Django管理中的搜索模型

Question

有一个订单模型，其中包含信息的新订单下降，如图1所示

部分信息是运动鞋的型号，有时这些运动鞋需要更正，现在这是以表格、照片2和照片3的形式完成的，有很多运动鞋，在这个下拉列表中滚动需要很长时间，有没有办法通过输入文本进行搜索，比如搜索字段

管理员

class SuitItemInOderInline(admin.TabularInline):
    model = SuitInOder
    extra = 0

class SuitOrderAdmin(admin.ModelAdmin):
    inlines = [SuitItemInOderInline]
    list_display = ('inst', 'created')
    list_filter = ('status',)


class Meta:
    model = OrderSuit
    

admin.site.register(OrderSuit, SuitOrderAdmin)

models.py

class SuitInOder(models.Model):
    order = models.ForeignKey(OrderSuit, on_delete=models.CASCADE, verbose_name='Заказ', related_name='ordered_item')
    item = models.ForeignKey(SuitItem, on_delete=models.CASCADE, verbose_name='Костюм', related_name='spb_item')

    def __str__(self):
        return f'{self.order} | {self.item.model.id} --- {self.item}'

    def save(self, *args, **kwargs):
        not_available = ['new', 'in_progress', 'completed']
        if self.order.status in not_available:
            self.item.in_stock = False
        else:

        verbose_name_plural = 'Костюмы в заказе'

class OrderSuit(models.Model):
    NEW = 'new'
    IN_PROGRESS = 'in_progress'

    CANCELED = 'canceled'

    choises = (

        (IN_PROGRESS, 'В работе'),
        (COMPLETED, 'Выполнен'),
        (CANCELED, 'Отменен')
    )

    name = models.CharField(max_length=32, verbose_name='Имя', blank=True)

    status = models.CharField(max_length=32, choices=choises, null=True, verbose_name='Статус заказа')
    created = models.DateTimeField(verbose_name='Время заказа', editable=False, default=datetime.now()+timedelta(hours=3))


    def __str__(self):
        return f'{self.name}'

    def save(self, *args, **kwargs):
        self.created = datetime.now() +timedelta(hours=3) 
        if self.id:
            items = self.ordered_item.all()
            for item in items:
                item.save()

        super(OrderSuit, self).save(*args, **kwargs)

    class Meta:
        verbose_name = 'Заказ костюма'
        verbose_name_plural = 'Заказы костюмов'

Answer 1

如果这些是foreignKey字段，请使用raw_id_字段，以便您可以在另一个窗口中搜索它们，这将加快加载速度

Answer 2

Photo1 需要使用autocomplete_字段并注册一个新模型，例如SuiteSearch，它有一个指向模型名称的搜索字段

管理员

class SuitSearch(admin.ModelAdmin):
   search_fields = ('model__name',)
    
   class Meta:
       model = SuitItem

admin.site.register(SuitItem, SuitSearch)        


class SuitItemInOderInline(admin.TabularInline):
    model = SuitInOder
    autocomplete_fields = ('item',)
    extra = 0

class SuitOrderAdmin(admin.ModelAdmin):
    inlines = [SuitItemInOderInline]
    list_display = ('inst', 'created')
    list_filter = ('status',)


    class Meta:
        model = OrderSuit
        

admin.site.register(OrderSuit, SuitOrderAdmin)
