galaxy.web package

The Galaxy web application framework

galaxy.web.url_for(*args, **kargs)

Generates a URL

All keys given to url_for are sent to the Routes Mapper instance for generation except for:

anchor          specified the anchor name to be appened to the path
host            overrides the default (current) host if provided
protocol        overrides the default (current) protocol if provided
qualified       creates the URL with the host/port information as
                needed

The URL is generated based on the rest of the keys. When generating a new URL, values will be used from the current request’s parameters (if present). The following rules are used to determine when and how to keep the current requests parameters:

• If the controller is present and begins with ‘/’, no defaults are used
• If the controller is changed, action is set to ‘index’ unless otherwise specified

For example, if the current request yielded a dict of {‘controller’: ‘blog’, ‘action’: ‘view’, ‘id’: 2}, with the standard ‘:controller/:action/:id’ route, you’d get the following results:

url_for(id=4)                    =>  '/blog/view/4',
url_for(controller='/admin')     =>  '/admin',
url_for(controller='admin')      =>  '/admin/view/2'
url_for(action='edit')           =>  '/blog/edit/2',
url_for(action='list', id=None)  =>  '/blog/list'

Static and Named Routes

If there is a string present as the first argument, a lookup is done against the named routes table to see if there’s any matching routes. The keyword defaults used with static routes will be sent in as GET query arg’s if a route matches.

If no route by that name is found, the string is assumed to be a raw URL. Should the raw URL begin with / then appropriate SCRIPT_NAME data will be added if present, otherwise the string will be used as the url with keyword args becoming GET query args.
