Deploying a Django web application that uses SQL Server
I am getting ready to deploy my Django app, with a SQL Server backend, but I'm not sure where to even start. I've done a lot of research and reading, but I have not found any clear path to follow. Does it have to be hosting with AWS, Azure, or the like? Can it instead be hosted on my Windows Server (on-prem)? -
Apache2 not starting on Debian server after following dev.to guide
I am trying to host my Django website on my Debian 12 server but I am encountering an error even after following the guide on dev.to. The error is that Apache2 is not starting and is showing the following message: Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xeu apache2.service" for details. After running systemctl status apache2.service it is showing that without matching section. I have tried the following steps to fix the problem: I have checked that the Apache2 service is not running everytime restarting the server. I have checked that the port 80 is not being used by another process. I have cleared the Apache2 configuration files. I have reinstalled Apache2. However, I am still getting the same error. Can anyone help me to fix this problem? <VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host.

Change the url that search_form hits during search in Django admin changelist page
I have a custom implementation for the changelist page in the Django admin, such that a custom query parameter is provided in the url. For example, it is like this: admin/app_label/model_name/?custom_parameter=value Although I have made the changes I needed to filters and action to work using this url, I have an issue with search. Hitting the search in changelist page, I see that it hits the normal url admin/app_label/model_name/ . This is an issue since I need the custom parameter in the GET request to appropriately handle things in the django admin backend. I have also seen the search_form.html file that renders the search element. Is there a way to define the url that the search will hit, either from the backend or somehow via the javascript of the search_form.html, since I also have the custom_parameter provided in the context of the html page? -

Django - try to refresh the page when the basket is empty
I'm sort of new with Django and I ran through an issue. I'm doing a E-commerce project. I'm sending a post request to django basket view and return the function back with HttpResponse in order to change the product details in the basket. The issue is: once the product quantity went from 1 to 0, the page is not displaying an empty basket in the default way. Is that impossible to return a HttpResponseRedirect and JsonResponse at the same time, right? Do you guys have any idea how to do it?Can I do something in the ajax part to refresh the basket page? Here's are the codes: Views.py def basket_delete(request): basket = Basket(request) basketqty = basket.__len__() if request.POST.get('action') == 'post': product_id = int(request.POST.get('productid')) basket.delete(product=product_id) basketqty = basket.__len__() #calculating the basket quantity baskettotal = basket.get_total_price() response = JsonResponse({'qty':basketqty, 'subtotal':baskettotal}) return response Ajax in the html template <script> $(document).on("click", ".delete-button", function (e) { e.preventDefault(); var prodid = $(this).data("index"); $.ajax({ type: "POST", url: '{% url "basket:basket_delete" %}', data: { productid: $(this).data("index"), csrfmiddlewaretoken: "{{csrf_token}}", action: "post", }, success: function (json) { $('.product-item[data-index="' + prodid + '"]').remove(); if (json.qty == 0) { total = 0 subtotal = 0 } else { total = (parseFloat(json.subtotal) + … -

Change city slug on django-cities to only have city name with hyphens
I am using django-cities in my project, and I am stuck at an issue which I can't seem to be able to overcome on my own. I basically need the slug field of the City model to only list the city name, with hyphens if the name has spaces. This is the standard behaviour of the Country model slug. Instead, the City model returns something like [id]-[city]. So the slug for Country is: United-Arab-Emirates But the slug for City is: 292968-Abu-Dhabi I think I've identified where this is generated in django-cities. The BaseCity model has a field slug_contains_id which is set to True, then the slugify method adds it to the slug before the city name: django-cites.models: class BaseCity(Place, SlugModel): slug_contains_id = True name_std = models.CharField(max_length=200, db_index=True, verbose_name="standard name") country = models.ForeignKey(swapper.get_model_name('cities', 'Country'), related_name='cities', on_delete=SET_NULL_OR_CASCADE) region = models.ForeignKey(Region, null=True, blank=True, related_name='cities', on_delete=SET_NULL_OR_CASCADE) subregion = models.ForeignKey(Subregion, null=True, blank=True, related_name='cities', on_delete=SET_NULL_OR_CASCADE) location = PointField() population = models.IntegerField() elevation = models.IntegerField(null=True) kind = models.CharField(max_length=10) # http://www.geonames.org/export/codes.html timezone = models.CharField(max_length=40) class Meta: abstract = True unique_together = (('country', 'region', 'subregion', 'id', 'name'),) verbose_name_plural = "cities" @property def parent(self): return self.region def slugify(self): if self.id: return '{}-{}'.format(self.id, unicode_func(self.name)) return None But what I'm unable to … -

Django Docker container without database container - best practise?
I am a little bit confused about the database Docker container. I read everywhere that is not good practise to dockerize a database, for example here. But if I search for Django Docker container then I see almost in every Docker Compose file that a Postgres database container is included. For example I have this docker-compose.yml file: version: '3.9' services: app: build: context: . args: - DEV=true ports: - "8000:8000" volumes: - .:/app command: > sh -c "python manage.py migrate && python app/manage.py runserver 192.168.1.65:8000" env_file: - variables.env depends_on: - db db: image: postgres:13-alpine container_name: postgres volumes: - dev-db-data:/var/lib/postgresql/data environment: - POSTGRES_DB=dzijn - POSTGRES_USER=zijn - POSTGRES_PASSWORD=password volumes: dev-db-data: dev-static-data: It has also a Docker database. Is it better to omit the database container in the Docker Compose file and for example to store the database in a cloud service? Because I am using Microsoft Azure for the hosting. -
General way of iterating over a dictionary containing multiple mpld3 graph images in Django?
I am working on a personal project. One part of this is to display multiple histograms on a webpage. So far, I have been able to get this to work using the following code: views.py: import pandas as pd import matplotlib.pyplot as plt,mpld3 import scipy.stats as stats import numpy as np for column in df.columns: fig=plt.figure() plt.hist(df[column]) histogram=mpld3.fig_to_html(fig) context[f"{column}Histogram"]=[histogram] HTML Code: {% for elem in PregnanciesHistogram %} {{elem|safe}} {% endfor %} {% for elem in GlucoseHistogram %} {{elem|safe}} {% endfor %} {% for elem in BloodPressureHistogram %} {{elem|safe}} {% endfor %} {% for elem in SkinThicknessHistogram %} {{elem|safe}} {% endfor %} {% for elem in InsulinHistogram %} {{elem|safe}} {% endfor %} {% for elem in BMIHistogram %} {{elem|safe}} {% endfor %} {% for elem in DiabetesPedigreeFunctionHistogram %} {{elem|safe}} {% endfor %} {% for elem in AgeHistogram %} {{elem|safe}} {% endfor %} I do see all the histograms on my webpage, but the problem is that all of the HTML code uses hardcoded keys in the dictionary. Is there a general way of writing what I wrote in this HTML code, using a for loop, without hardcoding the keys from the dictionary? I would appreciate it if someone could tell me … -
How to (conditionally) remove SCRIPT_NAME from MEDIA_URL in urls.py
Situation: working in Debug=True mode in Django. I want to serve files from the media root, so I follow the documentation hint: urlpatterns = [ # ... the rest of your URLconf goes here ... ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) And it works perfectly (remember to read the note: MEDIA_URL should be local i.e. media/. Don't put a / in front of it. Important!). I have a media resource called 123456.txt, in the admin interface I get the link: /media/123456.txt. Now I move to Apache (still in debug), but I run this Django site in a subfolder of the server, and everything works fine, thanks to the WSGI variable SCRIPT_NAME which gets prepended to all URIs. So just to be clear, I have https://example.com/subfolder as the root for the Django site and the previous media resource called 123456.txt, in the admin interface I get the link: /subfolder/media/123456.txt. So the link is correct. When I request the resource https://example.com/subfolder/media/123456.txt, Apache recognizes the subfolder and sends to Django a request for media/123456.txt, as expected. The problem is that the url pattern created by the static() helper function now includes the SCRIPT_NAME prefix, so when I click on the resource, I get an exception … -
