How to count the content in databse django?
I am learning Django and my first project I am doing a To do application. My idea is that I put the content from the database(models.py) into tables in html ,but also on the side of the table I have put a number that starts from 1 and for every other task(content) that is put from customer in the web it also puts 2, 3 .... etc. The problem I have is that when I add a task number it becomes 2 for what I just added but also for the task that was before. This is a screenshot to understand it easily This is views.py: from django.shortcuts import render, redirect from django.utils import timezone from django.db.models import Count from .models import * from .models import __str__ # Create your views here. def home(request): count_item = todo.objects.count() all_items = todo.objects.all().order_by("created") context = {'all_items': all_items, 'count_item':count_item} return render(request, 'html/home.html', context) def add_todo(request): current_date = timezone.now() new_item= todo(content = request.POST["content"]) new_item.save() return redirect('/') def delete_todo(request, todo_id): item_to_delete = todo.objects.get(id=todo_id) item_to_delete.delete() return redirect('/') This is home.html: {% extends 'html/main.html' %} {% load static %} {% block content %} <style> </style> <nav class="navbar navbar-dark bg-dark"> <div class="container-fluid"> <a class="navbar-brand" href="#">TO DO APPLICATION</a> <form class="d-flex" … -
Django Admin does not encrypt password
I'm making a project that there will be an admin, and He/She will register the users. But when I create a user by admin interface, the password is not being encrypted. What could it be? user model from django.db import models from django.contrib.auth.models import AbstractUser from django.contrib.auth.models import BaseUserManager # Create your models here. class UsuarioManager(BaseUserManager): use_in_migrations = True def _create_user(self, email, password, **extra_fields): if not email: raise ValueError('Email é obrigatorio') email = self.normalize_email(email) user = self.model(email=email, username=email, **extra_fields) user.set_password(password) user.save(using=self._db) return def create_user(self, email, password=None, **extra_fields): extra_fields.setdefault('is_superuser', False) return self._create_user(email, password, **extra_fields) def create_superuser(self, email, password, **extra_fields): extra_fields.setdefault('is_superuser', True) extra_fields.setdefault('is_staff', True) if extra_fields.get('is_superuser') is not True: raise ValueError('Superuser precisa ter is_superuser=True') if extra_fields.get('is_staff') is not True: raise ValueError('Superuser precisa ter is_staff=True') return self._create_user(email, password, **extra_fields) class Usuario(AbstractUser): USERNAME_FIELD = 'email' email = models.EmailField(('email address'), unique=True) REQUIRED_FIELDS = [] # removes email from REQUIRED_FIELDS funcionario = models.BooleanField("funcionario", null=True, blank=True) cliente = models.BooleanField("cliente", null=True, blank=True) def __str__(self): return super().first_name + " " + super().last_name objects = UsuarioManager() As I create a superuser on cmd, the password is encrypted normally. -
Django pagination not working. Object list is rendering items but not dividing into pages
I'm currently working on an e-commerce site and I'm trying to create a product list page that spans into another page after 4 items have been displayed. rendering the page doesn't produce any error but all items in the database are displayed on the same page and remains the same even after switching to another page. Here's my views.py: from django.shortcuts import render, get_object_or_404 from .models import Category, Item from django.core.paginator import Paginator def item_list(request, category_slug=None): category = None categories = Category.objects.all() items = Item.objects.filter(available=True) if category_slug: category = get_object_or_404(Category, slug=category_slug) items = items.filter(category=category) paginator = Paginator(items, 4) page_number = request.GET.get('page') page_obj = paginator.get_page(page_number) return render(request, 'item/list.html', {'category': category, 'categories': categories, 'page_obj': page_obj, 'items': items}) my urls.py file: from django.urls import path from . import views app_name = 'shop' urlpatterns = [ path('', views.item_list, name='item_list'), path('<slug:category_slug>/', views.item_list, name='item_list'), path('<int:id>/<slug:slug>/', views.item_detail, name='item_detail'), pagination snippet from the template <nav class="d-flex justify-content-center wow fadeIn"> <ul class="pagination pg-blue"> <!--Arrow left--> {% if page_obj.has_previous %} <a href="?page={{ page_obj.previous_page_number }}">Previous</a> {% endif %} <span class="current"> Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}. </span> {% if page_obj.has_next %} <a href="?page={{ page_obj.next_page_number }}">Next</a> {% endif %} </ul> </nav> and the logic that displays the products <div class="row … -
Django models: How to filter by multiple values at once?
I'm working on a social network project for learning purposes and I'm trying to figure out the best way to make this query: def following(request, user_username): user = User.objects.get(username=user_username) try: following_users = user.following.all() following_posts = [] for following_user in following_users: following_posts.append(Post.objects.filter(username=following_user.username)) except: return JsonResponse({"error": "There was an error loading the following posts"}, status=400) following_posts = following_posts.order_by("-timestamp").all() return JsonResponse([post.serialize() for post in following_posts], safe=False) I'm trying to get the posts of the users that the user is following in the social media, ordered by reverse chronological order ("timestamp"). And, to do that, I tried first getting all the users that the user follows (following_users = user.following.all()) and then getting all the posts these users has one by one (in the for loop). The problem is that the order_by function only works with QuerySet, and the following_posts is a list. Not only that, I don't think that this is a good way to make this query even if it worked. Can I get all these posts at once without a for loop? Anyway, these are the models that are involved in this query: class User(AbstractUser): profile_picture = models.CharField(max_length=100, default="https://cdn.onlinewebfonts.com/svg/img_568656.png") followers = models.ManyToManyField('self', blank=True) following = models.ManyToManyField('self', blank=True) join_date = models.DateTimeField(auto_now_add=True) def serialize(self): … -

How to generate a PDF from content on the page - Django
I've got a model with a field for a EULA (it's kind of long, maybe about 8500 characters). This EULA is rendered to the page like so: <div class="collapse" id="library-eula"> <div class="card"> <div class="card-body"> {{ library.eula|markdownify|safe }} <a href="#" class="btn btn-primary" role="button"> Download PDF </a> </div> </div> </div> That Download PDF button is meant to be for downloading the content in the card (library.eula) as a PDF. I started with the example from Django's docs. I copied the code directly from that page. When I use this code as is in a CBV with a get method (eg, as a test -> p.drawString(100, 100, "Test page")) and then hook up a URLconf: # Download a PDF path('download/pdf', DownloadPDFView.as_view(), name='download-pdf'), And add this to the template: <a href="{% url 'download-pdf' %}" class="btn btn-primary" role="button"> Things work fine... But I'm having a hard time figuring out how to actually stick the library.eula string into the PDF. I've tried a few things but I feel like I'm going nowhere. -
Django templates url - differentiate between same url names
in my application I've got a view called download_document which works fine using {% url 'download_document' some_id %} . Installing a 3rd party app into the virtual environment cause trouble because this app has also the download_document view (also accepting one ID parameter) with the same urlname. If I'd like to use both with this name, can I somehow make the difference between them? For instance using both cases in the same template file? Python: 2.7 Django: 1.11.16 Debian . -

Should you access cleaned_data directly in views or have a method belonging to the given form that handles working with cleaned_data?
I started experimenting with django few afternoons ago and I have an app with a custom form in which I authenticate user the following way: if form.is_valid(): username = form.cleaned_data['username'] password = form.cleaned_data['password'] ... work with username and password ... However, I also read on some webpage (witch I no longer have in my search history :/) that you should not access cleaned_data like that and that it is better to hide using of cleaned_data to a custom method. And do something like this: if form.is_valid(): form.process() I don't think that it should matter much. Nonetheless, I'm curious which way is more preferable and django-like. Thanks! -

VS Code does not see sqlite3
I am building a website using Django and wanted to inspect my database using command: python manage.py dbshell however surprisingly I got CommandError: You appear not to have the 'sqlite3' program installed or on your path. I am using VS Code for my project and got the error in command prompt terminal of VS Code. I am saying surprisingly because I have already created my models before with commands python manage.py makemigrations and python manage.py migrate. These commands also don't work right now. It is impossible that sqlite3 is not installed because python installs it inherently. I assume PATH variable is also not an issue as I added it and can run sqlite3 outside of VS Code if I open command prompt from the start menu of windows. What can be the reason of this corruption/problem and how can I fix it ? This is screenshot of start menu command prompt : This is screenshot of VS Code : -

Any tips? html <div class="other"> {% if object.photo_1 %} <div class="list-one-images"> <img class="hover-shadow cursor" onclick="openModal();currentSlide(1)" src = "{{ object.photo_1.url }}"> </div> {% endif %} {% if object.photo_2 %} <div class="list-one-images"> <img onclick="openModal();currentSlide(2)" class="hover-shadow cursor" src = "{{ object.photo_2.url }}"> </div> {% endif %} {% if object.photo_3 %} <div class="list-one-images"> <img onclick="openModal();currentSlide(3)" class="hover-shadow cursor"src = "{{ object.photo_3.url }}"> </div> {% endif %} {% if object.photo_4 %} <div class="list-one-images"> <img onclick="openModal();currentSlide(4)" class="hover-shadow cursor" src = "{{ object.photo_4.url }}"> </div> {% endif %} </div> model: class Oglas(models.Model): agent = models.ForeignKey(Agent, on_delete = models.DO_NOTHING) title = models.CharField(max_length=120) address = models.CharField(max_length = 120) area = models.CharField(max_length=120) description = models.TextField(blank = True) price = models.IntegerField() bedrooms = models.DecimalField(max_digits=2, decimal_places=1) bathrooms = models.DecimalField(max_digits=2, decimal_places=1, blank = True, null = True) garage = models.IntegerField(default = 0) sqft = models.IntegerField() kategorii = (('prodava', 'prodava'),('iznajmuva','iznajmuva')) kategorija = models.CharField(max_length = 10, choices= kategorii, null = True) lot_size = models.DecimalField(max_digits=5, decimal_places=1) photo_main = models.ImageField(upload_to = 'photos/%Y/%m/%d/') … -
How to solve 'module' object is not iterable in django

Generic detail view PostDetailsText must be called with either an object pk or a slug in the URLconf
I am stuck trying to figure out how to fix this error. I'm trying to list all available categories and to display post a single overview. I know what the error is referring to (path), but I don't understand how to fix it. Here is my main url.py file urlpatterns = [ path('', PostDetailsText.as_view(), name='post_more_details'), ] These are my views for lisitng and details: class CategoryListing(TemplateResponseMixin, View): model = Post template_name = 'publications/posts/listing_posts.html' def get(self, request, category=None): categories = Category.objects.annotate(total_posts=Count('posts')) posts = Post.objects.annotate(total_modules=Count('modules')) if category: category = get_object_or_404(Category, slug=category) posts = posts.filter(category=category) return self.render_to_response({'categories': categories, 'category': category, 'posts': posts}) class PostDetailsText(DetailView): model = Post template_name = 'publications/posts/posts_details.html' The urls of the app: urlpatterns = [ path('category/<slug:category>/', views.CategoryListing.as_view(), name='categories_listing'), path('<slug:slug>/', views.PostDetailsText.as_view(), name='post_details'), ] This is how it looks like my html for listing the items: <div class="contents"> <h3>Categories</h3> <ul id="modules"> <li {% if not category %}class="selected"{% endif %}> <a href="{% url 'post_more_details' %}">All</a> </li> {% for s in categories %} <li {% if category == s %}class="selected"{% endif %}> <a href="{% url 'categories_listing' s.slug %}"> {{ s.subject }} <br><span>{{ s.total_posts }} posts</span> </a> </li> {% endfor %} </ul> </div> <div class="module"> {% for post in posts %} {% with category=post.category %} … -
Webpack configuration for react and django app
I am planning to make a boilerplate in GitHub between React and Django To facilitate me later When I start a project I chose the connection method React as Django app django-admin startapp frontend The problem I am facing now is that I am using the Django templates. I cannot split packages using wepback because there must be {load static} {static ''index.js"} However, I cannot use Splitchuncks in configuring a webpack or HTML plugin to insert script tags into HTML. The entire code must be inside one js file and that too with CSS webpack.config.js const path = require("path"); const webpack = require("webpack"); // const TerserPlugin = require('terser-webpack-plugin'); const HtmlWebpackPlugin = require("html-webpack-plugin"); const MiniCssExtractPlugin = require("mini-css-extract-plugin"); const devMode = process.env.NODE_ENV !== "production"; module.exports = { entry: "./src/index.js", output: { path: path.resolve(__dirname, "./static/frontend"), filename: "[name].js", }, module: { rules: [ { test: /\.js$/, exclude: /node_modules/, use: { loader: "babel-loader", }, }, { test: /\.css$/, use: [ devMode ?

Django- update a DateField model entry to be a string as a default
I have a function in my Django model: def add_default_date This function, if called from the view, checks to see if publish_date is None and if it is, I'd like to change publish_date to be text: "Date Needed". However right now when I do this I get an error: "'Date Needed' value has an invalid date format. It must be in YYYY-MM-DD format.". It appear that I'm trying to assign a string to a DateField but it's not working. Is there anyway to do this? Models.py: class Byte(models.Model): """Model for databyte content.""" publish_date = models.DateField(blank=True, null=True) def add_default_date(self): if self.publish_date is None: self.publish_date = "Date Needed" Views.py: bytes = Byte.objects.order_by( F('publish_date').desc(nulls_last=True) ) for b in bytes: Byte.add_default_date(b) b.save()
