传递对象列表作为Django中的manytomany字段类型

Question

I want to know if we can pass a list of objects (in this case list of blog objects to the Entry model as the manytomany object parameter). On doing so i am not getting the desired result. Please help.

models.py

class Blog(models.Model):
    id=models.AutoField(primary_key=True)

class Entry(models.Model):
    id=models.AutoField(primary_key=True)
    blogs=models.ManyToManyField(Blog)

views.py

def something(request):
    list=[]
    for i in range(10):
        list.append(Blog.objects.get(pk=i))
    ans=Entry.objects.filter(blogs=list)
    print(ans)
    #some other work.

Answer 1

First thing you can do is replace your for iterator with this:

blogs = Blog.objects.filter(id__range=[0, 10])

Second, you can use the lookup feature using __in :

ans = Entry.objects.filter(blogs__in=blogs)

So your final views.py could look like this:

def something(request):
    blogs = Blog.objects.filter(id__range=[0, 10])
    ans = Entry.objects.filter(blogs__in=blogs)
    print(ans)
    #some other work.
