Python/Django Фильтр товаров на сайте
Изучаю django и зашел в тупик по реализации фильтров на странице списка товаров. Модели: class Products(models.Model): date_create = models.DateTimeField(auto_now_add=True, verbose_name='Дата создания') date_edite = models.DateTimeField(auto_now=True, verbose_name='Дата изменения') category = TreeForeignKey('Category', on_delete=models.SET_NULL, null=True, blank=True, verbose_name="Категория", db_index=True) nazvanie = models.CharField(max_length=350, verbose_name='Название', db_index=True) kodtovara = models.CharField(max_length=50, verbose_name='Фирменный код', null=True, blank=True, db_index=True) article = models.CharField(max_length=50, verbose_name='Артикул', null=True, blank=True, db_index=True) slug = models.SlugField(blank=True) class PropertiesProduct(models.Model): nazvanie = models.CharField(max_length=500, verbose_name='Название', db_index=True) slug_nazvanie = models.SlugField(blank=True) znachenie = models.CharField(max_length=500, verbose_name='Значение', db_index=True) slug_znachenie = models.SlugField(blank=True) detail = models.BooleanField(null=True, blank=True, verbose_name='Использовать как свойство в описании товара', db_index=True, default=True) filter = models.BooleanField(null=True, blank=True, verbose_name='Использовать для фильтра', db_index=True, default=True) register = models.BooleanField(null=True, blank=True, verbose_name='Расширенные свойства', db_index=True, default=False) tovary = models.ForeignKey('Products', on_delete=models.SET_NULL, null=True, verbose_name='Товар', db_index=True) Модель свойства товаров имеет строковые поля для хранения названий свойств и значений у товаров, и поле привязку к товару. Свойства вынесены в отдельную таблицу так как они будут прилетать из 1С должны постоянно добавлятся/удалятся/редактироваться при обмене с 1С. В DB свойства хранятся как на фото из админки. Модель свойств товара Во фронтенде хочу вывести объединенный список для фильтра к примеру: Стандартный фильтр Подскажите где почитать о реализации фильтров на сайте, или может кто то уже реализовывал фильтрацию на сайте - поделитесь. Огромное спасибо. -

Pass JS list/dict to Django Template variable to parse and render in modal
So I have a list of key value pairs (dictionary inside of a list) in a JavaScript variable I created in my base.html. Each key represents an item and each value represents a batch, so a one to many relationship using a foreign key in my models.py. My goal is to when I click on my modal, which happens to be a shopping cart, that I'll be able to somehow parse this list like I would the context dictionary inside a Django View using template tags to render as many items that are in the dictionary as there are keys. Is there a way to do this? Let me know if you need to see any of my code. Thank you. -

create new parent model in CreateView in django
i am new to django and to this site, so apologies if this has been solved before but i haven't found it So i have 2 django models ModelA(Model): ModelB(Model): modelA = ForeignKey(ModelA, on_delete=models.CASCADE) A form for the ModelB ModelBForm(ModelForm): class Meta: model=ModelB exclude=() and a view createModelBView(CreateView): model = ModelB form_class = ModelBForm the template only does {{form}} When rendered, there is a dropdown list for the ModelA field so I can choose from existing instances of the ModelA, but what if a new one needs to be created?

Calculating distance between two PointField (s) - Why is my result incorrect?
I am trying to calculate the distance between two locations in miles however the result that I am getting is incorrect. The reason I think its incorrect is because I put locations (latitude and longitude) on this website and I get the distance in miles as 0.055. Here are the details from my code PointField A : (-122.1772784, 47.7001663) PointField B : (-122.1761632, 47.700408) Distance : 0.001141091551967795 However according to the website the distance should be Distance : 0.055 miles Here is how I am calculating the distance. This is my model class modelEmp(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, blank=True) location = models.PointField(srid=4326,max_length=40, blank=True, null=True) objects = GeoManager() and this is how I calculate the distance result = modelEmpInstance.location.distance(PointFieldBLocation) where result = 0.001141091551967795 Any suggestions on what I might be doing wrong here and why my result is different from the website ? -
Django Admin page won't let me delete or add users/group. urls error
I am new to Django. I just set up my own Django server but I am having trouble with the admin page. When I try adding or deleting users or basically whenever I send POST request from Django admin page, I am getting the following error: Raised by: django.contrib.admin.options.changelist_view Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order: ^admin/ ^register/$ [name='register'] ^$ ^login/$ [name='login'] ^static\/(?P<path>.*)$ The current path, auth/user/, didn't match any of these. I tried doing python manage.py migrate but there are no migrations to apply. I am guessing this has to do with urls.py or settings.py files. re_path('^admin/', admin.site.urls) url pattern is already there, I am not sure why it is still giving the error. This is my urls.py file: from django.urls import re_path from django.contrib import admin from django.conf import settings from django.conf.urls.static import static admin.autodiscover() urlpatterns = [ re_path('^admin/', admin.site.urls), re_path('^register/$', register_page, name='register'), re_path('^$', home_page), re_path('^login/$', login_page, name='login'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) And this is settings.py import os BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) SECRET_KEY = 'key' DEBUG = True ALLOWED_HOSTS = ['myip'] # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'mysite', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', … -

Password becoming unhashed even after saving to database
I have a generic APIView where I'm overriding the create method. This is for the Group model, where I've added a password field: def create(self, request, *args, **kwargs): data = request.data data['password'] = make_password(data['password']) serializer = self.get_serializer(data=data) serializer.is_valid(raise_exception=True) self.perform_create(serializer) headers = self.get_success_headers(serializer.data) # debug code print(Group.objects.get(name=data['name']).__dict__) # shows hashed password print(serializer.data) # shows hashed password return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers) But when I query this model after leaving the create method: print(Group.objects.get(name='TestGroup').__dict__) # shows raw password Inexplicably, after checking both the serializer.data and querying the database directly in the above print statements, I confirm that I have passed a hashed password into the column. However, whenever I query this afterwards, I see that the raw password has been saved. I cannot explain how the password is becoming unhashed after saving the hashed password to the database. I am not writing to the Group model anywhere else. -
Dynamic Instance Specific Django Field Creation
I have a situation where a User model can have 'X' number of unique fields that need to be added. These fields need to have queries run on them, so I cant just add a field containing a string of JSON to it.

Disabling mod_expires in apache2 stopped server from serving static files
I tried to use browser caching with apache2 mod_expires but I had a problem that after updating some files, the browser still shows the outdated ones. So I wanted to undo the process and removed the mod_expires code from .conf file. The website is not serving images any more! It shows that "was not found on this server." although all I did was to remove the added code from configuration file and restart apache! I'm using the config file located at: /etc/apache2/sites-available/000-default.conf I tried to restart the virtual machine (I'm using Google Compute Engine). I tried to a2dismod mod_expires too. But nothing worked! Even if I tried to re-upload images! What is the problem and how can I get my website to serve back static files?

Multiple Login in same django project
I have a django project with 3 apps: CORE, FRONT-A and FRONT-B. So, each APP should have your own login page, something like: http://localhost:8080/front-a/login http://localhost:8080/front-b/login CORE app have Django Admin and Models, that should be used by FRONT-A and FRONT-B app, like a shared "jar" in java. But some login properties i have to configure in settings.xml, like this: LOGIN_URL = 'login' LOGOUT_URL = 'logout' LOGIN_REDIRECT_URL = 'FRONT-A OR FRONT-B ?' So, i have some doubts: In my case is better create one project for FRONT-A and another for FRONT-B, because i need different login pages ? If answer for (1) is NO, how can i create a login page for each APP, and grant session for each APP ? If answer for (1) is YES, can i use CORE App as shared library to my another projects ? I want to avoid "duplicate code". How can i know if i need APP onyl or create another whole PROJECT ? -

How to create unique download links for protected files that aren't from static? (django)
Overview: Hi, I made an app that takes a persons email and some other fields to construct a unique url, such as example.com/signup/confirmed/5/uygduif-78q6rjhsadkfe-IUWGIasdy756/2597646/. I'm trying to make it so this url can allow the user to download a pdf, FROM THIS URL, and not a different href location, but I can't figure it out. The point is to make it a protected file. I know I can force a user to login and stuff, but this is a pdf they get just for signing up, so account creation isn't necessary. What I tried / some thoughts: My first attempt was {% load static %} in my template, and add the href to download it in there. That allows me to open the pdf and save it, but the url for that is example.com/static/pdfs/some.pdf, which is bad, because anyone who knows html can copy/paste that location, paste it for everyone else, and now I don't get anybody's emails, but everybody gets a download. I also made another app where users can upload images to the database, then I can loop through them all afterward, but the src attribute in those <img> tag's are all at media/some_random_img_name.jpg. So using that example won't … -

Web Framework for text based simulation "games"
My intent is to build a text based simulation game, where you more or less only manipulate the database all the time (at least i assume that's how simulation games work) and where calculations take place in the background at specific times of the day. (for example for calculating games if it was a football manager, etc.) I really tried to read all content available for what web application technology is the best for my needs, but i am still not really sure and don't want to spend hours learning a technology which is not really best suited. Spring seems to be decent, however it has a pretty steep learning curve and i wonder if it would be a little "overkill" for that. Would Spark be an alternative? I like Java. Ruby on Rails also looked quite good, however i didn't really like the syntax of Ruby and the way you get boilerplates for almost all things. It was a little overwhelming at first. How about NodeJS, is it suitable for that kind of application? I did not mention all frameworks here, i would still be very happy if you can give me pro or cons for what tech could …
