Using Jupyter Notebook for testing

I wanted a better way to test my code so I thought why not install Jupyter Notebook on server and then test my code there.
I followed the steps from this site ( 5 easy steps to start editing python notebooks over SSH - Willem's Fizzy Logic ) . I can successfully open Jupyter Notebook but when I try to call frappe methods I get error.

import frappe

And the error:

RuntimeError Traceback (most recent call last)
in ()
----> 1 frappe.get_all(‘Item’)

/home/frappe/frappe-bench/apps/frappe/frappe/init.pyc in get_all(doctype, *args, **kwargs)
1153 if not “limit_page_length” in kwargs:
1154 kwargs[“limit_page_length”] = 0

Have you run frappe.connect() first?

Hey, guys
I was able to do that using Jupyter as you can see in the image below, I installed the Jupyter inside the virtual environment and I created the Jupyter notebook inside the sites folder and it worked

Jupyter is a really powerful tool for testing


What is baz3 ?

Thanks ever so much you two for the pointers and incentive to jump into Jupyter -

It’s been on my list so finally yesterday I got it working in a bridged network VM.

Already I am convinced it’s truly a well conceived fun tool to support code exploration, trial and error testing and development, and to document learnings.

Many scientific and academic communities use Jupyter Notebooks to share their work for eg
A gallery of interesting Jupyter Notebooks

That strategy may be productive here too?

cheers and thanks

You are welcome sir :blush:
Yeah Jupyter notebooks are perfect for sharing, testing and documenting code snippets
