Python: Django/Flask/ Casino/Payment [closed]
One wants to build casino, but one wants to figure out what one needs to know to do the most essential thing of it, knowing how to make real money convert to the 'points' or 'markers', and perhaps some ranking visuals of the top players or most returning costumers is fine too, so one need to know this, and one wondering what one should look into? what areas, and topics? Perhaps need to better my knowledge in some areas, and such, but one is dedicated to this project, perhaps need to develop some software in tkinter. One is at the moment concidering using django but maybe flask would be more suited for it from, web developments stand point? Django always feel as a superhighway, perhaps more advanced projects is better to do in flask? -

Cannot install pip package dependencies cloned from a GitHub repo into a separate virtualenv
I have forked and cloned a private Django GitHub repo of a friend of mine into my local directory. Since I am using Windows 8 and my friend created the repo using Linux(Ubuntu), I couldn't use his virtual env. So, I created a separate virtual environment using virtualenv(16.7.8) in my local directory. However, when I run pip install -r requirements.txt only some packages gets installed and others give error. So I had to install all the required packages by manually typing with their specific versions. However, I am unable to install two particular dependencies viz. django-compressor and rcssmin. When I ran pip install django-compressor==2.4 It "failed to build wheel for rcssmin" and logged an error on the terminal that reads error: Microsoft Visual C++ 14.0 is required .... The full error log is shown below: How do I solve this? Also, is there an alternative and better way to work on GitHub projects like this where I have to involve different OS(without using virtual machines to match OS)? -

Django : how to display images from database in template?
Hi I don't know why but I can't display images from my database. I think it is because of my path in my template.

Test case written for url resolver using resolve() in django application not working

Autlib vs OAuthlib: Are these libraries the same?
I am a beginner in the world of the OAuth2.0 and OpenID Protocols. I would like to implement a custom server - provider for multiple applications. So, to use it for Single Sign-On (SSO). I would like to work with python. Till now I have found four packages, for an OAuth2.0 and an OpenID Connect server implementation, in Python: pyoidc, django-oidc-provider, Django OAuth Toolkit (DOT) by OAuthlib and Authlib. I tried to read and understand pyoidc, but it was not so helpful and easy, basic things were missing. I have tried django-oidc-provider and I was really satisfied, and the whole implementation was really easy. So, after those trials, I am left with Django OAuth Toolkit (by OAuthlib) and Authlib. Has anyone tried them? Are these packages the same? Is Authlib an updated version of the OAuthlib library? The only information I know till now, is that Flask-OAuthlib is deprecated, and Authlib is was its new version. *Every answer or advice or personal experience would be really helpful and always appreciated! Thank you again for your help. -

Django count sub-objects with ntext on SQL Server
I have a Claim object with ClaimAttachment with a simple foreign key. I want to filter Claims that have more than x attachments. Normally, I would just do: Claim.objects.annotate(att_count=Count("attachments")).filter(att_count__gt=5) Easy. Except that Claim has several ntext fields and that results in: django.db.utils.ProgrammingError: ('42000', '[42000] [Microsoft][ODBC Driver 17 for SQL Server][SQL Server]The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator. (306) (SQLExecDirectW)') That is because Django is making an outer join between Claim and ClaimAttachment and is grouping on all fields from Claim. Several of those fields being ntext, they can't be grouped by. I tried to work around the issue by doing a subquery myself: att = ClaimAttachment.objects.filter(claim_id=OuterRef("id")).aggregate(count=Count("id")) Claim.objects.annotate(att_count=Subquery(att)).filter(att_count__gt=5) But the aggregate cannot be done on the OutRef query. I can move the Count to the annotate(att_count=Count(Subquery(att))) but I'm back to square one because it's trying to group by all fields again. I know that this is not really Django's fault but rather another SQL Server annoyance but I don't control this data model, let alone the database server setup. How can I work around this limitation and get my attachment count ? -

Authentication bypassing using browser cookies in Django UI
I have a view in Django which renders html page. I need to do authentication before rendering the page. The link to open this page would be provided in another application built using groovy. On clicking the link, the UI should be rendered directly without any login page. At present I am using the @login_required decorator which opens the login page before rendering the UI. I want to bypass or use another mechanism which would do the authentication without showing the login page. PS: I don't have much knowledge regarding authentication. -
