Validation of the serial number against the mask in Django rest
There are two tables - equipment type and equipment, the type has a line with a serial number mask, the equipment has a line with a serial number. When creating new equipment, validation must go through, that is, the string with the serial number is compared with each mask of the equipment type, and if a match is found, the equipment is tied to the type, the question is, how is it better to implement this on the django rest framework? The check is carried out according to the principle: N is a number from 0 to 9; A is a capital letter of the Latin alphabet; a is a lowercase letter of the Latin alphabet; X is a capital letter of the Latin alphabet or a number from 0 to 9; Z is a character from the list: “-“, “_”, “@” That is, if the equipment has a serial number of 0QWER9@123, it corresponds to a mask with characters like NAAAAXZXXX models.py from django.db import models from django.core.validators import MinLengthValidator from django.core.validators import RegexValidator class Type_Of_Equipment(models.Model): name = models.CharField(verbose_name='Тип оборудования', max_length=64, blank=True, default='Без названия') sn_mask = models.CharField(verbose_name='Маска серийного номера', blank=False, max_length=10, validators=[MinLengthValidator(10), RegexValidator(regex=r'^[NAaXZ]+$', message='Использованы недопустимые символы')]) class Equipment(models.Model): code … -
How can I submit Django forms without losing previously rendered HTML?
I am new to Django framework. I am trying to create a mini-project where my UI will have 3 html forms. The intended workflow is that I will submit a text in Input String field. Then I will submit some substrings of the above submitted string and increase the score. The problem I am having is when I submit the substring my page reloads and it resets the previously rendered html. Hence, I lose my actual string for which I am submitting substrings. The html code for Forms <div style="padding: 20px;"> <h1>Words Starting with consonants</h1> <form id="form2" action="consonant_submit/" method="post"> {% csrf_token %} <label for="Stuart">Stuart Text:</label> <input type="text" id="stuart" name="stuart"> <br> <label for="2">Stuart Score:</label> <input type="text" id="score1" name="score1"> <br> <input type="submit" value="Submit stuart"> </form> </div> <div style="padding: 20px;"> <h1>Words Starting with consonants</h1> <form id="form3" action="vowel_submit/" method="post"> {% csrf_token %} <label for="kevin">Kevin Text:</label> <input type="text" id="kevin" name="kevin"> <br> <label for="2">Kevin Score:</label> <input type="text" id="score2" name="score2"> <br> <input type="submit" value="Submit kevin"> </form> </div> The consonant_submit & are django view functions.

python - How to update multiple dictionary key-value without using for loop
I have a list of dictionaries with the same keys but different values. Example: [{ Price = 100; Quantity = 3; }, { Price = 200; Quantity = 5; }] Is there a way to update the value of a particular key in all dictionaries in one go without using for loop? That is, is there a way to make Quantity=0 for all dictionaries in the list in one go? I am looking for performance since I have a huge list of dictionaries, and I'm under the assumption that there may be a faster way to do this than using a for loop. I have. gone through multiple questions on stack overflow but did not get any satisfactory response. -
send selected date to django using htmx & pickadate.js
I use the pickadate.js widget, to select a date. The selected date should be sent to django do query availability. pickadate.js creates a hidden input field with name="date_submit". I use jQuery to add some htmx attributes to listen on the change event of that element. That works so far and the hidden input element has all the necessary hx-attributes assigned to it. I debugged the events with htmx.logAll();. the 'change' event is fired on the element. However, the hx-attributes on the hidden input field don't have any effect and no requests are made to the django backend. The code is part of a form, placed in a modal. rendered hidden input field: <input type="hidden" name="date_submit" value="2023-05-26" hx-trigger="change" hx-get="/" hx-target="#test"> Date Formfield: <div class="form-floating"> {% render_field reservation_form.date class="datepicker form-control mb-3" %} <label for="{{ reservation_form.date.id_for_label }}">Event Date</label> </div> Script: <script> htmx.logAll(); var $input = $('.datepicker').pickadate({ format: 'yyyy-mm-dd', formatSubmit: 'yyyy-mm-dd', min: 0, max: 90, disable: {{ blocked_dates }}, firstDay: 1, onOpen: function() { // Get the hidden input field var hiddenInput = $(this.$node).siblings('[name="date_submit"]'); // Add HTMX attributes to the hidden input field hiddenInput.attr('hx-trigger', 'change'); hiddenInput.attr('hx-get', "{% url 'home' %}"); hiddenInput.attr('hx-target', '#test'); } }); $input.on('change', function() var hiddenInput = $(this).siblings('[name="date_submit"]'); hiddenInput.val($(this).val()); htmx.trigger(hiddenInput[0], 'change'); }); … -

My goal is to achieve a reliable and scalable deployment, optimizing performance and minimizing costs. Specifically, I have the following questions: What is the recommended approach for deploying an Angular-Django app on Hetzner Cloud? Are there any specific tools or frameworks that work well in this setup? How can I leverage Docker for containerizing my application and managing its dependencies? Are there any best practices or considerations I should keep in mind? What is the suggested database setup for Django on Hetzner Cloud? Should I use … -
Django returns corrupted zip file

how to access a django sqlite3 database from command line?
I'm using an sqlite3 database for a django app, and it works correctly. I can print the version used with this code i wrote inside a view: # views.py import sqlite3 def my_view(..): connection = sqlite3.connect('C:/path/to/db.sqlite3') cursor = connection.cursor() cursor.execute('SELECT sqlite_version();') result = cursor.fetchone() sqlite_version = result[0] print("SQLite version:", sqlite_version) ... But if i run from command line python manage.py dbshell i get CommandError: You appear not to have the 'sqlite3' program installed or on your path. There are similar questions but the answers for example suggests to download sqlite3 which i don't think it makes sense because I can see that I already have a version installed Using: Django 4.2, Python 3.10.4, sqlite3 3.37.2.

Django: Save inline form before run action
I'm using a django-inline-actions package for let end-users run actions in admin inlines. But it's no matter what exactly using for action button, i can implement it by hand (like this, for example), behavior will still the same. This look as: As provided by the django engine, the user does things like: Fill inline Click Save and continue button Click action button and he repeating it again and again, becouse users use action buttons very often. Is there any possibility for omit step 2? I think, it can be javascript hook, which capture click event, save inline data with ajax, and then run action. But i have no idea how implement it. May be there is another way to do it? -
