django-sphinx 构建摘录

Question

我正在尝试在 django sphinx 中使用 BuildExcerpts。我的视图看起来像这样：

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,
                         })

当我运行这个时，我得到一个 AssertionError

这是跟踪：

Traceback:

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

  791.          assert(isinstance(doc, str))

Exception Type: AssertionError at /
Exception Value: 

我不太确定发生了什么。有人有这方面的经验吗？

我正在使用 django 1.2.3、Sphinx 0.9.9 和 django-sphinx 2.2.3。

Answer 1

对于遇到类似问题的其他人，这是我必须做的来解决它。

转到 django-sphinx 安装文件夹并打开 models.py。在第 650 行，您需要将这两行：替换

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

为

 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):

然后您可以在视图中像这样访问您的摘录：

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

或在模板中像这样：

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