Django Rest Framework use DjangoModelPermissions on ListAPIView

@Yannic Hamann's solution has a small bug. It overwrites parent's perms_map['GET'].

As follows, A dictionary overring need deepcopy.

class CustomDjangoModelPermission(permissions.DjangoModelPermissions):

    def __init__(self):
        self.perms_map = copy.deepcopy(self.perms_map) # you need deepcopy when you inherit a dictionary type 
        self.perms_map['GET'] = ['%(app_label)s.view_%(model_name)s']

---

dictionary overring test

class Parent:
    perms = {'GET':'I am a Parent !'}

class Child(Parent):
    def __init__(self):
        self.perms['GET'] = 'I am a Child !'

dictionary overring result

>>> print(Parent().perms['GET'])
I am a Parent !

>>> print(Child().perms['GET'])
I am a Child !

>>> print(Parent().perms['GET'])
I am a Child ! # Parent's perms is overwritten by Child.
       ^^^^^  

Ouch, that was easier than I thought:

class CustomDjangoModelPermission(permissions.DjangoModelPermissions):

    def __init__(self):
        self.perms_map = copy.deepcopy(self.perms_map)  # from EunChong's answer
        self.perms_map['GET'] = ['%(app_label)s.view_%(model_name)s']
