Django 管理员“是一个”关系

发布于 2024-12-03 14:32:24 字数 743 浏览 0 评论 0原文

我在 Django 方面有丰富的经验，但我对管理应用程序非常陌生（我们通常根据项目要求将所有内容构建到页面中）。

但现在我正在开发一个需要一些管理工作的项目，而我却被困在一个部分上。

假设我有数据库模型 - 人员、学生、教师

教师和学生都是一个人（可以这么说，他们继承了这些属性）。我如何在管理视图中显示它？

这样，当有人单击添加学生时，他们只会填写学生属性，而且还会填写同一页面上的人员模型所需的属性。这可能吗？

这是模型，还有教员，但与学生类似

class Person(models.Model):
    last_name = models.CharField(max_length=50)
    first_name = models.CharField(max_length=50)
    mi = models.CharField(max_length=50)
    phone = models.CharField(max_length=20)
    cell = models.CharField(max_length=20)



class Student(models.Model):
    year = models.CharField(max_length=10)
    stud_id = models.IntegerField()
    person = models.ForeignKey(Person)
    #many to many

任何想法或进一步的问题都会很棒！

I've had plenty of experience in Django but I'm very new to the admin app (we usually build everything into the page as per project requirements).

But now I'm working on a project that requires some admin work and I'm stuck on one part.

Say I have Database models - Person, Student, Faculty

Both Faculty and Student 'is a' Person (they inherit those attributes so to speak). How can I show this in the admin view?

So that when someone clicks to add a student they fill out the student only attributes, but also the attributes required the Person model on the same page. Is this possible?

Here's the models, there's also Faculty but it's similar to Student

class Person(models.Model):
    last_name = models.CharField(max_length=50)
    first_name = models.CharField(max_length=50)
    mi = models.CharField(max_length=50)
    phone = models.CharField(max_length=20)
    cell = models.CharField(max_length=20)



class Student(models.Model):
    year = models.CharField(max_length=10)
    stud_id = models.IntegerField()
    person = models.ForeignKey(Person)
    #many to many

Any ideas or further questions would be awesome!

InlineModelAdmin 就是你的答案！
一探究竟！

这是您需要的代码：

class StudentInline(admin.TabularInline):
    model = Student

class PersonAdmin(admin.ModelAdmin):
    inlines = [
        StudentInline,
    ]

admin.site.register(Person,PersonAdmin)

InlineModelAdmin is your answer!
check it out!

Here is the code you need:

class StudentInline(admin.TabularInline):
    model = Student

class PersonAdmin(admin.ModelAdmin):
    inlines = [
        StudentInline,
    ]

admin.site.register(Person,PersonAdmin)

另一种方法是使用 Django 模型继承，如下所示：

class Person(models.Model):
    last_name = models.CharField(max_length=50)
    first_name = models.CharField(max_length=50)
    mi = models.CharField(max_length=50)
    phone = models.CharField(max_length=20)
    cell = models.CharField(max_length=20)

class Student(Person):
    year = models.CharField(max_length=10)
    stud_id = models.IntegerField()

这样，在学生管理页面中，您将从 Student 和 Person 获取所有字段，而无需 Inlines。此外，Django 将自动处理两个表之间的外键。

有关模型继承的文档。

Another way is to use Django model inheritance like this:

class Person(models.Model):
    last_name = models.CharField(max_length=50)
    first_name = models.CharField(max_length=50)
    mi = models.CharField(max_length=50)
    phone = models.CharField(max_length=20)
    cell = models.CharField(max_length=20)

class Student(Person):
    year = models.CharField(max_length=10)
    stud_id = models.IntegerField()

This way, in the Student Admin page, you will get all the fields from Student AND from Person without Inlines. Also Django will deal automatically with the ForeignKey between the 2 tables.
