How to show validation errors in template using CreateView Django
I am using an extended User model and a generic CreateView. class SignUp(CreateView): form_class = forms.SignUpForm success_url = '/accounts/login/' template_name = 'accounts/signup.html' How do I access the form validation errors in my template? They must be there because when I do {{ form.as_p }} the errors show up. I have tried {{ form.errors }} and {{ field.errors }} but there is nothing in them. Is there a simple tag I can call in my template to show the errors? Thanks. -
Add pre-filled resizable text boxes (forms.Textarea) to the django form
I need to create a form, where text-boxes would be resizable (so Textarea widget has to be used) and pre-filled. I tried to pre-fill them through .initial and value attribute. Problem: If Textarea widget is used: text boxes are resizable but no value is shown forms.CharField(label='', widget=forms.Textarea(attrs={"rows": 1, "cols": 50, "value":column_data}) self.fields[f'inserted_value_{column_name}'].initial=column_data If TextInput widget is used: text boxes are not resizable but value is shown forms.CharField(label='', widget=forms.TextInput(attrs={"rows": 1, "cols": 50, "value":column_data}) There amount of form elements (always the same Text-box) is going to be dynamic, so they are created in def __init__ and should also get their value there. Theoretically value attribute should work, but it returns me empty text-boxes. -
Changing form action based on select option value
I am trying to change the form url_for action based on the selected option: Django template: <form name="List_select" id="List_select" method ="POST"> <div class="modal-body"> <label>Move Item</label> <select class="form-control" id="Lists"> <option value="{{ url_for('complete_item', titleID = item.id) }}">Move to Done</option> <option value="{{ url_for('doing_item', titleID = item.id) }}">Move to Doing</option> <option value="{{ url_for('revert_item', titleID = item.id) }}">Move to To Do</option> </select> <input class="btn btn-primary" type="submit" value="Move"> </div> JQuery $(function() { $(".Lists").change(function(){ value = $(this).val() $('.List_select').attr('action', value) }) }); When I try select an option and press the Move button, however I get: Method Not Allowed The method is not allowed for the requested URL. -
Quick fix: Flipping the side on which DMs are displayed on a social media platform
Within the DM function on my social media platform I would like the received messages to appear on the left hand side and the sent messages to appear on the right hand side. Currently it is the other way round. (Sent messages (light pink) = #D7A5EB, received messages (dark pink) = #CC64C3) Ì have been trial-and-erroring this for a while now, but it simply refuses to allow sent messages (I.e. the ones that the currently logged-in user sent) on the right hand side. thread.html: {% extends 'landing/base.html' %} {% load crispy_forms_tags %} {% block content %} <div class="container"> <div class="row"> <div class="card col-md-12 mt-5 p-3 shadow-sm"> {% if thread.receiver == request.user %} <h5><a href="{% url 'profile' thread.user.profile.pk %}"><img class="rounded-circle post-img" height="50" width="50" src="{{ thread.user.profile.picture.url }}" /></a> @{{ thread.user }}</h5> {% else %} <h5>@{{ thread.receiver }}</h5> {% endif %} </div> </div> {% if message_list.all.count == 0 %} <div class="row my-5"> <div class="col-md-12"> <p class="empty-text">No messages yet.</p> </div> </div> {% endif %} {% for message in message_list %} <div class="row"> {% if message.sender_user == request.user %} <div class="col-md-12 my-1"> {% if message.image %} <div class="message-sender-container ms-auto"> <img src="{{ message.image.url }}" class="message-image" /> </div> {% endif %} <div class="sent-message my-3"> <p>{{ message.body }}</p> … -

Connecting an internet-facing Django web app (served with Gunicorn) with a non-internet-facing local application to be used by the Django web app
Use case of the internal app: take in a list of words (200-300 words), perform some analysis on them and return large tuples of data, anywhere from 5-10 tuples per word. The Django application will block waiting for the results of the internal app to serve the webpages that needs the word analyses. The reason I want to separate them is because the internal app uses a lot of memory, and integrating the word-analysis (i.e. the task of the internal app) into the Django app will cause high memory usage because of gunicorn forking multiple workers. The internal app uses about 1GB of memory once loaded, but is not compute-intense. Now, assuming I want to host the Django web app and the internal app on the same server, what comes to my mind is to use a flask application for the internal app, and put it behind gunicorn. So two questions: Is there a better way to accomplish this? Is using gunicorn the right way to go for the internal app? -

Django Redirects + FeinCMS - URL variable
I am using an older server with Python 2.7 and Django 1.11.7 with FeinCMS as the CMS. If I wanted to redirect any incoming URL from a request that had mixed casing to the proper URL in all lowercase letters, how would I go about doing that? Is there a way to edit the incoming request and, if the page is matched but it's detected not to be a match to the lowercase URL, it will do a redirect to the page? I have the original function below and one that I edited and made enough progress to get the proper page to show up, but the URL in the address bar still has the mixed casing. Any help would be greatly appreciated.
