So I have a login form and a signup form on home.html. I have custom validators set up on my signup form that when a user tries to sign up with a username or email that already exists, it will show error on the form. But when I do this, it doesn't show me any error. It works on a different route where I have only one form.
Below is the forms.py file:
class RegistrationForm(FlaskForm):
username_regis = StringField('Username',
validators=[DataRequired(), Length(min=5, max=20)])
email_regis = EmailField('Email',
validators=[DataRequired(), Email()])
password_regis = PasswordField('Password', validators=[DataRequired()])
submit_regis = SubmitField('Sign Up')
def validate_username_regis(self, username_regis):
user = User.query.filter_by(username=username_regis.data).first()
if user:
raise ValidationError('That username is taken. Please choose a different one.')
def validate_email_regis(self, email_regis):
user = User.query.filter_by(email=email_regis.data).first()
if user:
raise ValidationError('That email is taken. Please choose a different one.')
Below are the routes.py functions for main and signup:
@app.route("/", methods=['GET', 'POST'])
def home():
login_form = LoginForm(request.form, prefix="login-form")
regis_form = RegistrationForm(request.form, prefix="register-form")
events_main = Event.query.order_by(Event.date_posted.desc())
return render_template('home.html', login_form=login_form, regis_form=regis_form)
@app.route("/register", methods=['POST'])
def register():
regis_form = RegistrationForm(request.form, prefix='register-form')
if regis_form.validate_on_submit():
hashed_password = bcrypt.generate_password_hash(regis_form.password_regis.data).decode('utf-8')
user = User(username=regis_form.username_regis.data, email=regis_form.email_regis.data, password=hashed_password)
db.session.add(user)
db.session.commit()
flash('Your account has been created! You are now able to log in', 'success')
return redirect(url_for('home'))
return redirect(url_for('home'))
Below is the home.html file:

<form method="POST" action="{{ url_for('login') }}">
