Django - adjusting admin panel for users
I'm currently working on a Django project which will be available to use by several companies and their particular data about their clients. My question is if it is possible to adjust Django admin panel somehow, so that any user could log in (in this case the particular company worker) and have an access to admin tools, but only for the data related to his company (in this case the company clients)? Example: Worker of company X logs in and checks status of clients of his company, changes some data etc. At the same time worker of company Y logs in and does the same work with the clients related only to company Y. Both users see only clients related to their own company - they don't have access to other company's data. I've found something like this, but I'm not sure if it's appropriate to my situation :P -

Django - Pass values from template to views file with Drop Down URL link options
I am currently redirecting the user to payment confirmation page if cash is selected from the dropdown list. <select class="custom-select " id="payment" name= "pay_method" onchange="SelFunction()" required> <option value=""> Select the Pay Method </option> <option value="credit card"> Credit Card </option> <option value="cash"> Cash </option> </select> <script> function SelFunction() { var x = document.getElementById("payment").value; if (x == 'cash') { window.location.href = "{% url 'payment_confirmation' %}"; } }; </script> This code is not posting any values to views files.

How to keep database structure as much as possible same when switching git branches for Django project with docker containers?
We are developing a Django project using docker containers with multiple git branches. The problem we are facing is when we switch branches, automatic migrations are applied to all models when we restart the containers because of our docker configuration. We also don't want to apply manually migrations always on each change, that's why we included migration commands on the docker configuration. However, this causes some problems when we switch from a feature branch which is definitely ahead from the other one. The database structure is reverted and we are losing data. Is there any good way to keep database structure as much as possible same (superset) and not dealing with manual migrations when we switch from a feature branch to an outdated branch? Our docker configuration is as follows: version: '3.3' services: postgres: image: postgres:latest restart: always redis: image: redis:latest restart: always web: build: ./project command: bash -c "python manage.py makemigrations && python manage.py migrate --noinput && gunicorn project.wsgi -b 0.0.0.0:8000 --workers 16" volumes: - ./project:/app expose: - "8000" depends_on: - postgres - redis restart: always celery: build: ./project command: celery -A project worker -l info --concurrency=8 --max-tasks-per-child=1 volumes: - ./project:/app depends_on: - postgres - redis restart: always -
Close Bootstrap Modal On Submit with Django
I have been through pretty much every post on this forum and have not been successful at getting my modals to close after submission. data-dismiss does not work since it stops the submission before it starts. Using JavaScript code within the base html page also has not worked. Examples of posts that I have tried are here and here. My code is below. Any recommendations are appreciated.

How to dynamically swap default model manager in django?
I am creating a project in django and django rest framework. Its and api for an angular app. The database setup consists of multiple databases. one is default database, all the django tables reside in this database; rest of the databases belong to a type of a user, each user is supposed to have a separate database. So, all the user related data goes to its separate database. To implement the selecting database dynamically, user object has an extra field to store the database to write to. from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): """Custom User model.""" database= models.CharField(max_length=9) Reason for doing this was performance improvement as each database is separate, ListView and DetailView would work faster than if the data was stored in the one database only. I know I can choose a database to store by using the using method on the model manager. In the rest api things work fine and data is being stored in their separate databases, but I end up overriding methods that django has defined. Its adding development cost to the project. Foreign keys and ManytoMany keys needs to be resolved with the current database of the user, which is not happening as I … -
getting data from two different Models at the same time

Django - No Reverse Match Error - URL only works with static values
I'm working on a Django site that displays a list of projects. You go to a page, you see a project, you click it, and you can then see project details and have the option to edit the page. For each individual project, I use a template called project.html. Then on that page, I have a link to edit_project.html <a href="{% url 'profile:edit_project' project.id %}">Edit Project</a> Whenever I try to load the project page to view, I get this error: Reverse for 'edit_project' with arguments '('',)' not found. 1 pattern(s) tried: ['edit_project/(?P\d+)/$'] I checked the urls, and they seemed fine. So, I tried hard-coding a project id that I knew was in the database. For example, I called: <a href="{% url 'profile:edit_project' 5%}">Edit Project</a> instead of calling that same thing with "project.id". When I did that, the error went away. Why does this work with a hard-coded value instead of a project.id variable? I also tried deleting the database and all the migrations in case something strange was happening there. I got the same issue though. Here is the code I used to set everything up in case it is helpful. project.html {% extends "profile/base.html" %} {% block content %} … -

Django two databases (e.g. master-slave) setup results in duplicate queries
I have two databases - one is primary, the second one is replica. To read from the replica I explicitly set using statement. E.g. Object.objects.using('replica').filter(...)

DRF (Django) hierarchy structure
I need to create a hierarchy, and I added list of models, like that: class Category(models.Model): name = models.CharField(max_length=255) class Form(models.Model): parent = models.ForeignKey('Category', related_name='category', on_delete=models.CASCADE) name = models.CharField(max_length=255) class Type(models.Model): parent = models.ForeignKey('Form', related_name='form', on_delete=models.CASCADE) name = models.CharField(max_length=255) class Point(models.Model): parent = models.ForeignKey('Point', related_name='point', on_delete=models.CASCADE) name = models.CharField(max_length=255) So, please, advise how to handle this structure. I have to implement 2 cases: I need to get a record from 'point' table and it should return it with all upper hierarchy: Point-Type-Form-Category And I need to get all records from Category with full hierarchy(internal structure, which is under each record) too. So, what is the best way or instruments to implement it?
