Hi, I am trying to integrate my existing code into django. How do i access models.py from my external code.I tried putting it in the same apps directory it did not work. Is there a way ?

My Case: I have a web parsing code that takes data from the web and prints it. I want to integrate it with django so as to save that data in the db and print it out in the web page. I want the input to come from the webpage and when i hit submit it triggers the parsing code and gives output on the page.

I have the django server up and running, created the apps (startapp), have the table created via models.py, have the urls.py setup. My question is how or where do I put my external code to make it trigger to access models .py, will it execute by itself when I start the server and hit the submit button ( i know i have to configure this one)
