How can I filter a Django query with a list of values?

From the Django documentation:

Blog.objects.filter(pk__in=[1, 4, 7])

When you have list of items and you want to check the possible values from the list then you can't use =.

The sql query will be like SELECT * FROM mytable WHERE ids=[1, 3, 6, 7, 9] which is not true. You have to use in operator for this so you query will be like SELECT * FROM mytable WHERE ids in (1, 3, 6, 7, 9) for that Django provide __in operator.

From the Django documentation:

Blog.objects.in_bulk([1])
{1: <Blog: Beatles Blog>}

Blog.objects.in_bulk([1, 2])
{1: <Blog: Beatles Blog>, 2: <Blog: Cheddar Talk>}

Blog.objects.in_bulk([])
{}

Blog.objects.in_bulk()
{1: <Blog: Beatles Blog>, 2: <Blog: Cheddar Talk>, 3: <Blog: Django Weblog>}

Blog.objects.in_bulk(['beatles_blog'], field_name='slug')
{'beatles_blog': <Blog: Beatles Blog>}
