Render page with rails

Question

I'm trying to make "friendship" between model Programme and Student. I do it with has_many :through model Relationship. In Relationship controller I have create action, which should redirect another page after the friendship occurs.

So, in Student show view I have link_to request friendship. I thought I will be able to enter Student show page, but instead it redirects me from Student index when I try to enter Student show view to another page. So I actually can't enter Student show, it just redirects me to other page.

Why is that happening? I want have redirect from Student show view after I click on "request friendship" to other model page.

Student show.html.erb

 <%= link_to "Request friendship with #{@student.name}",
 { :controller => "relationship", :action => "create",
 :id => @student.name },
 :confirm => "Send friend request to #{@student.name}?" %>

route.rb

 match "/students/:id" => "relationships#create"

UPDATED

Relationship controller

def create
  Relationship.request(@prog, @student)
  flash[:notice] = "Friend request sent."
  redirect_to prog_url
end

rake routes

    relationships_create GET    /relationships/create(.:format)   relationships#create
    relationships_destroy GET    /relationships/destroy(.:format)  relationships#destroy

post your controller and tell us where you want to be redirected — Zippie, Apr 07 '13 at 00:18
well actually yes. Where do you set up the `@prog` variable? you have to set it somehow — Zippie, Apr 07 '13 at 00:42
I added var @prog to create action in Relationship, right? After I get redirected to Prog index page, however I somehow skip Student show view and get redirected directly to Prog index. — , Apr 07 '13 at 00:48
I want to be redirected from Student show after I initiate request for friendship — , Apr 07 '13 at 00:49
yes yes, but you are not setting up the `@prog` and `@student` variables — Zippie, Apr 07 '13 at 00:51
I don't get. Can you give an example how I'm not setting up vars? — , Apr 07 '13 at 00:58
wouldn't you have to be on the programme page to add the request? how do you know which programme you are trying to be-friend? — Zippie, Apr 07 '13 at 01:01
little guidance always is appreciated! If I stuck I'll ask to navigate right way, but so far I'm fine. Cheers. — , Apr 08 '13 at 15:59

Not sure I understand completely what @prog should be, but this is the way to go

def create
  @student = Student.find_by_id(params[:id])
  @prog = Programme.find_by_id(params[:prog]) #You need to fill this in
  Relationship.request(@prog, @student)
  flash[:notice] = "Friend request sent."
  redirect_to @student # Or @prog, or whatever you'd like
end

You would probably need to pass the prog.id as well to the controller something like:

match "/students/:id/:prog" => "relationships#create"

and add

<%= link_to "Request friendship with #{@student.name}",
 { :controller => "relationship", :action => "create",
:id => @student.name, :prog => @student.current_programme },
# I don't know how you differ programmes, you'd have to work this one out  
:confirm => "Send friend request to #{@student.name}?" %>
