Django/HTMX - How to stop resetting selected option when search form is submitted?
I want to implement a search form that has a Product ID field and a and Product locations select field in which the list of locations should be populated based on the Product ID entered. For the Product ID, I'm using HTMX, to get the list of available locations dynamically. Which means, whenever I type any Product ID, I want to get all the available Locations for that ID without having to click on a button. And when the Location is selected and the Search button is clicked the search result should be displayed in the page. BUT the problem is, whenever I click select an option and click on the Search button, It reloads the page and resets the selected option! and this is not what I want, I want to keep the location as selected when the search result is displayed. How can I stop resetting the select input after selecting when the Search button is clicked and the page is reloaded?

How to update a post in Django using the same manual-written form for creating it?
I have a form in which I can create a new post, which works perfectly. Now I want the same form to be filled when clicking on a link in order to update the post. I've found lots of tutorials, but all of them were using the form in 'form.py'. I don't have a form base on my model, I've created the form myself and now I want it to go to the same form-page and fill up the data, so it can edit the post. When this link is clicked, which each post has one, I want it to go to the form-page and fill the form, so I can edit it. This link is in home.html <a href=""><img width="48" height="48" src="https://img.icons8.com/fluency/48/pogchamp.png" alt="pogchamp"/></a> This is my form. I use it for creating a new post, but I also want to use it for editing. It's add_edit.html <form class="form text-center" action="{% url 'addEdit' %}" method="POST"> {% csrf_token %} {% if messages %} {% for message in messages %} <p class="text-danger text-center fs-3 vov fade-in-up">{{ message }}</p> {% endfor %} {% endif %} <div class="mb-3 col-11 col-md-4 col-lg-3 mx-auto"> <label for="title" class="form-label float-start" id="title_lable">TITLE</label> <input type="text" class="form-control" name="title" id="title" placeholder="U_U" required> … -

What am I missing to have 'move_up_down_links' display on 'ListAdmin' page using django-ordered-model?
I use django-ordered-model==3.7.4 in my project to create an ordered model. I want to have a way to reorder list items via Django Admin.

Django channels consumer how to disconnect at server side

As you can see, a Sale, may have multiple SaleItems, a SaleItem refers to a single Product and the Sale itself, and has a quantity. Finally, a Sale represents a set of products that were sold by us to a specific merchant . I want to get the number of items of each product that were sold to each merchant. An example of the output I'm trying to achieve (id replesents the id of the first SaleItem that links product X to merchant Y): +--------------------------------------------------------------------+ | id | Merchant Name | Denomination | Quantity | Merchant City … -
django full text search taggit
My application - the basics I have a simple django application which allows for storing information about certain items and I'm trying to implement a search view/functionality. I'm using django-taggit to tag the items by their functionality/features. What I want to implement I want to implement a full text search which allows to search across all the fields of the items, including their tags. The problem(s) On the results view, the tagged items are showing up multiple times (one occurence per tag) The ranking is correct when I specify * only a single* tag in the search field, but when I specify multiple tag names, I will get unexpected ranking results. I suspect the SearchVector() does not resolve the tags relation as I expected it to do. The tags should be treated just like a list of words in this case. Example Code models.py from django.db import models from taggit.managers import TaggableManager class Item(models.Model): identifier = models.SlugField('ID', unique=True, editable=False) short_text = models.CharField('Short Text', max_length=100, blank=True) serial_number = models.CharField('Serial Number', max_length=30, blank=True) revision = models.CharField('Revision/Version', max_length=30, blank=True) part_number = models.CharField('Part Number', max_length=30, blank=True) manufacturer = models.CharField('Manufacturer', max_length=30, blank=True) description = models.TextField('Description', blank=True) tags = TaggableManager('Tags', blank=True) is_active = models.BooleanField('Active', default=True) forms.py … -

Issue with dictionary values not appending in Django session
I'm encountering an issue with updating dictionary values in Django session. Initially, I was using a list to store data in the session, and it worked perfectly fine. However, when I switched to using a dictionary to store the data, I noticed that the values were not getting appended as expected. Instead, the new data was replacing the old data in the dictionary. views.py: def pushups(request): if "record" not in request.session or not isinstance(request.session["record"], dict): request.session["record"] = {} return render(request, ("App_4/record.html"), { "record" : request.session["record"] }) def add(request): if request.method == 'POST': form = Add_record_form(request.POST) if form.is_valid(): a = form.cleaned_data["add_form"] b = request.session["record"] b[f"{date.year}-{date.month}-{date.day} {date.hour}:{date.minute}:{date.second}"] = a request.session["record"] = b return HttpResponseRedirect(reverse("App_4:view_record")) else: return render(request, "App_4/add_record.html", { "add_form" : form }) return render(request, ("App_4/add_record.html"), { "add_form" : Add_record_form() }) record.html {% for key,value in record.items %} <tr> <td>{{key}}</td> <td>{{value}}</td> </tr> {% empty %} <tr> <td>no tasks</td> </tr> {% endfor %} The strange thing is that the dictionary values only get updated correctly if I make changes in the views.py file or just simply click CTRL+S before adding new data. Otherwise, the previous data just gets replaced. This issue wasn't present when I was using a list instead of a dictionary. … -
Nested for loop - model.id in parent for loop does not match model.id in nested for loop (django)
I am trying to access data from a parent to a child via a foreign key. WHAT WORKS - the views The data in the child is not "ready to be used" and need to be processed, to be represented in a progress bar in %. The data processing is handled in the views. When I print it on the console, it seems to work and stored into a variable reward_positions. Reward positions = [(<Venue: Venue_name>, reward_points, reward_position_on_bar)] So this part works. The plan is therefore to access reward_position_on_bar by calling {{reward_positions.2}} WHAT DOESNT WORK - the template But something is not working to plan in the template. The template renders the last child_model (thats rewardprogram) objects of the last parent_id (thats venue) irrespective of the actual parent_id processed in the for loop. TEST RESULT & WHERE I THINK THE PROBLEM IS I think my problem lies in my nested forloop. The parent_id in the parent forloop does not match the '{{reward_position.0}}' in the nested forloop. Doing a verification test, {{key}} should be equal to {{reward_position.0}} as they both go through the same parent forloop. However, if {{key}} does change based on venue.id (parent forloop id), {{reward_position.0}} is stuck to … -

Queryset to update set of values for a field
What queryset can I use to translate the values of a field from one set of values to another set? For example, lets say I have a User model with a CharField containing the name of a country and I wish to update the name of some of the countries for all users using the following dict: new_country_names = {"Micronesia": "States of Micronesia", "Macedonia": "North Macedonia"} I obviously want to avoid doing this by looping over each user and checking the value of their country. -

Django - problem re-adding goods to the basket
I am creating an online store on Djnago. The project has a basket in which you can place goods, as well as remove them. Goods are placed and removed without problems. But, after the product has been placed, after deletion - when re-adding this product (which was deleted) to the basket (the user is always the same) - the product does not appear, what is the problem? Below is the code of all application files: models.py: from django.db import models from users.models import User class ProductCategory(models.Model): name = models.CharField(max_length=128, unique=True) description = models.TextField(null=True, blank=True) def __str__(self): return self.name class Product(models.Model): name = models.CharField(max_length=256) description = models.TextField() price = models.DecimalField(max_digits=10, decimal_places=2) quantity = models.PositiveSmallIntegerField(default=0) image = models.ImageField(upload_to='products_images') category = models.ForeignKey(to=ProductCategory, on_delete=models.CASCADE) def __str__(self): return f'Product: {self.name} | Category: {self.category.name}' class Basket(models.Model): user = models.ForeignKey(to=User, on_delete=models.CASCADE) product = models.ForeignKey(to=Product, on_delete=models.CASCADE) quantity = models.PositiveSmallIntegerField(default=0) created_timestamp = models.DateTimeField(auto_now_add=True) def __str__(self): return f'Корзина для {self.user.username} | Продукт: {self.product.name}' views.py: from django.shortcuts import render, HttpResponseRedirect from products.models import ProductCategory, Product, Basket from users.models import User def index(request): context = { 'title': 'Store', 'is_prom': True, } return render(request, 'products/index.html', context) def products(request): context = { 'title': 'Store - Каталог', 'products': Product.objects.all(), 'categories': ProductCategory.objects.all(), } return render(request, "products/products.html", … -
