I explain my problem as better as I can:

I have a program written in 3 modules. I want to save some data from a site (Now I'm using a local host to make tests) to some variables and show some variables' value in the index page in this way:

1.- [Script: Text_Variable] <-- [localhost: ask_for_text]
2.- [Script: Menu_Options] --> [localhost: show_menu]
3.- [Script: Option_Variable] <-- [localhost: user_option]
4.- [Script: Response_Variable] --> [localhost: show_response]

Depending the value of "Text_Variable", the program do: 1 --> 4 or 1 --> 2 --> 3 --> 4
I could import from the script in "views.py" without problems functions and variables which made the process 1 --> 4 work properly but I have a problem with the function "Menu_Options" :
I use "POST" method for getting the data from the page, so I need to pass the argument "request" to my function in "views.py" but I call this function from the script, so I need to import that "request" in the module. I tried with these:

Python
import newproject.views
import django
from django.http import request


script_module.py:

Python
...
Pregunta = 'question?'
Opciones = [op1, op2...]

opc = boletin.views.Menu_Opciones(request, Pregunta, Opciones)
...


views.py:

Python
...
def Menu_Opciones(request, Pregunta, Opciones):
    request.session['ops'] = Opciones
    request.session['preg'] = Pregunta
    Menu_Opc(request)
    
    opcion = request.session['op']
    return opcion
...


Python
...
def Menu_Opc(request):
    Opciones = request.session['ops']
    Pregunta = request.session['preg']
    form = OpcionesForm(request.POST or None)
    form.Campo_Opciones.widget.choices = Opciones
    context = {
        'pregunta': Pregunta,
        'form': form,
    }
    if form.is_valid():
        opcion = form.instance.ops.value() + 1
        request.session['op'] = opcion
    return render(request, "inicio.html", context)
...


but I had this error: "Menu_Opciones() missing 1 required positional argument: 'Opciones'"

Here is the traceback:

Am I doing something wrong this way or there are a better way to do this?
Please, consider I'm new in this language.
Thanks in advance.

What I have tried:

I tried to import the request object in the script in this way:

import django
from django.http import request

but it seems to be "ignored"

1 solution

I fixed it! I realised that I forgot to pass the "request" parameter when I call my script main funcion. That's why my external script "didn't know" what "request" was.
