的Django無法檢測模型的現場

這裏是否存在等是我的模型：的Django無法檢測模型的現場

class Question(models.Model): 
    id = models.AutoField(primary_key=True) 
    question_title = models.CharField(max_length=100, default="no title") 
    question_text = models.CharField(max_length=200, default ="no content") 

    def __unicode__(self): 
     return self.question_title + self.question_text

，並在我的管理配置頁面，設置我的QuestionAdmin類是這樣的：

class QuestionAdmin(admin.ModelAdmin): 
    fieldsets = [ 
     ('Question ID', {'fields':['id_pk']}), 
     ('Question content',{'fields':['question_title',"question_text"]}) 
    ]

，然後我應用這個配置到Django的管理頁面：

admin.site.register(Question, QuestionAdmin)

，這裏是我的全部錯誤跟蹤：

我已經下使用manage.py makemigrations和遷移命令，這樣在我的數據庫表polls_question，應該在shcema主鍵名爲id我的後端SQLite數據庫更新。

你註冊了admin.site.register（QuestionAdmin）這樣的管理字段嗎？遷移沒有錯誤？ – hansTheFranz

@hansTheFraz我相信它的admin.site.register（Question，QuestionAdmin）？和遷移不會給我任何錯誤 – paradox

@paradox爲什麼你想改變'問題'的ID？我相信這是你的問題。你不能只改變一個對象的ID。 –

問題是id字段無法更改，必須呈現爲只讀字段。這裏是如何做到這一點的例子：

class QuestionAdmin(admin.ModelAdmin): 
    fieldsets = [ 
     ('Question ID', {'fields':['id']}), 
     ('Question content',{'fields':['question_title',"question_text"]}) 
    ] 
    readonly_fields = ('id',)

你必須在ModelAdmin類，它必須是一個列表或元組的readonly_fields屬性來定義它。
