+## What is tornado-swagger?
+tornado is a wrapper for tornado which enables swagger-ui support.
+
+In essense, you just need to wrap the Api instance and add a few python decorators to
+get full swagger support.http://swagger.io/
+
+
+## How to use:
+
+
+```python
+from tornado.web import RequestHandler, HTTPError
+from tornado_swagger import swagger
+
+swagger.docs()
+
+# You may decorate your operation with @swagger.operation and use docs to inform information
+class ItemNoParamHandler(GenericApiHandler):
+ @swagger.operation(nickname='create')
+ def post(self):
+ """
+ @param body: create test results for a item.
+ @type body: L{Item}
+ @return 200: item is created.
+ @raise 400: invalid input
+ """
+
+# Operations not decorated with @swagger.operation do not get added to the swagger docs
+
+class ItemNoParamHandler(GenericApiHandler):
+ def options(self):
+ """
+ I'm not visible in the swagger docs
+ """
+ pass
+
+
+# Then you use swagger.Application instead of tornado.web.Application
+# and do other operations as usual
+
+def make_app():
+ return swagger.Application([
+ (r"/items", ItemNoParamHandler),
+ (r"/items/([^/]+)", ItemHandler),
+ (r"/items/([^/]+)/cases/([^/]+)", ItemOptionParamHandler),
+ ])
+
+# You define models like this:
+@swagger.model
+class Item:
+ """
+ @descriptin:
+ This is an example of a model class that has parameters in its constructor
+ and the fields in the swagger spec are derived from the parameters to __init__.
+ @notes:
+ In this case we would have property1, property2 as required parameters
+ and property3 as optional parameter.
+ @property property3: Item decription
+ @ptype property3: L{PropertySubclass}
