I need some help from you folks! I am beginner and I am working on Django project - risk assessment application. I have a trouble to achieve saving on related objects for my application risk record. I am using MultiModelForm to achieve the following.

Django squashmigrations: How to rollback effects of squashmigrations command?
I have squashed migrations and it created a new migration files by squashing all the migrations of the app. Due to some post squashmigrations issue I want to undo the effects of squashmigrations command. The problem is that now migrate command is not working because Django is not able to detect the presence of old migrations file that are squashed into a new migrations file. Example: Let's say all the four migrations from 0001 to 0004 are applied and then I squash them by running the following command. $ ./manage.py squashmigrations myapp 0004 Will squash the following migrations: - 0001_initial - 0002_some_change - 0003_another_change - 0004_undo_something Do you wish to proceed? [yN] y Optimizing... Optimized from 12 operations to 7 operations. Created new squashed migration /home/andrew/Programs/DjangoTest/test/migrations/0001_squashed_0004_undo_something.py You should commit this migration but leave the old ones in place; the new migration will be used for new installs. Once you are sure all instances of the codebase have applied the migrations you squashed, you can delete them. Now if I try to run the following command to rollback to previous state: python manage.py migrate myapp 0004 It throws an error saying CommandError: Cannot find a migration matching'myapp/migrations/0004_undo_something.py' from app 'myapp' -

In datatables, how can we show headers while loading, and then when data loads, show all the datatable?
I am running a django project in which I have a html page to render where I am displaying some data in tabular format using datatables.

But I want the table headers and the filters and search tab that comes with datatables to be displayed while those 2 seconds of loading time, and when the data is ready, complete datatable will be displayed. How can I do that? Thanks in advance. -

Correct way to consume 3rd party API with query in Django + React (Backend + Frontend)
I'm using Django on my backend and React on my frontend. I want to consume the OpenWeatherMap API. For security reasons, I want to keep my API key on the backend. Currently, I have this working on my Django app. When a POST request is made, the Django view renders the information required from OpenWeatherMap. How can the user type the query in React, send the query to to the backend and get the results on the frontend? I have a very hacky way of doing this currently: I POST (using axios) the city that the user enters in React to a REST API that I built in Django. The backend queries the OpenWeatherMap API with the city that the user enters and POSTs the data that it gets from OpenWeatherMaps back to my API. After this, the frontend uses a GET request on my API to show the information to the user. I'm pretty sure this isn't the correct way to do this but I couldn't find any other questions on this, and I'm pretty new to web development. -
Rendering custom html templates in Django
I am not an expert in Django, but this software is written in Django using the rest framework, and I need to make customizations to it: https://github.com/openvinotoolkit/cvat/tree/develop/cvat I need to render a custom html template, and this is what I've done so far. I created a new folder in apps called custom with these files: cvat/apps/custom/templates/custom/<name>.html (there are various html templates in custom with different "names". i.e. a.html, b.html, c.html, etc.) Other files in cvat/apps/custom: cvat/apps/custom/__init_.py cvat/apps/custom/apps.py from django.apps import AppConfig class CustomConfig(AppConfig): name = 'cvat.apps.custom' cvat/apps/custom/urls.py from django.urls import path from . import views urlpatterns = [ path('custom/<str:name>', views.CustomView), ] cvat/apps/custom/views.py from django.shortcuts import render def CustomView(request, name): return render(request, 'custom/'+name+'.html') In addition, I have modified these existing files to add the custom folder that was created in apps: https://github.com/openvinotoolkit/cvat/blob/develop/cvat/urls.py#L27 added path('custom/', include('cvat.apps.custom.urls')),: urlpatterns = [ path('admin/', admin.site.urls), path('custom/', include('cvat.apps.custom.urls')), path('', include('cvat.apps.engine.urls')), path('django-rq/', include('django_rq.urls')), ] https://github.com/openvinotoolkit/cvat/blob/develop/cvat/settings/base.py#L129 INSTALLED_APPS = [ ...

Django Channels: Send message from outside Consumer Class

So that I can send message to client. However, It's not. Can anyone here know what's I missing? Any help is very appreciated. Thanks! -

How use a different language with Django?
Is it possible to customise every error message in Django? I am using a language that does not seem to be supported by Django so the translation method won't work. Also, I prefer to write my own error messages. If I have to manually change everything, is there somewhere I can see all the error messages and where they're used in Django? For example, all the error messages associated with a form or a field, such as unique, min_length, etc. -
