I'm trying to add a search function to my website but I'm having some issues. It's currently telling me that "Search" is not defined, but I have the class in my views file. This is what I have thus far:
urls.py
from django.conf.urls import url
from . import views
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^player/(?P<pk>\d+)/$', views.player, name='player'),
url(r'^season/(?P<pk>\d+)/$', views.season, name='season'),
url(r'^seasons/$', views.seasons, name='seasons'),
url(r'^search/$', Search.as_view(), name='search'),
]
views.py
from django.shortcuts import render, get_object_or_404, redirect
from django.views.generic import ListView
from .models import Player, Season, PxS, Statistics
def home(request):
seasons = Season.objects.order_by('sid')
return render(request, 'webapp/home.html', {'seasons': seasons})
def player(request, pk):
player = get_object_or_404(Player, pk=pk)
return render(request, 'webapp/player.html', {'player': player, 'seasons': player.season_set.order_by('sid'), 'statistics': player.statistics_set.all()})
def season(request, pk):
season = get_object_or_404(Season, pk=pk)
return render(
request,
'webapp/season.html',
{'season': season, 'players': season.players.order_by('lastname')}
)
def seasons(request):
seasons = Season.objects.order_by('sid')
return render(request, 'webapp/seasons.html', {'seasons': seasons})
class Search(ListView):
template_name = 'search.html'
model = Player
context_object_name = 'list'
def get_context_data(self, **kwargs):
context = super(Search, self).get_context_data(**kwargs)
context['count'] = self.get_queryset().count()
return context
def get_queryset(self):
pobj = Player.objects.all()
var_get_search = self.request.GET.get('search_box')
var_get_order_by = self.request.GET.get('pid')
if var_get_search is not None:
pobj = pobj.filter(playername__icontains=var_get_search)
if var_get_order_by is not None:
pobj = pobj.order_by(var_get_order_by)
return pobj
Any insight is greatly appreciated. I'm kind of just piecing this stuff together little by little. Thanks!
The problem is in the urls.py
Give url(r'^search/$', views.Search.as_view(), name='search'),
instead of just Search.

do I'm trying to write the code for a social media website. I need every use link to be checked, for e.g. if the user has no followers, turn the number to 0, and if it has no followings, turn it back to 0. it works fine for certain users, but creates issues with some other ones, I will put my code below.
*UserFollowing is a model which determines who follows who.
models:
`class UserFollowing(models.Model):
user = models.ForeignKey(User, related_name="following",on_delete=models.CASCADE)
following_user= models.ForeignKey(User, related_name="followers",on_delete=models.CASCADE)
created = models.DateTimeField(auto_now_add=True)`
URLS:
from django.urls import path
from . import views
from.views import CreatePost
urlpatterns = [
path('explore/', views.Listexplore.as_view(), name='page-explore'),

]
view:
def post(self, request,**kwargs):
user2 = get_object_or_404(User, username=self.kwargs.get("username"))
try:
UserFollowing.objects.get(following_user=user2, user=request.user)
created = UserFollowing.objects.get(following_user=user2, user=request.user)
created.delete()
request.user.profile.follower -= 1

request.user.save()
user2.save()
except UserFollowing.DoesNotExist :

my_user= User.objects.get(username=self.request.user.username)
try:
UserFollowing.objects.get(following_user=context['user2'], user=my_user)
follow=True
except UserFollowing.DoesNotExist :
follow=False
context['follow']=follow
return context
the middleware i wrote:
from django.http.response import HttpResponseForbidden
from django.shortcuts import get_object_or_404
from django.http.response import HttpResponse
from django.http import HttpRequest
from .models import User,UserFollowing
def follow_middleware(get_response):
def middleware(request):
response = get_response(request)
if 'user' in request.path_info:
username=request.path_info.split('/')
username=username[2]
user2 = get_object_or_404(User, username=username)
if len(UserFollowing.objects.filter(following_user=user2)) == 0:
user2.profile.following = 0
if len(UserFollowing.objects.filter(user=user2)) == 0:
user2.profile.follower = 0
user2.save()
return response
return middleware
any help would be appreciated
edit:
i managed to fix the issue, the only problem is that if i delete all of the objects, the numbers reset only if I reload the page
what should I do?

It says that 1 test has failed in the tests.py file in the HomeTests. I am doing a product application. Here is my tests.py file.

The AttributeError says that HomeTests has no attribute Product.
and here is my views.py
from django.shortcuts import render,get_object_or_404
from django.http import HttpResponse
from .models import Product
# Create your views here.
def home(request):
products = Product.objects.all()
return render(request, 'home.html', {'products': products})
def product_topics(request, pk):
product = get_object_or_404(Product, pk=pk)
return render(request, 'topics.html', {'product': product})
In the urls.py, I have the following.
from django.conf.urls import url
from django.contrib import admin
from inventories import views
urlpatterns = [
url(r'^$', views.home, name='home'),
url(r'^products/(?P<pk>\d+)/$', views.product_topics, name='product_topics'),
url(r'^admin/', admin.site.urls),
]
I would like to know why I am getting this error and what this error means so I can fix it. I am following the tutorial at Urls
The problem is the whole of this test!
def test_home_view_contains_link_to_topics_page(self):
product_topics_url = reverse('product_topics', kwargs={'pk': self.product.pk})
self.assertContains(self.response, 'href="{0}"'.format(product_topics_url))
There is no product or response objects in self while you are calling self.response & self.product. Maybe you wanted to do something like this?:
from django.test import Client
class HomeTests(TestCase):
def setUp(self):
self.client = Client()
# the other tests
def test_home_view_contains_link_to_topics_page(self):
product = Product.objects.create(
name='name', description='descr', price=1.0, qtyOnHand=2
)
product_topics_url = reverse('product_topics', kwargs={'pk': product.pk})
response = self.client.get(url)
content = response.content.decode('utf-8')
self.assertContains(content, 'href="{0}"'.format(product_topics_url))

How to avoid this error, solutions as below:
Add {% csrf_token %} in your template
Link:csrf_token
Add #csrf_exempt on your view
Link:csrf_exempt
