这里有一个关于如何在 Tornado 中使用 django ORM 和 django 表单的示例。您可以阅读在 Tornado Web 服务器中使用 Django 以获取一些信息。以下代码取自那里:
import sys
import os
import tornado.httpserver
import tornado.ioloop
import tornado.web
# django settings must be called before importing models
from django.conf import settings
settings.configure(DATABASE_ENGINE='sqlite3', DATABASE_NAME='dev.db')
from django import forms
from django.db import models
# Define your Model
class Message(models.Model):
"""
A Django model class.
In order to use it you will need to create the database manually.
sqlite> CREATE TABLE message (id integer primary key, subject varchar(30), content varchar(250));
sqlite> insert into message values(1, 'subject', 'cool stuff');
sqlite> SELECT * from message;
"""
subject = models.CharField(max_length=30)
content = models.TextField(max_length=250)
class Meta:
app_label = 'dj'
db_table = 'message'
def __unicode__(self):
return self.subject + "--" + self.content
# Define your Form
class DjForm(forms.Form):
subject = forms.CharField(max_length=100, required=True)
content = forms.CharField()
# Define the class that will respond to the URL
class ListMessagesHandler(tornado.web.RequestHandler):
def get(self):
messages = Message.objects.all()
self.render("templates/index.html", title="My title",
messages=messages)
class FormHandler(tornado.web.RequestHandler):
def get(self):
form = DjForm()
self.render("templates/form.html", title="My title", form=form)
def post(self):
data = {
'subject':self.request.arguments['subject'][0],
'content':self.request.arguments['content'][0],
}
form = DjForm(data=data)
if form.is_valid():
message = Message(**form.cleaned_data)
message.save()
self.redirect('/')
else:
self.render("templates/form.html", title="My title", form=form)
# map the Urls to the class
application = tornado.web.Application([
(r"/", ListMessagesHandler),
(r"/form/", FormHandler),
])
# Start the server
if __name__ == "__main__":
http_server = tornado.httpserver.HTTPServer(application)
http_server.listen(8888)
tornado.ioloop.IOLoop.instance().start()
这是django 和 tornado的另一个演示......
