Web app design questions - RoR 3

This is my first web app that i am developing and i have some design questions, i have a few book about RoR3 but i dont seem to find answers to my questions. My application is based on Ruby on rails 3

I am not looking for detailed answers here, if you can just point me to a topic name that i could learn about that can answer my qustions, such as "names resources" , "hidden fields" .....

My questions: 1- How to send information between View A and controller B. Example, i am on the View for "Company" when i click create employee i am calling the "new view" for the employee so i am now on a different view, how can i pass to the new employee action the ID of the company? Since i am now on a different view ? i don’t want to use nested resources What are the different ways to send information across different controllers/views

2- ruby URLs: i can view am item in my model via the URL: http://localhost:3000/Companies/1 I don’t want the url to contain the index of the item, each company has a name and i want to display this name in the url such as http://localhost:3000/Companies/myCompany How can i change the url structure of rails?

  1. Pass the company id as parameters at create employee link .

In the controller ,receive the params like def new company_id = params[:company_id] .... end

  1. For using some string instead of id , use gem 'friendly_id' Make sure your reference string should be unique.

For your first question, you can pass the parameters with the link (assuming you have employee and company variables accessible to your view):

Edit: this should work:

= link_to "create employee", :controller => "employees", :action => "new", :company_id => @company.id

And in the Employees controller:

def new
  company_id = params[:company_id]
  # check that company_id is not nil before doing stuff with it
end

I'm not sure why doing this ignores any extra parameters:

= link_to "create employee", new_employee_path, :company_id => @company.id

For your second question, this is what you're looking for.
