Question: using primarykeyrelated for post and string for get call in django rest framework
I have a model in which some fields are a foreign key to another model. Hence while django error creating the object of that model I have to use primary key but while calling get api I need to show those fields as stringrelated field. How to achieve that??
class Example(models.Model): tour = models.ForeignKey( Package, on_delete=models.CASCADE, null=True, related_name="example" ) site = models.ForeignKey( Destination, on_delete=models.CASCADE, null= True, related_name= "example", ) location = models.CharField(blank=True) /...........other fields........../
class ExampleSerializer(serializers.ModelSerializer): # tour = serializers.StringRelatedField() # site = serializers.StringRelatedField() class Meta: model = OnlineClass fields = ['id','tour','site','other fields.....'] def to_representation(self, instance): data = super(ExampleSerializer, self).to_representation(instance) return data
Here while creating the example object, I need to pass tour and site as ids but while calling list method I need to show both fields as string related fields. As I define them as stringrelated field as above (later commented out) , I can create the object but those fields will django error be set as null. I don't want to make another serializer. How to achieve this??
