I'm using flask to make a login system and when I POST the form from the HTML form and I keep getting the following error: werkzeug.exceptions.HTTPException.wrap.<locals>.newcls: 400 Bad Request: KeyError: 'username'.
I've looked up the error on Google and have gotten nowhere.
My HTML code is this:
<div class="card rounded-0" id="register_form">
<div class="card-header">
<h3 class="mb-0">Register</h3>
</div>
<div class="card-body">
<form class="form" role="form" method="POST" action="/auth/register" id="form">
<div class="form-group">
<label for="email">Email</label>
<input type="text" class="form-control form-control-lg rounded-0" id="email" required="">
<div class="invalid-feedback">Enter your Email.</div>
</div>
<div class="form-group">
<label for="username">Username</label>
<input type="text" class="form-control form-control-lg rounded-0" id="username" required="">
<div class="invalid-feedback">Enter your Username.</div>
</div>
<div class="form-group">
<label>Password</label>
<input type="password" class="form-control form-control-lg rounded-0" id="password" required="">
<div class="invalid-feedback">Enter your Password.</div>
</div>
<button type="submit" class="btn btn-success btn-lg float-right" id="btnLogin_regi">Register</button>
</form>
<p>Already have an account? </p><a class="btn btn-primary btn-lg" tabindex="-1" role="button" id="login_btn">Login</a>
</div>
</div>
My Python code is this:
@app.route('/auth/register', methods=["POST"])
def auth_post():
if request.method == "POST":
try:
q = database.query(User).filter(User.username == request.form.get("username"))
exists = database.query(q.exists()).scalar()
if exists:
return render_template("auth.html", error="User with same username/email exists.")
else:
username = str(request.form["username"])
password = str(request.form["password"])
email = str(request.form["email"])
print("Username: "+username+", Password: "+password+", Email: "+email)
temp = User(username=username, password=password, email=email)
database.add(temp)
database.commit()
except sqlalchemy.orm.exc.MultipleResultsFound:
return "Well this shouldn't be happening but it is. Join our Discord Server and tell one of the devs that the following error occured:\n<code>sqlalchemy.orm.exc.MultipleResultsFound (register)</code>"
I expect it to push the data to the SQLite Database, and once it does that, I will add more features after that.
