Question

我有这些模特：

class Video(models.Model):
     suggestion = models.ForeignKey("VideoSuggestion", null=True)
     title = models.CharField(max_length=300)
     description = models.TextField(blank=True, null=True)

     def __unicode__(self):
          return u'%s %s' % (self.title, self.description)

class VideoSuggestion(models.Model):
     sugestion_literal = models.CharField(max_length=100, unique=True)

     def __unicode__(self):
         return self.sugestion_literal

class VideoVariation(models.Model):
      video = models.ForeignKey(Video, related_name='variations')

      def __unicode__(self):
          return u"Variations"

admin.py

class VideoVariationInline(admin.TabularInline):
      model = VideoVariation

class VideoAdmin(admin.ModelAdmin):
      inlines = [
          VideoVariationInline,
      ]

有时，有时候，我收到错误

ValidationError([u'ManagementForm data is missing or has been tampered with'])

当我想保存新对象并保存现有对象时

我注意到的是，在这些情况下缺少内联表单（VideoVariationInline）。

我已经读过这可能是由__unicode__方法引起的，但我认为它们都是正确的，对吧？我究竟做错了什么？

django admin - 有时内联缺失
