I need some help with routes and params. I am developming some forums
for a web. I want to be able to create new replies once a post has been
created. So I create a post and then I have to put a link named "Reply".
What I want to do is Reply.create, and pass post_id as a param to this
Reply.create action. How can I make this link? How can I get this param
in replies controller?
I  think I can create a whole new action, but I would like to use
Reply.create.

Hi John,

I highly suggest you take a peek as the associations that Rails
provides.  A good place to start is the Rails Guides.
http://guides.rubyonrails.org/association_basics.html
and also the guide on routes (particularly the part on nested
resources)
http://guides.rubyonrails.org/routing_outside_in.html
These will make life much easier for you if you follow them.

Sorry for not really answering your question... :)


Again, I would go this route though.  :)

I think you have to have a look at Rails basics. A basic forum would
be something like:

forums has_many categories
categories has_many topics
topics has_many replies

then you have has_many routes like /forums/1/categories/1/topic and in
your routes.rb you would do

map.resources :forums do |forum|
  forum.resources :categories do |cat|
    cat.resources :topics
  end
end

You could add :has_many => :topics but if you need members and/or
collections later its better this way.
