Django : Cannot import modules

Question

I am trying to import a module in my views.py as

from django.shortcuts import render

# Create your views here.
from viewcreator import Builder
import json
def index(request):

    a,b=Builder.buildChartJSON()
    print(json.dumps(a))  
    print(json.dumps(b))
    return render(request, 'hdfsStats/hdfscharts.html',
                  {'sourcepoints': a, 'sizepoints': b})

and here is how my project setup looks like

why cant i import the modules in my view? I do not want to create these classes in the models.py. These classes are just meant to run some calculations and return two json objects, which i then feed to my webpage

here is my settings.py

Update

current structure

and my views.py

from django.shortcuts import render

# Create your views here.
from .src.viewcreator import Builder
import json
def index(request):

    a,b=Builder.buildChartJSON()
    print(json.dumps(a))  
    print(json.dumps(b))
    return render(request, 'hdfsStats/hdfscharts.html',
                  {'sourcepoints': a, 'sizepoints': b})

but now i get

from propreader import ReadProp
ImportError: No module named 'propreader'

basically, i have four packages

viewcreator
propreader
esconnector
ping

the classes in these packages perform some calculations based on the properties files in the these two folders

props
resources

which i have put at the same level as src folder

Since these are one time calculations, i dont want to create models for these. What is the proper way for me to configure my Django project in this scenario? I need the Django project to host a webpage that will display the results of my calculations.

Answer 1

In your INSTALLED_APPS

INSTALLED_APPS = [
    ...,
    'HdfsstatsConfig',
]

in your views.py

from .viewcreator import Builder

UPDATE, DJANGO IMPORTS

There are 3 ways to imports module in django

1. Absolute import: Import a module from outside your current application Example from myapp.views import HomeView

2. Explicit import: Import a module from inside you current application

3. Relative import: Same as explicit import but not recommended

from models import MyModel
