Blog Posts的提交的提交

让我们从简单的开始。首页上必须有一张用户提交新的post的表单。

首先我们定义一个单域表单对象（fileapp/forms.py）：

class PostForm(Form):

post = TextField('post', validators = [Required()])

<h1>Hi, {{g.user.nickname}}!</h1>

<form action="" method="post" name="post">

{{form.hidden_tag()}}

<table>

<tr>

<td>Say something:</td>

<td>{{ form.post(size = 30, maxlength = 140) }}</td>

<td>

{% for error in form.errors.post %}

<span style="color: red;">[{{error}}]</span><br>

<td></td>

</tr>

</table>

</form>

{% for post in posts %}

<p>

{{post.author.nickname}} says: {{post.body}}

</p>

{% endfor %}

{% endblock %}

@app.route('/', methods = ['GET', 'POST'])

@app.route('/index', methods = ['GET', 'POST'])

@login_required

def index():

form = PostForm()

if form.validate_on_submit():

post = Post(body = form.post.data, timestamp = datetime.utcnow(), author = g.user)

db.session.add(post)

db.session.commit()

},

{

'author': { 'nickname': 'Susan' },

'body': 'The Avengers movie was so cool!'

}

]

return render_template('index.html',

title = 'Home',

form = form,

posts = posts)
