GENERATED ALWAYS AS at MariaDB in Django
I have a column in mariadb called operator_tax_info, with the following structure, CREATE TABLE `operator_tax_info` ( `id` int(11) NOT NULL AUTO_INCREMENT, `created` datetime(6) NOT NULL, `modified` datetime(6) NOT NULL, `visible` tinyint(1) NOT NULL, `operator_id` int(11) DEFAULT NULL, `geolocation` point NOT NULL, `data` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NOT NULL CHECK (json_valid(`data`)), `fiscal_number` varchar(255) GENERATED ALWAYS AS (json_unquote(json_extract(`data`,'$.fiscal_number'))) STORED, PRIMARY KEY (`id`), KEY `operator_tax_info_operator_id_0c173d85_fk_companies_operator_id` (`operator_id`), SPATIAL KEY `operator_tax_info_geolocation_id` (`geolocation`), KEY `fiscal_number` (`fiscal_number`), CONSTRAINT `operator_tax_info_operator_id_0c173d85_fk_companies_operator_id` FOREIGN KEY (`operator_id`) REFERENCES `companies_operator` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=639 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_general_ci as you can see the column fiscal_number is a generated column from data column which is a json field, that column was recently added, to get fiscal_number from the json, and also as backend we use Django 3.2 as our ORM, with the following Model definition: class OperatorTaxInfo(BaseModel, SoftDeletionModel): operator = models.ForeignKey( 'companies.Operator', related_name='operator_tax_info_operator', on_delete=models.DO_NOTHING, null=True) data = JSONField(default=dict) geolocation = geomod.PointField('Geo_localizacion', default=Point(0, 0)) class Meta: db_table = 'operator_tax_info' So my question is there a way to map this column from mariadb to Django, or how to generate this column from Django using migrations and indexes, without losing speed from db, because I have trying using a @property decorator to map and annotate this … -
URL Appending instead of redirecting
When I click the link on my HTML page, instead of redirecting to the clicked url it appends to the current one and displays an error (404). How can I solve this and redirect to the correct url?

Facing an issue to update an existing object in Django 4
I'm working with a Diagnostic tool, I'm trying to update an existing instance of the database, I'm rendering a group of data corresponding to the device which being repaired, I have a second section of my render which shows a group of fields which must be updated by the Diagnosticador, those are the fields which will be updated. For some reason I keep getting orden_de_diagnosticoDiagnostico with this Orden de diagnóstico already exists.. Which is kinda obvious, since I'm looking to update an existing object. Can't find the reason for this to turn the form into invalid. Have tried multiple approaches, get, get_or_create, defining hidden fields emulating another page which already works in a similar way and nothing works. Looking forward to go over this form is invalid error due an object already existing.

Python-Streamlit Security
I'm using Streamlit for a web app. I built a system authenticator with streamlit_authenticator. When users log in, they can view specific data. I made a connection between Streamlit and MySQL. In this database, there are usernames and passwords, as well as specific data for users. Is this approach safe for deployment on the internet? Do you know other ways? For example, I tried with Django, but its difficult to integrate this with Streamlit. -
Django: My context variable with a zip list only works with one for loop. If I want to use the same variable in a different loop it doesn't work
In views.py I have the variable mylist = zip(set1,set2,set3) In templates I do {% for val1, val2, val3 in mylist%} {% endfor %} It works fine. However, if I duplicate the condition it fails. Is it normal? Let's say I have the following: # this is my page some text {% for val1, val2, val3 in mylist %} {{forloop.counter}} {% endfor %} more text {% for val1, val2, val3 in mylist %} {{forloop.counter}} {% endfor %} more text # final text of page The first loop will work, and the second one will be empty. It seems as though I can only use once mylist. I didn't experience this issue with simple lists (as far as I remember) -
Django: default value for select element in django form

How to define public permissions in the base class of django model and generate different codename for each subclass
django-4.2.6+python3.10 This is my base model class： from django.db import models class BaseModel(models.Model): class Meta: abstract = True permissions = [ ("restore", "Restore deleted obj"), ] This is my subclass： class One(BaseModel): name = models.CharField("name for you", max_length=200) class Two(BaseModel): name = models.CharField("name for you", max_length=200) After I executed python manage.py makemigrations and python manage.py migrate It generates such records in the auth_permission table of the database： auth_permission This is not what I want, because their codename is the same, which will lead to confusion. Because I have many such subclasses, all with the same type of permissions, but for different models, I don't want to repeat the definition in each subclass I hope that after running those two commands, it can generate different codename for each model in the database, such as： Generate a permission with the codename restore_one for the one model, and generate a permission with the codename restore_two for the two model. expected I tried to find the answer in the official documentation of django, but I got nothing. Perhaps we can start with the python manage.py makemigrations command. Can anyone tell me how to do it? -
Trouble Using Django Rest Framework 3.0 with Django 3.2 and Python 3.9
I am currently working on an assigmnet that requires working with specific versions of Django, DRF, and Python. Django Rest Framework (DRF) version >3.0 Django version >3.2 Python version >3.9 However, when attepting to use DRF version 3.0, I encountered the following error: django.template.library.InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'rest_framework.templatetags.rest_framework': No module named 'django.core.urlresolvers' I found that upgrading DRF to a version beyond 3.0 resolves this issue. However, the assignment specifically mandates using DRF 3.0. Could you please provide guidance or suggestions on how to address this error while ensuring compliance with DRF 3.0? Any help or insights would be greatly appreciated. Thank you! -
Code 1011 in django website Websockets connection
I have been working on a django chatting application (https://aniconnect.org) which uses daphne (django-channels) for the websocket functionality which allows users to chat with each other.

How to pass optional parameters to a view in Django?
I have a view that takes two optional keyword arguments: team and year_month def monthly_data_list(request, year_month:str=None, team=None): From the template, I want to call different combinations with either one of these 2 parameters, or both. Django docs gives this example of implementing this: path('monthly/list/', views.monthly_data_list, {'team':None, 'year_month'=None },name='monthly-data-list'), However, calling this URL from the template with one or both arguments gives me a NoReverseMatch error: hx-get="{% url 'drivers:monthly-data-list' team=None year_month=current_year_month %}" I found a workaround suggested here, which is to define paths for all combinations of parameters. This works with 2 parameters, but gets complicated on more. How do you correctly implement multiple optional parameters? -

Export enums with drf-yasg to Swagger: Works in responses serializers but not in query_serializer

Where to place raw custom SQL queries in Django?

I understand that the functionality demonstrated in my code can be easily achieved using the Django ORM; this is just an illustration. Should I concentrate all query logic within the serializers.py file, or would it be preferable to create a separate file for this purpose? Could you guide me or provide a resource that explains how to organize this? Here what is ChatGPT saying about this: *"When using raw SQL queries in Django, organizing the code is crucial for maintainability and clarity. It's recommended to separate concerns and maintain a clean structure. Consider these approaches: Services/Managers: Create separate modules like services.py or managers.py to contain functions that handle raw SQL queries. These modules encapsulate … -
