Wrestling with the ZopeBook (ScriptingZope.stx), I'm trying to call a script from a DTML document to return eq the title for the document (as learning curve).

The document has: <form action="myScript" method="POST> <input type="submit"> </form>

The 'myScript' has: Return context.title

The result is the title for the folder where the document is in. I'm expecting the title for the document itself.

Context always seems to be the folder I'm working on. How do I get the object (document)?

myScript is not called from within your dtml-method. In your example myScript is just a relative URL that triggers the execution of the script when the user presses the submit button. If I understand you (and zope) correctly, what you're trying to do is to discover from where myScript is called, and this has nothing to do with acquisition. You can find its URL looking at the REQUEST.HTTP_REFERER or easier, create a hidden input in your form: <form action="myScript" method="POST> <input type="hidden" name="caller_title" value="&dtml-title;"> <input type="submit"> </form> and add a caller_title parameter to myScript. Maybe zope provides some nice way to determine the object which has triggered the execution of myScript, I don't know ... REQUEST.HTTP_REFERER and some traversal method can take you to the object.

By name, as in: context.myDocument The script is *not in* the document, it's in the same folder. DTML documents/methods are not container objects. I think you're confusing calling with containment (admittedly, DTML probably encourages this). If you want to pass objects to the script, you can also simply call it with arguments: <dtml-var expr="myScript(title)"> will pass it the document's title, for example. This is probably much better style, generally. Of course, just to really confuse yourself, you could pass the whole namespace: <dtml-var expr="myScript(_)"> Then your first argument will be a mapping containing all the names known to the document.

You've got two problems. The first is that some objects acquire certain attributes from their container. A DTML Method will always return the names defined by its container before exposing its own names. The more fundamental problem, though, is that you aren't calling your form object when you think you are. Say you have two objects: my_form (DTML Document) my_target (Python Script) When a client makes a request for my_form, they are *calling* the my_form object. Since this object returns HTML when called, they get a nice-looking web form that includes a tag like: <form method=post action=my_target>

From this point on, you are **not** calling my_form any more. Any calculations that must be done by the my_form object must already be done by this point.

Submitting this form calls my_target. Any calculations performed by my_target will be done in the context of how my_target is set up and what request you call it with. The my_form object has no direct relevance at this point. If you need for my_target to know the title property of the my_form object that created the form, you'll want to include something like this in my_form: <input type=hidden value=<dtml-var title>> This way, you're evaluating title in the context of the correct object and passing that value along to the object you actually want to do something with it. Of course, DTML Methods don't have their own namespcaes so that won't work in your case. You can work around it (or cut & paste your code into a DTML Document object), but it may be just as easy to hand code it. HTH, Dylan
