#url_for(params = {}) ⇒ Object

Examples of how to use url_for method:

url_for ‘/some_url’

> /some_url

When generating a new URL, missing values may be filled in from the current request’s parameters. For example, if application name or model are not specifyed in the call parameters, they would be filled from the request.

url_for :action => :index

> /application/model

url_for :action => :create

> /application/model

url_for :action => :new

> /application/model/new

url_for :action => :show, :id => ‘12’

> /application/model/12/show

url_for :model => :another_model, :action => :show, :id => ‘12’

> /application/another_model/12/show

url_for :controller => :another_controller, :action => :show, :id => ‘12’

> /application/another_controller/12/show

url_for :application => :another_app, :model => :another_model, :action => :show, :id => ‘12’

> /another_app/another_model/12/show

url_for :action => :create, :query => => ‘John Smith’, ‘address’ => “john.smith.com”

> /application/model?name=John%20Smith&address=http%3A%2F%2Fjohn.smith.com

url_for :action => :show, :id => ‘12’, :fragment => “an-anchor”

> /application/model/12/show#an-anchor
