django-sphinx BuildExcerpts

Question

I'm trying to use BuildExcerpts in django sphinx. My view looks something like this:

q = request.GET.get('q', '')

my_model_list = MyModel.search.query(q).set_options(passages=True, passages_opts={
                        'before_match':"<font color='red'>",
                        'after_match':'</font>',
                        'chunk_separator':' ... ',
                        'around':6,
                         })

When I run this I get an AssertionError

Here's the trace:

Traceback:

Exception Type: AssertionError at /

I'm not really sure what's going on. Anyone have an experience with this?

I'm using django 1.2.3, Sphinx 0.9.9, and django-sphinx 2.2.3.

For others who are having similar problems, here is what I had to do to fix it.

Go to your django-sphinx install folder and open up models.py. On line 650, you need to replace these two lines:

docs = [getattr(instance, f) for f in fields]
if isinstance(self._passages_opts, dict):

with

 docs = [getattr(instance, f) for f in fields]

 for index, doc in enumerate(docs):
     if (not (isinstance(doc, str)) and (not isinstance(doc, unicode))):
                         docs[index] = repr(doc)

  if isinstance(self._passages_opts, dict):

Then you can access your excerpts like this in your view:

for r in results_set:
   print r.sphinx.get('passages') 

or in the template like this:

{{record.sphinx.passages.content|safe}}
