Getting error when attempting to add items into the database
So, I am actively trying to create categories with subcategories. My current app is listings, and the idea is to create a ManyToManyField inside my Listing models. Here is my code inside models.py. from django.db import models from mptt.models import MPTTModel, TreeForeignKey class Category(MPTTModel): name = models.CharField(max_length=150, unique=True) parent = TreeForeignKey('self', on_delete=models.CASCADE, null=True, blank=True, related_name='children') class MPTTMeta: order_insertion_by = ['name'] class Blist(models.Model): name = models.CharField('Business Name', max_length=250) address = models.CharField('Address', max_length=300) city = models.CharField('City', max_length=100) zip_code = models.CharField('Zip Code', max_length=10) phone_number = models.CharField('Phone Number', max_length=20) web = models.URLField('Website') def __str__(self): return self.name But when I go into the shell to add items into the category, I'm getting errors: django.db.utils.ProgrammingError: column listings_category.name does not exist LINE 1: SELECT "listings_category"."id", "listings_category"."name",... What am I doing wrong here? -
Adding dictonary values while using HttpResponseRedirect
I want to redirect to the existing page and display a queryset which would be determined based on the values submitted via the form. The dictionary values I get from function get_context_data display correctly. The dictionary values I try and add in the post function do not display correctly. def post(self, request, *args, **kwargs): RoomBookingsForm = BookRoomsForm(request.POST or None) self.object = self.get_object() # assign the object to the view context = self.get_context_data( *args, **kwargs) context.update({'room_type_queryset': RoomType.objects.all().filter()}) print("all context values") print(context) if request.method == 'POST': return HttpResponseRedirect(self.request.path_info, context ) As well as context.update I also tried context['room_type_queryset'] = RoomType.objects.all().filter() Based on the two print statements above I got all context values {'object': <AmericanHotel: Caesars Palace>, 'americanhotel': <AmericanHotel: Caesars Palace>, 'slug': 'caesars-palace', 'view': <hotel.views.HotelDetailSlugView object at 0x00000210575117F0>, 'cart': <Cart: 5>, 'hotel_extra_photos': <QuerySet [<AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>, <AmericanHotelPhoto: Caesars Palace>]>, 'room_type': <QuerySet [<RoomType: Caesars Palace, Triple>, <RoomType: Caesars Palace, Double>]>, 'room_type_queryset': <QuerySet [<RoomType: Caesars Palace, Double>, <RoomType: Caesars Palace, Triple>]>} The results from room_type are correctly displayed in red. {% for instance in room_type %} <H1 style="color:red">{{instance}}</H1> {% endfor %} The results from … -

postgres performance is very slow with django
I made a very small web-app in django with sqllite3 and then I just connected the same app to postgres db in which I reccreated the tables using makemigrations and then now when I am using even the admin page, with just one superuser - admin - its very very slow. I tried postgresql.conf file to set the parameters - seq_page_cost = 1.0 and random_page_cost = 1.0 and restarted postgres.sql from services, but to no avail. is there anything I need to do apart from this ?? please let me know. -
Django/Foundation CSS Accordion Not Displaying Contents
When using the sample code here in my Django template, the information in the accordion-content div will not display on the screen, but inspecting the HTML shows that it exists. In my provided code I have both my dynamic version of the accordion and the sample code copy pasted to show both do not work, but that the information is seemingly loaded into the webpage. I can provide more information but I am unsure what would be relevant so I only included my HTML and a screenshot of the webpage. Is it possible Django is interfering with the Foundation CSS/JS? Base.html {% load static %} <!DOCTYPE html> <html class="no-js" lang="en"> <head> <meta charset="utf-8" /> <meta http-equiv="x-ua-compatible" content="ie=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>{% block title %}{% endblock %}</title> <link rel="stylesheet" href="{% static 'css/foundation.css' %}"> <link rel="stylesheet" href="{% static 'css/select2.css' %}"> {% block css %}{% endblock %} </head> <body> <!--Need to fix top bar--> <div class="top bar"> <div class="top-bar-left large-offset-1 medium-offset-1"> </div> <div class="top-bar-right"> <ul class="dropdown menu" data-dropdown-menu> <li class="menu-text">Reading List Website</li> {% if user.is_authenticated %} <li><a href="/logout/">Logout</a></li> {% else %} <li><a href="/login/">Login</a></li> {% endif %} </ul> <ul class="menu"> {% if user.is_authenticated %} {{ user.username }} {% else %} Guest {% endif … -
"created" value of TimeStampedModel is showed diffrently
I am creating the review part in my Django project. When the new review is created, the page will show the new review without redirect(with javascript), and after the page is redirected it will show the same review from DB. but the there is some difference between the created time of new review from javascript and the other one from DB. On the template, the review from DB is showed exactly my local time. But the new review created from javascript that takes the value of "created" from the backend, is different from the same review form DB after redirect. for example, 27-November-2021-00:11 (after the new review is rendered with JS without redirect) 27-Novembre-2021-09:47 (after redirecting, the new review from DB) It seems to me maybe the first one is not applicated UTC time. but printing the value of "created", the console shows 2021-11-27 00:49:57.878138+00:00 the hours are the same as the first one but the minutes are the same as the last one... I can't understand. because these two values are from the same thing, "created" of the TimeStamped Model. How could I make this value the same? models.py class TimeStampedModel(models.Model): """TimeStampledModel Definition""" created = models.DateTimeField( auto_now_add=True ) updated … -

Put DISLIKE by removing LIKE. Django
Maybe someone can help. There is a Django project where I am trying to add a LIKE / DISLIKE function. I figured out how to add or remove LIKE / DISLIKE. But my logic has a gap in that the user can put both LIKE and DISLIKE (this is not entirely correct). Therefore, I want to make a "feint with the ears" as follows: if the user puts LIKE, then changes his mind and puts DISLIKE, then DISLIKE would be added, and LIKE would be canceled automatically (as happens on YouTube). I have the following views: class AddLikeView (View) class RemoveLikeView (View) class AddDisLikeView (View) class RemoveDisLikeView (View) As far as I understand, I need to write some kind of logic in AddDisLikeView and RemoveLikeView. Tell me please. class AddDisLikeView(View): def post(self, request, *args, **kwargs): blog_post_id = int(request.POST.get('blog_post_id')) user_id = int(request.POST.get('user_id')) url_from = request.POST.get('url_from') user_inst = User.objects.get(id=user_id) blog_post_inst = News.objects.get(id=blog_post_id) try: blog_dislike_inst = BlogDisLikes.objects.get(blog_post=blog_post_inst, liked_by=user_inst) except Exception as e: blog_dislike = BlogDisLikes(blog_post=blog_post_inst, disliked_by=user_inst, dislike=True) blog_dislike.save() return redirect(url_from) class RemoveLikeView(View): def post(self, request, *args, **kwargs): blog_likes_id = int(request.POST.get('blog_likes_id')) url_from = request.POST.get('url_from') blog_like = BlogLikes.objects.get(id=blog_likes_id) blog_like.delete() return redirect(url_from) -

Best way to render a sortable table from a Django Model which displays custom fields?
I want to generate a table based on selected fields from a model(decided by an algorithm), and I want to be able to sort the columns in that table. I also want the user to be able to click on a button on each row which leads to a new page generated by a key from that row (ie. "edit") I have tried django-tables2, but it seems that this would prevent me from adding the buttons and adding the algorithms I want which govern what types of fields are on display. The generation of the custom table itself is not a problem - but I can't seem to find any sources on making a sorting function. Where can I find this? -

How to map different request types to different views using the same exact path in Django?

Identity Verification by SMS/Email | Django
Please help me with choosing a solution for implementing identity verification using a one-time token with a limited lifetime. By identity verification, i mean the need to send a token/code to a user via a phone number or email. For example, to reset password. I am interested in a solution that is best for use in a modern web application. Please tell me based on your experience in developing such systems. The solutions I have on my mind: Use redis as storage. In case of working with email, generate a token and save it in redis, where the key - user's email address. In the case of working with SMS, create a code and save it in redis, where the key - user's phone number. Possible disadvantage: since redis is designed to work with a key-value pair, it is impossible to have two tokens/codes at once. (meaning that they will have different purposes). It is possible that this is not necessary at all. Use the Django object model as storage. Something like this: class TokenManager(models.Manager): # Some util-methods. # ... def delete_expired(self): expires = models.ExpressionWrapper( models.F("created_at") + models.F("lifetime"), models.DateTimeField() ) self.annotate(expires_at=expires).filter(expires_at__lte=now()).delete() class Token(models.Model): # Roughly speaking, token identifier. Examples: "password-reset", …
