🚀 Feature: Python SDK does not validate row data against table schema before insertion #134
Description
🔖 Feature description
The Python SDK allows defining table schemas (required fields, data types, defaults), but create_row does not perform any client-side validation against this schema.
As a result, issues like missing required fields or incorrect data types are only caught server-side after the API request, leading to delayed and less clear errors.
🎤 Pitch
The Python SDK already has full knowledge of the table schema at creation time (required fields, data types, defaults), but this information is not used when inserting rows. This leads to avoidable runtime errors that are only discovered after a network request.
-
Adding optional client-side validation would:
-
Catch simple mistakes (missing required fields, wrong data types) immediately
-
Provide clearer, Python-native error messages
-
Reduce unnecessary API calls and debugging time
-
Improve onboarding and overall developer experience
This does not replace server-side validation, but complements it by shifting basic checks closer to the developer.

Hi @eldadfux @stefanslo @PineappleIAP! 👋
I'd love to work on implementing client-side row validation against the table schema for the Python SDK.
Proposed Implementation Plan:
appwrite/services/databases.py(or a dedicated validation utility) that inspects required fields, expected primitive types (string,integer,float,boolean), and default values prior to sending the network request.AppwriteExceptionwith clear, descriptive details (e.g.,Missing required attribute: 'title'orInvalid type for 'age': expected int, got str) before dispatching the HTTP call.test/services/test_databases.pyverifying valid row payloads, missing required attributes, and type mismatches.Could you please assign this issue to me? Thanks!

Hi maintainers,
I'd like to contribute to this issue and help improve the Python SDK.
I noticed that this repository is marked READ-ONLY and the SDK is auto-generated. Should this change be implemented in the Appwrite SDK Generator instead?
I also noticed that another contributor has expressed interest in working on this issue, so I don't want to duplicate their efforts.
Could you please clarify the recommended contribution path and whether there is an opportunity for me to help?
Thank you!
