get data about XBlocks with Django REST framweork

[chemseddine zaafrane]

I created a new model inside xblock-sdk/models.py file called scenarios with multiple fields and then serialized them so i can access them using django rest framwork,

#models.py
class Scenarios(models.Model):
    description = models.TextField()
    XBlock_id = models.CharField(max_length=100)

    def __repr__(self):
        return u"<description={self.scenario} " \
            "XBlock_id={self.scenario_id}>".format(self=self)

#serializer.py
class xblockSerializer(serializers.ModelSerializer):
    class Meta:
        model = Scenarios
        fields = '__all__'

the purpose is to get all the  data about the available xblocks. however when i access the url in django rest framework i find an empty response which seems to be logic because i only created a model and i didn't populate it with the available xblocks data.

my question is what should i do in order to get a response with the data about the xblocks.
