Question

In Rails 2 generators, it’s possible to pass data to the template in the following manner:

record.template(
  "src.html.erb",
  "dest.html.erb",
  :assigns => { :id => id, :name => name }

In Rails 3, it looks like template is the new method. Unfortunately, it looks like the third parameter, config, only accepts a :verbose option. Attempting to pass values via :assigns doesn’t seem to work.

Does anyone know how I can pass dynamic value to my Rails 3 template?

Example of passing parameters to views in Rails 3.

https://github.com/rails/rails/blob/master/railties/lib/rails/generators/erb/controller/controller_generator.rb

# ...
actions.each do |action|
  @action = action
  @path = File.join(base_path, filename_with_extensions(action))
  template filename_with_extensions(:view), @path
end

Template:

https://github.com/rails/rails/blob/master/railties/lib/rails/generators/erb/controller/templates/view.html.erb

<h1><%= class_name %>#<%= @action %></h1>
<p>Find me in <%= @path %></p>
