  1. How to display all model fields with ModelSerializer?

    You could use fields = '__all__' to get all your fields or you could specify if you want a limited number of fields to be returned.

  2. display all model fields with ModelSerializer

    You could use fields = '__all__' to get all your fields or you could specify if you want a limited number of fields to be returned.

Method 1

You could use fields = '__all__' to get all your fields or you could specify if you want a limited number of fields to be returned.

But this returns the id value for the foreign key field i.e. producer in your case. To get all the fields for producer, you need to create a serializer class for that too.

So your updated serializers.py should be:

class ProducerSerializer(ModelSerializer):
    class Meta:
        model = Producer

class CarSerializer(ModelSerializer):
    producer= ProducerSerializer(read_only=True)

    class Meta:
        model = Car
        fields = ('producer', 'color', 'car_model', 'doors', )

Method 2

if you want all fields to be included in the serializer you can use fields =’_ all _’

class CarSerializer(serializer.ModelSerializer):
      class Meta:
           fields = '__all__'
           model = Car

but this approach is not recommended. we should always explicitly specify all fields. this is because it gives us control over fields displayed. if we don’t want a fields data to be displayed we can avoid that.

 class CarSerializer(serializer.ModelSerializer):
          class Meta:
               fields = ['name','color','company','price']
               model = Car
