    class MusicInfo(models.Model): music_id = models.CharField(primary_key=True, default=hash_func) music_name = # 略... 

    比如上面的 Model,music_id 是随机生成的哈希,在后台管理中会显示 music_id,我想在表单中隐藏这个字段,最好连 input hidden 标签也没有。

    比如在新增的时候隐藏这行 音乐ID:

    解决了……

    forms.py 创建一个 MusicInfoForm,其 Meta class 的成员 exclude 元组含 music_id,将 MusicInfoForm 关联到 admin.py 的 MusicInfoAdmin 的 form 成员。

    这样,新增资源的时候,ID不可更改,但是浏览资源信息的时候可以看到ID,编辑资源也不可更改ID。

    为什么要手动设置一个 id 呢,用自增的不好么

    把该 Field 的 editable 设为 False 不就可以了吗?

    https://docs.djangoproject.com/en/1.10/ref/models/fields/#editable

    Field.editable

    If False, the field will not be displayed in the admin or any other ModelForm. They are also skipped during model validation. Default is True.

    1 、在 admin fields 中去掉 music_id
    2 、在 admin list_display 加上 music_id
    3 、重写 save 函数,在保存的时候如果 music_id 为空,则自动生成一个
