Build a CRUD App with SQLAlchemy - Create a ToDo App

Steps:

1. 创建一个文件夹
2. 在文件夹下，create a python file, named “app.py”

from flask import Flask, render_template

app = Flask(__name__)

@app.route('/')
def index():
    return render_template('index.html', data=[{
        'description': 'Todo 1'
    }, {
        'description': 'Todo 2'
    }, {
        'description': 'Todo 3'
    }])

3. In the project folder, create a new folder named “templates”. Under the templates folder, create an index.html file.

    
        
    
    
        

            {% for d in data %}
                

                    {{ d.description }}
                
            {% endfor %}
        
    

4. Run the app.py file with this command:

$ FLASK_APP=app.py FLASK_DEBUG=true flask run
