Question

I want to pass id from view to controller. I know how to pass it by assigning a name to it like : :eid => @model["_id"]. And then I can fetch in controller using params[:"_id"].

But then the url would be /create?:eid="1234". But I want this: create/1234. So how can I do that

1. In view
2. How to fetch in controller.

Answer 1

You should spend some time learning about routes. You’ll need to define a route to do what you want to do.

In your config/routes.rb

match '/create/:eid' => 'underscored_name_of_controller_here#create', :as => :create

Then, in your view:

create_path(:eid => @model["_id"])

I’ll also suggest that the path of your route probably ought to be more descriptive that just /create/:_id but in the spirit of answering your question I’ve left it as such.
