Question

我目前有一堆旧评论，我需要迁移到django.contrib.comment，计划是手动创建Comment实例，然后按如下方式保存：

# assume some_content is NOT a django Comment instance, but in some proprietary format
# assume the model I'm attaching the comment to is called Blog i.e models.Blog
c = Comment()
c.user = user
c.submit_date = some_comment.comment_date_time
c.comment = some_comment.comment
... 
c.save()

主要问题是BaseCommentAbstractModel中找到的课程django.contrib.comment.model中缺少的信息。特别是三个领域：

BaseCommentAbstractModel(models.Model):
    # Content-object field
    content_type   = models.ForeignKey(ContentType,
        verbose_name=_('content type'),
        related_name="content_type_set_for_%(class)s")
    object_pk      = models.TextField(_('object ID'))
    content_object = generic.GenericForeignKey(ct_field="content_type", fk_field="object_pk")

我阅读了文档，并尽我所能来源，但它不够详细。如何从模型对象（model.Blog）中正确指定这些字段？

也许有一个方法可以接受模型对象和要添加的注释的内容？

来自documentation：




set the content_type to an instance of ContentType of your model (the one you're attaching the comment to):

content_type = ContentType.objects.get_for_model(Blog)
set object_pk to the primary key of your object:

object_pk = myBlog_instance.pk
content_object will point to these 2 fields, you dont have to set it.

content_type = ContentType.objects.get_for_model(Blog)

在Django中创建“Comment”实例进行迁移？
