PythonAnywhere image not found
Before anyone deletes this due to the question being similar to others: Neither other questions nor the documentation got my site to work as intended. The goal: Load images on my site The problem: Image not found Additional info: It works locally using python manage.py runserver What I've done to try to fix it: I've tried to follow the staticfiles guide https://help.pythonanywhere.com/pages/DjangoStaticFiles but this didn't work because I'm not using the default uploaded files handling. I've tried to enter it under the PythonAnywhere > Web > static files tab but haven't been able to get that to work. Tried a bunch of different solutions from the PythonAnywhere forum and SO forum and none got my site to work.

Open EDX lms login doesn't redirects to dashboard
Open EDX lms login doesn't redirects to dashboard, instead it goes back to homepage. Whenever I click the sign in button from any other page (like a course), it sign in perfectly, when I click the button from homepage, it returns to homepage and doesn't even show the logged in user. I think I have this code (main.html), that is sending the homepage url (or any other page when clicked from there). <%def name="login_query()">${ u"?next={next}".format( next=urlquote_plus(login_redirect_url if login_redirect_url else request.path) ) if (login_redirect_url or request) else "" }</%def> How can I make it perfect? -

P5.js and Django: Saving a soundfile to a server
I am trying to record audio through the user's microphone and then save it as a wav on the server running Django. I based my code on this: https://discourse.processing.org/t/uploading-recorded-audio-to-web-server-node-js-express/4569/4 I am getting two errors: Error: [object ReadableStream] p5.js:78248 Fetch failed loading: POST "http://localhost:8000/ajax/postRecordedAudio/".

Django/Python Dynamic Microservices

Why does Requests' Session.get() raise an requests.exceptions.ConnectionError instead of requests.exceptions.Timeout, when a timeout occurs?

Django pass a filtered query set between class based views
I have a Django class based ListView, which is filtered within its get_queryset function, using url parameters from a filter form, that returns an object_list. Now I want to export the filtered content of the ListView by using a button that calls a second class based view for exporting the list to a .csv file. Both views are not the problem, but how do I get the data from the ListView, after its filtered, to the export view. Tried something with sessions, but did not get that to work. Perhaps it is possible to hand over the filter parameters but I always ran into problems with the request.session cache, which seems not to be available, even if everything necessary is enabled in the settings. Any ideas for a good approach on this? Everything I read so far about sessions did not help especially with class based views. -
Django. Submitting form with valid data returns http 405 after submission with invalid data

Is it possible to change the management/commands directory in Django?
In Django it's possible to write custom management commands. These are stored by default in the proj/app/management/commands directory of your application. Is there a way to change this location to a custom directory? E.g. /proj/cmd/? For example, to change the migrations directory you can use the MIGRATIONS_MODULES setting. Is there an equivalent for management commands? It doesn't appear to be documented. -
Retrieve a python list from external python file(Django)
I'm trying to retrieve a python list that generates from an external python file(algorithm.py). In algorithm.py has a set of functions that used to generate a python list. There is no issue with algorithm.py file and it generates the python list as I expect. I followed the below steps to get the python list which generates in algorithm.py into views.py. 1.) Pass a variable(lec_name) from a function in views.py to algorithm.py and retrieve the output by using stdout as the below statement. lec_name = request.POST['selected_name'] result = run([sys.executable,'//Projects//altg//algorithm.py',lec_name], shell=False, stdout=PIPE) 2.) And then when I print(result.stdout), I receive the output(the python list which I expect) as an array of byte as below. b"[['0', 'Subject01(IS0001)', 'Z Hall(65)', 'Thursday 10:00-12:00'], ['1', 'Subject02(IS42255)', 'N Hall(90)', 'Wednesday 08:00-10.00']]\r\n" 3.) Then I used print((result.stdout).strip()) to remove \r\n and It gives output as below. b"[['0', 'Subject01(IS0001)', 'Z Hall(65)', 'Thursday 10:00-12:00'], ['1', 'Subject02(IS42255)', 'N Hall(90)', 'Wednesday 08:00-10.00']]" This gives the python list which I expect as an array of byte So what I need, retrieve the output(the python list which I expect) as a python list. How can I solve this? I tried lot of things, but none succeeded. I'm using Python 3.7.4, Django 3.0.1
