Use when writing Python Document Controllers for ERPNext/Frappe DocTypes. Covers lifecycle hooks (validate, on_update, on_submit), controller override, submittable documents, autoname patterns, UUID naming (v16), and the flags system. Keywords: document controller, lifecycle hook, validate, on_update, on_submit, autoname, naming series, flags, v14-v16, controller example, lifecycle hook order, when to use validate, Python DocType class.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Frappe Syntax: Document Controllers
Document Controllers are Python classes that define all server-side logic for a DocType.
EVERY DocType has exactly one controller file. The controller class extends `frappe.model.document.Document`.
## Quick Reference
```python
import frappe
from frappe import _
from frappe.model.document import Document
class SalesOrder(Document):
def autoname(self):
"""Custom naming logic. Sets self.name."""
self.name = f"SO-{self.customer_code}-{frappe.utils.now_datetime().year}"
def validate(self):
"""MAIN validation — runs on EVERY save (insert and update).
Changes to self ARE saved to database."""
if not self.items:
frappe.throw(_("Items are required"))
self.total = sum(item.amount for item in self.items)
def on_update(self):
"""After save — changes to self are NOT saved.
Use frappe.db.set_value() for post-save field changes."""
self.notify_linked_docs()
def on_submit(self):
"""After submit (docstatus 0 -> 1). Create ledger entries here."""
self.create_gl_entries()
def on_cancel(self):

How to install
mdr add impertio-studio/frappe_claude_skill_package/frappe-syntax-controllers@sha256:7377b2a0a23d45c0The line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
