Setting DB index on Redis Django
I am using Redis as my caching server on Heroku, Django. However, when I page loads I get and error: redis.exceptions.ResponseError: invalid DB index My Redis setting is: CACHES = { 'default': { 'BACKEND': "redis_cache.RedisCache", 'LOCATION': os.environ.get('REDISTOGO_URL', 'redis://127.0.0.1:6379'), "OPTIONS": { "CLIENT_CLASS": "redis_cache.client.DefaultClient", } } } Shouldn't the DB index be 0 by default?

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? Since I have now gettings an error: allauth.socialaccount.models.SocialApp.DoesNotExist: SocialApp matching query does not exist. and I get a 500 internal server error when I visit: http://www.example.com/accounts/google/login/ Is the root enough to be added as Site? -

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? -

Multiple user types Django + React
I am currently planning out an application that I plan to build with Django (backend) and React (frontend). Where I am currently hitting a roadblock is the implementation of multiple user types. I am choosing Django as the backend for the sake of the fact that it will handle authentication, session management, etc.. I'd like to create an API to pull the information to the frontend which I will be using the django-rest-framework to do so. User types: Company - Company will fulfill orders - Company can have multiple Clients Client - Client will submit orders - Client can have multiple Company's to submit orders to There is no need for users to switch between accounts, and I would like to do away with the the default username and implement email to login/register. Thanks for your input
