Accessing different `pk` values in Django
How do I show just a certain pk value of my sqlite database in django? I have a database that has a bunch of entries. I am currently accessing them through a DetailedView and they are all showing up nicely on the screen. i have called the entries post and i have given them title and body elements, which are just of type TextField() home.html {% block content %} {% for post in object_list %} <div class="post-entry"> <h2> <a href="{% url 'post_detail' post.pk %}">{{ post.title }}</a> </h2> <p>{{ post.body }}</p> </div> {% endfor %} {% endblock content %} What I now want to do is to place the 10th Database entry in the footer of my Home.html. So obviously this databases pk value is 10. i am just having trouble accessing this 10th value. I have tried {{ post.pk.10 }} but that doesn't work. What am i missing in order to access only the 10th value? -
How is the flow of interpretation(python interpreter) in this block of code?
def product_create_view(request): form = ProductForm(request.POST or None) if form.is_valid(): form.save() form = ProductForm() context = {'form': form} return render(request, "product_create.html", context) This is a part of the views.py file.I was thinking, about what happens first, is the html file reached out and the view rendered, and then the validation etc takes place?Or the interpreter first goes through the block of code(validation,etc) and then, it renders the html file If it is the second case(Which it seems to be, since the block of code is written first), how does the interpreter know what the form looks like, without reaching out to the html file?(Or does it not need to? and does something else?) -

Django model to save a stock portfolio to db
I'm trying to build a financial app in Django. The goal of the app is: A user will have the ability to save a portfolio to the database, and the app will run different types of financial metrics on the data, as standard deviation, beta, alpha, ect.. The issue I'm facing is that the number of stocks a user has in their portfolio is different for each user. A user who is a risk-averse investor would maybe have ten stocks, while an investor who is trading in the short term might only have 2-3 stocks in the portfolio. Each transaction consists of 5 elements: the direction the user has traded, either "long" or "short." The ticker, volume of the trade, price paid, and the transaction date. So, for example, a user has three stocks the transactions would look something like this: Transaction example How can I give the user the ability to choose how many stocks they would like to record in the portfolio? My code: Models.py from django.db import models from django.contrib.auth.models import User from django.conf import settings class Portfolio(models.Model): direction_option = ( ('Long','Long'), ('Short','Short') ) portfolio_name = models.CharField(max_length=200) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=True) direction = models.CharField(max_length=200, null=True, … -

Pagination on queryset on only a segment of the page and not the whole page
I have a page with projects for a specific category that begins with the top-x most earned projects, followed by the top-x most viewed and the third segment contains all (other) projects for this category. This third segment is long as it contains all projects for this specific category. Therefore, I would like to paginate them. But with standard pagination going to the next page will refresh the page, ending on the top of the page, needing to scroll down again to the third section (every single time you select the next page), which isn't very user friendly. I saw a site (kickstarter) where they were able to paginate only one segment of the page, leaving the other parts of the site untouched, which is exactly what I want. But I am a novice and I have no idea how to do this. Thanks for any ideas and help!

Page not found (404 error) on Django HttpResponseRedirect
I see that there are numerous posts related to HttpResponseRedirect errors(Django form redirect using HttpResponseRedirect, Django: HttpResponseRedirect not working, How can I redirect to a Thank you for contacting us page after user submits a form with Django?), and the explanations all make sense. Unfortunately, they have not helped me address my problem -- which I think/hope is more about looking at this too long and I can no longer see the forest for the trees. I am working off of this example (https://techwithtim.net/tutorials/django/simple-forms/). I have a couple of models that have been incorporated into forms.py, views.py, and urls.py but the redirect is not functioning as expected. The short of it is that I have two forms, when the first form is correctly submitted, it should got to the next form (url). Once that is correctly submitted, it should go to a thank you page. The first form is displayed at http://localhost:8000/packages/new_developer/ and should go to http://localhost:8000/packages/add_package/', but is going to http://localhost:8000/add_package/' instead. Although the information is being captured and placed in the db, I have been unsuccessful at getting a redirect. I have tried changing/removing slashes as well as moving files to different locations -- all to no avail. … -
