AWS S3 has to load before I execute anything on the command line
I have a django project integrated with s3, and everytime I want to execute something on the command line, e.g. python manage.py migrate, the terminal has to load this first: BEGIN REQUEST++++++++++++++++++++++++++++++++++++ Request URL = https://ec2.amazonaws.com?Action=DescribeRegions&Version=2013-10-15 RESPONSE++++++++++++++++++++++++++++++++++++ Response code: 200 <?xml version="1.0" encoding="UTF-8"?> <DescribeRegionsResponse xmlns="http://ec2.amazonaws.com/doc/2013-10-15/"> <requestId>936a670c-3q31-33kc-8713-1d0gbe6ad222</requestId> <regionInfo> <item> <regionName>ap-south-1</regionName> <regionEndpoint>ec2.ap-south-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>eu-west-3</regionName> <regionEndpoint>ec2.eu-west-3.amazonaws.com</regionEndpoint> </item> <item> <regionName>eu-west-2</regionName> <regionEndpoint>ec2.eu-west-2.amazonaws.com</regionEndpoint> </item> <item> <regionName>eu-west-1</regionName> <regionEndpoint>ec2.eu-west-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>ap-northeast-2</regionName> <regionEndpoint>ec2.ap-northeast-2.amazonaws.com</regionEndpoint> </item> <item> <regionName>ap-northeast-1</regionName> <regionEndpoint>ec2.ap-northeast-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>sa-east-1</regionName> <regionEndpoint>ec2.sa-east-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>ca-central-1</regionName> <regionEndpoint>ec2.ca-central-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>ap-southeast-1</regionName> <regionEndpoint>ec2.ap-southeast-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>ap-southeast-2</regionName> <regionEndpoint>ec2.ap-southeast-2.amazonaws.com</regionEndpoint> </item> <item> <regionName>eu-central-1</regionName> <regionEndpoint>ec2.eu-central-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>us-east-1</regionName> <regionEndpoint>ec2.us-east-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>us-east-2</regionName> <regionEndpoint>ec2.us-east-2.amazonaws.com</regionEndpoint> </item> <item> <regionName>us-west-1</regionName> <regionEndpoint>ec2.us-west-1.amazonaws.com</regionEndpoint> </item> <item> <regionName>us-west-2</regionName> <regionEndpoint>ec2.us-west-2.amazonaws.com</regionEndpoint> </item> </regionInfo> </DescribeRegionsResponse> and this creates a few seconds delay for my command to execute. Is there any way I can prevent this from happening as it's causing delays in development. -
NoReverseMatch at /polls/top/ 'polls' is not a registered namespace
Parent app name is mysite,child app name is polls. I wrote in views.py from django.shortcuts import render from .models import Polls def top(request): data = Polls.objects.order_by('-created_at') return render(request,'index.html',{'data':data}) def detail(request): data = Polls.objects.order_by('-created_at') return render(request,'detail.html',{'data':data}) in child app's urls.py from django.conf.urls import url from django.conf import settings from django.conf.urls.static import static from . import views urlpatterns=[ url('top/', views.top, name='top'), url('detail/<int:pk>/', views.top,name='detail'), ] in parent app's urls.py from django.contrib import admin from django.conf.urls import url,include app_name = 'polls' urlpatterns = [ url('admin/', admin.site.urls), url('polls/', include('polls.urls')), ] in index.html <main> {% for item in data %} <h2>{{ item.title }}</h2> <a href="{% url 'polls:detail' item.pk %}">SHOW DETAIL </a> {% endfor %} </main> When I access top method, NoReverseMatch at /polls/top/ 'polls' is not a registered namespace error happens.I am using Django 2.0,so I think namespace cannot used.I wrote app_name ,so I really cannot understand why this error happens.How should I fix this?What is wrong in my code? -

How To add Models with OneToOneField to every of some ForeignKey Custom User Models
The following scenario: I need a Custom User Model with ForeignKey to the user model. e.g.: a User can have some Planets class UserPlanet(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) name = models.CharField(default='planet', max_length=40) For each created planet, there are other models that have a OneToOneField. e.g. a Model which contains size, color or its favorite animal, however: class PlanetValues(models.Model): user_planet = models.OneToOneField(UserPlanet, related_name='planet_values', on_delete=models.CASCADE) size = models.IntegerField(default=1000) What is the best way for a Django View to choose one of the Planet and the Informations on a template was filtered to the corresponding planet. This is a simple example, but the principle does not change. How can I handle this case? -

After deleting my database I'm still getting "ProgrammingError: column post_post.hash does not exist"
How is this possible? I did python manage.py flush which deleted the database. I also uninstalled and re-installed django. I then did makemigrations and migrate.

Editing without registration in Django
I am creating a web application where users can book seats for an event. However, no registration will be needed. The reason is that I want to avoid the registration process for the users because it's more user-friendly and the second (and more important) point is that the visitors of my web page will book for an event probably only once a year. So it just does not make sense to create an account. But the people should be able to edit their booking. My idea is the following: If someone wants to book seats for the event, they have to provide an email address. After successful form submit, I will send them an email containing a link to the edit form of the booking. That should work with an UUID that is not public. I mean that every booking contains - beside the public key - an UUID (which is not public). I will send UUID only to the creator what enabled him to edit the booking. For example: You can edit your booking at example.com/booking/(UUID)/edit in the email. It's not really a question, but I am relatively unexperienced with Django and just want to hear an opinion about … -
Why M I facing KeyError in my registration django?

Django-signal / Sqlite-trigger when the user is deleted (edit user id who left a comment)
Help with the comments. The site has comments. Accordingly, the user table is used from the standard Auth + there is a table "Comments" in SQLite: class Comments(models.Model): UserID = models.ForeignKey(User, on_delete=models.CASCADE, default=0) CommentsText = models.TextField("Комментарий") LibraryID = models.ForeignKey(Library, on_delete=models.CASCADE, default=0) # Ссылка на библиотеку AddDate = models.DateTimeField(auto_now=True) def __str__(self): return self.CommentsText Suppose a person left a few comments, and then I want to delete his profile through the admin panel. It is necessary to make sure that his comments are not erased with him, but go to a specially created user with the name "Deleted_user" and conditional id = 999. I think I need to look to the side of pre_delete. But I do not have enough examples of this method. -
Issue with getting author when posting (Django)
Sorry to bother you all but I'm having an issue I have absolutely no understanding of. This is going to be fairly long so if you don't have a large amount of time on your hands please don't hesitate to ignore this question. My issue is with a tutorial for Django. I've already completed it once, so I've been trying to put a spin on it before learning more and completely rewriting it myself. I've removed a non-essential but good for organization app from the project called pages, as well as styling the actual templates. Nothing complicated, and nothing to do with the underlying way any of their code works. Time for where the actual question comes in, however first, here is the link to: The tutorial I'm following: http://intermediatedjango.com/ I was planning to link to more, but nothing but that is really relevant. In following this tutorial I've gotten to a section where you replace a part of the code you've written in the views.py file of the posts app. That section is replacing: class PostCreateView(CreateView): model = models.Post template_name = 'post_new.html' fields = ['message', 'author'] With the following: https://pastebin.com/UE5cvaQ4 After doing this and going to the page to … -
Django order search results by usage in foreign key relation
I would like to have my search results sorted by use in a foreign key relation when searching for one of my Django models. Example: Model "Tag" -> Many to Many <- Model "Post" If I am searching for a tag, I would like to get the query matching tags returned in the order they are used in the relation. This means the most used tag that meets the search criteria first, etc. Is that possible, if so, how? -

Is it save to retrieve data from HTML attributes and send it to server through AJAX?
In my web application, I use a lot of requests with Ajax. I retrieve information via Html attributes and send them to the server. <div id="wrapper-posts"> {% for post in all_posts %} <!-- html code here --> <button class="delete-post" data-id="{{post.id}}" type="button">Delete post</button> {% endfor %} </div> <script type="text/javascript"> $(document).on("click",".delete-post",function(){ var id = $(this).data("id"); $(this).attr("disabled",true); $.ajax({ url:"", type:"post", data:{ csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(), id:id, }, success:function(data){ $("#wrapper-posts").html($("#wrapper-posts",data)); } }); }); </script> I realize that user can easily modify the attributes with Inspect Element, and delete other post. What is the safe way to do it, or should I proceed with more parameters and not just the ID? like a data-code={{post.code}} where code is a random code, a length more than 10 chars. <button class="delete-post" data-id="{{post.id}}" data-code="{{post.code}}" type="button">Delete post</button> I really need helps to achieve that the safer way. Thank you! -

My urls.py: url(r'^(?P<slug>[-\w]+)/$', views.post_detail, name='post_detail'), url(r'^category/(?P<category_slug>[-\w]+)/$', views.list_of_post_by_category, name='list_of_post_by_category'), My views.py def list_of_post_by_category(request,category_slug): categories = Category.objects.all() post = Post.objects.filter(status='published') if category_slug: category = get_object_or_404(Category, slug=category_slug) post = post.filter(category=category) template = 'blog/category/list_of_post_by_category.html' context = {'categories': categories, 'post': post} return render(request, template, context) def list_of_post(request): post = Post.objects.filter(status="published") template = 'blog/post/list_of_post.html' context = {'post': post} return render(request, template, context) def post_detail(request, slug): post = get_object_or_404(Post, slug=slug) template = 'blog/post/post_detail.html' context = {'post': post} return render(request, template, context) -
Django 1.11 Forbidden (403) CSRF verification failed. Request aborted
I am writing a login page with Django 1.11. When I want to enter the account name and password on the page this is what I received: Forbidden (403) CSRF verification failed. Request aborted. Here is my code: from django.shortcuts import render_to_response from django.http import HttpResponse from django.contrib import auth from django.template import RequestContext def login(request): if request.user.is_authenticated(): return HttpResponseRedirect('/index/') username = request.POST.get('username', '') password = request.POST.get('password', '') user = auth.authenticate(username=username, password=password) if user is not None and user.is_active: auth.login(request, user) return HttpResponseRedirect('/index/') else: return render_to_response('login.html', context=locals()) And here is my template: <!doctype html> <body> <form action="" method="post"> <label for="username">用戶名稱:</label>{% csrf_token %} <input type="text" name="username" value="{{username}}" id="username"><br /> <label for="password">用戶密碼:</label> <input type="password" name="password" value="" id="password"><br /> <input type="submit" value="登入" /> </form> </body> -
Django template Tag not showing
I am confused about how Django template tag can be shown. I am using Django 2.0.3 and jQuery 3.3.1 I have this on a template called home.html: //home.html <script> $(".game-menu").click(function () { $(".game-menu").removeClass("active"); $(this).addClass("active") }); $("#buildings").click(function () { $("#main-content").load("{% url 'game:buildings' %}"); }); $("#overview").click(function () { $("#main-content").load("{% url 'game:overview' %}"); }); </script> <nav class="sidebar"> <ul class="nav nav-pills flex-column"> <li class="btn game-menu active" id="overview"> <a class="nav-link text-white">Übersicht</a> </li> <li class="btn game-menu" id="buildings"> <a class="nav-link text-white">Gebäude</a> </li> </ul> </nav> <!-- Page Content Holder --> <main class="text-white" id="main-content"> {% include 'game/overview.html' %} </main> including overview.html works fine as expected ( the template tag {{ planet.name }} showing on the page: //overview.html {% load static %} <div class="card"> <h2 class="card-header bg-dark">Übersicht - {{ planet.name }}</h2> <div class="card-body"> <h5 class="card-title">Special title treatment</h5> <p class="card-text">With supporting text below as a natural lead-in to additional content.</p> <a href="#" class="btn btn-primary">Go somewhere</a> </div> </div> now the part that confuses me if I click on the nav button overview to load the overview.html via jQuery into <main id=main-content></main> the template was shown, but the template tag {{ planet.name }} will not be shown.
