How to automatically built 3 column cards inside of a row html with django
i am new at django and i am learning html too. So, i want to do a simple question (maybe). I am developing a little project in django, and i have a problem with a frontend part. Especifically in a HTML part. as you can see in the picture, i am developing a kind of a ecommerce. But i have a mistake in my HTML part. I don´t want to show the cards of the articles like a list of rows, like the image. I want want to show 3 cards articles by columns, automatically done when i add a new article. Just like this another picture (made from paint :P): This is my HTML, to that part: <div class="row"> <div class="col-lg-7"> <h5>Tipo de vista:<button class="btn btn-lg" type="reset""><a href="{% url 'adminview:article' %}"><h6>Lista</h6></button></a>/<button class="btn btn-lg" type="reset""><a href="{% url 'adminview:cuadricula' %}"><h6>Cuadrícula</h6></button></a></button></button></h5> <div class="card mb-8"> <div class="card-header"> <i class="fas fa-chart-bar"></i> Productos disponibles</div> <div class="card-body"> <div class="table-responsive"> <table class="table table-bordered" id="dataTable" width="100%" cellspacing="0"> {% if articulo %} {% for articulo in articulo %} <div class="col-lg-4 col-md-6 mb-4"> <div class="card h-100 w-100"> <a href="article/id/{{ articulo.id }}"><img class="card-img-top" src="{% url 'home:preload_image' pk=articulo.pk %}" alt=""></a> <div class="card-body"> <h4 class="card-title"> <hr class="sidebar-divider"> <a href="article/id/{{articulo.id}}">{{articulo.nombre_producto}}</a> </h4> <h5>{{articulo.precio}} bsS</h5> <p … -
Django+PostgreSQL Not Able to Fin Object From DB Right After Create It

Django should I manage users in a separate startapp?
In Django 2.2, if I plan to make authentication its own service in the future and serve requests through DRF, should I put my User model in a separate app from my regular "functional apps"?

How to create a foreign key set for each file in a list of files with django
I am trying to upload multiple images to my database with django. I would like each file to be stored separately as a foreignkey to the main product.So basically what I mean is that there will be products and then each product will have multiple foreign keys that are images. Django isn't storing the images to the database at all. Here's my code: class product(models.Model): title = models.CharField('', max_length=100, db_index=True) price = models.CharField('', max_length=100, db_index=True) description = models.CharField('', max_length=100, db_index=True) class productimage(models.Model): product = models.ForeignKey(product, on_delete=models.CASCADE) product_images = models.FileField(blank=True) if request.method == "POST": title = request.POST.get("title") price = request.POST.get("price") description = request.POST.get("description") products = product(title=title,description=description,price=price) products.save() for image in request.FILES.getlist("images"): product_images = image products.productimage_set.create(product_images = product_images) return render(request,'selling/addproduct.html') So basically I would like each product to have a list of images stored as a foreign key to the main product. -

GeoDjango: How to perform a query of spatially close records
I have two Django models (A and B) which are not related by any foreign key, but both have a geometry field. class A(Model): position = PointField(geography=True) class B(Model): position = PointField(geography=True) I would like to relate them spatially, i.e. given a queryset of A, being able to obtain a queryset of B containing those records that are at less than a given distance to A. I haven't found a way using pure Django's ORM to do such a thing. Of course, I could write a property in A such as this one: @property def nearby(self): return B.objects.filter(position__dwithin=(self.position, 0.1)) But this only allows me to fetch the nearby records on each instance and not in a single query, which is far from efficient. I have also tried to do this: nearby = B.objects.filter(position__dwithin=(OuterRef('position'), 0.1)) query = A.objects.annotate(nearby=Subquery(nearby.values('pk'))) list(query) # error here However, I get this error for the last line: ValueError: This queryset contains a reference to an outer query and may only be used in a subquery Does anybody know a better way (more efficient) of performing such a query or maybe the reason why my code is failing? I very much appreciate. -

How to make urls in django middleware more dynamic when using get.path
I wrote a custom middleware in my django application. Basically I added a counter which increments whenever a site is viewed. To filter out the admin site and condition my views, I use basic conditionals like so: My middleware.py class GetUrlMiddleware(): def __init__(self, get_response): self.get_response = get_response # One-time configuration and initialization. def __call__(self, request): # Code to be executed for each request before # the view (and later middleware) are called. response = self.get_response(request) if request.path.startswith('/admin/'): pass elif request.path == ('/jobs'): Counter.objects.update(total_views=F('total_views')+1) Counter.objects.update(job_list_site_views=F('job_list_site_views')+1) elif request.path == ('/'): Counter.objects.update(home_site_views=F('home_site_views')+1) Counter.objects.update(total_views=F('total_views')+1) elif request.path.startswith('/jobs/'): Counter.objects.update(total_views=F('total_views')+1) # Code to be executed for each request/response after # the view is called. return response Here are my urls: urlpatterns = [ path('jobs', ListJobView.as_view(), name="list_jobs"), path('jobs/<int:id>/', DetailJobView.as_view(), name="detail_jobs"), path('jobs/new', CreateJobView.as_view(), name="create_job"), path('jobs/update/<int:id>/', UpdateJobView.as_view(), name="update_job"), path('jobs/delete/<int:id>/', DeleteJobView.as_view(), name="delete_job"), ] Now that works. But I would like to make it a bit more dynamic, so I was thinking about using the url-namespaces instead of hardcoding the path. But what I tried so far doesn't work. Also I don't know how I can condition my detail view in which I pass ids. Is there any way to do that? Any help is appreciated, thanks in advance. -
Why do Django apps required `manage.py` for everything instead of using `__init__py`?
If copy over some manage.py lines to my __init__.py all my views.py and models.py files can be imported from anywhere without requiring python manage.py shell: import os import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'myproject.settings') django.setup() That way I can import my submodules in __init__.py (further down): import glob modules = glob.glob(os.path.join(os.path.dirname(__file__), '*.py')) __all__ = [os.path.basename(f)[:-3] for f in modules if os.path.isfile(f) and not f.endswith('__init__.py')] from . import * That way I can do this from any directory: import myproject as mp mp.models.MyModel.objects.get(field_name='value') This is handy when importing data or doing data migrations away from the project fixtures directory. Is there anything wrong with this? If not, why doesn't Django do it this way by default when you python manage.py startproject? -

Django Development Server
Just to give you some general context of what I am doing, I am currently in the process of making a mobile app for university students to notify them when a seat becomes available in a previously full course. For my project architecture, my web service stack is setup very similar to a LAMP stack: Linode cloud ubuntu instance for linux OS, Apache2 for my HTTP Server, MySQL for my relational database management system, and Python for my programming language. Also, to gather the data needed for my project, I am going to web-scrape via a python script with beautiful soup and selenium (for timed delays when loading the webpages), and plan on implementing cron jobs for minutely scrapes to continuously update my database on my LAMP Stack (specifically the number of seats available in a particular course) which will then send any updates of newly open seats to the mobile app (which I will code in the future, but have not gotten to yet). I am having a LOT of trouble installing Django on my server. Thus far, I am able to starting up the Django development server in terminal, but when I try to access the project / … -
Django: How can I send an email with a description that includes all inputs from a contact form?
I have a Django-built website which sends an email to a certain employee after a contact form is submitted. The relevant code in my views.py file that does this is as follows: def quote_req(request): submitted = False if request.method == 'POST': form = QuoteForm(request.POST, request.FILES) description = request.POST['company'] if form.is_valid(): form.save() # assert false send_mail('Contact Form', description, settings.EMAIL_HOST_USER, ['sample@gmail.com'], fail_silently=False) return HttpResponseRedirect('/quote/?submitted=True') else: form = QuoteForm() if 'submitted' in request.GET: submitted = True return render(request, 'quotes/quote.html', {'form': form, 'page_list': Page.objects.all(), 'submitted': submitted}) The website successfully sends the email; however, at the moment I am limited to sending only one input from the contact form (in this case, 'company') for the email description (which is utilized in the send_mail command). Does anyone know if I can modify the request.POST command or use another type of method to send more than one contact form input for the email description (i.e., 'company', 'phone', 'address', etc.)? -

Possible to use get_absolute_url in {% url %} tags without the model object?
I have a navbar where user can log in and after logging in, the user will have a dropdown menu with a link to his/her profile. Here are my codes: navbar.html: {% url 'students:student_profile_view' as student_profile_url %} {% if request.user.is_authenticated %} <!-- User Dropdown Menu --> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> <i class="far fa fa-user"></i> {{request.user.first_name}}</a> <div class="dropdown-menu" aria-labelledby="navbarDropdown"> <a class="dropdown-item" href="{{ student_profile_url }}">Profile</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="{{ logout_url }}">Logout</a> </div> </li> students/urls.py: path('profile/<slug:slug>/', views.student_profile_view, name='student_profile_view'), students/model.py: from django.contrib.auth.models import User from django.utils.text import slugify class StudentProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) slug = models.SlugField(blank=True, unique=True) avatar = models.ImageField(upload_to='student_profile/', null=True, blank=True) description = models.CharField(max_length=120, null=True, blank=True) objects = models.Manager() def save(self, *args, **kwargs): self.slug = slugify(self.user) super(StudentProfile, self).save(*args, **kwargs) def __str__(self): return self.user.username def get_absolute_url(self): # return 'students:student_profile_view', (), {'slug': self.slug} return reverse("students:student_profile_view", kwargs={"slug": self.slug}) Navbar.html is a base template, it's not being rendered through a view where I could've passed an object and then called object.get_absolute_url Right now the profile button in my navbar dropdown menu is not working as it's not finding a reverse match for the user.

Upgrade from Django 2.1 to 2.2: problem with prepopulated field
Today I've updated my Django version from 2.1 to 2.2 and I've noticed that the prepopulated field don't work. Based your experience which are the things to see before do the update? In my site there are this plugins: - django-tinymce4-lite - django-filebrowser - django-grappelli I can exclude compatibility problems between Django 2.2 and one of this plugins because I've made a test with a new empty project and the prepopulated field work fine. -
JS: function not defined
I have JS script function that holds cart items to order food. This function is passed with 2 parameters ID and price. My script file looks like <script> function addtocart(mitem, mprice) { var price = String(mprice) var mobj = { String(mitem): price } var storeobj = JSON.stringify(mobj) localStorage.setItem('cart', storeobj) } </script> My button looks like this <p style="position: absolute; bottom: 0px"><button class="button" style="width: 200px" onclick="addtocart( '{{M.Menu_Item}}', '{{M.Menu_ItemPrice}}' )" >Add to Cart</button> When I click on the button in developer console in chrome says that addtocart function not defined. I did read about on click listens but I have to pass the parameter for each button click, which is different. What might I be doing wrong? -
