Question

我正在尝试使用haystack-whoosh创建多个查询我在命令提示符下面收到错误：

   C:\Users\varun\Desktop\Project\mysite>python manage.py rebuild_index

settings.py

     'autocomplete': {
        'ENGINE': 'haystack.backends.whoosh_backend.WhooshEngine',

而我的search_indexes.py读取

import datetime
from haystack import indexes
from Post.models import Post

class PostIndex(indexes.SearchIndex,indexes.Indexable):
    from1 = models.CharField(document=True,use_template=True)
    type_of_truck = models.CharField(max_length=20)
    date = models.DateField()
    slug = models.SlugField(unique=True)
    weight = models.DecimalField( max_digits=5, decimal_places=2)
    Material_Name = models.CharField(max_length=20)
    To = models.CharField(max_length=20)
    Number_Of_Truck = models.CharField(max_length=20)
    Time = models.TimeField()
    Volume = models.CharField(max_length=20)
    Material_Type = models.CharField(max_length=20)

    content_auto = indexes.EdgeNgramField(model_attr='from1')

    def get_model(self):
        return Post
    def index_queryset(self,using=None):
            """used when entire index for model is updated."""
        return self.get.model().objects.all()

models.py

class Post(models.Model):

    id = models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')
    user = models.ForeignKey(settings.AUTH_USER_MODEL, default=1)
    from1 = models.CharField(max_length=20)
    type_of_truck = models.CharField(max_length=20)
    date = models.DateField()
    slug = models.SlugField(unique=True)
    weight = models.DecimalField( max_digits=5, decimal_places=2)
    Material_Name = models.CharField(max_length=20)
    To = models.CharField(max_length=20)
    Number_Of_Truck = models.CharField(max_length=20)
    Time = models.TimeField()
    Volume = models.CharField(max_length=20)
    Material_Type = models.CharField(max_length=20)
    #updated = models.DateTimeField(auto_now=True, auto_now_add=False)
    timestamp = models.DateTimeField(auto_now=False, auto_now_add=True)

POST_TEXT

{{object.from1}}
{{object.To}}
{{object.Material_Type}}

虽然我刚刚在views.py中添加了“from haystack.query import SearchQuerySet” 因为早先我的搜索查询工作但我一次只能搜索单个查询，而我想创建具有多个过滤器的查询

请帮助我收到错误的原因

django haystack嗖嗖地搜索
