Redirect_to with multiple controllers with shared tables - in rails

Question

Hey guys,

I'm pretty new to rails, so I apologize if this question has an obvious answer.

I have multiple controllers with records stored based on relations

for example, /books/1/titles/4

meaning the the title with ID 4, is only related to book with ID 1.

in an action such as destroy, how can I use redirect_to to go to /books/1/titles?

format.html { redirect_to :controller => 'books/:id/titles' , :action => 'show', :id => @book}

didn't work

Thanks in advance!

Answer 1

you'll want to use restful routes from here on out, and you are describing nested resources. topic is big. However, i suggest you see what happens when you

script/generate scaffold Book
script/generate scaffold Title

In there you will see how they destroy and redirect. You will learn a bunch just from that one command. then you can learn about associations between Title and Book (as in a title belongs to book and books has_many titles) and then finally adding your nested_route by doing:

map.resources :books, :has_many => :titles

oh and the stuff you got there won't work, btw.

Answer 2

Run

rake routes

to check your routes.

I think you'll want something like

book_titles_url(params[:book_id])
