[Fixed]-In django app when splitting view.py file I am getting issues with url.py

In your views/__init__.py, you can fix this issue by importing views relatively:

from .viewscategory import * 
from .viewssubcategory import *
from .viewsitemgroup import *
from .viewsmaterial import *
from .viewsbomversion import *
from .viewsbom import *
from .viewsapprovedmanufacture import *

And then in your urls:

from django.conf.urls import url
from item import views

urlpatterns = [
    url(r'^approvedmanufacture/new/(?P<pk>\d+)/(?P<uri>\S+)/$', item.views.approvedmanufacture_new, name="approvedmanufacture_new"),
    url(r'^approvedmanufacture/edit/(?P<pk>\d+)/(?P<uri>\S+)/$', item.views.approvedmanufacture_edit, name="approvedmanufacture_edit"),
    url(r'^approvedmanufacture/delete/(?P<pk>\d+)/(?P<uri>\S+)/$', item.views.approvedmanufacture_delete, name="approvedmanufacture_delete"),
    url(r'^approvedmanufacture/approvedmanufacture_details/(?P<pk>\d+)$', item.views.approvedmanufacture_details, name="approvedmanufacture_details"),
]
