如何隐藏 django-admin 中的某些字段? [英] How to hide some fields in django-admin?

问题描述

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，当保存的书的类型为 1 时，我想隐藏书名(在书详细信息表单中).如何以最简单的方式做到这一点?

I have a simple class in models.py. In admin I would like to hide title of the book (in book details form) when type of the saved book is 1. How do this in a simplest way?

推荐答案

你要在你的模块中创建admin.py(可能是book)

You are to create admin.py in your module (probably book)

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

在书籍类中:

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
