django drf 多对多字段进行赋值

用户表----部门表是多对多关系,字段是department,
用set可以对department来进行赋值操作

is_true = UserProfile.objects.filter(username=user["user_no"]).all()
if is_true:
    is_true[0].name = user["user_name"]
    is_true[0].mobile = user["telf"]
    is_true[0].email = user["email"]
    is_true[0].position = user["position"]
    is_true[0].is_active = 1 if user["is_still"] else 0
    is_true[0].department.set(user_dict[user["user_no"]])
else:
    new_user = UserProfile(username=user["user_no"], name=user["user_name"], mobile=user["telf"],
                           email=user["email"], image="image/default.png",
                           position=user["position"],
                           is_active=1 if user["is_still"] else 0
                           )
    new_user.save()
    new_user.department.set(user_dict[user["user_no"]])
