tornado-wtforms 0.0.1

WTForms extensions for Tornado fork.

Candango Tornado WTForms

WTForms extensions for Tornado forked from WTForms-Tornado.

We will derive the amazing work developed by the original project and add further improvements.

The project WTForms-Tornado will continue to be matained. Check the original project to see if it fit the needs your project/application needs.

Usage

import tornado.ioloop
import tornado.web

from wtforms.fields import IntegerField
from wtforms.validators import DataRequired
from tornado_wtforms.form import TornadoForm


class SumForm(TornadoForm):

   a = IntegerField(validators=[DataRequired()])
   b = IntegerField(validators=[DataRequired()])


class SumHandler(tornado.web.RequestHandler):
   def get(self):
       self.write("Hello, world")

   def post(self):
       form = SumForm(self.request.arguments)
       if form.validate():
           self.write(str(form.data['a'] + form.data['b']))
       else:
           self.set_status(400)
           self.write("" % form.errors)


application = tornado.web.Application([
    (r"/", SumHandler),
])

if __name__ == "__main__":
   application.listen(8888)
   tornado.ioloop.IOLoop.instance().start()

Backwards Compatibility

We'll keep a backwards compatibility with the WTForms-Tornado but a depreciation warning will be logged.

This still works after the instalation:

from wtforms_tornado import Form

class LegacyForm(Form):

   pass

The tornado_wtforms.from.Form class is extending wtforms.form.TornadoForm and is available to be imported at wtforms_tornado module.

Just changing wtforms_tornado by tornado_wtforms and keep importing Form won't work, from tornado_wtforms import Form, because Form is not referenced in tornado_wtforms module. Either you do from tornado_wtforms.form import TornadoForm or from tornado_wtforms.form import Form. The second option will still trigger a depreciation after instantiating a Form instance.
