i am getting a variable using request.args. I would like to add another app route to obtain a new variable that will link to the client_id in the app route '/search/'. how do i keep this client_id variable when adding another app route?

from flask import Flask

from flask import render_template, url_for, request, redirect

from flask import make_response

app = Flask(__name__)

import pandas as pd





@app.route('/', methods=['GET'])

def index():

    res = '''<form action="/search" method=>

                    <p><input type="text" name="query" value="test"></p>

                    <p><input type="submit" value="Search"></p>

                    <br />

    </form>'''

    return res 



@app.route('/search', methods=["GET","POST"])

def suggestion():

    client_id = request.args['query']  

    return render_template('untitled2.html')





if __name__ == '__main__':

    app.run(debug=True) 

for example, I want to add this app route

@app.route('/csv/')

def download_csv():

    #can't figure out how to obtain the client_id var

    client_id = ??? 

    model_id=request.args['textid']

    model_id1=request.args['textid1']

    model_id2=request.args['textid2']



    # return response

    df=recommender.update_history(client_id, model_id, model_id1, model_id2)

    df= recommender.get_csv()

    resp = make_response(df.to_csv(encoding='iso-8859-1',index=False))

    resp.headers["Content-Disposition"] = "attachment; filename=export.csv"

    resp.headers["Content-Type"] = "text/csv"

    return resp

here's what I have on my html template where i need to grab the variable that was formerly in request.args['text'] and send it to the new app route "/csv" along with the new form data:

untitled2.html:

 <div class="form-group">

            <h4>Suggestions for {{ request.args['text']  }}  </h4>

            <form action ="/csv">

             <form method="POST">

                <br>

                <label>Enter 3 suggestions</label>

                <br>

                <input name="textid", placeholder="Suggested Model ID #", value="{{ request.form['textid'] }}"/>

                <input name="textid1", placeholder="Suggested Model ID #", value="{{ request.form['textid1'] }}"/>

                <input name="textid2", placeholder="Suggested Model ID #", value="{{ request.form['textid2'] }}"/>



                <input type="submit" >

              </form>

          </div>



 <h4>Entered Suggestions:{{ request.form['textid'] }}  {{ request.form['textid1'] }}  {{ request.form['textid2'] }} </h4>

You can keep your client_id variable, by adding it to session, save it in cookie or
use gobject.

For session, just use instead of client_id, session['client_id'] = request.args['query']. You can always get it with session['client_id'] . Additionally, you must set secret key in config of app like so app.config['SECRET_KEY'] = 'My secret key'.
