Question

我是flask / python的新手，正在尝试调试其他人的教程。这是他们所有文件的结构：

/flask_project
    /app.py
    /myprojects
        /__pycache__
        /__init__.py
        /forms.py
        /models.py
        /base.html
        /login.html
        /models.html
        /register.html
        /home.html

但是，当尝试访问第一个必需的html文件-home.html时，它给我一个“找不到烧瓶模板”错误。我尝试将myprojects文件夹重命名为模板，但这没有帮助。 Flask文档也使我感到困惑-我有一个带有代码的 init .py文件，但是我认为app.py本身是一个模块。这是app.py的代码：

# app.py
from myprojects import app, models, db
from flask import render_template, redirect, request, url_for, flash, abort
from flask_login import login_user, login_required, logout_user
from forms import LoginForm, RegistrationForm 

@app.route('/')
def home():
    return render_template('home.html')

@app.route('/welcome')
@login_required
def welcome_user():
    return render_template('welcome_user.html')

@app.route('/logout')
@login_required
def logout():
    logout_user()
    flash("You logged out!")
    return redirect(url_for('home'))

@app.route('/login', methods = ['GET', 'POST'])
def login():
    form = LoginForm()
    if form.validate_on_submit():
        user = User.query.filter_by(email = form.email.data).first()
        
        if user.check_password(form.password.data) and user is not none:
            login_user(user)
            flash('Logged in successfully!')
            
            next = request.args.get('next')
            
            if next == None or notnext[0] == '/':
                next = url_for('welcome_user')
                
            return redirect(next)
        
    return render_template('login.html', form=form)

@app.route('/register', methods=['GET', 'POST'])
def register():
    form = RegistrationForm(request.form)
    if request.method == "POST" and form.validate():
        user = User(email = form.email.data, 
            username = form.username.data, password = form.password.data)
        db.session.add(user)
        db.session.commit()
        flash("Thanks for registering!")
        return redirect(url_for('login'))
    return render_template('register.html', form=form)

if __name__ == '__main__':
    app.run(debug = True)

找不到烧瓶模板
