我正在设计一个简单的MCQ应用程序，使用django网站django版本1.6.1中的ManyToOne关系。我有一个内联管理员表单，它可以让我添加/编辑来自同一个变更表单的给定问题的答案。但是，如果在使用其答案保存问题后，我无法编辑/添加来自同一表单的答案并获取MultiValueDictKeyError。我的模型是：MultiValueDictKeyError当编辑内联管理对象
class SBA (models.Model):
question = models.TextField(blank=False)
system = models.CharField(max_length=3, choices=pacscon.System.which_system)
case = models.ForeignKey('pacscon.Patient')
created = models.DateField(auto_now_add=True)
reference = models.TextField(blank=True)
def __unicode__(self):
return self.question
class Answer(models.Model):
id = models.AutoField(primary_key=True)
body = models.TextField()
correct = models.BooleanField(default=False)
sba = models.ForeignKey(SBA, null=True)
def __unicode__(self):
return self.body
的admin.py如下：
from models import Answer, SBA, Mnemonic
#from django import forms
from django.contrib import admin
class AnswerInline(admin.StackedInline):
model = Answer
extra = 2
class SBAAdmin(admin.ModelAdmin):
fieldsets = (
(None, {
'fields': ('question', 'system', 'case', 'reference')
}),
)
inlines = [
AnswerInline,
]
readonly_fields = ('created',)
admin.site.register(SBA, SBAAdmin)
admin.site.register(Answer)
admin.site.register(Mnemonic)
和错误消息是：

我已经搜索在谷歌类似的请求，计算器，我的django包完全保持最新状态（包括其他答案中建议的管理内联模板）。将感谢任何帮助。谢谢
P.S这几乎可以肯定是一个错误，因为我可以在使用类似的ManyToOne关系模型的官方django“投票”教程中复制问题。
任何想法是什么导致它，因为我看到同样的错误，但我没有使用Grappeli。我有一种感觉，这是与基于类的视图/混合。 –
