在 django 标记中将有限的查询集传递给 related_to()
我想在 django 标记中使用 lated_to() 函数，并且传递一个如下所示的查询集：
Chapter.objects.all().order_by('?')[:5] #the important thing here is the "[:5]"
我的问题是该函数显然使用 in_bunk() 函数并且您Cannot use 'limit' or 'offset' with in_bulk
如何限制我的查询集仅传递 5 个对象并同时使用 in_bunk？
我知道 related_to() 允许您传递变量 num （这是它应该返回的对象的数量），但我不希望它每次都输出相同的查询集。因此，我想到了随机排序并在将其传递给函数之前对其进行限制的想法。但正如您所看到的：有限的查询集和bunk_it并不能很好地齐头并进。
I want to use the related_to() function in django-tagging and I am passing a queryset looking like this:
Chapter.objects.all().order_by('?')[:5] #the important thing here is the "[:5]"
My problem is that this function apparently uses the in_bunk() function and you Cannot use 'limit' or 'offset' with in_bulk
How can I restrict my queryset to only pass 5 objects and at the same time make use of in_bunk?
I know that related_to() lets you pass the variable num (which is the number of objects it should return) but I don't want it to output the same queryset every single time. So i came up with the idea of ordering it randomly and limiting it before it was passed to the function. But as you can see: limited querysets and bunk_it doesn't go hand in hand very well.

我找到了一个解决方案，尽管它不是最好的，并且它处理了不必要的数据。我只需运行与当前实例相关的模型的所有实例，然后随机排序并随后切片：
I found a solution though it wasn't the best and though it processes unnecessary data. I simply run through all instances of the model related to the current instance and I then sort randomly and slice afterwards:
