Django: How can i pass user input value from models.py to other file(ex entity_exctraction.py)
I am new to Django so please guide if i am going on wrong way.
Problem Defination:
To take user input AS string and perform various manipulations on the input and save the modified value in the database.I also want to show this modified input as a json response.
For temporary purpose i have created 4 fields namely ticker,open,close,volume.I want to transfer the open value from models.py to entity_exctraction.py file and multiply by 2 and save the updated value to the database.
I tried to write the same logic in the models.py (commented part) and its working fine.but what i want is to write all business logic in some different file.
Models.py
from django.db import models
from .entity_exctraction import Exctraction
class Stock(models.Model):
ticker = models.CharField(max_length=10)
open = models.FloatField()
close = models.FloatField()
volume= models.IntegerField()
open_val = Exctraction.update(open)
#def save(self, force_insert=False, force_update=False, using=None,
# update_fields=None):
# print(self.open)
# self.open = self.open * 2
# super(Stock, self).save()
def __str__(self):
return self.ticker
entity_exctraction.py
from django.db import models
class Exctraction():
def update(val):
val = val * 2.0
return val
serializers.py
from rest_framework import serializers
from .models import Stock
class StockSerializer(serializers.ModelSerializer):
class Meta:
model = Stock
print(type(model))
#model.open=model.open*2
#fields = ('ticker', 'volume')
fields = '__all__'

I can't see why you need an actual Extraction class. Why not just functions in extraction.py?

@DanielRoseman Actually i want to perform several task (related to natural language processing) on the one user input string. So i want whole bunch of code in separate python file.

@DanielRoseman i also tried writing direct function but now it is giving me error unsupported operant type. As i am passing "open" which is having FloatField type and multiplaying with 2.It is not passing original value to other file.
