@nnylyj do you can list all hooks, using the bellow code


frappe.get_hooks('doc_events').get('DocType').get('validate')

frappe.get_hooks('doc_events').get('*').get('validate')

Thanks!
I get the result but it’s weired.
I bind validate hooks on Purchase Order and Sales Order and a before_save on Item Price, but ONLY Item Price hooked successfully.

'doc_events': {u'Item Price': {u'before_save': [u'dmallerp.item_price_log.logger.create_item_price_log']},
  u'Purchase Order': {u'validate': [u'dmallerp.validators.hooks.validate_return_order_qty']},
  u'Sales Order': {u'validate': [u'dmallerp.validators.hooks.validate_return_order_qty']}}

using frappe.get_hooks('doc_events') and got

 {u'*': {u'after_insert': [u'frappe.email.doctype.email_alert.email_alert.trigger_email_alerts'],
  u'after_rename': [u'frappe.desk.notifications.clear_doctype_notifications'],
  u'on_cancel': [u'frappe.desk.notifications.clear_doctype_notifications',
   u'frappe.email.doctype.email_alert.email_alert.trigger_email_alerts'],
  u'on_submit': [u'frappe.email.doctype.email_alert.email_alert.trigger_email_alerts',
   u'frappe.desk.doctype.feed.feed.update_feed'],
  u'on_trash': [u'frappe.desk.notifications.clear_doctype_notifications'],
  u'on_update': [u'frappe.desk.notifications.clear_doctype_notifications',
   u'frappe.email.doctype.email_alert.email_alert.trigger_email_alerts',
   u'frappe.desk.doctype.feed.feed.update_feed'],
  u'validate': [u'frappe.email.doctype.email_alert.email_alert.trigger_email_alerts']},
 u'Address': {u'validate': [u'erpnext.shopping_cart.cart.set_customer_in_address']},
 ---LOOK_AT_HERE--> u'Item Price': {u'before_save': [u'dmallerp.item_price_log.logger.create_item_price_log']},
 u'Price List': {u'on_update': [u'erpnext.shopping_cart.doctype.shopping_cart_settings.shopping_cart_settings.validate_cart_settings']},
 u'Sales Taxes and Charges Template': {u'on_update': [u'erpnext.shopping_cart.doctype.shopping_cart_settings.shopping_cart_settings.validate_cart_settings']},
 u'Stock Entry': {u'on_cancel': [u'erpnext.stock.doctype.material_request.material_request.update_completed_and_requested_qty'],
  u'on_submit': [u'erpnext.stock.doctype.material_request.material_request.update_completed_and_requested_qty']},
 u'User': {u'on_update': [u'erpnext.hr.doctype.employee.employee.update_user_permissions'],
  u'validate': [u'erpnext.hr.doctype.employee.employee.validate_employee_role']}}

And,

  u'Purchase Order': {u'validate': [u'dmallerp.validators.hooks.validate_return_order_qty']},
  u'Sales Order': {u'validate': [u'dmallerp.validators.hooks.validate_return_order_qty']}}

LOST?

@nnylyj pass app_name="your_app_name", to get only the hooks of your app!

The result is showing all hooks in the environment

Yeah, I mean hooks were exactly defined in my app, but not shown in environment.

So, just pass

frappe.get_hooks('doc_events', app_name="dmallerp").get('*').get('validate')

You need to go to user menu and click on “Reload”. It will clear frappe’s cache where hooks are cached.

You can also do that from the command line using:
bench --site SITENAME clear-cache

In [27]: frappe.get_hooks('doc_events', app_name="dmallerp").get('*').get('validate')

Replace the “*” by the doctype names, or store frappe.get_hook in a variable, and inspect it
