How do we make a htmx response trigger a form reset?
I am creating a very basic Django messaging application, and would like to use htmx to send and render messages. I am able to post, save the message, and render the partial message without issue. However, I am running into a weird problem where my form textarea is not being reset. So, I would send a message, and after the swap is inserted, my old message would still be in the textarea. This isn't very ideal! I tried to manually clear the textarea by adding an onclick event like so: Html <div id="new-message-div"></div> <form id="message-form" class="chat-form rounded-pill bg-dark" data-emoji-form="" hx-post="{% url "chat:create-message" object.pk %}" hx-target="#new-message-div"> ... {{ message_form }} ... <button class="btn btn-icon btn-primary rounded-circle ms-5" type="submit" onclick="submitForm()"> </button> </form> Script (https://stackoverflow.com/a/14589251/12758446) <script> function submitForm() { var message_form = document.getElementById('message-form'); message_form.submit(); // Submit the form message_form.reset(); // Reset all form data return false; // Prevent page refresh } </script> Despite having the message_form.submit() in the submitForm(), my form is not being submitted, but the textarea is getting reset. Question: How would I go about getting my textarea reset after successfully sending and rendering a message?

Django login + pasword
[enter image description here][1] [1]: https://i.stack.imgur.com/ECii0.jpg Всем привет уважаемые коллеги! Сразу хочу сказать что, я недавно в IT и только учусь, прошу не употреблять профессиональные выражения, в решении данного вопроса, благодарен заранее! Я развернул проект Django, создал свой проект, хочу свой проект видоизменить, понимаю что основные файлы django лучше не изменять, по этому в корень своего проекта скинул копии файлов: login.html, base.html, base_site.html а так же в папку проекта скопировал файлы стилей: login.css и base.css. Связываю HTML файлы с CSS стилями, но при запуске своего проекта, все равно загружаются CSS файлы django. Подскажите где я ошибся и что делаю не так? Моя задача изменить стандартное отображение ввода окна login + password под свое представление ! -

Django NoReverseMatch error - urls.py path appears to match
In a Django application I am building as a project for an online course, I am expecting a link in one template (entry.html) to direct to a path ("edit") in urls.py with a variable in the url. This should initiate a function called edit in views.py and render the template edit.html. I am getting a NoReverseMatch error ("Reverse for 'edit' with no arguments not found. 1 pattern(s) tried: ['(?P<entry>[^/]+)/edit$']") after clicking the link in entry.html. If I view page source while on entry.html in the development server, I can see the url matches that in urls.py but I still get this error. In the example below, "maggie" is the value for entryTitle I'm trying to pass. entry.html: {% block title %} {{ entryTitle }} {% endblock %} {% block body %} {{ entry|safe }} <button> <a href="{% url 'edit' entry=entryTitle %}">Edit Entry</a> </button> {% endblock %} urls.py (last path listed is edit) from django.urls import path from . import views urlpatterns = [ path("", views.index, name="index"), path("wiki/<str:entry>", views.entry, name="entry"), path("search", views.search, name="search"), path("new", views.new_page, name="new"), path("wiki/<str:entry>/edit", views.edit, name="edit") ] edit function in views.py from django.http import HttpResponseRedirect from django.urls import reverse class EditPageForm(forms.Form): content = forms.CharField( widget=forms.Textarea(), label="Edit Content:") def … -
how to pass a function in python mock side effect
I want to achieve the following: mocked.side_effect = somefunction and when mocked() gets called I want somefunction() to get executed however, right now when mocked() gets called only the name of the function is returned and not the callable. Note: I don't want to just do mocked.side_effect = somefunction() because that will call the function first and then result in a value. I would like the function to be called when mocked is called -

How do I resolve database migration error due to changed migration filename?
I'm still pretty new to Python as well as Django so I have a situation I'm not sure how to resolve. Main issue is that on deploy of my code to dev, deployment fails, to stage or prod, it passes. I worked on an issue where I had to drop some columns in a table in our app. After making the changes, I deployed to dev and asked for a code review. In code review, it was suggested I change the name of the migration file to something more descriptive rather than just leaving it 0018_auto_. I made that change and deployed to dev and stage. Dev failed (when I expected it to succeed) because the new name was seen and django tried to drop columns that no longer exist. In stage, the name was never changed and the columns were dropped for the first time using that new name of the file. So stage deploys just fine. How do I resolve this error on dev so it recognizes this migration already took place? Thanks! -

Django - Show Timeslots by Availability

How to POST an entity specifiying an integer foreign key in django rest framework

Override Djange ImageField extension validation
Understand I can add a validator to Django's ImageField validators to restrict file extension types like below. But in terms of the error messages which are displayed via upload on Admin -- I'm still seeing the standard file type list (via PIL allowed types), if I upload a non-image type. If I upload an image type which is not in my custom allowed_extensions below, I see my custom message. How can I override Django's default ImageField handling, and show my custom error message no matter what type of file is uploaded (e.g. when any file other than .png is uploaded per below example)? class MM(models.Model): file_extension_validator = FileExtensionValidator( allowed_extensions=['png'], message='File extension not allowed. Allowed extensions include .png' ) image = models.ImageField( help_text='Upload images only (.png).', validators=[file_extension_validator], max_length=255, blank=False, null=False ) -
