I have made an Rest api on django 2.0 with works fine with one api view api/workspace

but it does not show the data with the view of the booking form . Any tips how to solve it?

from rest_framework import serializers

from workspace.models import Workspace_booking

class Workspace_bookingSerializer(serializers.ModelSerializer):
    class Meta:
        model = Workspace_booking
        fields = ( 'id','name','address','description','totalSpots','spotsTaken','location')


class Bookings_bookingSerializer(serializers.ModelSerializer):
    class Meta:
        model = Workspace_booking
        fields = ('id','date','workplaceId','people','note')
