Nested Values Json and Python
I have a JSON output im getting from an API and im trying to extract the nested values from 'rows' and to access 'cells' key within rows. Here is the JSON output "rows": [ { "id": 6770063759566724, "rowNumber": 1, "expanded": true, "createdAt": "2022-01-27T17:04:11Z", "modifiedAt": "2022-01-27T17:04:11Z", "cells": [ { "columnId": 2775064444725124, "value": "Smith", "displayValue": "Smith" }, { "columnId": 7278664072095620, "value": "John", "displayValue": "John" }, { "columnId": 1649164537882500, "value": 12.0, "displayValue": "12" }, { "columnId": 6152764165252996, "value": "Gilbert", "displayValue": "Gilbert" }, { "columnId": 3900964351567748, "value": "Webhook Test", "displayValue": "Webhook Test" } ] }, Here is my code I need each columnID within cells and the value within cells.

Modifying the root folder only for one view or specific template (django, jquery, html)
I am trying to figure it out for several days, I am running out of time. I would need to make this works without changing the "<a href='/about'>About Text</a>" part (please, see code below). Basically, once the content is parsed, the link will reference to https://www.myhost.com/about, I would need to change that to https://www.myhost.com/something_more/about. I can not change the site root, I would to do it inside this specific view, the HTML template, or the jquery used (if there is a way to do it). I tried different things but without success. This is the code of the template: <div id="contents"></div> <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script> <script> $(document).ready(function () { var iframe = document.createElement("iframe"); $('#contents').append(iframe); iframe.contentWindow.document.open(); iframe.contentWindow.document.write("<a href='/about'>About Text</a>"); iframe.contentWindow.document.close(); }); </script> This is the view: def this_view(request): return render(request, 'my_app/this_view.html') Thank you, I appreciate any help. -
Django + Ajax: why does it redirect to a new URL and renders the response on browser?
Based on my understanding, ajax could be used to prevent the page from reloading/refreshing/redirecting after submitting a request to the server. However, my code will redirect to display the JSON response. I used e.preventDefault() and it didn't work. Is there anything that I am doing wrong? My Django code looks like this: views.py: def projects(request): if request.method == 'POST': task_id = request.POST.get('task_id') myUser = User.objects.get(pk=request.user.id) myTask = Task.objects.get(pk = task_id) myTask.claimed.add(myUser) #add the user to the task return JsonResponse({'status': 'ok'}) projects = Project.objects.all() tasks = Task.objects.all() open_tasks = tasks.filter(status='Created') proj_dict = {} context = { 'projects' : projects, 'tasks' : tasks, 'open_tasks' : open_tasks, } return render(request, 'projects/projects.html', context) My HTML: <form action="{% url 'projects:' %}" method="POST" class='join-form' id='{{task.id}}'> {% csrf_token %} <input type="hidden" name="task_id" value={{task.id}}> <button type="submit" class=" claim-font claim-button"> Join </button> </form> Tha ajax call: <script> $(document).ready(function () { $('#join-form').on('submit', function (e) { e.preventDefault(); e.stopPropagation(); const url = $(this).attr('action'); console.log("here we are"); const task_id = $(this).attr('id'); $.ajax({ type: 'POST', dataType: "json", headers: { 'X-CSRFToken': csrftoken }, url: url, data: { csrfmiddlewaretoken: '{{ csrf_token }}', task_id: task_id, }, success: function (response) { alert(data); console.log("here we are"); }, error: function (response) { console.log('error', response); alert("shit") } }) return false; }); … -
django Admin site wrong foreign key values

BrowsableAPI not working with functional views
How do I make BrowsableAPI work with functional views? For example, let's say I have @api_view(['GET', 'POST']) @csrf_exempt def snippet_list(request): """ List all code snippets, or create a new snippet. """ if request.method == 'GET': snippets = Snippet.objects.all() serializer = SnippetSerializer(snippets, many=True) return JsonResponse(serializer.data, safe=False) elif request.method == 'POST': data = JSONParser().parse(request) serializer = SnippetSerializer(data=data) if serializer.is_valid(): serializer.save() return JsonResponse(serializer.data, status=201) return JsonResponse(serializer.errors, status=400) When I register in the url and acces it, the browser gives me the raw json, not the browsableapi version of it. How can I make it work? I looked up the documentation and posts but couldnt find anything, everyone is either using classes based or generics. I know this way of making views is not ideal, but I still want to know how to make a functional view "Browsable". -

Any Possibility to put condition on Password Required in Django Custom Auth?
I want the registered user to log in with the Email or PhoneNumber and the Password first. If the user forgot the Password then there should be the possibility to log in with OTP bypassing the Password which would be provided via SMS on the User Phone Number. So Is there any possibility to achieve that? Here are official docs where the password field is always required. https://docs.djangoproject.com/en/4.0/topics/auth/customizing/#a-full-example I know we can change the username to the email or for a phone number if we want but how do we put the condition to login with Password/Random OTP. So how we can achieve that? a suggestion would be appreciated. Thanks -
Can I access the users data on django admin while using django-allauth?
I am new, first question.. I have configured django-allauth on a django project. It is working fine front end. When I access the Django-admin interface with the superuser, I can access all sorts of things that django-allauth as added like : -accounts -social accounts :... -sites I cannot access to the normal user data, the one which is in a table called 'campfire-users' in the db (campfire being the name of the application). Normally it appears in a group called 'authentication and authorisation" where you find 'groups' and 'users'. I have also noticed that the name of the top level app which normally appears in the top left is not appearing 'application_name ADMIN' becomes ADMIN. Any clue ? -

Django: I am unable to login as "user" from the user login page (after manually creating user in the admin page)

Django: Parameterized expand with newly created model object doesn't work
I am trying to test some django code. I want to use parameterized.expand to provide newly created Boat model objects to the method named test_method I create these model objects Boat in the test class's setUp method. My (flawed) understanding is the following: MyTestClass.setUp is run and it creates the Boat objects into the test database test_method is run for each group of variables in the parameterized decorator. Note, the parameterized decorator references the newly created Boat objects. What actually happens: parameterized decorator is instantiated at build time, before setUp is run an error is thrown because there are no Boat objects (because setUp hasn't run yet`) Here is the code: from core.models import Boat from parameterized import parameterized class MyTestClass: def setUp(self): Boat.objects.create() @parameterized.expand( [ [[Boat.objects.all()], 1], ] ) def test_method(self, list_of_boats, expected_number_of_boats]): assert len(list_of_boats] == expected_number_of_boats I get the error sqlite3.OperationalError: no such table: core_boat How do I use newly created model objects with parameterized.expand?
