When deploying Django to Heroku: ModuleNotFoundError: No module named 'dotenv'
When deploying Django to Heroku, I get a ModuleNotFoundError: No module named 'dotenv' error. However, I do have python-dotenv listed in my requirements.txt. So I'm very confused about why Heroku is not happy about dotenv.

Is it possible in Wagtail to use a proxy model with RoutablePageMixin?
My Wagtail site has certain items viewable in a gallery app, that the user can edit so that it would be also shown as an item in the shop app. It's strictly one-to-one, so I don't want them to be managing the items separately. I thought proxy models might be the best way to achieve this but I'm getting stuck and not finding very much documentation about using proxy models with Wagtail. Also possibly my regex is bad. In app 'gallery': class GalleryItem(Page): parent_page_types = ['InstallationPage'] description = models.CharField(blank=True, max_length=250) direct_sale = models.BooleanField("Direct Sale", default=False, help_text="Check this box to list this item for sale directly on your website.") direct_sale_price = models.DecimalField("Sale price, $", blank=True, null=True, max_digits=6, decimal_places=2, help_text="Add more info about this item for the store page only.") direct_sale_extra_description = models.CharField("Addtional sale description (optional)", blank=True, max_length=250, ) stock = models.IntegerField("Number in stock", blank=True, null=True,) In app 'shop': from gallery.models import GalleryImage class Shop(Page): def get_context(self, request): context = super().get_context(request) shop_items = ShopItem.objects.filter(Q(direct_sale=True) | Q(external_sale=True)) paginator = Paginator(shop_items, 24) page = request.GET.get('page') try: pagin = paginator.get_page(page) except PageNotAnInteger: pagin = paginator.get_page(1) context['shop_items'] = shop_items return context class ShopItem(GalleryItem, RoutablePageMixin): class Meta: proxy = True parent_page_types = ['Shop'] @route(r"^shop/(?P<item_slug>[-\w]*)/$", name="item_view") def item_view(self, … -

Auto refering nesting with Django Rest Framework
I have this model in Django (based on a legacy database): class NationalTest(models.Model): unityId = models.IntegerField(primary_key=True) parentId = models.IntegerField(blank=True) grade = models.FloatField(blank=True) This model stores the grade that a "unity" (a school, a city, a region or a state in our country) received in a national test. unityId is the id of the unity, grade is its grade in the test, and parentId is the id of its upper parent (i.e.: if our unity is a school, parentId the id of the city where the school is located; if it's a city, parentId is the id of the state where the city is located, and so on). For front-end purposes, when I fetch some school's grade, I need also the grade of the city, the state, the region and the whole country (all 5 levels possible). When I fetch a city's grade I need state, region and country's grade too. When I fetch state's grade, just need the two levels above grade. I think that the best way I can solve it is to create a nested serializer based on parentId. I know how to do it when we have a foreign key from another model, but how can I … -

Where to define methods unrelated to models in Django project
Is there a convention related to where to define methods unrelated to models in Django? For example, I am developing a dictionary project in which I have a dictionary app as well as a tags app. From one of the views, I needed a method to collect all Tags from multiple Definitions. This method can not be implemented in any of my models.pys. Where should I define such a method? If I need to create a new file, what should I call it? Should it go in the project's folder, the dictionary app's folder, or in the tags app's folders? -

Discuss Implementation For Marketplace Website In Django
I am building a marketplace website for old mobile phones. I will be building it using django stack. I have figured out the other modules, but am stuck with payment integration for the website.(since I am quite Noob in payments field) I read about PayPal & Stripe integrations in django, but am little doubtful on how to implement these services for my website scenario. Here's the scenario:- Website will have Buyers & Sellers. Buyers - who will buy mobile phones. Sellers - who want to sell mobile phones. Each seller - will have payment details to receive payments (these can be either a paypal ID/ stripe ID) Buyers will need to checkout throut debit cards, credit cards, paypal, stripe etc. (To buy the phones) After a transaction is done, Being a marketplace, we will keep a little service fee in (℅) and handover the rest of amount to seller. Please suggest an approach to implement this scenario. -

Adding Google allauth on Django live app deployed on Heroku
I am trying to add Google authentication to my live Django app deployed on Heroku. I have added www.example.com and example.com as Site objects and have added them to the list of Sites on the Social Application object in the admin interface on Heroku. However, now that I have both the root(example.com) and subdomain www I cannot add both Site id's in my settings. How can I set the Site id properly in the settings?

How to create users and groups migrations in Django?
So I've got an API built in Django with Django Rest Framework and I now want to add a role based access control to it. For this I found the django-rest-framework-roles extension. I've got it installed, but I'm not really familiar with the usual authentication system in Django. It says I need to define the groups in the settings as ROLE_GROUPS = [group.name.lower() for group in Group.objects.all()] So I need the Group model and of course also the User model. As far as I understand, these are standard models. However, I don't have any tables in my DB for them. So I need a migration for it, but I'm unsure how I can do that. I guess it should be really easy, but even on the relevant pages in the documentation I don't see any mention on how to add these models to my Django installation. Could anybody enlighten me on this? -

ModelChoiceField in Django is not rendered
I'm desperately looking for a solution to following problem: I got a very simple form with one model choice field: from django import forms from django.contrib.auth.models import User class MyForm(forms.Form): my_field = forms.ModelChoiceField(queryset=User.objects.filter(is_superuser=False),widget=forms.Select()) The form is passed to a view and HTML file: <form method = "GET"> {{ form }} <input type = "submit" value = "Submit"> </form> The rendered HTML looks exactly as expected: <form method="GET"> <label for="id_my_field">My field:</label><select name="my_field" required="" id="id_my_field"> <option value="" selected="">---------</option> <option value="2">test1</option> <option value="3">test2</option> </select> <input type="submit" value="Submit"> </form> Still the result in the browser is not as expected: I played around with the widgets attributes for a while, but I still can not figure out why my the options are not rendered. Thanks in advance! -
Python list comprehension Django objects
I am developing a dictionary Django app where Definitions have Tags. I have written this generic function to collect all Tags from a list of Definitions. This is my current working version: def get_tags(definitions): tags = [] for d in definitions: tags += d.tags.all() return tags I was trying to accomplish the same using Python's list comprehension: tags = [] return [tags.extend(d.tags.all()) for d in definitions] This code however does not work yet. What am I missing? Is there an even slicker way to do this in just one line without creating the tags variable, perhaps using yield statement? -
