Question

我正在尝试使用haystack创建多个查询 - 我的最后一个问题是通过放置双反斜杠解决但现在出现了新的错误。我在命令提示符下面收到错误：

而我的search_indexes.py读取

    import datetime
from haystack import indexes
from .models import Post
from django.contrib.auth import authenticate, get_user_model

class PostIndex(indexes.SearchIndex,indexes.Indexable):
    text = indexes.CharField(document=True,use_template=True)
    type_of_truck = indexes.CharField(model_attr='type_of_truck')
    date = indexes.DateField(model_attr='date')
    #slug = indexes.SlugField(unique=True)
    weight = indexes.DecimalField(model_attr='weight')
    Material_Name = indexes.CharField(model_attr='Material_Name')
    To = indexes.CharField(model_attr='To')
    Number_Of_Truck = indexes.CharField(model_attr='Number_Of_Truck')
    #Time = indexes.TimeField()
    Volume = indexes.CharField(model_attr='Volume')
    Material_Type = indexes.CharField(model_attr='Material_Type')

    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}}

虽然我刚刚从haystack.query中添加＆＃34;导入SearchQuerySet＆＃34;在我的views.py中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

Answer 1

每个搜索索引必须在所有搜索索引中都包含document=True字段，并且名称相同，例如：

class FirstIndex(ndexes.SearchIndex,indexes.Indexable):
    text = indexes.EdgeNgramField(document=True)

class SecondIndex(ndexes.SearchIndex,indexes.Indexable):
    text = indexes.EdgeNgramField(document=True)

接下来就是你不能使用model.CharField作为索引字段！你需要使用：

indexes.<field_type>

所有＆＃39; SearchIndex＆＃39;课程必须使用相同的文字＆＃39; ＆＃39; document = True＆＃39;的字段名称领域。违规索引是＆＃39; <personal.search_indexes.postindex
