=============================== Sanic-WTF - Sanic meets WTForms

Sanic-WTF makes using WTForms with Sanic_ and CSRF (Cross-Site Request Forgery) protection a little bit easier.

.. _WTForms: https://github.com/wtforms/wtforms .. _Sanic: https://github.com/channelcat/sanic

Quick Start

Installation

.. code-block:: sh

pip install --upgrade Sanic-WTF

How to use it

Intialization (of Sanic) ^^^^^^^^^^^^^^^^^^^^^^^^

.. code-block:: python

from sanic import Sanic

app = Sanic(name)

either WTF_CSRF_SECRET_KEY or SECRET_KEY should be set

app.config['WTF_CSRF_SECRET_KEY'] = 'top secret!'

@app.middleware('request') async def add_session_to_request(request): # setup session

Defining Forms ^^^^^^^^^^^^^^

.. code-block:: python

from sanic_wtf import SanicForm from wtforms import PasswordField, StringField, SubmitField from wtforms.validators import DataRequired

class LoginForm(SanicForm): name = StringField('Name', validators=[DataRequired()]) password = PasswordField('Password', validators=[DataRequired()]) submit = SubmitField('Sign In')

That's it, just subclass SanicForm and later on passing in the current request object when you instantiate the form class. Sanic-WTF will do the trick.

Form Validation ^^^^^^^^^^^^^^^

.. code-block:: python

from sanic import response

@app.route('/', methods=['GET', 'POST']) async def index(request): form = LoginForm(request) if request.method == 'POST' and form.validate(): name = form.name.data password = form.password.data # check user password, log in user, etc. return response.redirect('/profile') # here, render_template is a function that render template with context return response.html(await render_template('index.html', form=form))

.. note:: For WTForms users: please note that SanicForm requires the whole request object instead of some sort of MultiDict.
