Serving static files with NGINX and DJANGO
I'm new to programming and I've managed to build my father a website where he can showcase his photography, I recently had to switch from shared hosting to my own VPS that uses ubuntu to give me more control and access to latest pips. I've had everything working on local server regarding static files, everything uploads where it is meant to(for me it was static/media). In production I've got my website running perfectly other than any css working for my templates or even admin panel and images not showing. I have ran the following commands to get where I am, I will so share some code and screenshots of current configuration also.

Is django data migration immediately applied?
I read the following text on docs: """ Django’s default behavior is to run in autocommit mode. Each query is immediately committed to the database, unless a transaction is active. See below for details. """ and I'm running the following data migration: def fill_query(apps, schema_editor): Result = apps.get_model('monitoring', 'Result') for r in Result.objects.all(): r.query = r.monitored_search.query r.user_id = r.monitored_search.user_id r.save() class Migration(migrations.Migration): dependencies = [ ('monitoring', '0006_searchresult_user_id'), ] operations = [ migrations.RunPython(fill_query), ] But when I try to find objects from Result I found that all still have query and user_id as null. And my data migration keep running (more than 2 millions registers on database) maybe the changes will be applied when data migration stop running or my data migration is not working? -

How to create a statefull Django API server?
I'm creating an API using Django, which receives an image, analyzes it using some AI models, and returns the result. The models are pretty heavy, so I want to load them only once on the application start and keep them in the memory. The models are encapsulated in a class, so my idea is to create a global object being an instance of this class and use it inside of the view. Is it the way to go? If so, where to keep this object? The only possibility that comes to my mind is the views.py file. What is the best way to achieve this? Thanks in advance! -

'psycopg2.errors.UndefinedTable: relation "table" does not exist' when makemigrations
I have a django app and I am trying to migrate from sqlite3 to postgres.

How to speed-up (avoid) django boot time when running tests?
When I write django tests, I frequently run then manage.py tests command. To increase test run performance I'm aware of --keepdb and --parallel options. I'm also aware of being able to run a specific test by targeting it. I usually run something like this : manage.py tests myapp.tests.test_file.MyTestCase.test_my_test --keepdb The problem is that each time I run the command, django took few seconds (around 10 seconds in the current project) just to boot-up and start processing the tests. So during a test development I have to wait 10 seconds each time whereas the test itself took 1 second. There is a way to enter a sort of "test mode" which keep django booted-up ? So that I can run tests without to wait for 10 seconds boot time after each code modification. -

passing django variables as parameters into href url
On my home page i want to have 3 links that will redirect the user to a page ('127.0.0.1:8000/person/<str:name>') which will display the name that they clicked. I would like to use a for loop to create links for these names as i plan to have much more than 3 names. I have tested with the two methods (for loop / manually writing out all of the links) but can't get the for loop to work. I thought these two methods below would produce the same result. <h2>does not work</h2> {% for person in people %} <a href="{% url 'person' '{{person}}' %}">{{person}}</a> {% endfor %} <h2>works</h2> <a href="{% url 'person' 'logan' %}">logan</a> <a href="{% url 'person' 'paul' %}">paul</a> <a href="{% url 'person' 'nicola' %}">nicola</a> What the urls look like in page source: views.py def home(request): return render(request, "APP/home.html", context={"people":['logan', 'paul', 'nicola']}) def person(request, name): return render(request, 'APP/person.html', context={"name":name}) urls.py urlpatterns = [ path('home/', views.home, name='home'), path('person/<str:name>/', views.person, name='person'), ] -
