I'm struggeling with this bug for several days now and don't know how to fix it. I didn't find an answer in all the previous questions.
Except my personal touch I finished pset7. If I start flask everything works just fine but if I do check50 I get this error message:
I don't really understand how there can be an 400 error when it's working with flask. If I check in the chrome developer tools or the terminal I can also see no errors. I know that if you call "return apology("text") it will return an 400 Error but I don't call it here. Do I need to change some lines in helpers.py? And also I don't understand why the expected status code of "registration rejects duplicate username" is 200, shouldn't it be 400 because an error will occur? I am not sure if my bug is in the register part of application.py but I will post it here anyway. I would be really thankful if you can have a look at my code and maybe give me a hint where I can look for my bug. Thank you very much in advance.
@app.route("/register", methods=["GET", "POST"])
def register():
"""Register user"""
# User reached route via POST (as by submitting a form via POST)
if request.method == "POST":
# Ensure username was submitted
if not request.form.get("username"):
return apology("Missing username")
# Ensure password was submitted
elif not request.form.get("password"):
return apology("Missing password")
# Ensure password was confirmed
elif not request.form.get("confirmation"):
return apology("Missing password confirmation")
# Ensure password and confirmation match
elif request.form.get("username") != request.form.get("confirmation"):
return apology("The passwords do not match! Please Try again")
hash = generate_password_hash(request.form.get("password"), method='pbkdf2:sha256', salt_length=8)
result = db.execute("INSERT INTO users (username, hash) VALUES (:username, :hash)", username = request.form.get("username"), hash = hash)
if not result:
return apology("The username is already taken")
rows = db.execute("SELECT * FROM users WHERE username = :username",
username = request.form.get("username"))
# Remember which user has registered
session["user_id"] = rows[0]["id"]
# Redirect user to home page
return redirect(url_for("index"))
# User reached route via GET (as by clicking a link or via redirect)
else:
return render_template("register.html")
