Question

我想在django sphinx中使用BuildExcerpts。我的觀點看起來是這樣的：

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, 
         }) 

當我運行此我得到一個AssertionError

這裏的痕跡：

Traceback:

    100.      response = callback(request, *callback_args, **callback_kwargs)

    791.   assert(isinstance(doc, str)) 

Exception Type: AssertionError at/
Exception Value: 

我真的不知道發生了什麼事情。任何人都有這方面的經驗？

我使用的是django 1.2.3，Sphinx 0.9.9和django-sphinx 2.2.3。

對於其他有類似問題的人來說，這是我必須要解決的問題。

轉到您的django-sphinx安裝文件夾並打開models.py。上線650，則需要更換這兩行：

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

與

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): 

然後你就可以訪問您的摘錄還有你的觀點：

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

或模板像這樣：

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