Good morning! It sounds like you’re making solid progress on your FoodApp
project. The issue you’re facing with creating menu items that have foreign
key relationships can often happen due to authentication or serialization
issues in Django and DRF. Here’s a breakdown to help resolve it:
1.
*Verify Authorization (401 Error)*: Ensure your frontend is sending the
necessary authorization headers (like JWT token or session cookies)
required to access your DRF views. For example, use axios or fetch to
attach these headers properly.
2.
*Check Data Format (500 Error)*: Confirm that the payload sent from the
frontend matches the expected structure in your DRF serializer. With
foreign keys, make sure to send either:
- The primary key of the related object (e.g., restaurant_id), or
- Use DRF’s nested serializers if you’re submitting a complete
related object.
3.
*Adjust Serializers*: In DRF, specify how you handle related objects in
your serializers:
python
Copy code
class MenuItemSerializer(serializers.ModelSerializer):
restaurant_id =
serializers.PrimaryKeyRelatedField(queryset=Restaurant.objects.all())
class Meta:
model = MenuItem
fields = ['name', 'price', 'restaurant_id']
4.
*Debugging*: Set up error logging for detailed error messages,
especially if Debug is False. In Django, custom error messages can help
identify why the 500 error occurs.
5.
*Testing with DRF*: Since it works in DRF but not from the frontend,
inspect the network request in your browser's DevTools to ensure the
frontend request matches the successful DRF request format.
Let me know if you need further help with any specific part!
