The .mp3 file that generated by AWS Polly does not run at all
I have made a rest API using Django Rest Framework. I gonna convert a sentence to speech using AWS Polly and tried to run it in my local environment. When I run the endpoint, a .mp3 file has generated in the root folder. The result message says "save success!". But the file does not work as well the file contains the size. I am hearing nothing.

How to restart a Django project after terminal shut down
I've been learning Django from a Youtube Tutorial. I have a good basis in python, but have never worked with this. we have been starting an app and ran a server with "python3 manage.py runserver" command. Everything was working fine. problem is that terminal shut down, and i have no idea how to just restart the server. I go to the same directory as we did the first time, activate my virtual environment, but when I type the runserver command, i face this error: ModuleNotFoundError: No module named 'main' I have no clue how to solve this. Any advice ? Thanks ! -
Django - 'AssertionError: .accepted_renderer not set on Response' on DRF endpoint with Middleware
So I wanted to create Middleware to add authentication to every endpoint automatically. It seems to be creating issues for Django Rest Framework endpoints using @api_view decorator.

The best way to catch IntegrityError on admin page?

Django: UniqueConstraint validator does work neither for model nor for intermediate model
My project is basically a platform, where one can post one's recipes with tags (for example, breakfast or dinner) and ingredients (carrot, milk, etc.). I would want to implement unique constraint for recipe, so that user could not create one with, say, two identical tags or ingredients. So, I have decided to use django UniqueConstraint validator for that, but even migrations did not apply, django says: "No changed were detected". from django.db import models from django.contrib.auth import get_user_model from django.core.validators import MinValueValidator, MaxValueValidator User = get_user_model() class Recipe(models.Model): author = models.ForeignKey( User, on_delete=models.CASCADE, related_name='recipes', verbose_name='автор', ) name = models.CharField( max_length=200, verbose_name='имя', ) image = models.ImageField( max_length=4096, upload_to='images/%Y-%m-%d', verbose_name='фото', ) text = models.TextField(verbose_name='описание') ingredients = models.ManyToManyField( 'Ingredient', through='RecipeIngredient', verbose_name='ингредиет', ) tags = models.ManyToManyField( 'Tag', through='RecipeTag', verbose_name='тэг', ) cooking_time = models.IntegerField( default=60, validators=( MinValueValidator(1), MaxValueValidator(44640) ), verbose_name='время приготовления (в минутах)', ) creation_date = models.DateTimeField( auto_now=True, verbose_name='дата создания рецепта', ) class Meta: verbose_name = 'рецепт' verbose_name_plural = 'рецепты' def __str__(self): return f'Рецепт - id: {self.id}, имя: {self.name}.' class Tag(models.Model): name = models.CharField( max_length=256, verbose_name='имя', ) color = models.CharField( max_length=64, verbose_name='цвет', ) slug = models.SlugField( max_length=64, verbose_name='слаг', ) class Meta: verbose_name = 'тэг' verbose_name_plural = 'тэги' def __str__(self): return f'Тэг - id: {self.id}, имя: …
