如何在管理中间页面中重用Django的管理外键小部件

from django.db import models

class Author(models.Model):
    name = models.CharField(max_length=100)
    # 其他字段...

class Book(models.Model):
    title = models.CharField(max_length=100)
    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    # 其他字段...

from django.contrib.admin.widgets import ForeignKeyRawIdWidget

class CustomForeignKeyWidget(ForeignKeyRawIdWidget):
    def url_parameters(self):
        # 自定义URL参数
        params = super().url_parameters()
        params.update({'custom_param': 'value'})
        return params

from django.contrib import admin

class BookAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.ForeignKey: {'widget': CustomForeignKeyWidget},
    }

admin.site.register(Book, BookAdmin)
