我有这样的模型:
class Photo(ImageModel):
title = models.CharField(_('Title'), max_length=100, unique=True)
title_slug = models.SlugField(_('slug'), unique=True)
name = models.CharField(max_length=50, verbose_name="Name", blank=True)
class GroupUpload(ImageModel):
title = models.CharField(verbose_name="Group Name", max_length=75)
date_added = models.DateTimeField(verbose_name="Date Added",
default=datetime.now, editable=False)
caption = models.TextField(verbose_name="Caption", blank=True)
photos = models.ManyToManyField('Photo', related_name='+',
verbose_name=_('F'),null=True, blank=True, through='GroupuploadPhotos')
我的搜索索引:
class PostIndex(indexes.RealTimeSearchIndex, indexes.Indexable):
text = indexes.CharField(document=True, use_template=True)
date_added = indexes.DateTimeField(model_attr='date_added')
def get_model(self):
return Photo
def index_queryset(self):
return self.get_model().objects.filter(date_added__lte=
datetime.datetime.now())
现在我想获取与照片相关的 GroupUpload 对象。有了这个定义，我在 GroupUpload 中只得到照片对象而不是相关对象。我检查了文档。但还没有解决。
最佳答案
如果您将 related_name='+' 放入您的 class GroupUpload 中，会发生什么？
更新:
Why not set related_name='group_uploads' and use photo.group_uploads.all() (or if it as haystack SearchResult - result.object.group_uploads.all())?
