如何在django-admin中隐藏一些字段？

Question

class Book(models.Model):
    title = models.CharField(..., null=True)
    type = models.CharField(...)
    author = models.CharField(...)

我在models.py中有一个简单的类.在管理员中,我希望在保存的书的类型为1时隐藏书的标题(在书的详细信息表格中).如何以最简单的方式进行？

Answer 1

对于Django> 1.8,可以直接设置要在admin中排除的字段:

 class PostCodesAdmin(admin.ModelAdmin):
      exclude = ('pcname',)

通过设置Field属性,可以在Django的ORM中直接定义隐藏字段: editable = False

例如

class PostCodes(models.Model):
  gisid  = models.IntegerField(primary_key=True)
  pcname = models.CharField(max_length=32, db_index=True, editable=False)
  ...

但是,直接设置或更改模型的字段可能并不总是可行或有利的.原则上,以下admin.py设置可以工作,但不会因为排除是InlineModelAdmin选项.

class PostCodesAdmin(admin.ModelAdmin):
     exclude = ('pcname',)
....

至少在Django 1.4(以及可能的更新版本号)中工作的解决方案是:

class PostCodesAdmin(admin.ModelAdmin):
  def get_form(self, request, obj=None, **kwargs):
      form = super(PostCodesAdmin, self).get_form(request, obj, **kwargs)
      del form.base_fields['enable_comments'] 
      return form

对于项目的管理列表视图,只需省略不需要的字段即可:例如

class PostCodesAdmin(admin.ModelAdmin):
  list_display = ('id', 'gisid', 'title', )

你要在你的模块中创建admin.py(可能是书)

class BookAdmin(admin.ModelAdmin):
    list_display = ("pk", "get_title_or_nothing")

在Book类中:

class Book:
    ...
    def get_title_or_nothing(self):
        if self.type == WEIRD_TYPE:
            return ""
        return self.title

更新:

class BookAdmin(admin.ModelAdmin):
    list_display = ("pk", "get_title_or_nothing")

    def get_form(self, request, obj=None, **kwargs):
        if obj.type == "1":
            self.exclude = ("title", )
        form = super(BookAdmin, self).get_form(request, obj, **kwargs)
        return form

Answer 3

class BookAdmin(admin.ModelAdmin):
    exclude = ("fieldname",)  # hide fields which you want
