Why i can't get variable name from Django
I have a Django project that i'm working on. I need to print something to CLI to make it easier to debug. This is what i need print('============================================') print('VARIABLE_NAME_IN_CAPS') print(variable) print(f'LENGTH : {len(variable)}') print('============================================') this is my function to get variable name. This is where i got the snippet def get_variable_name(variable): globals_dict = globals() return [var_name for var_name in globals_dict if globals_dict[var_name] is variable] But when i called the function i get empty array []. I've tried to do it without function and do a separate test in another file and it worked. Is there anything that prevent this to happen in Django ? -

Python Jsonschema validation returning error on correct input

I'm using a Key-Value model to make static template's data dynamic.

Django Create a copy of a Model upon trigger
I'm wondering if the following is possible in Django. As I start my the project, I will create a Model with 'x' fields called BASEMODEL. I will then create another Model called PROJECT with just 1 CharField. I will be creating both these in the usual way models.py, makemigrations, migrate etc. Then as the admin when I add a record to PROJECT with a value 'PROJECT1', is it possible for Django to create a copy of the BASEMODEL called BASEMODEL_PROJECT1 ? I'm not looking for the exact code, just looking for any ideas or links as to how I could possibly do so. Thanks. -

How to split django 'models.py', 'views.py', 'serializers.py' files into multiple files
Hello, For educational purposes, I am building a django app with multiple models and relationships. According to the official tutorial and many implementations I found online, the database models and serializers as well as views are all defined in single files: "models.py", "serializers.py", and "views.py". So, the project directory looks as follows: > my_app > migrations > __init__.py > admin.py > models.py > apps.py > serializers.py > tests.py > urls.py > views.py Depending on how many models are included in the app, those files may grow to hundreds or even thousands lines of code. As a result, developing and maintaining the application becomes extremely challenging. I would like to split these files so that every model (and coresponding serializer and view) will be defined in a separate per-model files. as follows: > my_app > migrations > models > __init__.py > model1.py > model2.py > model3.py > model4.py > serializers > __init__.py > model1_serializers.py > model2_serializers.py > model3_serializers.py > model4_serializers.py > views > __init__.py > model1_views.py > model2_views.py > model3_views.py > model4_views.py > __init__.py > admin.py > apps.py > tests.py > urls.py I encountered some difficulties in splitting these files and have not yet found an optimal solution.

I have also rendered a html template to display the form and allow the user to place the order by indicating the number of pages. My views.py is as follows: def OrderView(request): order_list = Order.objects.all() if request.POST: form = OrderingForm(request.POST) if form.is_valid(): form.save() return redirect('home') return render(request, 'orderingsystem/ordercreate.html', {"form": OrderingForm}) My aim is to display a the total price on the side of the order page as soon as the customer selects number of pages without any HttpResponse because the form is not yet submitted at this stage. For example: If the Customer selects one page, the total price to be displayed = 1 * 20 = 20; if the customer selects 2 pages, the sidebar widget that displays total price updates automatically to 2 * 20 = 40, without any Http call. In other words, I want something like JavasScript to call def total_price() in my …
