Django’s command-line utility | manage.py: command not found

Displaying / Testing outputs are correct. Sanity Check
I am still learning Django and slowly improving but I have a few questions, I have my whole model below: from django.db import models from datetime import datetime, timedelta # Create your models here. year_choice = [ ('year1','1-Year'), ('year3','3-Year') ] weeksinyear = 52 hours = 6.5 current_year = datetime.year class AdminData(models.Model): year1 = models.IntegerField() year3 = models.IntegerField() @property def day_rate_year1(self): return self.year1 / weeksinyear / hours class Price(models.Model): name = models.CharField(max_length=100) contract = models.CharField(max_length=5, choices=year_choice) start_date = models.DateField(default=datetime.now) end_date = models.DateField(default=datetime(2021,3,31)) def __str__(self): return self.name The main concern for me at the moment is trying to understand if my function def day_rate_year1(self): is working correctly, if someone could point me in the right direction to understand either how I display this as a string value in a template or test in the shell to see if the value pulls through as the values for year1 and year3 can change based on user input. I am trying to work out the day rate so I can then use the start and end dates and work out the number of days between the two to calculate a price which is then displayed to the user which can again change depending on the … -

How can I record form responses in Django
I'm attempting to record an answer to a basic y/n question and send it from HTML to a Django view. This is my html code: form.html <form method="POST"> {% csrf_token %} <div id="drinks"> <a class="prev" onclick="plusSlides(-1)">&#10094;</a> <a class="next" onclick="plusSlides(1)">&#10095;</a> <label> <div class="mySlides" style="display: block;"> <img src="{{ prof_pic }}" alt="image alt text" width="100" height="100"/> <div> <select name="dance_or_no" required> <option value = "" disabled="disabled" selected="selected">Ques.</option> <option value = "yes">Yes :)</option> <option value = "no">No :(</option> </select> </div> </div> </label> </div> <input type="submit" value="Submit" class="drink-it"> </form> Once the user submits this form it gets sent to auth in views.py def auth(request): if request.method == 'POST': dance_or_no = request.POST.get('dance_or_no', False) request.session['dance_or_no'] = dance_or_no print('authenticated!!') return redirect(client.generate_auth_url()) def callback(request): dance_or_no = request.session.get('dance_or_no) This route authenticates the user, which is mandatory for the website to work. So the form answers are also directed here. I am attempting to record the answer and create a session cookie to send to another view. But this dance_or_no value always gets a None value. I have done this in flask. And it worked this way, but now when I'm migrating to Django I can't seem to understand the way one can save an option form and send it from one … -
Django/PostgreSQL Project unable to run due to 'missing' libssl file
I'm trying to set up a local version of a web project made with Django and PostgreSQL. However, when I'm trying to 'run' it (makemigrations, runserver..) I get the following errors: ImportError: dlopen(/Users/my_username/Library/Python/3.8/lib/python/site-packages/psycopg2/_psycopg.cpython-38-darwin.so, 2): Library not loaded: libssl.1.1.dylib Referenced from: /Users/my_username/Library/Python/3.8/lib/python/site-packages/psycopg2/_psycopg.cpython-38-darwin.so Reason: image not found During handling of the above exception, another exception occurred: raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e) django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: dlopen(/Users/quentinbackaert/Library/Python/3.8/lib/python/site-packages/psycopg2/_psycopg.cpython-38-darwin.so, 2): Library not loaded: libssl.1.1.dylib Referenced from: /Users/quentinbackaert/Library/Python/3.8/lib/python/site-packages/psycopg2/_psycopg.cpython-38-darwin.so Reason: image not found I haven't included the full Traceback for readability reasons, but if needed I'll include it.
