Project 4: TODO app but on the web! ☑️
To get familiar with pythons webframework i decided to extend the TODO app to the Web using Flask. It was a fairly easy task as I used a simple text file as my database - but the most difficult part probably was to find good resources that had a tutorials for beginners. After learning about various requests that occur in a server, it was easy to build the application. For now the apps can add items and delete all todo items.
@app.route('/') def index(): with open('todo.txt', 'r') as output:#reads the text file todo.txt which i am using a database new_list = output.read() x = new_list.splitlines()# x is each todo item return render_template('index.html', todo=x, id = index_id) @app.route('/add', methods=['POST']) def task(): task_content = request.form['content']#requests the content of the todo item with open('todo.txt', 'a') as output: global index_id index_id += 1 revised = (str(index_id)) string_length=len(revised)+1 output.write(revised.ljust(string_length))#numbering output.write(task_content) output.write("\n") return redirect(url_for('index')) #returns to the main page @app.route('/delete', methods=['POST'])#deletes all the item in the todo list def delete(): file = open("todo.txt","r+") file.truncate(0) file.close() global index_id index_id = 0 return redirect(url_for('index'))
