Question

我必须在不同的模型中上课。第一个，名为Audiobook

from django.db import models
from labels.models import Label


class Audiobook(models.Model):
    """the audiobook object"""
    title = models.TextField()
    content = models.TextField()
    cover = models.FilePathField()
    playtime = models.TextField()
    moneyLink = models.TextField()
    status = models.BooleanField(default=False)
    label = models.ForeignKey(Label)

第二个，名为Label

from django.db import models


class Label(models.Model):
    """the label object"""
    name = models.TextField()
    description = models.TextField()
    status = models.BooleanField(default=False)

在有声读物中，我在Label对象上有一个ForeignKey。

现在是管理类。

audiobook_admin：

from audiobooks.models import Audiobook
from labels.models import Label
from django.contrib import admin


class LabelInline(admin.TabularInline):
    model = Label


class AudiobookAdmin(admin.ModelAdmin):
    fieldsets = [
        (None, {'fields': ['title']}),
        (None, {'fields': ['content']}),
        (None, {'fields': ['cover']}),
        (None, {'fields': ['playtime']}),
        (None, {'fields': ['moneyLink']}),
        (None, {'fields': ['status']}),
        (None, {'fields': ['label']})
    ]
    inlines = [LabelInline]

admin.site.register(Audiobook, AudiobookAdmin)

标签管理类：

from labels.models import Label
from django.contrib import admin


class LabelAdmin(admin.ModelAdmin):
    fieldsets = [
        (None, {'fields': ['name']}),
        (None, {'fields': ['description']}),
        (None, {'fields': ['status']})
    ]

admin.site.register(Label, LabelAdmin)

标签部分都很好。

我必须做些什么才能在Audiobook管理页面中使用Dropdown控件选择标签？如果我不想输入新的Audiobook，我会出现以下错误：

Exception Value: <class 'labels.models.Label'> has no ForeignKey to <class 'audiobooks.models.Audiobook'>

感谢您的帮助！

Answer 1

Dropdown控件是ForeignKey的默认控件。

默认管理员配置应该有效：

from labels.models import Label
from audiobooks.models import Audiobook
from django.contrib import admin

admin.site.register(Label)
admin.site.register(Audiobook)

django管理页面下拉键外键
