    df_method = DFMethods.CREATE
    ...
```

`df_model`

```pycon
class MyView(CreateAPIView):
    permission_classes = [DFPermission]
    df_model = MyModel
    ...
```

`df_fields`

### Methods

`get_df_permissions`

```pycon
class MyView(CreateAPIView):

    def get_df_permissions(self):
        # write your logic code
        return # single permission or permissions
```

### How does it work?
First, find `df_permissions` attribute. If it 
does not exist, find `get_df_permissions` method. 
If it does not exist too, generate permissions.

First for this, collect fields that are permission 
required. Find `df_fields`, if it exist. Else get 
serializer class to get fields and get intersection
with model fields.

Then, generate required perms using fields and `df_method`.

Finally, user's permissions are checked.
