ModuleNotFoundError: Apache, Bitnami, Django app failing to import from virtual env
I'm attempting to get a very simple Django app deployed on an AWS Lightsail instance for the first time. I provisioned an AWS Apache instance set up with bitnami and django, and followed the tutorial without a virtual environment successfully but have since spent hours attempting to add my own project with a virtual environment. Most things seem set up correctly and I start Apache fine, only to navigate by browser to my url and find in the error logs a ModuleNotFoundError: No module named 'requests' error. This is the first import of any pip-installed module in my code and so suggests my virtual env has not made it into my PYTHONPATH. I just found a solution by hardcoding the path to my site-packages and appending it using sys.path.append(...) in my wsgi.py file, but I don't think this is the correct way to configure mod_wsgi with a django app and am worried it will lead to unexpected problems later. All django projects on the server are located at /opt/bitnami/apps/django/django-projects/. Following the tutorial, this directory contained projects "Project" and "tutorial". To separate my requirements.txt file and virtual environment env frome these projects, I decided to locate my project (a very simple … -
How do I add a polymorphic class in Django?
I am trying to make an application for a restaurant in django; I have to create a menu for different types of items, and all of those different types of items have to essentially be a product, so that I can add that product to a user's corresponding cart. Here are my menu items: from django.db import models from django.contrib.auth.models import User class Product(models.Model): price = models.DecimalField(decimal_places=2, max_digits=10) class Pizza(Product): pizzatype = models.CharField(max_length=15) extras = models.TextField(max_length=50) size = models.CharField(max_length=10) class Subs(Product): name = models.TextField(max_length=64) size = models.CharField(max_length=10) class DinnerPlatters(Product): name = models.TextField(max_length=64) size = models.CharField(max_length=10) class Pasta(Product): name = models.TextField(max_length=64) class Salads(Product): name = models.TextField(max_length=64) As can be seen, I tried deriving the models for different types of menu items from a single model Product, but while running makemigrations, I get the following message on the terminal: You are trying to add a non-nullable field 'product_ptr' to dinnerplatters without a default; we can't do that (the database needs something to populate existing rows).

Cross checking field input in Python
I am writing a web application using oTree and Django and I am totally new to both. I am willing to ask the user to compile a form with two fields on the same page. I need to have a validation that checks whether the sum of the two values inserted in the two fields is less than a maximum value (e.g. 10). If the sum is bigger, I need to raise an error not letting the user switch to the next page. That's the code in the html file relative to the user input: {% formfield player.attribute_1 label="Your attribute 1 (from 0 to 10):" %} {% formfield player.attribute_2 label="Your attribute 2 (from 0 to 10):" %} {% next_button %} And that's the relative piece of code in the models.py file: class Player(BasePlayer): attribute_1 = models.CurrencyField( min=0, max=10, doc="""Your attribute 1""" ) attribute_2 = models.CurrencyField( min=0, max=10, doc="""Your attribute 2""" ) Currently it checks each single formfield to be in the range 0-10. How can I check the sum to be less than 10 instead? Thank you very much in advance for any help. -
How can I get the kwarg of the current url in Django
I am calling a view via an async AJAX call to lazy load blog posts. Now I am searching for a solution to get the category keyword (or named) arguments (kwarg) of the current url to use it for the database query within the view. So I either have to somehow pass that category via AJAX to the view or call it in the view directly. I do neither know which solution is the better one nor how to implement them. What I have: urls urlpatterns = [ path('<category>', render_blog_category, name='HotStocks'), path('<category>', render_blog_category, name='AsiaPacific'), path('<category>', render_blog_category, name='Europe'), path('<category>', render_blog_category, name='America'), path('<category>', render_blog_category, name='Pennystocks'), path('<category>', render_blog_category, name='Charts'), url(r'^$', render_blog_main, name='render_blog'), url(r'^lazy_load_posts/$', lazy_load_posts, name='lazy_load_posts'), url(r'^lazy_load_search/$', lazy_load_search, name='lazy_load_search'), ] blog.html which extends base.html <script type="text/javascript"> // A CSRF token is required when making post requests in Django // To be used for making AJAX requests in script.js window.CSRF_TOKEN = "{{ csrf_token }}"; </script> <div id="blog-wrapper"> <!-- Latest Posts --> <div id="latest-posts-ctn"> <div id="posts">{% include 'blog/posts.html' %}</div> </div> <div id="lazyLoad-ctn"> <a id="lazyLoadLink" href="javascript:void(0);" data-page="2"><div id="loadmore-button">Load More Posts</div></a> </div> </div> <!-- Close Blog-Wrapper --> base.html <ul id="navbar-navigation"> <li class="navigation-item"> <a href="{% url 'AsiaPacific' category='Asia Pacific' %}">Asia Pacific</a> </li> <li class="navigation-item"> <a href="{% url 'Europe' category='Europe' … -

Django: Page not found (404) when posting form data
I am trying to create a form to submit a blog post on an author detail page, so that the blog post will automatically use the current author as its "blog_author" foreign key. The Django docs recommended using 1 parent view and 2 subviews to handle get and post respectively (https://docs.djangoproject.com/en/3.0/topics/class-based-views/mixins/). The page renders fine with the get, but the post gives me an error reading "Page not found (404) - no blog post found matching the query." The exception is raised by my parent view (blog.views.AuthorDetail), but there is no traceback. Here are my views: class BlogAuthorDetailView(generic.DetailView): model = BlogAuthor def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['form'] = BlogSubmitForm() return context class BlogSubmit(SingleObjectMixin, FormView): template_name = 'blogauthor_detail.html' form_class = BlogSubmitForm model = BlogPost def post(self, request, *args, **kwargs): if not request.user.is_authenticated: return HttpResponseForbidden() self.object = self.get_object() #Should I be overriding form_valid() to use the line above?

Django: Official recommendations for using try - except (aka try catch exception handling)
In Django specifically, what are the recommendations for using try/except, for example, in a view or similar area of the code? I could not find an official document on best practices & performance considerations for Django specifically. For context, if an exception is raised in a view without a try-except, the error and some trace is reported in the log and the Django server keeps running. Now, there are some times when a try-except is necessary for logic. There are other times when it's not- the best course of action is to raise it anyhow and leave the function. Technically, almost every line of code could be a try-except. In practise, that code gets very long, and rather than having 1 central way to deal with raised exceptions, it creates lots of copying and pasting across the dev team which can result in consistency issues/cat herding. What are the official recommendations, and failing that, what rules of thumb are there? FYI, using Python3. -

Return serialized JSON from DRF Serializer
I have a custom serializer that is returning a string representation of JSON. This serializer uses django.contrib.gis.serializers.geojson.Serializer which is much faster than the DRF serializer. The downside of this serializer is that it returns everything already serialized into a string, rather than as a JSON serializiable object. Is there a way to shortcut the DRF obj>json string process and just pass the string as the json response? Currently I am doing the following, but the obj>string>dict>string process is not ideal: from django.contrib.gis.serializers.geojson import Serializer from json import loads class GeoJSONFastSerializer(Serializer): def __init__(self, *args, **kwargs): self.instances = args[0] super().__init__() @property def data(self): # The use of json.loads here to deserialize the string, # only for it to be reserialized by DRF is inefficient. return loads(self.serialize(self.instances)) Which is implemented (simplified version) in the view: from rest_framework.mixins import ListModelMixin from rest_framework.viewsets import GenericViewSet class GeoJSONPlaceViewSet(ListModelMixin, GenericViewSet): serializer_class = GeoJSONFastSerializer queryset = Places.objects.all() -

How can i fix this problem? if request.method == "POST": keyword = request.POST['keyword'] if '£#$½{[]}' in keyword: print("Please enter invalid words") else: url = 'https://www.emu.edu.tr/en' contents = requests.get(url) page_html = contents.text pagesoup = bs4(page_html, 'html.parser') mykeyword = pagesoup.find_all(keyword) for output in mykeyword: if output.select('p')[0].text == '1': print(output.text) return render(request, 'BeatifulSoup.html', {} -
Do Django models tests need database usage?
Here an minimal example (full code), a foobar application with a Class Fruit whom I want to test the __str__() method. foobar.models : from django.db import models class Fruit(models.Model): """An MVC for testing models without using Django DB""" name = models.CharField(max_length=42) def __str__(self): return self.name.upper() foobar.tests from pytest import mark from foobar.models import Fruit fruit_name = "cherry" def test_fruit__str__py(): """testing Fruit.__str__() whitout using Django DB""" test_fruit = Fruit(name=fruit_name) assert test_fruit.__str__() == fruit_name.upper() @mark.django_db def test_fruit__str__dj(): """testing Fruit.__str__() using Django DB""" Fruit.objects.create(name=fruit_name) test_fruit = Fruit.objects.last() assert test_fruit.__str__() == fruit_name.upper() Question : Since the method you would test do not involve database or pre-loaded dataset and if I want to unit-test, is the first one (test_fruit__str__py()) enough relevant? -
Django collectstatic does not collect media files from react npm build folder
I have a frontend react app, after using npm run build it creates build folder with: build favicon.ico index.html service-woker.js static After using django's python manage.py collectstatic I noticed what django has done was that it pulls out only the static folder, favicon.ico is not pulled out. So, my website icon doesn't work. In my index.html, <link rel="apple-touch-icon" href="%PUBLIC_URL%/favicon.ico" /> In my settings.py STATICFILES_DIRS = [ os.path.join(BASE_DIR, '../frontend/build/static') ] STATIC_ROOT = '/var/www/web/home/static/' STATIC_URL = 'home/static/' In chrome inspect in the headers element: <link rel="icon" href="./home/favicon.ico"> How do I get it to display my web icon. Thankyou!
