Ajax or Django Rest Framework is acting weird with Post Data
I am building a Kanban Board with jQuery / JS Frontend and Django / DRF Backend. I am sending a POST AJAX Request to Server function login(email, password) { var d = { "email": email, "password": password } d = JSON.stringify(d) console.log(d) return $.ajax({ url: "api/accounts/login/", type: "POST", data: d, dataType: "json", }).then((response) => { var data = JSON.parse(response); return data; }).fail((response) => { return false; }) } But when the request is received by the server this {"email":"satyam@gmail.com","password":"satyam@789"} is converted to '{"email": "satyam@gmail.com", "password": "satyam@789"}': ['']}' What is the problem causing this? Is it Javascript or DRF? -

Question coherence choice techno web + Django + BD
I have had a website project for a while. I'm still in the learning phase for probably a few more weeks. I am mastery in HTML, CSS, JavaScript Vanilla, PHP, MySQL, Python. I am currently learning Django, soon the React JS JavaScript framework; AJAX; CSS -> SASS; Nginx; Gunicorn and probably UML + PostgreSQL The site I am going to develop is not yet fixed from a technical point of view. I want it to be in Python / Django, because the site will be very strongly linked to using APIs in Python (including Youtube) and will also be very much linked to a web bot written in Python (bot that provides the data in connection with the API to create the content of the pages). The site will be very automated in the production of its content (by just a web server's view, but also by adding new content). I currently only have a pretty bad estimate of how many pages the site will be able to deliver. I estimate it to be at least 1 million pages. My questions are as follows: I am already familiar with MySQL, but I think I will need several databases, many tables, … -
Can't save admin form with more than 1000 entries selected
I have a group that requires at least 1000 permissions to be chosen. This is the group before: This is what I do: And this is what happens when I save. While I can read, and understand that increasing DATA_UPLOAD_MAX_NUMBER_FIELDS to a larger value or None will resolve the issue, this is a production service, and I am not allowed to increase that value for security reasons. Since only the admin needs to handle POST requests of this size, we can ease that a bit by overriding the admin form. But how should I go about that? This is an example snippet that I have, and I don't know where I can put an override_settings(DATA_UPLOAD_MAX_NUMBER_FIELDS=None. Where can I put that? class GroupAdminForm(forms.ModelForm): class Meta: model = Group fields = '__all__' class GroupAdmin(Admin): form = GroupAdminForm list_display = ('...',) admin.site.register(Group, GroupAdmin) -
trying to show elements of a dictonary that's stored in django model

I have tried nesting a for loop but it doesn't seem to work, stating that "myModel object is not iterable" <li> {% for number in numbers_in_sortedList %} {% for item in number %} {{item.jsonM}} {% endfor %} {% endfor %} </li> Any ideas? -
Django : how to assign permissions automatically after initial migration
I'm using Django for my backend and everything's fine. But I now have to enable permissions and so on. I'm trying to assign all the permissions of an app to a group during the migration process but here is the problem : During the initial migration, the Permissions are not created yet. The reason is that in Django, they are created in a post_migrate signal. The default flow is : call migrate command it does migration things post_migrate signal is sent and Permissions records are created So I could write a post_migrate function too but, how could I be sure that it will be run after the default one that creates Permissions ? Other question : is there a better way to assign permissions automatically when an app is first migrated ? Thanks in advance :) -
python manage.py runserver not working on on localhost:8000
I am new to django and trying to run the django server for the first time. I am trying to run the command for starting a django server in a terminal, i.e. python manage.py runserver. But when I go to http://localhost:8000, it is not giving me the default django output containing a rocket like image. I even tried using http://my_ip:8000 and http://127.0.0.1:8000 but still it doesn't work.

django-paypal IPN being received but signal not activating

Django occasionally returning empty querysets
Here’s a problem that I’ve been trying to fix for a few days now: I have Django application that exposes data through a REST API, using a Postgres database. In production, the API sometimes returns empty data. To narrow down the problem, I added some logging. As it turns out, Django returns empty querysets (even though there is data), a minute later, the data is returned properly. Some hints on what may go wrong: I haven’t been able to reproduce the issue in my development setup Some (but not all) of the failing queries use queryset.union() Postgres doesn’t report any errors/warnings With Django set to debug SQL queries, the queries look fine Both Django app and Postgres DB are “dockerized”, running on Ubuntu hosts The issue occurs on all production hosts There are no special database settings Can you spot anything susceptible? Has anyone experienced a similar situation? Thanks! Any help is appreciated. PS: Here‘s an example query: FILTER_KWARGS_PUBLIC = { 'status': APPROVED, 'visibility': PUBLIC, } def collect_pieces(self, public_only=False) -> QuerySet: """ Collect pieces that have been added directly or through relation """ filter_kwargs = {} if public_only: filter_kwargs = self.FILTER_KWARGS_PUBLIC piece_ids = self.performances_relation.filter(**filter_kwargs).values_list('piece__pk', flat=True) q1 = Piece.objects.filter(pk__in=piece_ids, **filter_kwargs) queryset … -
