Rails 3 assocations

Question

I am trying to get the user_id of the user that is logged in. So a user will create a blog post and it will capture the id of the user when creating the blog post.

I know how to do this using nested resources but how can I get the user_id when creating a new blog post without nested resources?

the routes would look like this

resources :blogs

I also tried adding hidden field to blog form _blog.html.erb

<%= f.hidden_field :site_id, :value => @blog.site_id %>

The association is set up correctly I am just trying to see how I can get the user_id without nested resources. Any suggestions?

Answer 1

Pull the user id off the currently logged in user in the BlogsController#create method.

Example (Note that how you access the user_id will depend on how you're doing authentication)

class BlogsController < ApplicationController
  def create
    @blog = Blog.new params[:blog]
    @blog.user_id = current_user.id
    if @blog.save
      ...
    end
  end
end

Answer 2

if you are using devise/authlogic for authentication then you can easily get user_id using current_user method provided
