Rails: URL/path with parameters

I would like to produce a URL as

/swimming/students/get_times/2013-01-01/2013-02-02

from this route

get_class_swimming_students GET /swimming/students/get_times/:start_date/:end_date(.:format) swimming/students#get_times

How do I pass parameters to get_class_swimming_students_path ?

You can also combine named parameters and not named parameters like this:

get_class_swimming_students_path('2013-01-01', '2013-02-02', gender: 'M')

in rails 4, type less with:

get_class_swimming_students_path(params1: value1, params2: "value2")

where value1 is a method and value2 is a string

get_class_swimming_students_path('2013-01-01', '2013-02-02')

In Rails, URL parameters are mapped to the router in the precise order in which they are passed. Consider the following:

# rake routes
my_route GET    /my_route/:first_param/:second_param/:third_param(.:format)

# my_view.html.erb
<%= link_to('My Route', my_route_path('first_param', 'second_param', 'third_param') %>
#=> <a href="/my_route/first_param/second_param/third_param">My Route</a>

Consider also the following case where foo and bar are static parameters positioned between dynamic parameters:

# rake routes
my_route GET    /my_route/:first_param/foo/:second_param/bar/:third_param(.:format)

# my_view.html.erb
<%= link_to('My Route', my_route_path('first_param', 'second_param', 'third_param') %>
#=> <a href="/my_route/first_param/foo/second_param/bar/third_param">My Route</a>

In the final example, arguments will appear as URL parameters in the order in which they were passed, but not necessarily in the same sequence.

EDIT:

The following syntax is equivalent to the first snippet. The primary difference is that it accepts arguments as named parameters, rather than in the order they're passed:

get_class_swimming_students_path(:start_date => '2013-01-01', :end_date => '2013-02-02')

For any path you can pass params like

get_class_swimming_students_path(:params1 => value1, :params2 => value2)

And In controller you can simply access those passed params as usual

Try to use that

get_class_swimming_students_path(:start_date => "2013-01-01", :end_date => "2013-02-02")
