500 Fehler mit MySQLdb Python beim Ziehen von Daten aus Tabellen

Question

Ich bin mir nicht sicher, warum dieser Code mir einen 500 Fehler auf meiner Web-App mit Flask gibt, kann mir jemand sagen, wo meine Logik falsch ist? Ich habe das Gefühl, dass es mit den Funktionen von sha256_crypt.verify() zu tun hat, aber ich bin mir nicht sicher, wie ich das umgehen soll. Ich versuche nur, alle Daten eines Benutzers aus meinen Tabellen zu ziehen und sie in die Sitzungsvariable einzufügen. Lass es mich wissen, danke!

@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 nicht sicher, wie diese richtig schreiben)

Answer 1

ich diese eine Weile zurück, fixiert und wollte die Post falls jemand aktualisieren sonst in dieser läuft.

Also alles, was ich tat, war, nimmt die c.execute() Funktionen aus der sha256_crpt IF-Anweisung, und sie für die Seite am Anfang der Funktion setzen, dass login Umleitungen an. Jeder Benutzer besucht die erste Seite, sodass die Benutzersitzung immer diese Werte hat.

Als solche:

@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
