How to Avoid Duplicate Validation When Creating Django Model Instances Manually and via Forms?
I’m new to Django and I need some help with model validation. Here’s what I’m trying to figure out: When I create new instances using forms, I know that calling is_valid on the form automatically runs the full_clean method for validation. After that, I just call save on the form. But when I create new instances manually, I need to call full_clean manually before calling save. I saw online that some people suggest overriding the save method in the model to ensure custom validation always runs, like this: def save(self, *args, **kwargs): self.full_clean() super().save(*args, **kwargs) This works fine when I’m creating instances manually, but it seems to call full_clean twice when I use forms (once during is_valid and once during save). This feels redundant and probably not efficient. My Question: What’s the best way to make sure my custom validation runs in Django models both when creating instances manually and via forms, without calling full_clean twice? Any advice or best practices would be really appreciated! Thanks a lot! -

Why is my AWS EC2 instance Supervisor failing?
I'm deploying a Django API I've named "ScientistBirthYear" to AWS EC2 following these instructions, including using the gunicorn.conf code, but modifying it to account for my virtual environment's name, project name, and X.wsgi:application from my project.

How to Properly Handle Character Encoding in Django Database Dump?
I'm working on a Django project and I've encountered a character encoding issue when dumping my sqlite3 database to a JSON file. The database contains special characters such as accented letters (e.g., "França", "Bélgica"), but when I dump the data, these characters are not displayed correctly. Im trying to migrate the data from sqlite3 to MySQL. Currently, my dump file contains incorrectly encoded characters like: "França" instead of "França" "Bélgica" instead of "Bélgica" "EslovÛnia" instead of "Eslovênia" "Ge¾rgia" instead of "Geórgia" Could someone please guide me on how to ensure the Django dumpdata command creates a JSON file with the correct UTF-8 encoding from the start? When i execute the commando: python manage.py dumpdata > db_data.json, my JSON is shown as "UTF-16 LE" Here are the steps I've taken so far: I've ensured my database (MySQL) is set to UTF-8 encoding. I've tried using Python scripts to manually fix the encoding issues after dumping the data, but the problem persists. My goal is to have the JSON dump file correctly display all characters. -
Problems with changing the status from pending to rejected/approved

Prevent duplicates when filtering on prefetch_related
I have two models: Seller and Product. Each product has a foreignKey to a seller. So each product only has one seller, but a seller can be related to many products. This is the ForeignKey in my Product-Class: seller = models.ForeignKey( Seller, on_delete=SET_NULL, null=True, related_name="products", ) Now I try to query all Sellers and have the related products for each seller with them. sellers = ( Seller.objects.filter( ..doing some filtering ).prefetch_related("products").filter(products__branch=current_branch) ) By doing this, my sellers has multiple entries for many sellers as I am filtering on the prefetche_related products resulting in a join inside the database-query. What would be the best way to end up with a List of Sellers, each of them having their list of products with them? Without duplicates. I still need to filter on the products as I don't want all the products to be queried. -
Django - get value of a form textinput on onchange event
I am using this to get the ID and the value of a select item in a form in django with the onchange event: class forms_bdc(forms.ModelForm): [...] bdc_description_1 = forms.ModelChoiceField( widget=forms.Select(attrs={'id': 'editable-select-2','onchange': 'populate_selected_product(this.id,this.value)'}),empty_label=None ) I am trying to do the same with a TextInput widget.

ValueError('JSON string "{0}" is not valid json. {1}'.format(json_str, err)) ValueError: JSON string "{" is not valid json [closed]
I have a serviceAccountKey.json file with the following code { "type": "service_account", "project_id": "...", "private_key_id": "...", "private_key": "-----BEGIN PRIVATE KEY-----...", "client_email": "...", "client_id": "...", "auth_uri": "...", "token_uri": "...", "auth_provider_x509_cert_url": "...", "client_x509_cert_url": "...", "universe_domain": "..." } All this information is, of course, filled in when I downloaded the file from firebase console for my project. I keep getting this error message. \ raise ValueError('JSON string "{0}" is not valid json. {1}'.format(json_str, err)) ValueError: JSON string "{" is not valid json. Expecting property name enclosed in double quotes: line 1 column 2 (char 1) The error seems to be coming from the line json_data = json.loads(json_str) from the init.py file in firebase admin in the "lib" sub directory of my virtual environment. I am using python 3.6. I looked at different solutions online, but none of them answered my question. Thanks for any help. -
Django test database configuration for unittest
I am running unittest with coverage command but having trouble with test database interaction. Here is my code snippet. from django.test import TestCase from myapp.models import Animal class AnimalTestCase(TestCase): def setUp(self): Animal.objects.create(name="lion", sound="roar") Animal.objects.create(name="cat", sound="meow") def test_animals_can_speak(self): """Animals that can speak are correctly identified""" all_animals = Animal.objects.all() print(all_animals) If I run this code and try to print all animals in the database, it only prints the animals in the real database and not print for Animals like lion and cat. I think this might be related to the database configuration I tried to use this configuration in the settings.py. from django.test import override_settings @override_settings(DATABASES={ "default": { "ENGINE": "django.db.backends.sqlite3", "NAME": "db.sqlite3", "TEST": { "ENGINE": "django.db.backends.sqlite3", "NAME": "test.sqlite3", } }, "read_replica": { "ENGINE": "django.db.backends.sqlite3", "NAME": "db.sqlite3", "TEST": { "ENGINE": "django.db.backends.sqlite3", "NAME": "test.sqlite3", } }, }) but this is still not working. My expectation is to interact with test database so based on my code snippet, I want to print lion and cat.
