Iterating through multiline input, and match to database items - mysql

Question

I need help iterating through input to a webapp I'm writing, which looks like:
The users will be inputting several hundred (or thousands) of urls pasted from excel documents, each on a new line like this. Thus far, as you can see, I've created the input page, an output page, and written the code to query the database.
from flask import Flask,render_template, request
from flask_sqlalchemy import SQLAlchemy
from urllib.parse import urlparse
from sqlalchemy.ext.declarative import declarative_base
app = Flask(__name__)
app.config["DEBUG"] = True
app.config["SECRET_KEY"] = "secret_key_here"
db = SQLAlchemy(app)
SQLALCHEMY_DATABASE_URI = db.create_engine(connector_string_here))
app.config[SQLALCHEMY_DATABASE_URI] = SQLALCHEMY_DATABASE_URI
app.config["SQLALCHEMY_POOL_RECYCLE"] = 299
app.config["SQLALCHEMY_TRACK_MODIFICATIONS"] = False
db.Model = declarative_base()
class Scrapers(db.Model):
__tablename__ = "Scrapers"
id = db.Column(db.Integer, primary_key = True)
scraper_dom = db.Column(db.String(255))
scraper_id = db.Column(db.String(128))
db.Model.metadata.create_all(SQLALCHEMY_DATABASE_URI)
Session = db.sessionmaker()
Session.configure(bind=SQLALCHEMY_DATABASE_URI)
session = Session()
scrapers = session.query(Scrapers.scraper_dom, Scrapers.scraper_id).all()
#app.route("/", methods=["GET","POST"])
def index():
if request.method == "Get":
return render_template("url_page.html")
else:
return render_template("url_page.html")
#app.route("/submit", methods=["GET","POST"])
def submit():
sites = [request.form["urls"]]
for site in sites:
que = urlparse(site).netloc
return render_template("submit.html", que=que)
#scrapers.filter(Scrapers.scraper_dom.in_(
#next(x.scraper_id for x in scrapers if x.matches(self.fnetloc))
As is apparent, this is incomplete. I've omitted previous attempts at matching the input, as I realized I had issues iterating through the input. At first, I could only get it to print all of the input instead of iterating over it. And now, it prints like this:
Which is just repeating the urlparse(site).netloc for the first line of input, some random number of times. It is parsing correctly and returning the actual value I will need to use later (for each urlparse(site).netloc match scraper_dom and return associated scraper_id). Now, though, I've tried using input() but kept getting errors with [request.form["urls"]] not being an iterable.
Please help, it'd be much appreciated.
Output of sites:
New output with:
que = [urlparse(site).netloc for site in request.form["urls"].split('\n')]
