剛剛在Whoosh + Haystack上開始。乾草堆+飛快移動的根：錯誤更新<appname>使用默認
我測試了一個測試模型，其索引良好，並給出了結果。但是索引對於第二模型的一些未知的原因（重要的）
這裏失敗是模型
class Sale(models.Model):
brand = models.ForeignKey('Brand', related_name='sales_p')
outlets = models.ManyToManyField('Outlet', null=True, blank=True, related_name='sales')
child_brands = models.ManyToManyField('Brand', null=True, blank=True, related_name='sales_c')
child_categories = models.ManyToManyField('Category', null=True, blank=True, related_name='sales_c')
#collecting subcategories for subcategory sale
child_subcategories = models.ManyToManyField('SubCategory', null=True, blank=True,related_name='subcategory')
該搜索索引是
class SaleIndex(indexes.SearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
outlets = indexes.CharField(model_attr='outlets')
child_brands = indexes.CharField(model_attr = 'child_brands')
child_categories = indexes.CharField(model_attr = 'child_categories')
child_subcategories = indexes.CharField(model_attr = 'child_subcategories')
content_auto = indexes.CharField(model_attr='brand')
def get_model(self):
return Sale
def index_queryset(self, using=None):
return Sale.objects.all()
def prep_childbrands(self, object):
return [brand.name for brand in self.child_brands.all()]
沒有其他人在世界似乎曾經面對過這個問題。一般來說對編程來說是新的。有什麼我失蹤，這是顯而易見的？
回溯是否有幫助：

引用了很多擺弄我可以說，誤差僅爲拋出後字段條目。如果我只嘗試索引foreignkey字段（上面命名的品牌），那麼索引似乎正確進行。 – Kunstructor
