Hello All
I am trying to code a flashcard app that connects to mongodb and displays flashcard data on a web page from mongodb. I tested the connection last week by sending data to mongodb this worked so the connection seems to be fine however my code to show the flashcards in a web page from the server does work. I post some of the code below
views.py
‘’’ from django.views.generic import ListView ‘’’
‘’’ from django.shortcuts import render’‘’
‘’’ from .models import Card, myapp_collection’‘’
‘’’ from django.http import HttpResponse’‘’
Create your views here.
‘’‘def index(request):’‘’
‘’’ return HttpResponse(“

‘’‘class CardListView(ListView):’‘’
‘’‘model = Card’‘’
‘’‘queryset = Card.objects.all().order_by(“box”, “-date_created”)[:5]’‘’
‘’'template_name = “card_list.html”
html file

Note: When posting code, templates, or error messages and tracebacks here, enclose the code between lines of three backtick - ` characters. This means you’ll have one line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted.
It’s most helpful if you put the file contents between one set of ```. Don’t do this for individual lines.
The lines of ```, must be lines by themselves and not parts of other lines. Additionally, you’ll want to ensure that you are using the backtick - ` and not the apostrophe - '.
Please fix your post, otherwise we will be unable to read your post to offer suggestions.
Hello All
I am trying to code a flashcard app that connects to mongodb and displays flashcard data on a web page from mongodb. I tested the connection last week by sending data to mongodb this worked so the connection seems to be fine however my code to show the flashcards in a web page from the server does work. I post some of the code below
views.py
from django.views.generic import ListView
from django.shortcuts import render
from .models import Card, myapp_collection
from django.http import HttpResponse
# Create your views here.
def index(request):
return HttpResponse("<h1>App is running</h1>")
class CardListView(ListView):
model = Card
queryset = Card.objects.all().order_by("box", "-date_created")[:5]
template_name = "card_list.html"
def card_list(request):
cards = Card.objects.all() # Retrieve all cards from MongoDB
return render(request, 'card_list.html', {'cards': cards})
#
# def get_all_myapp(request):
# myapp = myapp_collection.find()
# return myapp
#class CardListView(ListView):
# model = Card
## queryset = Card.objects.all().order_by("box", "-date_created")
# template_name = "card_list.html"
html file
<!-- cards/templates/cards/card_list.html -->
{% extends "myapp/base.html" %}
<h1>Card List</h1>
<ul>
{% for card in object_list %}
<li>{{ card.your_field_name }}</li> <!-- Make sure 'your_field_name' is a valid field of the Card model -->
{% endfor %}
</ul>
models.py
# Import necessary modules
from django.db import models
from . import db_con
# Access the 'myapp' collection from the database using db_con
myapp_collection = db_con.db['myapp']
class Card(models.Model):
BOX_CHOICES = (
('A', 'Box A'),
('B', 'Box B'),
('C', 'Box C'),
)
# Fields for the Card model
front_text = models.CharField(max_length=255)
back_text = models.CharField(max_length=255)
box = models.CharField(max_length=1, choices=BOX_CHOICES)
date_created = models.DateTimeField(auto_now_add=True)
def __str__(self):
return f"Card ({self.id}) in {self.get_box_display()}"
So fare as I am aware the mongodb connection seems to be working I just cannot get the flashcards to appear in the web page the file type is csv.
Which view are you running?
- What url is being invoked?
- What’s its definition in your urls.py?
The view.py posted is the only view that I have for the app. the url being invoked should be cardlist.html. below I have posted the urls.py for the application and for the app.
urls.py for application
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('myapp.urls')),
]
urls.py for myapp
from django.urls import path, include
from . import views
from django.views.generic import TemplateView
from .views import CardListView
urlpatterns = [
path('', views.CardListView.as_view(), name='card_list'), # URL for card list view (root)
# path('', include('myapp.urls')),
]
models.py
from django.views.generic import ListView
from django.shortcuts import render
from .models import Card, myapp_collection
from django.http import HttpResponse
# Create your views here.
def index(request):
return HttpResponse("<h1>App is running</h1>")
class CardListView(ListView):
model = Card
queryset = Card.objects.all().order_by("box", "-date_created")[:5]
template_name = "card_list.html"
def card_list(request):
cards = Card.objects.all() # Retrieve all cards from MongoDB
return render(request, 'card_list.html', {'cards': cards})
#
# def get_all_myapp(request):
# myapp = myapp_collection.find()
# return myapp
#class CardListView(ListView):
# model = Card
## queryset = Card.objects.all().order_by("box", "-date_created")
# template_name = "card_list.html"
You are not showing that you have a url defined for “cardlist.html”
Your template shows:
But you do not have a field named your_field_name in your Card model, so there’s nothing to render here.
So far as I can see I have cardListView as the url to be invoked is it written wrong?
Have you worked your way through the Official Django Tutorial? If not, you should - that’s the best place to get started with understanding the relationships between URLs and views.
If you have, then I suggest you review the work you did on part 1 and part 3 regarding URL configuration, along with the URL docs at URL dispatcher | Django documentation | Django and django.urls functions for use in URLconfs | Django documentation | Django to understand how URLs relate to views.
