英文:
I'm trying to make a registeration page using WTForms but I'm having difficulties getting the submit button to work. When I fill all the page's fields and click the 'Submit' button nothing happens whatsoever, I checked the database to see if the form instance was even created and it wasn't, I also don't get redirected to the desired URL after submitting.
I'm currently following a Flask tutorial for Python on YT by JimShapedCoding Link to video
Here's my code:
init.py
from flask import Flask, render_template
from flask_sqlalchemy import SQLAlchemy #tables using classes
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///market.db'
app.config['SECRET_KEY'] = 'b61198e1258118d75478e8e4'
db = SQLAlchemy(app)
from market import routes
forms.py
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
class RegisterForm(FlaskForm):
username = StringField(label='Enter your username:')
email_address = StringField(label='Email:')
pw1 = PasswordField(label='Password:')
pw2 = PasswordField(label='Confirm Password:')
submit = SubmitField(label='Create Account')
models.py
from market import db
class User(db.Model):
id = db.Column(db.Integer(), primary_key=True)
username = db.Column(db.String(length=18), nullable=False, unique=True)
email_address = db.Column(db.String(length=40), nullable=False, unique=True)
password_hash = db.Column(db.String(length=60), nullable=False)
budget = db.Column(db.Integer(), nullable=False, default=1000)
items = db.relationship('Item', backref='owned_user', lazy=True)
def __repr__(self):
return f"Item: {self.name}"
routes.py
from market import app
from flask import Flask, render_template, redirect, url_for
from market.models import Item, User
from market.forms import RegisterForm
from market import db
@app.route('/register', methods=['GET', 'POST'])

form = RegisterForm()
if form.validate_on_submit():
user_to_create = User(username=form.username.data,
email_address=form.email_address.data,
password_hash=form.pw1.data)
db.session.add(user_to_create)
db.session.commit()
return redirect(url_for('market_page'))
return render_template('register.html', form=form)

How the registeration page looks like
After revising my code multiple times & making sure it's like what was in the video, I still couldn't manage to fix my issue or even impact it.
What I tried:
I tried using app.app_context().push()
before the db.session.add(user_to_create)
line in routes.py
I made sure all the variable names matched
I tried running it using $env:FLASK_APP = 'init.py' followed by flask run
This is how my terminal looks like whenever the page is refreshed:
127.0.0.1 - - [10/Apr/2023 23:09:02] "GET /register HTTP/1.1" 200 -
127.0.0.1 - - [10/Apr/2023 23:09:11] "GET /favicon.ico HTTP/1.1" 404 -
If anyone may offer some help that'll be wonderful as I have been trying to debug this issue for around 3 days now.

Your code contains a typo in the register.html file. The div element that encloses the form is missing the trailing > before the form element begins.
<div class="container">
<!-- Your form here. -->
</div>
