Extend ERPNext 4.0

[Nguyen Do Le Bao]

Hi, 

Last time on ERPNext website, there was a link for tutorial on creating plugins (for example a custom DocType, or a custom Report). 

http://erpnext.org/plugins‎

With ERPNext 4.0, i supposed we should do it as an app like what was told here:

https://frappe.io/apps/frappe-framework/developer-guide/app-development

But the tutorial seems to be about create a totally new app, not extend or customise ERPNext. 

Do you guys know of any pointer for me to create a plugins or customise ERPNext ?

Thank you!

Hi Pratik, 

Is there any update on this ? 

I am customising the ERPNext version 3 latest but i am worried without using plugins if I upgrade to 4, everything will be overwritten. 

Is there a way ? Any direction separate the custom code ?

Like in version 3, i can use command to create a script @ erpnext/stock/doctype/stock_entry/stock_entry.py. Its content will be 

from __future__ import unicode_literals
import webnotes
from webnotes.utils import cint, cstr, flt
from webnotes.model.doc import Document
from webnotes.model.code import get_obj
from webnotes import msgprint, _
class CustomDocType(DocType):
def __init__(self, doc, doclist=[]):
self.doc = doc
self.doclist = doclist

Not sure how i go from here to extend the DocType's functionality. For example:

- on_submit of stock_entry I need to do some extra stuffs ... 

- can i make a normal @webnotes.whitelist() function to expose to client ? 

Of course, change the code directly to app/stock/doctype/stock_entry/stock_entry.py works as well but not safe for upgrading I supposed. 

Really appreciate any pointers! Thank you!

In version 4, you make an app for your customizations.

https://frappe.io/apps/frappe-framework/developers/guide

and plug in your server-side events via hooks.py file in your app

Hi, 

Thank you for this!!!

I tried out ERPNext 4, failed to install at first with root user (probably because of permission issue). 

After that I create separate user 'erpnext', it works! 

I know this was mentioned in ERPNext 3's installation Note but in the current instruction using frappe-bench, I don't think it's highlighted anywhere. 

Also as I follow the instruction in https://frappe.io/apps/frappe-framework/developers/guide, sometimes it causes some permission problem if using root as well. 

Maybe it should be added to frappe-bench's installation instruction ?
