Hi All,
Can someone please tell me if there is a way to render macros for a
browser view template, i.e an instance of SimpleViewClass?
I tried to use macroContent in plone/app/kss/plonekssview.py but ran
into some problems.
I'm using plone.app.kss-1.4.3-py2.4.egg
The error I get is:
> Module plone.app.kss.plonekssview, line 35, in macroContent
> RuntimeError: Macro not found
Upon closer inspection through a pdb trace:
> (Pdb) l
> 24 jointpath = '/'.join(path[:-2]).encode('ascii')
> 25 macroobj = self.context.restrictedTraverse(jointpath)
> 26 import pdb; pdb.set_trace()
> 27 -> the_macro = macroobj.macros[path[-1]]
> (Pdb) p macroobj
> <Products.Five.metaclass.SimpleViewClass from
> /home/jc/work/ClassicFM/buildout/trunk/parts/development-products/ClassicFMSite/browser/templates/podcast-detail.pt
> object at 0xe49a98c>
> (Pdb) p macroobj.macros
> *** AttributeError: <exceptions.AttributeError instance at 0xd8d53cc>]
So the SimpleViewClass instance does not have a macros attributes, but
after some investigation I saw that I could access the macros through
the index attribute as follows:
> (Pdb) macroobj.index.macros.keys()
> ['podcast_item']
So, in trying to understand what macroobj.index is, I do the following:
> (Pdb) p macroobj.index
> <ImplicitAcquirerWrapper object at 0xdea502c>
> (Pdb) p macroobj.index.aq_inner
> <ImplicitAcquirerWrapper object at 0xdea62cc>
Which didn't really explain it to me.
Since realising this, I've modified macroContent as follows:
> try:
> the_macro = macroobj.macros[path[-1]]
> except AttributeError:
> # XXX: My customization, the only way I could get macros
> # of browser templates to render. - JC Brand
> the_macro = macroobj.index.macros[path[-1]]
> except IndexError:
> raise RuntimeError, 'Macro not found'
and macroContent now renders macros in my browser view templates.
But at the moment, I still don't really understand what the index
attribute points to... it looks to me like a template object of the type
you get with skins templates, but I'm not sure.
Also, I don't know if there is a better and more elegant way of doing
this, without having to hack macroContent.
Any comments and help welcome.
Thanks a lot
JC
