AFAICT, this should work so long as the DTMLFile is being called in the context of an instance of the class that defines the name referenced from the dtml-var. Please provide the error message and traceback. That may lend some clues. -Casey On Thursday 25 April 2002 08:41 am, Terry Hancock allegedly wrote:
I'm converting a through-the-web prototype to a product.
Following the conventions of the examples I've seen and the ZDG (and previous tutorials on products), I'm using DTML "manage_add..." forms. However, I have a number of these with shared information, so it would be much more convenient to factor out the common content into a separate DTML file, which I've done.
To be more specific, I have an add-form for my "GalleryArt" object, called addGalleryArt, which includes a file add_contrib_dtml which has a common portion of the add form used by several objects in the product.
However, I can't figure out how to include the component DTML in the DTML form.
I'm using DTMLFile() to get the original DTML, which is then registered in my __init__.py. I've used the same DTMLFile() method to capture the shared component. So I now have a reference to add_contrib_dtml in the Python module which defines GalleryArt.
Now, in order to get this into the namespace for the DTML form, I tried defining it like this:
add_contrib_dtml = DTMLFile('dtml/add_contrib', globals())
manage_addGalleryArt = DTMLFile('dtml/addGalleryArt', globals(), add_contrib_dtml=add_contrib_dtml)
(there's a line like <dtml-var add_contrib_dtml> in the dtml/addGalleryArt.dtml file).
However, when I call this form in Zope by trying to add the GalleryArt object, I get an AttribError exception thrown from add_contrib which says it can't find "_aq_parent".
This presumeably stands for "acquisition parent" and is certainly not referred to explicitly by me -- so it has to be something that DTML expects Zope to provide it with. So presumeably it did find add_contrib_dtml, but it isn't happy with its namespace.
This must be because the DTML files are not in the Zope hierarchy, but are instead in my Product, but I then don't understand why the DTML forms worked in the first place. SO -- the question I'm asking is how was I _supposed_ to do this? (How) can I build a DTML hierarchy like this inside my Product?
Thanks for any ideas!
