python - AttributeError at/api/project/'Query' 对象没有属性 'query_terms' tastypie

Question

class Project(models.Model):
     project_name = models.CharField(max_length=100,default=None)
     user = models.ForeignKey(User, on_delete=models.CASCADE)
     intro = models.TextField(default=None)
     start_date = models.DateField()
     end_date = models.DateField()

    def __str__(self):
       return self.project_name



class UserResource(ModelResource):
     class Meta:


class ProjectResource(ModelResource):
     user = fields.ToManyField(UserResource, 'user',  full=True)

    class Meta:
       queryset = Project.objects.all()
       resource_name = 'project'
       allowed_methods = ['post', 'get']
       authorization = DjangoAuthorization()

tastypie 的新手，当我关注文档时，我在 api url (api/project/) 上遇到属性错误不知道 query_terms 的含义，尝试搜索，提前致谢

AttributeError: 'Query' object has no attribute 'query_terms'

似乎当前版本的 Django 和 Tastypie 不能很好地结合在一起。 该修复程序隐藏在 Nelly Ngo 提供的链接中，更具体地说是 here .

一个临时的 hackish 修复是修补 tastypie/resources.py。 在我的系统上的/usr/local/lib/python3.5/dist-packages/tastypie。

替换行:

if getattr(self._meta, 'queryset', None) is not None:
    # Get the possible query terms from the current QuerySet.
    query_terms = self._meta.queryset.query.query_terms
else:
    query_terms = QUERY_TERMS

与:

query_terms = QUERY_TERMS

和

query_terms = query_terms | set(GeometryField.class_lookups.keys())

与:

query_terms |= set(GeometryField.class_lookups.keys())
