public class Foo : Object { public string prop { construct; get; } } It is meant for interospectable API using GObject Introspection. This is the recommended way for declaring classes.

As edgeapi suggests, it provides an interface for protecting attributes from end-user assignment. This makes Action Controller parameters forbidden to be used in Active Model mass assignment until they have been whitelisted. In addition, parameters can be marked as required and flow through a prede...

import javax.inject.Singleton; import dagger.Module; import dagger.Provides; @Module public class VehicleModule { @Provides @Singleton Motor provideMotor(){ return new Motor(); } @Provides @Singleton Vehicle provideVehicle(){ return new Vehicle(...

The connection between the provider of dependencies, @Module, and the classes requesting them through @Inject is made using @Component, which is an interface: import javax.inject.Singleton; import dagger.Component; @Singleton @Component(modules = {VehicleModule.class}) public interface Vehicl...

Now that you have every connection ready, you have to obtain an instance of this interface and invoke its methods to obtain the object you need: VehicleComponent component = Dagger_VehicleComponent.builder().vehicleModule(new VehicleModule()).build(); vehicle = component.provideVehicle(); Toast.m...

Django REST Framework has some authentication methods already built in, one of them is Token based, so first thing to do is to tell our project we’re going to use rest framework’s authentication. Open settings.py file and add the highlighted line. INSTALLED_APPS = ( 'django.contrib.admin', ...

Token authentication functionality assigns a token to a user, so each time you use that token, the request object will have a user attribute that holds the user model information. Easy, isn’t it? We’ll create a new POST method to return the token for this user, as long as the request holds a correc...

Let’s create a new View that requires this authentication mechanism. We need to add these import lines: from rest_framework.authentication import TokenAuthentication from rest_framework.permissions import IsAuthenticated and then create the new View in the same views.py file class AuthView(AP...

If a curl would be run against this endpoint curl http://localhost:8000/auth/ op : {"detail": "Authentication credentials were not provided."}% would return a 401 error UNAUTHORIZED but in case we get a token before: curl -X POST -d "user=Pepe&password=aaaa&qu...
