Django Admin:将外键的选择框更改为搜索自动完成功能，例如搜索对象 [英] Django Admin: change select box for foreign key to search autocomplete, like search objects

问题描述

Django管理面板在模型的对象列表上具有自动搜索功能，并带有search_fields，但是现在我有3000个用户.手动添加用户很难通过选择框进行；我需要像搜索字段一样的行为来选择用户foreinkey User.

The Django admin panel has a search autocomplete with search_fields on the list of objects of a model, but right now I have 3000 users. To add a user manually is dificult with the selectbox; I need the same behavior like the searchfields for selecting a user foreinkey User.

如何在表单中包括Django搜索功能，以便在管理面板中进行编辑?

How can I include the Django search feature on the form for editing inside the admin panel?

from myapp.models import Red 
from django.contrib.auth.models import User

class Red(models.Model):
    customer = models.ForeignKey(User, verbose_name="Cliente")
    pub_date = models.DateTimeField(default=datetime.now, blank=True)

推荐答案

从Django 2.0开始，您可以使用

Since Django 2.0, you can use autocomplete_fields to generate autocomplete fields for foreign keys.

class UserAdmin(admin.ModelAdmin):
    search_fields = ['username', 'email']

class RedAdmin(admin.ModelAdmin):
    autocomplete_fields = ['customer']
