RingCentral OAuth with Django
I'm working through RingCentral's Authorization Flow Quick Start App using Django. This required making a few changes to the Flask code provided, but most of the flow is working. The index page sends me to RingCentral login, which then sends me back to the test page as it should. But when I click on any of the three links on that page I get the same error: AttributeError at /test/ 'bytes' object has no attribute 'get' Here's the Django view that handles the test page (slightly modified from the Flask code provided): def test(request): platform = SyncConfig.rcsdk.platform() platform.auth().set_data(request.session['sessionAccessToken']) if platform.logged_in() == False: return index(request) api = request.GET.get('api') if api == "extension": resp = platform.get("/restapi/v1.0/account/~/extension") return resp.response()._content elif api == "extension-call-log": resp = platform.get("/restapi/v1.0/account/~/extension/~/call-log") return resp.response()._content elif api == "account-call-log": resp = platform.get("/restapi/v1.0/account/~/call-log") return resp.response()._content else: return render(request, 'sync/test.html') And sync/test.html <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> </head> <body> <b><a href="/logout">Logout</a></b> <h2>Call APIs</h2> <ul> <li><a href="/test?api=extension">Read Extension Info</a></li> <li><a href="/test?api=extension-call-log">Read Extension Call Log</a></li> <li><a href="/test?api=account-call-log">Read Account Call Log</a></li> </ul> </body> </html> Has anyone setup a Django authorization flow for RingCentral and can show me where this is breaking? -

Automatically populating HTML attributes with Django for-loop
I am making a website using Django and Wagtail CMS, and have a way of filtering posts by a custom attribute called "data-group" in the html template. It works when I hard-code everything, but I would like to use some logic to have that attribute filled dynamically for each post. Basically, I want the post tags to be populated there, but I am having a problem doing this. I will highlight relevant lines of the code with -------------------------- An example of hard-coded filter buttons: <ul class="portfolio-filters"> <li class="active"> <a class="filter btn btn-sm btn-link" data-group="category_all">All</a> </li> <li> <a class="filter btn btn-sm btn-link" data group="category_detailed">Detailed</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_direct-url">Direct URL</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_image">Image</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_soundcloud">SoundCloud</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_video">Video</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_vimeo-video">Vimeo Video</a> </li> <li> <a class="filter btn btn-sm btn-link" data-group="category_youtube-video">YouTube Video</a> </li> </ul> When any of the above buttons are clicked, it filters posts/items with similar values in the data-group attribute. An example of the items it is filtering are below in the figure data-groups list: --------------------------<figure class="item standard" data-groups='["category_all", "category_detailed"]'> -------------------------- <div class="item"> <div class="blog-card"> <div … -
Dockerizing Django & Gunicorn - Docker-compose up error - env vars not set

inlineformsetfactory validate_min validate other form than first
I want to write a form that contains a question and at least 2 answer choices. A user should provide at least 2 choices for the question to validate. To do that I am using inlineformsetfactory with the kwargs: { ... 'min_num': 2, 'validate_min': True, 'max_num': 20, 'validate_max': True, 'extra': 2 } The problem I am facing is: Django does not look if 2 answers are given but rather if answer[0] and answer[1] are filled. This is what I see upon submitting my form. Possible duplicate of this post - that unfortunately does not have an answer either. It seems that Djangos method of checking out-of-order forms does not really exist. In case that you are wondering why I don't provide my full inlineformsetfactory - I use a the extra-views package that allows for class based InlineFormSetFactory but works just like the normal django function. -
Why am I obtaining this error message trying to migrate a Django application from SQL Lite DB to Postgres DB?
I am pretty new in Django and Python and I am trying to follow this videotutorial about how to migrate a Django application from SqlLite to Postgres database: https://www.youtube.com/watch?v=lR4N4rhGdjo But I am finding some problem. Following the details on what I have done: I am working on Ubuntu 20.04 and I have a Django application made by someone else that uses SQLLite and that have to be migrated on Postgres. Following the previous tutorial I have done the following steps: First of all I installed Postegres and PgAdmin4 on my Ubuntu system. Then I created a DB named dgsrgdb that have to be my new database for my application: It have defined 2 users: one is the "root" user and the other one an user that can operate only on this specific DB. I installed this package to let Python\Django operate with Postgres: pip3 install psycopg2-binary I performed the backup of my original SqlLite DB by this command: python3 manage.py dumpdata > datadump.json and I obtained the datadumo.json file that should contains the data inside the original DB that have to moved on the new Postgres DB. Into the Django settings.py file I replaced this configuration: DATABASES = { 'default': … -

destroyable server for dev integration
A little background: In my company we develop multiple features in parallel and test each feature individually. So typically what happens is: - Multiple backend devs work on a feature by the time frontend devs work on some feature. - Stagings are busy for testing and UAT of previous features. - Its not advisable to use stagings for integration and dev testing. - Backend is micro-service architecture mostly in python (Django) which requires migrations and two features can not be merged every time on stagings. - Frontend devs need to wait for staging to be free for integration and dev testing which delays productivity. - Having more stagings will not fix the issue since there are many developers waiting in the queue. - Dev testing and integration can take more than a day. - Using Ngrok has a issue, backend dev will be blocked and can not change branches for next feature. Any suggestions how we can be more productive and tackle this issue? -

DJANGO: is there any kind of limit with the post requests?
I'm developing an app which you upload an excel file with a lot of rows(could be 10.000 or more rows) and it has to process all those rows. That means that I have to ask through ajax for some data per row. The thing is that when I try this with a big file (arround 5000 rows) it just stops after a lot of requests and doesnt give me any clue, no errors, no warning, nothing.

django_filters: How to make DateTimeFromToRangeFilter inline fields?
I have two questions: I am using django_filters and the field DateTimeFromToRangeFilter. This field appears like two fields aligned vertically (see picture). How can i make this fields display inline? I also would like to add a text before of every field. Is there a way to do this in django? Thank you.
