TurboGears - URL Hierarchy
TurboGears - URL Hierarchy
Sometimes, a web apppcation may require a URL structure that is having more than one level. TurboGears can traverse object hierarchy to find appropriate method that can handle your request.
A project ‘quickstarted’ with gearbox has a BaseController class in project’s pb folder. It is available as ‘Hello/hello/pb/base.py’. It serves as base class for all sub controllers. In order to add a sub level of URL in apppcation, design a sub class called BlogController derived from BaseController.
This BlogController has two controller functions, index() and post(). Both are designed to expose a template each, blog.html and post.html.
Note − These templates are put inside a sub folder − templates/blog
class BlogController(BaseController):
@expose( hello.templates.blog.blog )
def index(self):
return {}
@expose( hello.templates.blog.post )
def post(self):
from datetime import date
now = date.today().strftime("%d-%m-%y")
return { date :now}
Now declare an object of this class in RootController class (in root.py) as follows −
class RootController(BaseController): blog = BlogController()
Other controller functions for top level URLs will be there in this class as earper.
When a URL http://localhost:8080/blog/ is entered, it will be mapped to index() controller function inside BlogController class. Similarly, http://localhost:8080/blog/post will invoke post() function.
The code for blog.html and post.html is as below −
Blog.html
<html>
<body>
<h2>My Blog</h2>
</body>
</html>
post.html
<html>
<body>
<h2>My new post dated $date</h2>
</body>
</html>
When a URL http://localhost:8080/blog/ is entered, it will produce the following output −
When a URL http://localhost:8080/blog/post is entered, it will produce the following output −
