How to use form_for with customized route?

The custom routing:

resources :blog, controller: 'posts'

How do I rewrite this line <%= simple_form_for(@post, blog_path) do |f| %> to get rid of the below error?

TypeError in Posts#edit
ActionView::Template::Error (no implicit conversion of Symbol into Integer)

I also tried <%= simple_form_for(blog_path(@post)) do |f| %>, which gets rid of the error, but then if I want to edit the form the inputs are emptied of their saved data.

posts_controller

  def new
    @post = Post.new
    respond_with(@post)
  end

  def edit
  end

  def create
    @post = Post.new(post_params)
    if current_user.admin
      @post.save
      respond_with(@post)
    else
      flash[:success] = 'Get out of here.'
      redirect_to root_url
    end
  end

It can take a hash options, including url, so something like this:

Edit: changed blog_path to blogs_path. The blog_path is the show action, not the create action and therefore requires an id (and isn't a post path anyway). Try it out this way.

<%= simple_form_for(@post, url: blogs_path) do |f| %>

Don't know if this applies, but a really cool feature I found the other day was .becomes - where you can change the "class" of your object so that Rails treats it in a different way:

This can be used along with record identification in Action Pack to allow, say, Client < Company to do something like render partial: @client.becomes(Company) to render that instance using the companies/company partial instead of clients/client.

So...

If you had a Blog model, and wanted each @post to be treated as such (again, I don't know if this is your setup at all), you could do the following:

<%= simple_form_for @post.becomes(Blog) do |f| %>

I'll delete if inappropriate; it's come in handy quite a lot for me.

Update

If you'd like your posts_path to be blog (IE url.com/blog/1), you'll want to look at using the path option for the routes generator:

#config/routes.rb
resources :posts, path: "blog", as: :blog # -> url.com/blogs/2
