Render a different view from any controller in Rails 4

Question

I have two models, book and course. In the books_controller I have a search method to find books by their ISBN.

def searchbook
  @searchedbook = Book.find_by_isbn(params[:q])
end

There is an input field in the index page that displays all the books. So my index.html.erb has this:

=form_tag({controller: "books", action: "searchbook"}, :method => :get) do
 .search_field
   %p
    Search Using ISBN:
   =text_field_tag :q
   =button_tag 'Go' , class: 'search-button' , type: :submit
%br

I have added this to my routes:

match 'searchbook', to: 'books#searchbook', via: :get

I just realized that my searchbook.html.erb is exactly the same as the show.html.erb. How can I get show.html.erb to render the results from searchbook

As you have same action for searchbook page view and form submit, so you need to check params q at URL searchbook action. So, whenever you submit the form, it will append parameter q and @searchedbook

def searchbook
  @searchedbook = Book.find_by_isbn(params[:q]) if params[:q].present?
end

At searchbook.html.erb

-if @searchedbook
  = render "show" # render the show partial

I just got this error: 'Missing partial books/_show, application/_show with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :haml, :jbuilder]}. Searched in: * "/Users/qqq/.rvm/gems/ruby-2.1.3/gems/web-console-2.0.0/lib/action_dispatch/templates" * "/Users/qqq/Documents/com381/bookiit/app/views" ' I wonder if it means that I should rename my show to _show

@neesop, you need a erb partial file at books directroy like _show.html.erb. If a have a file like show.html.erb than rename it to _show.html.erb.

This is what partials are designed for.

Use partials in searchbook.html.erb like render "show".
