Create a dynamic form (not only in number of items but structure) in Django
I am new to django and I am struggling to develop the following. I have a survey app in which an admin user can provide to create a new survey template a CSV with a variable number of questions and answers per question, wich may be True or False indistinctly. This is stored using these three different models: class Survey(models.Model): survey_name = models.CharField(max_length=50, unique=True) answer_key = models.CharField(max_length=250) score_key = models.CharField(max_length=250) date = models.DateTimeField(auto_now_add=True) class Question(models.Model): survey = models.ForeignKey(Survey, on_delete=models.CASCADE) text = models.CharField(max_length=250) class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) text = models.CharField(max_length=250) valid = models.BooleanField(default=False) I know how to retrieve the associated objects for a given survey in a view and show them a template, but not how to represent them in a form, since the number of questions and answers per question are not known beforehand. Also not sure how this would be read when processing the POST. Any hint would be much appreciated. Thanks! -

Temporary MEDIA_ROOT for testing not working

how to re deploy updates to elastic bean stalk, issue with allowed hosts django
It seems like eb deploy is the solution. But notice this error: Invalid HTTP_HOST header: 'hiddenforstackoverflow'. You may need to add 'hiddenforstackoverflow' to ALLOWED_HOSTS. however, I go to my allowed hosts in my django settings.

DJANGO get objects in sql like join
Context: I'm forcing my self to learn django, I already wrote a small php based website, so I'm basically porting over the pages and functions to learn how django works. I have 2 models from django.db import models class Site(models.Model): name = models.CharField(max_length=50, unique=True) def __str__(self): return self.name class Combo(models.Model): username = models.CharField(max_length=50) password = models.CharField(max_length=50) dead = models.BooleanField(default=False) timestamp = models.DateTimeField(auto_now_add=True) siteID = models.ForeignKey(Site, on_delete=models.PROTECT) class Meta: unique_together = ('username','password','siteID') def __str__(self): return f"{self.username}:{self.password}@{self.siteID.name}" When creating a view, I want to get the Combo objects, but I want to sort them first by site name, then username. I tried to create the view, but get errors about what fields I can order by Cannot resolve keyword 'Site' into field. Choices are: dead, id, password, siteID, siteID_id, timestamp, username def current(request): current = Combo.objects.filter(dead=False).order_by('Site__name','username') return render(request, 'passwords/current.html',{'current':current}) Since I'm not necissarily entering the sites into the database in alphabetical order, ordering by siteID wouldn't be useful. Looking for some help to figure out how to return back the list of Combo objects ordered by the Site name object then the username. -
Adding new pages in Django from existing data
I am trying to simply add a new 'blog' page in Django, which should replicate the home page. The home page is working fine, and if I view the URLs for my app, it looks like the following: urlpatterns = [ path('', views.PostList.as_view(), name='home'), path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'), ] In my understanding of Django, I could add a 'blog' page by adding the following: urlpatterns = [ path('', views.PostList.as_view(), name='home'), path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'), path('blog/', views.PostList.as_view(), name='blog'), #ADDED LINE ] However going to my http://127.0.0.1:8000/blog/ page returns a 404 error. With Django debugging enabled, I get the following message: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/blog/ Raised by: main_site_app.views.PostDetail From what I can observe, there is nothing additional that the index page has that the blog doesn't. Is there a step I'm missing here that is preventing the /blog/ page from showing up? -

BS4 returning AttributeError: 'NoneType' object has no attribute 'text' sometimes, how to solve this?
I wrote a piece that tries to get some data from yahoo finance. However, first attempt it failed somewhere at the start after being able to retrieve stock data (price and change in price). It gave the NoneType error. Then I ran it again, and it actually was able to retrieve suddenly that data and continued to retrieve more and failed somewhere halfway with the same error. I find it weird, since that attribute text is present in the html. Especially weird that it is able to find it in the second attempt without adjustments. Also, it is all on the same page, so it is not that I need to wait for some. This is the error: price = soup_ticker.find('span', class_='Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)').text AttributeError: 'NoneType' object has no attribute 'text' This is the specific html: <span class="Trsdu(0.3s) Fw(b) Fz(36px) Mb(-4px) D(ib)" data-reactid="32">22.12</span> This is my Code.

Django : How to extend page slug with keep data model working? .../slug/ and .../slug/review/

What kind of class I can use in my views.py? I've tried with UpdateView but with a form which is not the main model that's does not work. -
