I want to deploy the DB, API, and FRONT containers in the above repository to AWS ECS so that they can be operated
https://github.com/hodanov/react-django-postgres-sample-app I want to deploy the DB, API, and FRONT containers in the above repository to AWS ECS so that they can be operated. Therefore, in order to operate the containers separately, the docker-compose.yaml file was divided into containers. I pushed the container to ECR and operated it with ECS, but it stopped by all means. Where should I review it? -
Django global login required middleware error
I'm using Django to make a website In the website, users can have access to all pages only after they log in the website other than login page. So, I did pip install django-glrm and added 'global_login_required.GlobalLoginRequiredMiddleware' in MIDDLEWARE in settings.py Here is the reference https://django-glrm.readthedocs.io/en/latest/readme.html After installing, I just added @login_not_required to login function and it worked for several days. However, today I ran into an error. Not Found http://127.0.0.1:8000/accounts/login/?next=/ What is the problem? After erasing 'global_login_required.GlobalLoginRequiredMiddleware' in settings.py, it does not show the error but login required does not work of course. Please let me know it you have an idea -

how to convert a variable passed into HTML from python into HTML?
I'm learning Django. I have a views.py file that converts markdown into html. Then this is passed as a variable, called body into the following html. When I view the page, rather than converting the variable body into html, it just displays: <h1>CSS</h1> <p>Cats can run fast or slow <a href="/animals/HTML">HTML</a> page.</p> Below is my html file. I'm wondering, in order for the html to be read by the web-browser not as a string but as html, do I do something different then {{body}}? {% extends "mapper/layout.html" %} {% block title %} mapper {% endblock %} {% block body %} <h1>{{ title }}</h1> <div> {{ body }} </div> {% endblock %} -

Django Boolean Checkbox Input Field printing value='False'
I have a number of Boolean Field checkbox inputs within a form and I have noticed the following Boolean Fields (avaialble, bfbw, asp and tours) are printing a default value of 'False' whilst the remainder of the Boolean Fields (para_athlete, working_with_children) do not.

is it possible to use regular Django+templates and Django restframework+a javascript framework in the same project?
I'm just wondering since Jquery is used less and less and instead of classic use with Ajax, if it is possible to let for example React or Vue handle all of the functionality where Javascript would be needed with DRF in one hand , and consider all of it as statics. And in the other hand, keep working with Django and regular templates. i'm just asking about the possiblity to do so. -

Error: relation "django_admin_log" does not exist
When I try to log in to admin section I get the error page: http://localhost:8000/admin/ ProgrammingError at /admin/ ERROR: relation "django_admin_log" does not exist Then I noticed that 'django_admin_log' table does not exist. captured from psql I can not remember whether I accidentally removed it or not. In order to recover it I checked "django.contrib.admin" is in INSTALLED_APPS in settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'db.apps.DbConfig', 'django.contrib.postgres', 'accounts.apps.AccountsConfig', 'django.contrib.sites', 'allauth', 'allauth.account', ] and execute "python manage.py migrate admin" But still, I can not create django_admin_log table. PostgreSQL version is 12.6 I just mentioned the above settings in this question but still if more code is required then tell me I'll update my question with that information. Thank you -

How to replicate Django auth.admin groups and permissions admin page forms?

Many-To-Many - Too much data in admin page
My authors can have pseudonyms so I added a Many-To-Many relationship. class Name(models.Model): name = models.CharField(max_length=30, unique=True) ... class Author(models.Model): name = models.ManyToManyField(Name) sex = models.CharField(max_length=6, choices=[('m', 'male'),('f', 'female')]) birthday = models.DateField() birthplace = models.CharField(max_length=30) .... After adding many names it quickly becomes cumbersome to scroll and select through thousands of names when adding new author datasets via the admin page. Is there a better way to design the model, so that I can just add those few pseudonyms without this hassle? -

Django: Obtaining a QuerySet from a model of two OneToOne fields
I have the following set of models: from django.db import models from django.db.models import CASCADE class Battle(models.Model): idBat = models.UUIDField(primary_key=True) # other attributes... class Participant(models.Model): idPar = models.UUIDField(primary_key=True) # other attributes... class Event(models.Model): participant1 = models.OneToOneField(Participant, CASCADE, related_name='%(class)s_par1') participant2 = models.OneToOneField(Participant, CASCADE, related_name='%(class)s_par2') battle = models.ForeignKey(Battle, CASCADE, related_name="%(class)s_battle") # other atributes... However from a view I wish to get all Participants from a said Battle I obtained from a form. As such, I know I can obtain all Events from a Battle in this way: battle = form.cleaned_data['selected_battle'] events = battle.event_set participants = # now what?? As seen above I don't know how to correctly obtain said participants from each event of the battle. To be clear I can guarantee there will be repeated participants since an event consists of a fight between participant1/2 where one of them kills the other, and a battle is a succesion of said events until one participant remains victoriuos, thus every survivor of an event will appear again in another event in the battle. I wish to obtain all participants without said repetitions and possibly reorder and slice them using QuerySet.order_by(...)[0:N], hence the mention of QuerySet in the title. -
Django REST permission classes don't work together inside an OR but work as expected independently
I'm having troubles putting two permissions together using an OR operator.
