添加其他对象并收到错误 MultiValueDictKeyError (Django admin)

我的关系如下：

class Question(models.Model):
   qid = models.PositiveIntegerField(primary_key=True)
   content = models.CharField(max_length=128)

class Answer(models.Model):
   answerid = models.PositiveIntegerField(primary_key=True)
   content = models.CharField(max_length=128)
   question = models.ForeignKey(Question)


class AnswerInline(admin.StackedInline):
   model = Answer
   readonly_fields = ('answerid',)
   extra = 0

class QuestionAdmin(admin.ModelAdmin):    
    inlines = [AnswerInline]
    exclude = ('id')
    list_display = ('content',)

admin.site.register(Question,QuestionAdmin)

假设我有一个问题A，并且我还没有这个问题的答案。所以，当我添加 A 答案时，就可以了。但是，我尝试添加其他答案，系统输出错误 MultiValueDictKeyError：

“在 QueryDict 中找不到键“oam_answer_set-0-answerid”：...

因为 'qid' 和 'answerid' 都不是自动字段。因此，当我保存对象时，django admin 无法将新行插入数据库（缺少主键）。

，我如何自定义 AutoField？

但是，我希望主键的字段类型是 PositiveIntegerField。因此

原文

I have a relationship follow as:

class Question(models.Model):
   qid = models.PositiveIntegerField(primary_key=True)
   content = models.CharField(max_length=128)

class Answer(models.Model):
   answerid = models.PositiveIntegerField(primary_key=True)
   content = models.CharField(max_length=128)
   question = models.ForeignKey(Question)


class AnswerInline(admin.StackedInline):
   model = Answer
   readonly_fields = ('answerid',)
   extra = 0

class QuestionAdmin(admin.ModelAdmin):    
    inlines = [AnswerInline]
    exclude = ('id')
    list_display = ('content',)

admin.site.register(Question,QuestionAdmin)

Suppose I have a question namely A and I haven't any answer for this question yet.
So, when I add an answer of A. It's ok. However, I try to add an other answer, system output an error MultiValueDictKeyError:

"Key 'oam_answer_set-0-answerid' not found in QueryDict:...

Because both of 'qid' and 'answerid' are not an AutoField. So, when I save an object, django admin can not insert a new row into database (missing primary key).

The AutoField is declared an IntegerField. However, I would like the field type of primary key is PositiveIntegerField. For that reason, how can I customize an AutoField?

Thanks

admin ie 中注册 Answer 模型

...
admin.site.register(Answer)

尝试在 admin.py 底部的。您正在使用从 ModelAdmin 继承的内联字段（特别是 readonly_fields），但您可能尚未注册该模型。

Try registering the Answer model with the admin i.e.

...
admin.site.register(Answer)

at the bottom of the admin.py. You are using fields on the inline (specifically readonly_fields) that are inherited from ModelAdmin, but you might not have registered that model.
