Django 中的自动完成字段

Question

正在尝试在 Django 中设置 autocomplete_fields。

我有以下型号：

from django.db import models
 class Genre(models.Model):
   title = models.CharField(max_length=255)


class Movie(models.Model):
  title = models.CharField(max_length=255)
  year = models.IntegerField()
  time = models.CharField(max_length=255)
  director = models.CharField(max_length=255)
  genre = models.ManyToManyField(Genre)  
  image = models.ImageField(upload_to='images/')
  actors = models.TextField()
  summary = models.TextField()

admin.py:

from django.contrib import admin
from .models import Movie, Genre


class SettingAdmin(admin.ModelAdmin):
  search_fields = ['genre']


class MovieAdmin(admin.ModelAdmin):
  autocomplete_fields = ['genre']


admin.site.register(Movie, MovieAdmin)
admin.site.register(Genre)

错误信息：

我用来自 django.contrib.auth.models 的用户模型尝试了这段代码，它成功了。我用来自 django.contrib.auth.models 的用户模型尝试了这段代码，它成功了。

如错误消息所述：
您需要在 Genre 管理中定义 "search_fields"，因为您使用 autocomplete_fields = ['genre']、
并且不要忘记用它注册 Genre 模型。

class GenreAdmin(admin.ModelAdmin):
  search_fields = ['title']

admin.site.register(Genre, GenreAdmin)
