Passing parameters from view to controller

Question

I got a bit of a newbie question. I\'m trying to pass a variable from my view to my controller. Is there anyway my method in my controller can receive variables from my view

You can add information to the params hash right through the link_to. I'm not sure exactly what you are trying to do but I did something like this recently to add the type of email I wanted when I link to the new email

<%= link_to 'Send Thanks', new_invoice_email_path(@invoice, :type => "thanks") %>

Now my params looks like:

{"type"=>"thanks", "action"=>"new", "controller"=>"emails", "invoice_id"=>"17"}

I can access the type via the params

email_type = params[:type]

Instead of a string, if you pass in the instance variable @rela you will get the object_id in the params hash.

Per the comment below, I'm adding my routes to show why the path new_invoice_email_path works:

resources :invoices do
  resources :emails
end
