Question

I’m looking to take an example of a model (in this case, Book), and render a specific instance of that model by ID.

The model is just a basic scaffold generated model – usual show method;

def show
    @book = Book.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @book }
    end
  end

I’m looking to embed an instance of this inside of the view:

<div class="tab-pane active" id="tab1">
    <%= render :template "books/show", :book => 1 %>
</div>

There’s something I’m doing wrong here, I can tell. But I don’t know where to proceed from here! Any help is really appreciated. I know I need to somehow pass the book ID, but I can’t figure out how to do that. Thanks!

<%= render :template "books/show", :book => 1 %> only renders the partial, it doesn’t load the page.
What you need to do is call the route "books/show/#{book_id}" from an iframe for example.
