JavaScript, CSS, and Image File Imports Won't Load When Running Live Server On Pycharm with Django
This might be a very basic question but I've been stuck on it a while and ended up deciding to ask on here...greatly appreciate any help! So I've just been making a basic website using pycharm and django and everything loads fine when I run the code through a browser. However, when I use runserver, it only shows the HTML code and not any of the files I have imported including javascript files, css files, and image files. All of my files are contained within the same templates folder. This is the error I receive in the terminal when opening up a live server.

Python Django Validation Error Message in Dictionary Form
I am working on certain validation and wants to raise human readable validation Error message in form of dictionary but I am stuck how to pass error messages and dictionary values inside dictionary here is what I have tried in other way: def _is_valid(self): boarding_points = self._location.point.all() if not set(self._data.get('point')).issubset(set(boarding_points)): for boarding_points_name in self._data.get('point'): raise ValidationError({'point', boarding_points_name, 'is not in location', self._location.name} ) above method is surely a wrong approach as it is set and secondly gives validation error message as [ "{'point', 'is not in location', 'London', <BoardingPoint: Manchester>}" ] I want error message as {'point': Boarding point: Manchester is not in Location: London} how can I do with python dictionary way to throw readable error message?TT -

how to configure Aapahe mod-wsgi for python 3.6 which is by default configured with python 2.7?
Hye everyone.. I have installed Python 3.6 and created a virtual environment and installed all required libraries including Django in that virtual environment. I want to host a django application on Linux server with wsgi but it says ImportError: No module named django.core.handlers.wsgi from what I search and think this problem is because the server is not accessing my virtual environment of python 3.6 where django is installed. My server details are: Python 3.6 [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)] Django Version :3.1.1 Server version: Apache/2.4.46 (cPanel) Server Can anybody tells me how the Apache will get the djnago from my virtual environment? In other words how I can configure my server which is configured with python 2.7 to python 3.6 with libraries installed in virtual environment. Any help will be appreciated. -

Django create() argument after ** must be a mapping, not list
I'm creating a writable nested serializer using DRF, I've been following the official documentation (https://www.django-rest-framework.org/api-guide/relations/#writable-nested-serializers).

Signal in Model of Django
I ask you this question that I cannot find a solution. I am entering records in the Django Admin, so I enter the functions in the model.

Is it possible to upload xlsx file to aws S3 storage on coding in django?
Here is my code (I am writing some data to existing xlsx file) wb = load_workbook(EXCEL_FILE) # it is a directory to my excel file sheets = wb.sheetnames Sheet1 = wb[sheets[0]] Sheet1.cell(row = 4, column = 5).value = user_surname Sheet1.cell(row = 5, column = 5).value = user_name Sheet1.cell(row = 6, column = 5).value = address Sheet1.cell(row = 7, column = 5).value = city_and_country Sheet1.cell(row = 8, column = 5).value = phone_number Sheet1.cell(row = 9, column = 5).value = passport length = len(products) rows = [x for x in range(1,length+1)] sum_list = [] for (row,product,count,price,attr_name,attr_value) in zip(rows,products,product_count,product_price,attr_names,attr_values): length = len(attr_name) additional_info = [] for name,value in zip(attr_name,attr_value): name_and_value = name + ': ' + value additional_info.append(name_and_value) print(additional_info) Sheet1.cell(row = 3+row, column = 7).value = product + "--" +"-".join(additional_info) Sheet1.cell(row = 3+row, column = 9).value = count Sheet1.cell(row = 3+row, column = 10).value = price real_price = price[0:-2] total_one_product = int(real_price) * count sum_list.append(total_one_product) currency = Currency.objects.last() uzs = currency.UZS if currency else 10300 total_price_usd = sum(sum_list)/uzs Sheet1.cell(row = 10, column = 14) .value = round(total_price_usd,2) wb.save("demo.xlsx") # file is being saved to the directory inside of Project and sent to courier as an attachement Now i want to save it to … -
Using iframes with bootstrap carousal
I am working on a django application. In the application, I want to display a few youtube videos in the landing page. For adding and displaying the videos, I am using django-embed-video. Right now when I add videos to the webpage, they are displayed one after the other. I would like to display these videos in the bootstrap carousal. But adding them to the bootstrap carousal does not seem to work. This is my code so far <div id="carouselVideoControls" class="carousel slide" data-ride="carousel"> <ol class="carousel-indicators"> <li data-target="#carouselVideoControls" data-slide-to="0" class="active"></li> <li data-target="#carouselVideoControls" data-slide-to="1"></li> <li data-target="#carouselVideoControls" data-slide-to="2"></li> </ol> <div class="carousel-inner"> {% for i in videos %} <div class="carousel-item active"> {% video i.video 'medium' %} </div> {% endfor %} </div> <a class="carousel-control-prev" href="#carouselVideoControls" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="carousel-control-next" href="#carouselVideoControls" role="button" data-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="sr-only">Next</span> </a> </div> When this code is run, the carousal breaks. The next and previous buttons in the carousal do not work and only the first video is displayed indefinitely. FYI: The carousal and the video themselves work separately. If I were to use images in the bootstrap carousals instead of videos from django-embed-videos, the carousal works. It is only when, I add the … -
Unable to redirect to new page Django
I am new to Django. I am building a multiple page website via Django. on the main page I am using an onclick event and passing the data to views.py via AJAX. the issue is that in the command prompt everything is running smoothly. the function to which Ajax call was made is being called. the data is being fetched but the URL is not changing. If we copy the URL from new URL from cmd and paste it in browser window, it is working the way it is suppose to work. Can someone tell me what might the issue.
