I am passing an object to a template in Django but I can not call it
I am in Django, I am making a list of objects in my views.py so I can pass it to my template and show those properties in my page. I create the list of objects and their properties like this: views.py: def courseListView(request): object_list = {} courses = Course.objects.all() for course in courses: object_list[course] = { 'prog': int(lessonsCompleted.objects.filter(user=request.user.id, course=course.id).count() / course.lessons.count() * 100), 'title': course.title, 'slug': course.slug, 'thumbnail': course.thumbnail, 'get_absolute_url': '/' + course.slug, } context = { 'object_list': object_list, } return render(request, "courses/course_list.html", context) In this way I am populating a object called object_list with a number of objects I extract from my Course model. In the template I try calling the properties of the objects in object_list like this: template: {% block content %} {% load static %} <link rel="stylesheet" type="text/css" href="{% static 'css/courses.css' %}"> <div class="container d-flex justify-content-center"> <div class="row"> <h1>Cursos</h1> <div class="container-fluid mt-4 d-flex card-deck justify-content-center"> {% for object in object_list %} <div class="row justify-content-center"> <div class="col-auto mb-3"> <div class="card" style="width: 18rem;"> <img class="card-img-top" src="/static/{{ object.thumbnail }}" alt="Card image cap"> <div class="card-body"> <h5 class="card-title"><a href="{{ object.get_absolute_url }}">{{ object.title }}</a></h5> <div class="w3-light-grey w3-round-xlarge"> <div class="w3-container w3-blue w3-round-xlarge" id="progress-{{ object.slug }}" style="width:{{ object.prog }}%;">{{ object.prog }}%</div> </div> <div class="card-footer"> … -
Django aggregation of aggregation - Cannot compute Sum is an aggregate
I'm trying to perform an aggregate of an aggregate, but looks like is not possible (SQL doens't allow it) Let's start defining what contains the queryset: DW00 2020-01-01 2020-03-31 653.38 DW00 2020-01-01 2020-03-31 8,346.54 DW00 2020-04-01 2020-06-30 488.00 DW00 2020-04-01 2020-06-30 8,346.54 DW00 2020-07-01 2020-09-30 488.00 DW00 2020-07-01 2020-09-30 8,390.07 R00 2020-01-01 2020-03-31 6,877.11 R00 2020-04-01 2020-06-30 6,877.11 R00 2020-07-01 2020-09-30 6,877.11 The values are respectively: condition_type, calculation_from, calculation_to and net. Now we want sum the row that have same condition_type and same competence period (calculation_from, calculation_to) this translate to rows 1 and 2 merged together, rows 4 and 5 and finally 6 and 7. sap_payments = sap_payments.values('condition_type', 'calculation_from', 'calculation_to') \ .annotate(competence=Sum('net')) \ .order_by() This will return another queryset that contains: {'competence': Decimal('8999.92'), 'calculation_from': datetime.date(2020, 1, 1), 'condition_type': 'DW00', 'calculation_to': datetime.date(2020, 3, 31)} {'competence': Decimal('8834.54'), 'calculation_from': datetime.date(2020, 4, 1), 'condition_type': 'DW00', 'calculation_to': datetime.date(2020, 6, 30)} {'competence': Decimal('8878.07'), 'calculation_from': datetime.date(2020, 7, 1), 'condition_type': 'DW00', 'calculation_to': datetime.date(2020, 9, 30)} {'competence': Decimal('6877.11'), 'calculation_from': datetime.date(2020, 1, 1), 'condition_type': 'R00', 'calculation_to': datetime.date(2020, 3, 31)} {'competence': Decimal('6877.11'), 'calculation_from': datetime.date(2020, 4, 1), 'condition_type': 'R00', 'calculation_to': datetime.date(2020, 6, 30)} {'competence': Decimal('6877.11'), 'calculation_from': datetime.date(2020, 7, 1), 'condition_type': 'R00', 'calculation_to': datetime.date(2020, 9, 30)} Now we want calculate the days diff … -

Django: global template not found after creating settings module
I am struggling with paths in Django. I have the following directory structure: application # created by django | |--application |--apps # apps created by django's startapp command |--app_1 |-- ... |--__init__.py | |--app_2 |-- ... |--__init__.py |--__init__.py | |--settings |--__init__.py |--base.py |--development.py |--production.py |--__init__.py |--asgi.py |--urls.py |--wsgi.py | |--static |--css |--js |--fonts |--images | |--templates |--meta |--head.html |--javascript.html |--includes |--home.html | |--requirements.txt I just created the settings directory using this tutorial Improve your Django project with these best practices. So the __init__.py is has a single line from .development import *. The file development.py has from .base import * DEBUG = True and base.py includes all the stuff of the old settings.py file. After I did that, my templates are not working anymore, and I guess this will also happen to the static files.

I'm using python-social-auth but my app isn't logging out when the user logs out of Google
I have python-social-auth working to authorize my app and everything works great. I can log into my app via OAuth2 and log out via typical Django logout. My problem: if a user logs out of Google (from GMail, for example), it does not log me out of my Django app. I am still authorized as the Google user even though Google is logged out. I have tried refreshing tokens via the load strategy below to "force" a check to make sure Google is still logged in and that isn't working. social = request.user.social_auth.get(provider='google-oauth2') access_token = social.get_access_token(load_strategy()) social.refresh_token(load_strategy()) I feel like I'm going down the wrong road. All I want to do is validate that Google is logged into still so I can consider my OAuth2 session valid. Is there a way to do this integrity check? What am I doing wrong or do I need to do? My research so far suggests what I want is not even possible - I don't like that answer so hoping for a different one here. -

Make, migrate model programmatically, and reload / repopulate django application's new settings / configurations
I am making a model programmatically using the following code: modelObj = type(m.get("name"), (models.Model,), m.get("attrs")) After that I am trying to run the makemigrations, migrate, and autoreload command using the following code. def migrate_and_reload(): management.call_command("makemigrations") lm = MigrationRecorder.Migration.objects.filter(app=modelObject._meta.app_label).last() management.call_command("migrate", modelObject._meta.app_label, lm.__dict__.get("name"), "--database==test") from django.utils import autoreload autoreload.restart_with_reloader() But: And, get the Message from autoreloader that the server port is already use If I comment the autoreloader then Migration is not run into the database.
