Jwt Decode using PyJWT raises Signature verification failed
I'm running into a weird issue with decoding the jwt token in the django views. If I try jwt.decode('encoded_token', 'secret') then I see the "Signature verification failed" message. In order to escape from this issue I've set the verify flag to False: jwt.decode('eroded_token', 'secret', verify=False) This gives the decoded payload with no error but I'm trying to figure out how I can verify the token successfully without setting the verify flag to False. Any Ideas? Thanks -
django collectstatic with settings flag throws logging path error using incorrect logging path
I've recently started restructuring a project to use two scoops style configuration, with a config package, with settings inside it. Within that package, there's _base.py, development.py, staging.py and production.py. Since this is deployed as a WSGI app with Apache, I'm using a json file for environment variables, such as AWS credentials, db username/passwords and such. In short, following suggestions listed at https://medium.com/@ayarshabeer/django-best-practice-settings-file-for-multiple-environments-6d71c6966ee2 When deploying on staging, I have the wsgi app running through apache. In addition, manage.py $COMMAND is working with the --settings=config.settings.staging flag set. That is, with the exception of collectstatic. It's apparently trying to access an invalid logging path, and I can't figure out why its using that particular path which is not defined in the settings file being used. Current output of collectstatic run: (staging)ubuntu@farmer-stage:~/public_html/django/project$ ./manage.py collectstatic --help Using configuration [config.settings.staging] Using configuration [config.settings.staging] Traceback (most recent call last): File "./manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/home/ubuntu/.virtualenvs/staging/lib/python2.7/site-packages/django/core/management/__init__.py", line 354, in execute_from_command_line utility.execute() File "/home/ubuntu/.virtualenvs/staging/lib/python2.7/site-packages/django/core/management/__init__.py", line 328, in execute django.setup() File "/home/ubuntu/.virtualenvs/staging/lib/python2.7/site-packages/django/__init__.py", line 17, in setup configure_logging(settings.LOGGING_CONFIG, settings.LOGGING) File "/home/ubuntu/.virtualenvs/staging/lib/python2.7/site-packages/django/utils/log.py", line 86, in configure_logging logging_config_func(logging_settings) File "/usr/local/lib/python2.7.11/lib/python2.7/logging/config.py", line 794, in dictConfig dictConfigClass(config).configure() File "/usr/local/lib/python2.7.11/lib/python2.7/logging/config.py", line 576, in configure '%r: %s' % (name, e)) ValueError: Unable to configure … -

Problems with MongoDB and Python
Good evening guys, I need some help. I need to implement a MongoDB database as a default or secondary (if possible) in an application made in Django. Currently my Django application works with Tweepy, I need to save the captured data in the NoSQL database. I chose MongoDb, but I found several information saying that it is only possible to use with python 2.7 (my application was built in python 3.5). Is there any way to do it? I have already tried to use pymongo, mongodbengine, among others without success ... I believe that I am not doing correct. I need guidance in this process (I did not find information for newer versions of django and python, and the documentation has not been updated) -
Delete confirmation in django
I am working on a project in django. I have this part of code, when I want to delete an album, it shows Yes or No to choose, but the problem is, whatever the choice I make, it always delete the album.

Consume kafka messages from django app
I'm designing a django based web application capable of serving via Web sockets data that need to be consumed from Kafka topic. At this time, I came up with a solution splitted in two components: one component which consumes from kafka, perform some basic operations over retrieved data, and send the result to the django app using an http request. After request have been received, a message is written over a specific django channel. Is there a better architecture to address this kind of scenario? Should I enclose all the Kafka part in a "while True" loop in a celery async task? Should I spawn a new process when django starts? If so, can I still use the django signals to send the data via web socket? Thanks, Fb -

Load Content automatically in Django app
I'm working on a Django (1.10 & Python3) project in which I need to implement a logic as: We have articles from various categories, the user needs to tag these articles, mean when user read articles then he needs to provide his feedback rather it's relevant or irrelevant to his situation. We have to provide user's a list of categories when user select a category then all of the articles from that particular category will be available one by one to the user, mean it will show the first article to the user, when he tagged this article it will load next article automatically and also keep the user's tagging info because it's not necessary to tag all articles at once, user can tag few at a time when he can start from where has was stopped again. In simple: Would it be possible to send the user straight from their choice of a Category to the "Article Tagging" page with the next article to be tagged automatically loaded up and ready to be tagged, and the system keeps track of what the next article is that needs to be tagged?
