ImportError: cannot import name 'ProductDetails' from 'pages.views'

[Salima Begum]

Hi all,

I have written test case for views for details page. Here is below code I have written 

```

from django.test import RequestFactory
from django.urls import reverse
from django.contrib.auth.models import User
from pages.models import vk_customer
from mixer.backend.django import mixer
import pytest

from pages.views import ProductDetails


@pytest.mark.django_db
class TestViews:

    def test_product_detail_authenticated(self):
        mixer.blend('pages.vk_master_table')
        path = reverse('detail', kwargs={'pk': 1516})
        request = RequestFactory().get(path)
        request.user = mixer.blend(vk_customer)

        response = ProductDetails(request, pk=1516)
        print(response)
        assert response.status_code == 200

```

This the error i am getting.....

Can you post your code of views.py

urls.py

 path('ProductDetails/<int:id>', views.onClickSearch.ProductDetails, name='ProductDetails'),

views.py

class onClickSearch():

    def ProductDetails(request, id):
        try:
            email = request.session.get('email')
            proddtls = vk_master_table.objects.filter(id=id).first()
            if proddtls:
                banners = Extras().bestDeals_cat(proddtls.category_desc)

        # print(banners.product_name)
        except Exception as e:

The problem is you are trying to import views from where you have not created it I guess the page is  a folder then create the views.py inside of it

Inside pages folder I already have views.py 

Thanks

You have created a class named  onClickSearch  with method  ProductDetails . So you can't import a method of a class. To use the method you need to import class.
So in place of importing  from pages.views import ProductDetails  in test_views.py do from pages.views import onClickSearch  & then use it's method as onClickSearch. ProductDetails   as per your need in your code 

[Salima Begum]

Thank you for your reply

I did that again I am getting this error
