Writing To Another Related Table Django
I have a table that logs points a student accumulates throughout the day, during the coarse of that day students can earn recess. I have two tables one that stores points and the other that stores if a child earned recess which are just straight Boolean fields. What i am trying to accomplish. # Checks To See If a Student Gets Recess Bonus today_date = datetime.datetime.now().date() morning_recess = "" lunch_recess = "" afternoon_recess = "" if grand_total >= 20 and K8Points.objects.filter(time_frame=1).filter(created_at__date = today_date ).filter(created_at__hour__lte = 10) and K8Points.objects.filter(time_frame=2).filter(created_at__date = today_date ).filter(created_at__hour__lte = 10) and K8Points.objects.filter(time_frame=3).filter(created_at__date = today_date).filter(created_at__hour__lte = 10): morning_recess = "Bonus Won" <--- code to write to other table should be here! morning_recess is just a dictionary that is showed on my html, what should happen after bonus one is create a record in the other table which logs all the recess for all the students who won. How do i go about writing to another table ? Table: Recess Name: Date : Recess: John Smith 02-04-2020 Yes -

Django Admin actions, queryset group by values in list of many to many relationship

How is it possible to duplicate HTTP headers?
I am running Django with the help of Gunicorn behind Nginx. I was adding some headers to the response using Nginx but then I decided to write middleware in Django which will do the same. I was adding some values to the header Access-Control-Allow-Headers. I added the middleware but forgot to remove the Nginx conf which was adding the headers. So, both the layers ended up adding headers. I later checked out the response in the browser which actually surprised me. Here is the screenshot of the response, So that brings me to the question, how is this possible? Is Django's response a different object and Nginx's response different? What exactly is the structure of the response object? -
Installable plugins like in Wordpress written in Django
I am in the middle of a hobby project, and I am about to make some functions, that in the theory wouldn't be suitable for all, like a webshop add-on. It's a project to learn and have fun, but I went in some doubts, why I reach out. So let's say the standard core code is a blog, just like Wordpress. Let's then say I wanna make some plugins, that I want to be installable, but not integrated by default, so it's not filling out urls.py, without being used, as an example. How would I do this smartest? -

Django query does not update when database changes
I have a weird problem, I think it comes from the cache between django and postgres but not so sure. I have multiple tables in database but the problem only happens with one of them. Let's say the SpeakingSession table. Everytime I make a change like add a new instance, edit an instance, the call api request does not return the change; the data is only updated when I restart the apache2 server. For example: I have 7 SpeakingSession records, then I add a new one. But the print command below returns 7. class SpeakingSessionViewSet(viewsets.ModelViewSet): queryset = SpeakingSession.objects.all() def list(self, request): print(self.queryset.count()) return super(SpeakingSessionViewSet, self).list(request) So I restart the apache2 server, then it returns 8. Any idea how to fix this problem? Thank you very much! This is my model and my serializer: class SpeakingSession(models.Model): sessionDefinition = models.ForeignKey('SessionDefinition', on_delete=models.CASCADE) startTime = models.TimeField() endTime = models.TimeField() participants = models.ManyToManyField('Profile', default=None, blank=True) class SpeakingSessionSerializer(serializers.ModelSerializer): class Meta: model = SpeakingSession fields = ('id', 'sessionDefinition', 'startTime', 'endTime', 'participants') -

Django model field to image in static folder

django - how to receive a dictionary in api_view?
I have followed this article and made a sample api program. I now want to make the app receive dicts(json format; key&value pairs) and process them. I couldn't make it to work. I have made an app and here is the code in views.py of the app of my project. from django.shortcuts import render from django.http import Http404 from rest_framework.views import APIView from rest_framework.decorators import api_view from rest_framework.response import Response from rest_framework import status from django.http import JsonResponse from django.core import serializers from django.conf import settings import json # Create your views here. @api_view(["POST"]) def IdealWeight(heightdata): try: height=json.loads(heightdata.body) weight=str(height*10) return JsonResponse("Ideal weight should be:"+weight+" kg",safe=False) except ValueError as e: return Response(e.args[0],status.HTTP_400_BAD_REQUEST) this is made to take a single value and return the value multiplied by 10; and this works with no problems. here is what i tried to use a json format call(a dict): in try, i made changes like: a_dict = json.loads(heightdata.body) weight = a_dict['a']+a_dict['b] it doesn't work for: {'a':1,'b':2} what changes do i make to use a dict and return a list. -

Could I use the gmail API to send mail instead of djangos send_mail() function?
I've been trying to find out how to keep track of how many emails I'm allowed to send in any given day through the gmail SMTP server. I've read that through gmail SMTP you can send 150-200 emails a day but there is no way to keep track unless maybe you make a model or a few functions to attempt to keep track and manage the amount of emails that are sent (No idea if the functions would work instead of having to use a model). I looked into their API and noticed they don't have a convenient way to keep track of how many emails you've sent in a day there either. So I was wondering if I could just write a few functions to interact with the API and send it through there rather than through the SMTP server. If I could do that then I wouldn't have to worry about keeping track of how many emails are sent. I'm only sending a max of 400 emails total and I don't think I would hit the daily limit but it's good to prepare for the worst and hope for the best. I don't need any help with the … -

What is the simplest way to include a hidden field when using Django's generic editing views

I thought something like: fields['rating'].widget = forms.HiddenInput() might work, but of course it doesn't. Any ideas? -

In Django, what is a function that an output safe YAML data?

Django-CMS: Is there any user permissions arrangement to ONLY allow logged in users to switch between viewing Published / Live page content?
I want to create a User Group which can view the unpublished version of a page, but not make any edits to the page content or page settings. I have partly accomplished this by creating a group with the following permissions: cms | page | Can view page cms | page | Can change page cms | page | Can edit static placeholders and setting the page-level permissions so that this group 'CAN EDIT' only. I needed to include the 'Can change page' Group permission and the page level 'CAN EDIT' permission as excluding either of them prevented the user from being able to toggle the View Published / Edit button in the toolbar. I needed to include the 'Can edit static placeholders' to view the unpublished static footer. With this permissions arrangement, this user group cannot make any changes using the front end editing functionality, but they can still use the admin interface to: change the page settings, such as the page title and slug set publishing dates Revert to live version Is there any other permission arrangement that can allow the user to toggle between the live and published page version, but prevents them from making any changes … -

Is Django 3.0 compatible with Jinja2 when rendering forms?
I am using Jinja2 (via django-jinja 2.3.1) in my Django 3.0 project. It renders the templates fine, however when I want to display a {{ form }} such as in a LoginView I get the following error: expected token 'end of print statement', got ':' I traced this back to the input widget in django/forms/templates/django/forms/widgets/input.html, which renders as follows: <input type="{{ widget.type }}" name="{{ widget.name }}" {% if widget.value != None %} value="{{ widget.value|stringformat:'s' }}" {% endif %}{% include "django/forms/widgets/attrs.html" %}> It would appear Jinja doesn't accept |stringformat:'s', is this correct? Does this mean it is not compatible with Django forms? Perhaps I am missing something?
