python - How do you load information into a database using flask? -

-

trying teach myself flask making web app. i'm having trouble posting inputs user database , when load page , try submit info through form 405 error:

"get / http/1.1" 200 -,

"post / http/1.1" 405 -

any insight appreciated, thanks.

here python snippet:

session = dbsession()  app = flask(__name__)  @app.route('/') def index(methods=['get','post']):     print request.method     if request.method == 'post':         instances = session.query(vocab)         newitem = vocab(id=len(instances), word=request.form['new_word'])         session.add(newitem)         session.commit()     instances = session.query(vocab)     return render_template('vocab_template.html', instances = instances)

the html template: 

<!doctype html>  <html>  	<head>	  		<title>vocab</title>  	</head>    	<body>  		<div>  			<h1>words!</h1>  			<ul id='words'>  				{% in instances %}  					<li>  					{{i.word}}					  					</li>  				{% endfor %}  			</ul>  			<form action="/" method="post">  				<input type="text" name='new_word'>  				<input type="submit" value="add" name='submit'>  			</form>  		</div>  	</body>    </html>

you close

@app.route('/',methods=['get','post']) def index():     print request.method ...
