Question

I’m a bit rusty with Rails. I’m trying to create a route that should accept an arbitrary number of parameters from a link_to, but I keep getting routing errors.

My link currently looks like this:

<%= link_to "Send Params", :action => "recieve", :controller => "pages", :name => "Test", :email => "test2" %>

And my route looks like this:

match 'pages/receive/*params' => 'pages#receive'

And I get:

No route matches {:action=>"recieve", :controller=>"pages", :name=>"Test", :email=>"test2"}

If I do:

<%= link_to "Send Params", :name => "Test", :email => "test2" %>

And:

match '/*params' => 'pages#receive'

It kinda works, but my method in the controller isn’t getting called.

So, how should the route and link_to look?

Correct me if I’m wrong, but I think there is no need in this *params in you routes. You can do like that:

# routes.rb
get 'pages/receive', :to => 'pages#receive'

# in view
<%= link_to "Send Params", :action => "receive", :controller => "pages", 
                           :name => "Test", :email => "test2" %>

# it generates link with path like /pages/receive?name=Test&email=test2

# in PagesController#receive
name = params[:name]   # => "Test"
email = params[:email] # => "test2"

In Rails params is a helper method (that you can use in controllers and views) that returns a hash containing all GET and POST parameters.
