get_next/prev_by after searching django
I have trouble after trying to use get_next_by_FOO/ get_previous_by_FOO after searching. For example, Search result gives 10 differences results. if I click the first, It shows information. Then I click next, it won't show the second result in 10 results, shows the next value in data.

How to add new Foreign Key objects in a Form in Django?
I have a blog that uses Django and currently I am building a page for creating new posts. In my Post model I have a Foreign Key field that is linked to a ImageField. When rendering the page using a generic class view, the field is displayed as a drop-down as expected, but I would like to add new thumbnails, not only selecting the existing ones, similar to the behavior of the admin page when there is a Foreign Key field, where: There is a plus sign next to the drop-down When clicked, shows a pop up where I can upload the image After uploading the image, return to the main page, where the new option is created in the drop-down How can I have a behavior similar to the admin's in my page? I tried to implement it as a widget, but the end result is very messy, as it just redirects to the admin page and I have to go back to my post creation page and reload to show the new option. Alternatively I could just replace the the Foreign Key drop-down with a field to upload a file, but I don't know how, as the foreign … -

Django-filter field not showing after adding lookup expressions - django-filter lib
I'm trying to implement a search field for my website, I decide to use django-filter I was able to create a search field and search the records by typing the exact record name in the search field. (default it provides exact field lookup) And it worked fine. Then I decide to add more field lookup so the search experience improves. But after adding some field lookups the search form field stopped appearing in the template. I go through the documentation couple of times and also tried to google the issue but unable to solve it. Test: By the way, hard cording the field lookups(icontains) to the queryset worked. And also the query set works fine. So here's my context processor which handles the search field(search field is in the base.html) context_processor.py from django.db.models import Prefetch from django.shortcuts import render from store.filters import ProductFilter from store.models import Product, ProductImage, Wishlist def include_search_bar(request): queryset = Product.objects.order_by('name').prefetch_related( Prefetch( 'productimage_set', ProductImage.objects.filter(place='Main Product Image'), to_attr='main_image' ), ) product_filter = ProductFilter(request.GET, queryset=queryset) products = product_filter.qs context = { 'product_filter': product_filter, 'products': products, } return context filters.py import django_filters from .models import Product class ProductFilter(django_filters.FilterSet): class Meta: model = Product fields = { 'name':['icontains'] } # fields … -

Django: use model_formfactory with @property model field
I have this Django model: # models.py class MyModel(models.model): _foo = models.CharField(max_length=200) foo_link = models.Charfield(max_length=250) @property def foo(self): return self._foo @foo.setter def foo(self, value): self._foo = value self.foo_link = "https://foobar.com/{}".format(value) I want foo to be a property, so that foo_link changes accordingly whenever I change it.

MongoDB database. Error "Select a valid choice. That choice is not one of the available choices."
I have installed MongoDB in my Django project. Because is the first time I use Mongo, I decided to try how it works and I created a simple program in order to store data ( price and quantity in my case). The project is called "exchange" and it has 2 folders: exchange and app. This is the file models.py from 'app' folder: from django.db import models from djongo.models.fields import ObjectIdField, Field from django.contrib.auth.models import User class Profile(models.Model): _id = ObjectIdField() user = models.ForeignKey(User, on_delete=models.CASCADE) class Order(models.Model): _id = ObjectIdField() profile = models.ForeignKey(Profile, on_delete=models.CASCADE) datetime = models.DateTimeField(auto_now_add=True) price = models.FloatField() quantity = models.FloatField() #ips = models.Field(default=[]) #subprofiles = models.Field(default={}) This is the file admin.py from django.contrib import admin from .models import * admin.site.register(Profile) admin.site.register(Order) This is how I set the database in the file settings.py of exchange folder DATABASES = { 'default': { 'ENGINE': 'djongo', 'NAME': 'engine', } } So after made the migrations and create the superuser, I run the server, I went in the section Admin, than in Profile, and I created a profile choosing the only option available (my superuser). At this point I created an order in the Orders section: so I chose in the "profile" field … -

Django server-side and client-side pagination with Datatables
This might sound like a stupid question so apologies in case I'm wasting your time. I have a tons or results coming from my data in my Django project. It's a table with many columns and almost 4000 rows. I am using Datatables for pagination, filtering, horizontal scrolling, sorting the columns. Client-side I am also using django-filter for querying the database. My problem is that the loading of the initial data (non filtered via django-filter) takes a lot of time. Shall I implement pagination on the client-side? If so, how does this work with Datatables? Will Datatables paginate/display only the (first page of) paginated data coming from the server-side query? Is there a way for the two to work together? Thanks. -

Django DayArchiveview is not detected in urls.py
I created several date-based views in Django, and while views for year and month function as expected, the view to display days is not detected. For instance, if I try to get http://127.0.0.1:8000/blog/archive/2021/, or http://127.0.0.1:8000/blog/archive/2021/01 the views will be displayed, http://127.0.0.1:8000/blog/archive/2021/01/07 will fail. I understand that the problem must be with urls.py configuration, but I just cannot find it in documentation. I also tried passing day_format='%d' to as_view method, without any results. urls.py from django.urls import path, re_path from blog import views app_name = 'blog' urlpatterns = [ # Example: /blog/ path('', views.PostListView.as_view(), name='index'), # Example: /blog/post/ (same as /blog/) path('post/', views.PostListView.as_view(), name='post_list'), # Example: /blog/post/django-example/ re_path(r'^post/(?P<slug>[-\w]+)/$', views.PostDetailView.as_view(), name='post_detail'), # Example: /blog/archive/ path('archive/', views.PostArchiveView.as_view(), name='post_archive'), # Example: /blog/archive/2019/ path('archive/<int:year>/', views.PostYearArchiveView.as_view(), name='post_year_archive'), # Example: /blog/archive/2019/nov/ path('archive/<int:year>/<int:month>/', views.PostMonthArchiveView.as_view(month_format='%m'), name='post_month_archive'), # Example: /blog/archive/2019/nov/10/ path('archive/<int:year>/<str:month>/<int:day>/', views.PostDayArchiveView.as_view(), name='post_day_archive'), # Example: /blog/archive/today/ path('archive/today/', views.PostTodayArchiveView.as_view(), name='post_today_archive'), ] views.py from django.shortcuts import render # Create your views here. from django.views.generic import ListView, DetailView, ArchiveIndexView, YearArchiveView, MonthArchiveView, \ DayArchiveView, TodayArchiveView from blog.models import Post class PostListView(ListView): model = Post template_name = 'blog/post_all.html' context_object_name = 'posts' paginate_by = 2 class PostDetailView(DetailView): model = Post class PostArchiveView(ArchiveIndexView): model = Post date_field = 'modify_dt' class PostYearArchiveView(YearArchiveView): model = Post date_field = 'modify_dt' … -
Django + html/css/Jinja vs Django + React
I'm trying to develop a simple neat website with a second page that has a python application. So far, I'm using Django with html/css/Jinja to make the website. The application works fine, but I'm finding simple styling things like making a nav bar and even anchoring internal links incredibly difficult. I find the combination of Jinja with CSS overly complex, and most the time things don't work for me. Definitely a case of me needing to study more into django, but I feel it shouldn't be this difficult to get simple things to work. Opinion of jinja/css aside, if I use React to cover the front end is it possible to avoid using the jinja/css combo? Should I invest my time to struggle through the css/jinja stuff, or would React knowledge be more valuable? Thanks, Sad_man
