How to create a custom UI for admin interface in Django
Okay, I probably couldn't explain the issue in the title very well but I am building a Django app which will have various contributors. These contributors will not have superuser privileges but only some read/write privileges. Right now, I have a custom AdminSite which can be accessed by the Contributors. Here's the code: admin.py class ContributorAdmin(AdminSite): def has_permission(self, request): return request.user.is_active urls.py urlpatterns = [ path('admin/', admin.site.urls), path('contributor/', contrib_admin_site.urls), path('login/', loginview, name='login'), path('logout/', logoutview, name='logout'), #other paths for the app ] This is working as intended and gives the contributors access to the admin interface with limited privileges. However, what I would like to do is create a custom Admin UI (not the built-in Django one) which will be used by the Contributors. As an example, I would like to have a contributor.html in my templates which provides Admin like interface to the contributors but the styling etc. is all customized. Also, I would like to have my login and logout views to redirect to this custom page only. Right now, the login page redirects to ContributorAdmin so my custom logout view becomes useless. Is it possible to do this? Thanks in advance! -
Can I use hash partitioning on a non-primary key column in a PostgreSQL table?
I am trying to replace an existing table with a partitioned version of that table. I want the schema of the new partitioned table to exactly match the existing non-partitioned table so that I can continue to manage the table through Django migrations. My first attempt at creating the new partitioned table looked something like this: CREATE TABLE partition_test ( row_index bigint, id character varying(128) PRIMARY KEY, vendor_id character varying(128) ) PARTITION BY HASH (vendor_id); Which results in the following error: ERROR: unique constraint on partitioned table must include all partitioning columns DETAIL: PRIMARY KEY constraint on table "product_api_partition_test" lacks column "vendor_id" which is part of the partition key. I am looking for a work around that will allow me to partition on vendor_id while keeping row_index as the primary key. I tried modifying the primary key as follows, however, Django requires a primary key and does not support composite primary keys. Therefore, both of these options would result in an inconsistency between the true schema and what Django believes is the schema. CREATE TABLE partition_test ( row_index bigint, id character varying(128), vendor_id character varying(128) PRIMARY KEY (row_index, vendor_id) ) PARTITION BY HASH (vendor_id); CREATE TABLE api_partition_test ( row_index bigint, … -
Django Pagination with Titles Instead of Numbers
I have a lecture view which I have paginated to 1 lecture per page. I have created a separate list of all the lectures which I want to use as a navigation side bar to the different lectures. I want that side bar to display the lecture titles as links and not numbers. <ul class=""> {% for pg in lecture_single.paginator.page_range %} {% for lecture_x in lecture_single %} <li> <a href="?page={{ pg }}" class="btn">{{ lecture.title }}</a> </li> {% endfor %} {% endfor %} </ul> I tried using a for loops which did work in creating the links but all the lectures where being presented with the same title as opposed to a specific title for a different page -

Is this django test project rejected because of code structure?
Hello Dear Python Community, I created a django test project. the client was rejected with these reasons. Client Feedback 1 The code related to the recipe was looking fine but the use register and login code is good. It seems those API's will not even work well. So, I think we should not move forward. Client Feedback 2 Code structure does not looks good. Authentication is not implemented correctly. So, we should not move forward. Here the test project information Build a Recipe Sharing Platform 1. Framework:- Use Django framework to build the REST APIs. 2.

Reuse Django's admin form template for my own forms
When the Django admin renders one of its forms, the fields are rendered with HTML like so: <div> <div class="flex-container"> <label for="id_comment">Comment:</label> <input type="text" name="comment" class="vTextField" maxlength="200" id="id_comment"> </div> </div> When I add my own page to the admin interface and I render a form using {{ form }}, the layout is completely different, and the same field would be rendered like this: <div> <label for="id_comment">Comment:</label> <input type="text" name="comment" id="id_comment"> </div> How can I reuse Django’s form template for my own forms? This is my full HTML template: {% extends "admin/base_site.html" %} {% load i18n admin_urls %} {% block breadcrumbs %} <div class="breadcrumbs"> <a href="{% url 'admin:index' %}">{% translate 'Home' %}</a> &rsaquo; <a href="{% url 'admin:app_list' app_label=opts.app_label %}">{{ opts.app_config.verbose_name }}</a> &rsaquo; <a href="{% url opts|admin_urlname:'changelist' %}">{{ opts.verbose_name_plural|capfirst }}</a> &rsaquo; {{ title }} </div> {% endblock %} {% block content %} <form action="." method="post"> {% csrf_token %} {{ form }} <input type="submit" value="Generate codes"> </form> {% endblock %} I include this extra page in the admin by setting up get_urls in the ModelAdmin class, and returning a TemplateResponse with the form instance. -

Deploying Django Rest Framework Based Microservices That Communicate with Token Authentication
I am developing a docker based application. The application has two components. A core component (CORE) and an interface component (INTERFACE). The world communicates with the INTERFACE component. The INTERFACE component CRUD the database in the CORE component. The ultimate aim of this setup is that I might have different interface components. Also, it applies separation of concerns. When deploying the app. Using docker compose I will establish the communication between the two applications. However, the INTERFACE should communicate with the CORE using Token Based Authentication. My question is how to generate a Token for the INTERFACE inside the CORE during launch. I tried developing a script that generates the token. But it turns out the script requires some Environmental variables that Django Shell sets. -

How to integrate third party SOAP API (product data) with an eCommerce store?
I have access to a SOAP web service with over 40 thousand products and need an eCommerce store to connect the web service. The trick is that it cannot store the data locally in the eCommerce platform, and every time there is a search request, the SOAP web service must be called. Which platform would work in this case (Shopify, BigCommerce, Adobe Commerce, etc), or does it require a website built from scratch using a framework such as Django? I tried using Shopify a while back, but I couldn't find a way for it to work without storing products. -
Django apscheduler running thrice at one time
I have a scheduler code that running every minute to send notifications using fcm... I used print statements to know where the issue is, it came to be at scheduler side I saw that it was getting called thrice. I called the backgroundscheduler in apps.py, that generally runs twice so I tried with: urls, admin, models & views.py but strangely those files were also printing twice. I can't understand why... So I used File lock in apps.py: import os from django.apps import AppConfig import threading class MobileapisConfig(AppConfig): default_auto_field = 'django.db.models.BigAutoField' name = 'MobileApis' _lock = threading.Lock() _initialized = False def ready(self): with self._lock: if not self._initialized: lock_file = '/tmp/scheduler_initialized.lock' if not os.path.exists(lock_file): self.initialize_schedulers() with open(lock_file, 'w') as f: f.write('initialized') self._initialized = True def initialize_schedulers(self): from . import seduler seduler.start() seduler.start1() seduler.start2() seduler.start3() print('Schedulers started') but that doesn't seems to work even the file is created with text... The scheduler logs are 3+ times at the same time... What's The best place that will call scheduler only one time? -

Why are my ECS tasks pausing for six hours on startup?
I have a Fargate ECS task that runs a Django app via gunicorn. That task successfully started a few weeks ago and had no issues. It was then replaced by routine AWS maintenance/updates. The replacement task started successfully, but it paused during the execution of the entry point script for longer than the load balancer healthcheck grace period. The task of course failed the health check and that caused ECS to again stop and replace the task. This then happened endlessly, with each replacement task having the same issue. There have been no code changes involved in the Docker image used for the task. I obviously expected no change to the ECS task and that it would run as it did before. After implementing the ECS task deployment circuit breaker to stop the endless task replacement cycle, I left the paused (but running) ECS task alone for a while. I realized from the Cloudwatch logs that the task pauses for exactly six hours each time while in the middle of running the entry point script. Here's the entry point script: set -euo pipefail cd /home/viewer/projects/server || exit export DJANGO_SETTINGS_MODULE=viewer_server.settings export PYTHONPATH="/home/viewer/projects/server/" echo "DJANGO_SETTINGS_MODULE and PYTHONPATH set." python manage.py makemigrations python … -

For more clarification, I have created a json file by using write, but I am unsure on how to also create a CSV file during the same process.
