of the list archives has been at least as helpful, if not more so >for me than the documentation overall. Even trying to grok some simple concepts. e.g. one can specify parameters on a Script (Python) object, but nothing I can find explains how these parameters get values. In looking thru the Shopping Cart Example I found a form specifying in part <form action="addItems"> <input type="text" name="orders.quantity:records" ... where addItems is a script in the same container, and addItems specifies orders, REQUEST=None as parameters. What's missing for me is the relationship between the form and the parameter list. In another example I experimented with a Page Template calculateForm: ... <form action="calculateSum"> <input type="text" name="a" tal:attributes="value request/a"><br> <input type="text" name="b" tal:attributes="value request/b"><br> <input type="text" tal:attributes="value result"><br> <input type=submit value="Submit" name="Next10"> </form> ... where calculateSum is script: ## parameters a,b sum=int(a)+int(b) return container.calculateForm(result=sum) After clicking Submit the form reappears, with the values for a and b filled in. What is the magic that associates the values I entered for a and b with the request to display the form again?

[Ann] Post-Authentication-Hook patch
by Dieter Maurer 26 Sep '03

26 Sep '03

In some case, you want to take special actions once the user has been determined at the end of traversal. You may, e.g., want to deny Manager role to any non HTTPS request. This patch adds support for a *post authentication hook*. It adds code to the 'validated_hook', called when the user is successfully authenticated. The code tries to acquire an object 'post_authentication_hook' from 'request.PARENTS[0]'. If this is successful, it calls this object with the arguments 'request' and 'user'. Usually, this call will raise Unauthorized when it has objections against the request. Download: <http://www.dieter.handshake.de/pyprojects/zope/postauth.pat> Dieter

Zope 2.7 Beta Installer
by Andy McKay 26 Sep '03

26 Sep '03

Hi, I've revived the Zope installer scripts so that a new Zope 2.7 installer is being built that compliments the one Zope Corp. builds. This installer is currently in beta but will hopefully be ready when 2.7 is launched. It can be downloaded here: http://www.clearwind.ca/zope It features all the same goodies as the Zope Corp. plus: * Additional Python modules: o Full Win 32 Installation o PIL o Reportlab * Additional Documentation: o Zope Book (2.6 edition) o Dive into Python o Python 2.2 documentation * Additional modules and products: o External Editor o LocalFS o ZSyncer o Formulator o Localizer o Translation Service Plus its not dependent upon Zope Corp to build, it's built straight from a CVS check out each night. Anyway the installer is in beta, so any testing and bug reports would be appreciated (and it will soon be moved to a fast server). In particular if there are any products that you would like shipped with it, please let me know. -- Andy McKay ClearWind Consulting http://www.clearwind.ca

dtml <-> ZPT
by Stephan Goeldi 26 Sep '03

26 Sep '03

I'd like to use the ShoppingCart from the Examples folder in Zope 2.5.1 and modify it. In the script getItem are the products, descriptions and prices. The price part looks like this: 'price' : 22.0} I'd like to replace it by something, which looks like this in DTML: <dtml-let a="price/currency"> <dtml-var a fmt="%.0f"> </dtml-let> I am a total newbie to ZPT and Python, so how can I achieve the above DTML in a Python script? the price/currency structure is needed, because the price is available as a property and the structure enables the user to select another currency. TIA for any help. Stephan

How does it end up in self? > I am writing a product and borrowed this technique from the JTracker product http://zope.org/Members/jens/Folder.2003-08-11.1400/JTracker. Basically I have a file "Template_Site.pt" which defines a macro. Another file "Template_index_html.pt" that uses that macro. I then define these attributes within the class: Template_Site=PageTemplateFile('Template_Site.pt', _wwwdir) Template_index_html=PageTemplateFile('Template_index_html.pt', _wwwdir) Within Template_index_html.pt the following is defined: <div id="content_main" metal:fill-slot="content_main"> <span tal:replace="structure here/Content_Main|nothing"> Main Content </span> </div> The python method within the class then redifines the attribute Content_Main to define which file I want to pull my html from for the main body of the page. Am I abusing my zpt? > as a concept is very simple (hence why everyone loves it), the implementation is > often very complex... think about form submission, and one-way state transitions...

sql returning number
by Derek S. Wilson 26 Sep '03

26 Sep '03

I have a slight problem... I'm working on a project management zope site, and I need to create a new sequential project ID for each project. I made a zsql statement as follows... select MAX(ID)+1 from AllProjects This gives the expected: (Maximum(ALLPROJECTS.ID))+() 3 I now want to take that value(3) and use it as my ID. The column name is ID, So, here's how I go about doing it. <dtml-in getNewProjectID> Here's the ID: <dtml-var ID> </dtml-in> but it keeps giving me a 'KeyError" - "ID" of course, lowercase id just shows the name of the folder that the dtml document is in. So, does anyone know how I can put that result into my webpage? Thanks, Derek S.

I've got an account with them, and I've been absolutely thrilled. Very good range of services, excellent price, and fast, attentive support. I wish my university's IT department were as well run.
