Question

我正在为我的应用程序使用django-haystack和Elasticsearch。我已经加载了所有要求并尝试使用search.html

搜索我的索引

但是每当我尝试使用http://localhost:8000/search处的API检索结果时，我都会收到以下错误，而且我已经搜索了很多关于此但却无法获得任何帮助的信息：

RequestError: TransportError(400, u'parsing_exception')

在views.py中搜索查询

def search(uri, term):
    query = json.dumps({
        "query": {
        "bool": {
        "filter": {"term":"channel"}
            }
        }
    })
    response = request.get(uri, data=query)
    results = json.loads(response.text)
    return results

在models.py中记录模型

class Recordings(models.Model):
    channel = models.ForeignKey(Channel, related_name="recordings")
    date = models.DateTimeField(auto_now_add=True)
    duration = models.DurationField(default=0)
    file_size = models.FloatField(default=0.0)
    file_location = models.CharField(max_length=255)
    proceed = models.BooleanField(default=False)

    class Meta:
        get_latest_by = 'date'
        ordering = ['-date']
        index_together = ["date", "channel"]

    def __str__(self):
        return '{channel} {date}'.format(Channel=self.channel, date=self.date)

search_indexes.py

from haystack import indexes
from matches.models import Recordings

class NoteIndex(indexes.SearchIndex, indexes.Indexable):
    text = indexes.CharField(document=True, use_template=True)
    channel = indexes.CharField(model_attr='channel')
    date = indexes.CharField(model_attr='date')
    file_size = indexes.CharField(model_attr='file_size')
    file_location = indexes.CharField(model_attr='file_location')

    def get_model(self):
        return Recordings
