How can I import a python file coded by myself and then see what it does on a django website?
I am currently working on my website, which is a translator which you input a phrase and it gets translated into an invented language. Here's the code of the translator function: def translator(phrase): translation = "" for letter in phrase: if letter.lower() in "a": if letter.isupper: translation = translation + "U" else: translation = translation + "u" elif letter.lower() in "t": if letter.isupper: translation = translation + "A" else: translation = translation + "a" elif letter.lower() in "c": if letter.isupper: translation = translation + "G" else: translation = translation + "g" elif letter.lower() in "g": if letter.isupper: translation = translation + "C" else: translation = translation + "c" return translation However, I am stuck in showing this funcion in my web, here's the code in views.py: from .translate import translator def translator_view(request): return render(request,'main/translator.html') def translated_view(request): text = request.GET.get('text') print('text:', text) translate = translator dt = translator.detect(text) tr = translated.text context = { 'translated': tr } return render(request, context, 'main/translated.html') Here's the template where you introduce the text: <form action="{% url 'translated' %}" method= "get"> <div class="form-group"> <center><h2 class = "display-3">TRANSLATE YOUR DNA CHAIN</h2></center> <br> <br> <textarea class="form-control" id="exampleFormControlTextarea1" rows="6"></textarea> <br> <button type='Submit' class= "btn btn-primary btn-lg btn-block">Translate</button> </div> </form> … -
Login with Django and Ajax does nothing
Here is my form: <form action="#" method="post"> {% csrf_token %} <div class="form-group"> <label for="exampleInputEmail1">Enter Username:</label> <input type="text" class="form-control" id="username" name="username" placeholder="Username" autocomplete="off"> </div> <div class="form-group"> <label for="exampleInputEmail1">Enter Password:</label> <input type="password" class="form-control" id="password" name="password" placeholder="Password" autocomplete="off"> </div> <button class="btn btn-primary" id = 'login_button'>Login</button> </form> And the script: <script src="{% static 'js/jquery-3.5.1.min.js' %}"></script> <script> var login_button = $('#login_button') login_button.click(function(){ var username = $('#username').val() var password = $('#password').val() $.ajax({ url: '{% url 'td_app:do_login' %}', type: 'get', data: { 'username': username, 'password': password }, dataType: 'json', success: function (data){ console.log(data.result) } }).done(function (){ console.log(data.result) }) }) </script> In my views.py: def do_login(request): username = request.GET.get('username') password = request.GET.get('password') user = authenticate(username=username, password=password) data = {} if user: if user.is_active: login(request, user) data['result'] = 'success' return HttpResponseRedirect(reverse('td_app:index')) else: data['result'] = 'failed' return JsonResponse(data) And finally my urls.py: url(r'^api/do_login/$', views.do_login, name='do_login') However all of these doesn't work and it doesn't even give me any errors. It just completely refreshes the whole page and does nothing. I tried putting alerts but on the success and done section but it doesn't show it up. Any thoughts/advices? Thanks a lot! -
How to download videos on Django (youtube_dl)
I am making a website for downloading videos from YouTube and not only. For this I use the youtube_dl library. When the button is clicked, I redirect to the file link. I also made a site about programs for Windows, and when I redirect to a file link, it was downloaded. It doesn't work with video, the video just opens in the browser. So this is how to download videos? views.py: from django.shortcuts import render, redirect from .models import Video import youtube_dl import uuid def index (request): last_video = Video.objects.last () current_video = Video.objects.get (pk = last_video.pk) return render (request, 'main / index.html', {'current_video': current_video}) def video_loader(request, video_id): video_url = request.GET.get('url', '') filename = str(uuid.uuid4()) ydl_opts = { 'format': 'bestvideo', 'outtmpl': f'media/videos/{filename}.%(ext)s' } if video_url: with youtube_dl.YoutubeDL(ydl_opts) as ydl: ydl.download([video_url]) Video.objects.create(name = filename, url = video_url, file = f'videos/{filename}.mp4') else: pass current_video = Video.objects.get(pk=video_id) return redirect(current_video.file.url) Html form: <form class="banner__form" id="banner__form" method="POST" action="{% url 'video_loader' current_video.pk%}"> {% csrf_token %} <input class="banner__input" id="banner__input" type="text" placeholder="Enter link" autocomplete="off" name='url' maxlength="100"> <button type="submit" class="fas fa-search fa-2x banner__btn" id="banner__btn"></button> </form> If you still need something, I will throw it off. -
Splitting django project in two big modules and getting import problems
I want to start a new enterprise project which will be very large and will have a thorough business logic. I want to split it into two "sub-projects", one with the models, api and business logic (called "business"), and the other with the views for the web app (called "webapp"). The idea of separating the web app (views) from the models, api and business logic is because I want these 3 lasts to be the service for both web app and mobile too. The layout looks like this: project/ + business/ | + __init__.py | + rest_urls.py | + business_app_1/ | | + __init__.py | | + controllers.py | | + models.py | | + serializers.py | + business_app_2/ | | + __init__.py | | + controllers.py | | + models.py | | + serializers.py + project/ #this one is just the main configuration django app | + __init__.py | + settings.py | + urls.py | + wsgi.py + webapp/ | + __init__.py | + urls.py | + view_app_1/ | | + views.py | + view_app_2/ | | + views.py | + view_app_n/ | | + views.py I just ran a test because I never made a complex layout like … -
django-summernote codemirror theme setting
I would like to to set custom theme for 'codemirror' mechanism at django-summernote. In Readme.md of django-summernote it says (https://github.com/summernote/django-summernote/blame/master/README.md#L222): You have to include theme file in 'css' or 'css_for_inplace' before using it. I found codemirror themes there: https://codemirror.net/demo/theme.html https://github.com/codemirror/CodeMirror/tree/master/theme in settings.py I've added: SUMMERNOTE_CONFIG = { 'codemirror': { 'mode': 'htmlmixed', 'lineNumbers': 'true', 'theme': 'monokai', } } Question: where to put css files - somewhere in site-packages of django-summernote or inside my django app? If in my app - where in static/ folder. I've tried both above options but it didn't worked. How to do it properly? -
Would it be possible to filter results based on an aggregated child field using django-filter?
I have invoices with items in them. Item's have prices. Now I wish to sum the items and based on the sums, filter the invoices. Here are the models class Invoice(models.Model): title = models.CharField(max_length = 150) reciept_image = models.ImageField(upload_to='invoice_receipts/%Y/%m/%d', null = True, blank = True) date = models.DateTimeField(default=datetime.now) class Item(models.Model): invoice_id = models.ForeignKey(Invoice, on_delete=models.PROTECT) item_name = models.CharField(max_length = 150) amount = models.DecimalField(max_digits=9999, decimal_places=2) The Serializers are class InvoiceSerializer(serializers.ModelSerializer): item_set = ItemSerializer(many = True, read_only = True) class Meta: model = Invoice fields = ['id', 'title', 'reciept_image', 'date', 'item_set'] class ItemSerializer(serializers.ModelSerializer): class Meta: model = Item fields = ['id', 'invoice_id', 'item_name', 'amount'] I simply cannot seem to wrap my head around this.

Connecting Django 3.1 to MongoDB
I am working with Django 3.1 edition. As a Database, my choice is to go with any NoSQL database like MongoDB. I have tried two ways to connect MongoDB with Django 3.1. First One is using Djongo and the Second one is using Mongo Engine. But both the cases, I am unable to work with Django 3.1. In the case of Django, it's not supporting Django 3.1 but it switching me to Django 3.0.5, and in the case of mongo engine it's not supporting Django 3.1.

How to implement two different types of users with extended attributes in Django?
I am using python 3.8.3 and Django 3.0.8 I am building a project that allows students and teachers to login to it. Hence I have two different kinds of users. Also these two users have extended attributes and methods apart from the one that Django provides implicitly to its user model, like department, organisation, etc. How can I implement them? Most of the articles I come across are either very old and for outdated versions of Django and python or they don't combine my required functionality? How can I extend my user model to have more attributes and how do I implement two different kinds of users? And how do I separately enforce authentication for these two different kinds of users? -
