如何在python中为oracle连接传递变量值

Question

Im able to connect to Oracle Db successfully when i hardcode the Db details like " connection = cx_Oracle.connect("uname/pass@192.168.xxx.yyy:port/db")" but how to pass the variable values to connect to the db?

I tried some like this.

connection = cx_Oracle.connect("{}/{}@{}:{}/{}".format(uname,password,IP,port,db))

which is not working as expected so please share some thought on this to make it work.

def knowcobrand(request):
    value_type = request.POST.get('CobranSelection')
    cobrand_value = request.POST.get('cobrand')
    env = request.POST.get('NewEnvName')
    print(value_type)
    print(cobrand_value)
    print(env)
    # feed = Environments.objects.get(Q(Env_name__icontains=env))
    # print(feed.user_name)
    connection = cx_Oracle.connect("app/app@192.168.xxx.yy:port/db")

I want to use the variable's value of value_type and env for Db connection

Answer 1

EDIT: You should probably run through the Django tutorial , it will explain the basics of Django and using the ORM

You should configure your database connection in your settings

There is a specific example for oracle

You can now use the Django ORM ( after running migrations )

If you want a raw cursor for the database you can still use Django for this like so

from django.db import connection
with connection.cursor() as c:
    c.execute(...)
