The feature was added hastily and is infrequently used. Probably would have set "request.wrapped_body" to "response.unicode_body" instead of "response.body" if I had been thinking about it hard enough. But you can get the same effect by doing "request.wrapped_response.unicode_body". - C ___ Repoze-dev mailing list Repoze-dev@lists.repoze.org http://lists.repoze.org/listinfo/repoze-dev
Re: [Repoze-dev] bfg chameleon unicode crash with wrapper views
Oops I copied a traceback from one of my attempts at fixing it.
Tres, that worked, thanks. I'm curious why it's necessary though. It seems
to me it should "just work" right? Can anyone explain further why that step
is necessary once a view is wrapped? ( related note, wrapper views are
awesome, the docs could totally use more wrapper view examples! =)
Malte, how do I do that? Is it possible to do that when I am using a
renderer argument to a view zcml registration? I am having problems when I
get unicode out of the db too but haven't figured out whether it's a
chameleon setting I'm missing or a mysql encoding setting that's off.
thanks guys

Re: [Repoze-dev] bfg chameleon unicode crash with wrapper views
Alternatively, enable implicit decoding using
``default_encoding="utf-8"`` (in the template constructor). This is
enabled on Plone, for instance.

The code in the traceback doesn't match the sample you showed above:
the 'wrapped_body' is an encoded string (WebOb responses always encode
the body with the supplied charset) which the view is trying to decode
(back?) to unicode without supplying the encoding. The default encoding
used by WebOb is 'UTF-8', so I would try:
def __call__(self):
tmpl_dict = {}
body = self.request.wrapped_body
tmpl_dict['inner_content'] = body.decode('UTF-8')
return tmpl_dict

[Repoze-dev] bfg chameleon unicode crash with wrapper views
Not sure where I'm supposed to ask this now, here? Pyramid list?
I have view with a chameleon template that contains utf-8 unicode special
chars. It renders fine when rendered on it's own from a view. As soon as I
wrap that view with a wrapper view, I get errors with the wrapper choking on
the unicode.
My master views call method is like this:
def __call__(self):
tmpl_dict = {}
tmpl_dict['inner_content'] = self.request.wrapped_body
return tmpl_dict
I get the following traceback ( snipped ):
File
"/home/jordans/Jordans/eggs/repoze.bfg-1.2.2-py2.6.egg/repoze/bfg/router.py",
line 130, in __call__
response = view_callable(context, request)
File
"/home/jordans/Jordans/eggs/repoze.bfg-1.2.2-py2.6.egg/repoze/bfg/configuration.py",
line 1724, in _owrapped_view
wrapper_viewname)
File
"/home/jordans/Jordans/eggs/repoze.bfg-1.2.2-py2.6.egg/repoze/bfg/view.py",
line 90, in render_view_to_response
return view(context, request)
File
"/home/jordans/Jordans/eggs/repoze.bfg-1.2.2-py2.6.egg/repoze/bfg/configuration.py",
line 1663, in _bfg_class_view
response = inst()
File "/home/jordans/Jordans/jordans/views/master_view.py", line 22, in
__call__
tmpl_dict['inner_content'] = u"%s" % self.request.wrapped_body
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 4090:
ordinal not in range(128)
Any clues?
thanks
