python - Django过滤器: can filter with tuple?

Question

假设有一个列表

strings = ['a','b','c']

并且有两种型号

class theModel:
   theString = models.charField()

Class superModel:
   hasClass = models.ForeignKey(theModel)

有什么方法可以通过列表中的“theString”过滤 superModel 吗？

例如，这可以是一种方法(但有没有更好的方法？没有 for 循环)

tuple = []
for string in strings
   tuple.append ( theModel.objects.filter(theString = string) )

result = []
for theModel in tuple 
   result.append ( superModel.objects.filter(hasClass = theModel ) )

return result

Answer 1

你可以这样做:

theModel.objects.filter(theString__in=[1,4,7])
