Question

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)

错误消息：

我尝试使用来自django.contrib.auth.models的用户模型使用此代码，并且可以正常工作。我使用django.contrib.auth.models中的User模型尝试了此代码，并且有效。

错误消息说：
您需要在流派管理员中定义“ search_fields”，因为您使用的是autocomplete_fields = ['genre']，
并且不要忘记向其注册流派模型。

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

admin.site.register(Genre, GenreAdmin)

Django中的自动填充字段
