Library app management erp next

AttributeError: ‘LibraryTransaction’ object has no attribute ‘article’
please help me out

Hi @Sanket_Parade, may be ‘article’ field is not created in doctype and that field were used in code.

I’m assuming you’re going through the official Library Management tutorial.
Unfortunately there’s a conflict between the Article doctype in Library Management and the Article in the Education module of ERPNext.
This is a big problem overall and I created an issue to fix it DocType names should be namespace to the module they belong to · Issue #13337 · frappe/frappe · GitHub.
Please +1 the issue to increase the chance of a fix.
