python django asyncua subscription synchronous

Is it possible to store a queue-like structure in Django database?
This might be a stupid question, but I'm new to databases and I could't find an answer anywhere. Is it possible to somehow store a FIFO queue in django? Some equivalent of python's collections.deque? Let's say I hypothetically have a model AverageRate, which stores a queue of up to 24 numbers and an average value of those numbers: (sum(numbers) / len (numbers)). class AverageRate: last_24_numbers = # FIFO queue up to 24 elements long average_value = # average value of last_24_numbers Every hour a function adds a new number to last_24_numbers and calculates average value. If the queue reaches 24 elements, then to append a new element to the end of the queue, it must pop the oldest element from the beginning of the queue. Honestly the only solution I came up with was to possibly convert the queue to string and store it in CharField, and then convert it back every time I need to use it. But I dunno... it just feels like not the best idea. I would obviously want to use the most efficient solution. -

django AdminEmailHandler send sensitive information when include_html is False

Why does django only allows access to the widget attributes when it renders a field into a form
I have a question about Django template rendering. Right now I use it to build a full-stack app, so the issue is that when I try to override a default form rendering behavior, I see that despite I can possibly overwrite default html without boilerplate, it is becoming harder as I dive deeper. Let's take a look on the excerpt from table.html which renders form as table. ... {{ field }} {% if field.help_text %} <br> <span class="helptext"{% if field.auto_id %} id="{{ field.auto_id }}_helptext"{% endif %}>{{ field.help_text|safe }}</span> ... Here we see that every form Field will render like <label> ~<input> <span> (help_text) But what if we want to overwrite default Field(e.g. ImageField) rendering behaviour to produce html portion like the below code to be able to add a preview avatar before the <input>-<help text> combination. <div> <img>(preview) <div> <input> <span>{{ field.help_text|safe }}</span> </div> </div> We can't just write custom html for our field, like django/forms/widgets/text.html, because it only has Widget in the context. So without boilerplate it is straightforward to overwrite how <input> tag is rendered using custom html files, but it is not straightforward how to make custom <label> and help_text rendering on per-field-class basis. Seems like we … -

Friendly duration picker ready to be used as a form widget in a Django application
I need to let a user select a duration in a form field of a Django application. I'm already using bootstrap (namely django-bootstrap-datepicker-plus) to select other fields such as Date, Time and DateTime. But duration is something lightly different. I'm currently having a simple integer field where the user is asked to input the duration value in minutes. But once the duration last for some hours, e.g. 07h24, the user has to compute to how many minutes it corresponds before entering the right value. This is error prone. On the opposite, if I ask the user to input values in hours, 7h20 would become 7.3333. This is also error prone and it's not precise in that case. That's why I'm searching for a true duration picker. Using two DateTime pickers and computing the timedelta is also not an option for the lack of user-friendliness. Hence my question: does a friendly duration picker exists inside bootstrap for Django and if not, does something other exist? I guess I don't have to reinvent the wheel, but I wasn't able to figure out something which integrates well with Django 4. Ideally, jQuery should also be avoided. My current research led me to these … -

Custom user model vs. additional model
Due to lack of knowledge, when faced with the need to store additional information about users, I created additional UserInfo model and referenced it by foreign key to the standard User model. I have since learned two things: It is recommended to have a custom user model. It is tricky to switch mid-project (this being the best way so far as far as I understand). I would like to understand: If the fields in UserInfo are not used for authentication, is there any reason to merge those into the user model? What do I stand to gain by taking the time to abandon my current approach and switch to a custom user model? -

Can we use django-distill to host a Django website in Github pages?
I'm exploring options for hosting a Django website on GitHub Pages, and I came across the django-distill package. I'm wondering if it's feasible to use django-distill for hosting a Django website on GitHub Pages. Here are some specific points I'm curious about: *Has anyone successfully used django-distill to deploy a Django website on GitHub Pages? *Are there any specific configurations or steps that need to be taken to make it work with GitHub Pages? I appreciate any insights or experiences you can share regarding using django-distill or any other approach for deploying a Django site on GitHub Pages. I attempted to use django-distill to deploy a Django website on GitHub Pages. My approach involved configuring django-distill and following the standard steps for deploying a Django project. However, despite my efforts, I encountered challenges, and the deployment did not work as expected. Link: https://django-distill.com/ -
