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 ?
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
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')
Try to use that
get_class_swimming_students_path(:start_date => "2013-01-01", :end_date => "2013-02-02")
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
