Using apscheduler to run Django serializer code every 15 minutes and updates it's data
using serializers I wrote some code that will ssh to different machines and return some information about these machines. Every time I refresh my page, the code will ssh to the system and return real time data. After noticing how long it takes to ssh to the machines to return data and some other issues, I figured this approach is not the best. I would like to save whatever result I git from the ssh in a database/cache and retrieve this data when I refresh the page from the database/cache. I thought of using an apscheduler and have the serializer update it's data every 15 minutes instead of every time I refresh the page (ssh once every 15 minutes). I am not sure if this will work or if there are better ways to achieve this. I would be thankful if you guys give some pointers. Currently my serializer results are not saved in the database. So to achieve this do I need to save the results of the serializer in the database? and will apscheduler do the trick? -

Getting list of context variables out of string
I have the following string in my Django app: "Hello, {{ name }}. I will arrive at {{ time }}". My goal is to come with a list of variables that is used in that string: def my_func(): # What should be done here ? my_str = "Hello, {{ name }}. I will arrive at {{ time }}" print(my_func(my_str)) # Desired output ["name", "time"] The desired output here should be ["name", "time"].

Django decorator to redirect to same page?
When a user tries to access a non permitted page, whats the right thing to do ? First option: Redirect to the same page they came from Second Option: Redirect to error page saying permission denied or not found Third Option: Redirect to login page I have created a decorator: from django.contrib.auth.decorators import user_passes_test from django.contrib.auth import REDIRECT_FIELD_NAME def is_student(function=None, redirect_field_name=REDIRECT_FIELD_NAME, login_url=None): actual_decorator = user_passes_test( lambda u: (u.is_authenticated and u.role == 'role1'), login_url=login_url, redirect_field_name=redirect_field_name ) if function: return actual_decorator(function) return actual_decorator So the above works and redirects to login if we give login_url ! How to redirect to same page from users came or which option is best ? -

why doesn't echo copy over github secret to .env file
I have a Django app that collects the secret key from a '.env' file in my local directory, I have added this .env to .gitignore so it doesn't get uploaded to github, the only problem is I have now deployed the app to AWS EC2 and I'm using github as a codepipeline, so now the app can't obtain the secret key as it doesn't have the .env file to read from. I've added my secret key to 'github secrets' which is in the repository settings , from what I've read online using echo to get the key and write to a new .env file on startup would work, only problem is the key doesn't echo over to the .env file , yet the file is created with the following command. What's going wrong, please advise on how to fix?: setup_env.sh #!/bin/bash cd /home/ubuntu/djangoapp1/djangoapp1/settings touch .env echo SECRET_KEY=${{ secrets.SECRET_KEY }} > .env appspec.yml version: 0.0 os: linux files: - source: / destination: /home/ubuntu/ hooks: BeforeInstall: - location: scripts/setup_env.sh timeout: 6000 runas: ubuntu AfterInstall: - location: scripts/install_python_dependencies.sh timeout: 6000 runas: ubuntu -

NOT NULL constraint failed error when attempting to save using createview
This is my first post to SO, so please let me know if I've missed any important details. I am working on updates to a home-grown DJango based ticketing system. I have two "parent" models (ParentProjects and Projects) that capture details about work we want to track. Both models have a number of columns that store information in the associated table as well as some FK relations. I have set up a generic class-based detail view for objects in both the Project table. The ParentProject table uses a function based view to accomplish the same task of loading the parent project details. The problem I am having is that I cannot add a new entry to the IDTasks model that automatically inserts the Parent Project id. I am able to add a new IDTask from within the admin site (or from the "client" site if I enable the "parent" field within the modelform) and then manually selecting the parent I wish to associate the IDTask to. I can also edit an existing IDTask from within the Parent Project detail template and everything saves successfully. When I attempt to add an IDTask using the createview, Django reports a Not NULL contraint … -
