ModelForm is creating a new record inspite of providing an instance
I am creating a ToDo list where I can create a ToDo item and provide a button against each item to update it. I am using ModelForm to save my data to DB. The update button takes me to 'update.html' with the instance of selected task. But when I update the task information and click on 'Submit', it creates a new task with the updated information and does not update the same task. Please helo me, I am stuck. views.py from django.shortcuts import render, redirect from .models import Task from .forms import * def index(request): tasks = Task.objects.all() form = TaskForm() if request.method == 'POST': form = TaskForm(request.POST) if form.is_valid(): form.save() return redirect('/') else: context = {'tasks':tasks,'form':form} return render(request,'TaskList/list.html',context) def update(request, pk): task = Task.objects.get(id = pk) if request.method == 'POST': form = TaskForm(request.POST, instance=task) if form.is_valid(): form.save() return redirect('/') else: form = TaskForm(instance = task) context = {'task':task, 'form':form} return render(request,'TaskList/update.html', context) urls.py from django.urls import path from . import views urlpatterns = [ path('', views.index, name = 'list'), path('update/<str:pk>/', views.update, name = 'update') ] update.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <form method = 'POST' action = ''> {% csrf_token … -
Python Django views .home dividing into sub classes
I'm trying to do a platform which is querying some data from different social media channels. My "Home" Class is now full of these queries and it takes up to 10 seconds to load the page. My question would be how I can divide the Home class into sub classes like this. Currently my code looks like this: def Home(Request): function1() function2() function3() function4() context{ query1: "query1", query2: "query2", query3: "query3", } return render(request, 'base.html', context) But I want to do like this: def Home(Request): function1() context{ query: "query" } return render(request, 'base.html', context) def Home-query2(Request): function2() context{ query2: "query2", } return render(request, 'base.html', context) def Home-query3(Request): function3() context{ query3: "query3", } return render(request, 'base.html', context) Other question would be, how can I first load the home class and then load each query all at the same time. So that I that load time totally is decreased. -

Django Ajax form
I want to use Ajax in Django to handle the view of my checkout form after it has been submitted. After the form is submitted, I want it to go to : return HttpResponseRedirect(reverse(str(next_page))+"?address_added=True") , i.e http://127.0.0.1:8000/checkout/?address_added=True But for some reason, it is not going there. Rather it's being going to http://127.0.0.1:8000/checkout/?csrfmiddlewaretoken=W4iXFaxwpdtbZLyVI0ov8Uw7KWOM8Ix5GcOQ4k3Ve65KPkJwPUKyBVcE1IjL3GHa&address=123+Main+Street&address2=&state=MA&country=USA&zipcode=55525&phone=%28877%29+314-0742&billing=on As a result, the form data is also not getting saved. I was thinking if it were because of the new version of Django. What I want to do is that after they submit the place order button, the form is going to be None, i.e disapper and then I would add a credit card form there for payment. But it is not happening. What is wrong here? Can anyone please help me out of this or is there a better way to do this? My forms.py: class UserAddressForm(forms.ModelForm): class Meta: model = UserAddress fields = ["address", "address", "address2", "state", "country", "zipcode", "phone", "billing"] My accounts.views.py: def add_user_address(request): try: next_page = request.GET.get("next") except: next_page = None if request.method == "POST": form = UserAddressForm(request.POST) if form.is_valid(): new_address = form.save(commit=False) new_address.user = request.user new_address.save() if next_page is not None: return HttpResponseRedirect(reverse(str(next_page))+"?address_added=True") else: raise Http404 My orders.views.py: try: address_added = request.GET.get("address_added") … -
How to implement ownership roles for specific models through DRF
Have two types of models, User and Object. Each User can have different ownership level of Object which will come attached with different permissions when accessing DRF endpoints (ownership=ManyToManyField(Object, through='UserObject')). e.g. A User with ownership.permission='Owner' for Object would have CRUD permissions while a User with ownership.permission='Manager' would only have RU permissions while a User with no ownership would have only C permissions. I'm currently storing the relationship with two tables OwnershipLevel with M2M to Permissions which states which of the CRUD permissions the role has but every API transaction is DB heavy as I have to retrieve the user permissions at the beginning. Looking for a way to lessen the load on the DB if possible, by caching role permissions on load or something. Thank you! -
Django render a DynamoDB JSON into a HTML table
I'm try to use a Django page as front-end using some AWS DynamoDB tables as back-end. To do so, I use boto3 library and it gets the data from the table correctly but I'm not able to parse the data into a HTML table. I have the following in views.py def history(request): itemsid = list() agents = list() dates = list() source = list() dynamodb_resource('dynamodb') history_table = dynamodb_resource.Table('name_of_the_table') all_items = history_table.scan() for p in all_items['Items']: itemsid.append((p['id'])), agents.append((p['agent'])), dates.append((p['date'])), source.append((p['source'])) return render(request, 'history.html', {'itemsid':itemsid, 'agents':agents, 'dates':dates, 'source':source} The issue is that I don't know how to write the html code to show a table with the rows: id, agent, date and source. I have the following in history.html <table> {% for i in itemsid %} <tr> <td>{{ i }}</td> ... but I don't know how to code it (how to loop it) to show the table with the lists as source.
