Django 中的自动完成字段

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)

错误信息：

我使用 django.contrib.auth.models 中的用户模型尝试此代码并且它有效。我使用 django.contrib.auth.models 中的用户模型尝试此代码并且它有效。

正如错误消息所说：您需要在Genre admin 中定义“search_fields”，因为您使用autocomplete_fields = ['genre']，并且不要忘记向其注册 Genre 模型。class GenreAdmin(admin.ModelAdmin):&nbsp; search_fields = ['title']admin.site.register(Genre, GenreAdmin)
