我正在创建一个Django应用程序,其中所有模型可以按照用户设置的顺序相互关联。我正在使用GenericForeignKeys设置所有这些。踢球者是我需要能够支持这些类型的关系/管理员的多个集合。因此,一个对象可以有一个以上的相关对象集合。
有没有人知道这种情况下一个好的GenericForeignKey小部件?最好是填充管理表单的自动填充搜索,因为我最终可能会有大量的对象。
这是我的应用程序的代码,可以更好地了解我的意思。
from django.contrib import admin
from django.contrib.contenttypes import generic
from django.contrib.contenttypes.models import ContentType
from django.db import models
from django import forms
# Models
class Base(models.Model):
title = models.CharField(max_length=255)
class Meta:
abstract = True
def __unicode__(self):
return self.title
class Related(Base):
""" A generic relationship model for relating resources.
"""
order = models.IntegerField(blank=True, null=True)
limit = models.Q(model = 'Apple') | models.Q(model = 'Orange') | models.Q(model = 'Pear')
content_type = models.ForeignKey(ContentType, related_name="related_%(class)s")
object_id = models.PositiveIntegerField(db_index=True)
object = generic.GenericForeignKey()
related_content_type = models.ForeignKey(ContentType, related_name="related_related_%(class)s", limit_choices_to = limit)
related_object_id = models.PositiveIntegerField(db_index=True)
related_object = generic.GenericForeignKey('related_content_type', 'related_object_id')
class Meta:
ordering = ('order',)
abstract = True
def __unicode__(self):
return self.object.title
class FreshFruit(Related):
pass
class OldFruit(Related):
pass
class Apple(Base):
pass
class Orange(Base):
pass
class Pear(Base):
pass
# Admin classes
class FreshFruitInline(generic.GenericStackedInline):
model = FreshFruit
extra = 1
# Admin classes
class OldFruitInline(generic.GenericStackedInline):
model = OldFruit
extra = 1
class AppleAdmin(admin.ModelAdmin):
inlines = [FreshFruitInline, OldFruitInline,]
admin.site.register(Apple, AppleAdmin)
class OrangeAdmin(admin.ModelAdmin):
inlines = [FreshFruitInline, OldFruitInline,]
admin.site.register(Orange, OrangeAdmin)
class PearAdmin(admin.ModelAdmin):
inlines = [FreshFruitInline, OldFruitInline,]
admin.site.register(Pear, PearAdmin)
我进行了搜索和搜索,并找到了为ManyToMany关系执行此操作的小部件,但对我的情况没有任何帮助。
感谢您抽出时间来研究这个问题。
