Question

In rails how do you get information from view to use in a controller. Like if i have a page with a text field and a button, how would i send the value from the field (without a model) into my controller to work with it in one of my functions. Im using rails 3

Answer 1

Sounds like you could use a simple form, for example:

in your views/products/index.html.erb:

<% form_tag omg_products_path do %>
    <%= text_field_tag :my_input %>
    <%= submit_tag "Send input" %>
<% end %>

in your controllers/products_controller.rb:

def omg
    my_input = params['my_input']
    #do whatever you want with my_input
end

You will also want to configure routes.rb, for example like this:

resources :products do
    post :omg, :on => :collection
end
