500 error with MySQLdb Python when pulling data from tables

Question

I am unsure why this code is giving me a 500 error on my web app with Flask, can someone tell me where my logic is wrong? I have a feeling it has to do with the sha256_crypt.verify() functions, but unsure how to get around this. Just trying to pull all the data on a user from my tables and put it into the session variable. Let me know, thanks!

@app.route('/login/', methods=['GET','POST'])
def login_page():
    error = ''
    try:
        c, conn = connection()
        if request.method == "POST":
            c.execute("SELECT * FROM clients WHERE email = (%s)", (thwart(request.form['email']),))
            pdata = c.fetchone()[3]

            if sha256_crypt.verify(request.form['password'], pdata):
                #get info from clients table
                c.execute("SELECT * FROM clients WHERE email = (%s)", (email,))
                clients_results = fetchall()
                clientcid = clients_results[0]
                #get info from cpersonals table
                c.execute("SELECT * FROM cpersonals WHERE cid = (%s)", (clientcid,))
                cpersonals_results = fetchall()

                conn.commit()
                c.close()
                conn.close()


                session['logged_in'] = 'client'
                session['clientcid'] = clientcid
                session['email'] = email
                session['phone'] = clients_results[1]
                session['rating'] = clients_results[4]
                session['first_name'] = cpersonals_results[1]
                session['last_name'] = cpersonals_results[2]
                session['address'] = cpersonals_results[3]
                session['czip'] = cpersonals_results[4]
                session['reg_date'] = cpersonals_results[5]
                flash("You are now logged in.")
                return redirect(url_for("ask"))

            else:
                error = "Invalid credentials, try again."

        return render_template("login.html", error = error)

    except Exception as e:
        #flash(e)
        error = "Invalid credentials, try again."
        return render_template("login.html", error = error)

Log: (sorry not sure how to post this properly)

Answer 1

I fixed this awhile back and wanted to update the post in case anyone else runs into this.

So all I did was take the c.execute() functions out of the sha256_crpt IF statement, and put them at the beginning of the function for the page that login redirects to. Every user visits the first page so the user session will always have these values.

As such :

@app.route('/ask/', methods=['GET','POST'])
def ask():
    #clients come here first
    error = ''
    try:
        c, conn = connection()
        #grab all the clients info
        email = session['email']
        c.execute("SELECT cid FROM clients WHERE email = (%s)", (thwart(email),))
        clientcid = c.fetchone()[0]
        c.execute("SELECT phone FROM clients WHERE email = (%s)", (thwart(email),))
        phone = c.fetchone()[0]
        c.execute("SELECT rating FROM clients WHERE email = (%s)", (thwart(email),))
        rating = c.fetchone()[0]
        c.execute("SELECT first_name FROM cpersonals WHERE cid = (%s)", (clientcid,))
        first_name = c.fetchone()[0]
        c.execute("SELECT last_name FROM cpersonals WHERE cid = (%s)", (clientcid,))
        last_name = c.fetchone()[0]
        c.execute("SELECT address FROM cpersonals WHERE cid = (%s)", (clientcid,))
        address = c.fetchone()[0]
        c.execute("SELECT city FROM cpersonals WHERE cid = (%s)", (clientcid,))
        city = c.fetchone()[0]
        c.execute("SELECT state FROM cpersonals WHERE cid = (%s)", (clientcid,))
        state = c.fetchone()[0]
        c.execute("SELECT zip FROM cpersonals WHERE cid = (%s)", (clientcid,))
        czip = c.fetchone()[0]
        c.execute("SELECT reg_date FROM cpersonals WHERE cid = (%s)", (clientcid,))
        reg_date = c.fetchone()[0]
        conn.commit()
        c.close()
        conn.close()


        session['logged_in'] = 'client'
        session['clientcid'] = clientcid
        session['phone'] = phone
        session['rating'] = rating
        session['first_name'] = first_name
        session['last_name'] = last_name
        session['address'] = address
        session['city'] = city
        session['state'] = state
        session['czip'] = czip
        session['reg_date'] = reg_date
