Error - Template is missing, unable to have 2 show views for the same posts

问题

This is a follow up question to: Rendering different views in one action

The error I am getting is:

Template is missing

Missing template items/show, application/show with {:locale=>[:en], :formats=>[:html], :handlers=>[:erb, :builder, :coffee]}.

It should be noted, that I copied the show.html.erb file to two files show_with_edit.html.erb and show_with_star.erb, and deleted show.html.erb to avoid duplicates.

My Code in posts_controller.rb

def show
  if signed_in?
    show_signed_in
  else
    show_not_signed_in
  end
end  

def show_signed_in
  #add methods here
  @post = Post.find(params[:id])

  respond_to do |format|
    format.html # show_with_edit.html.erb
    format.json { render json: @post }
  end
  render 'show_with_edit'
end

def show_not_signed_in
  #add methods here
  @post = Post.find(params[:id])

  respond_to do |format|
    format.html # show_with_star.html.erb
    format.json { render json: @post }
  end
  render 'show_with_star'
end

I am aware that for now the two different views are identical, I just put there different text for now. Once I have this nailed down I'll add to each view its own methods and content etc.

回答1:

You've put render in the wrong places.

def show_signed_in
  #add methods here
  @post = Post.find(params[:id])

  respond_to do |format|
    format.html # show_with_edit.html.erb
    format.json { render json: @post }
  end
  render 'show_with_edit'
end

should be

def show_signed_in
  #add methods here
  @post = Post.find(params[:id])

  respond_to do |format|
    format.html { render 'show_with_edit' }
    format.json { render json: @post }
  end
end

Note the render that is moved to the format.html block.

The same applies for show_not_signed_in.

回答2:

please check your route.rb file is properly written , eg: consider following

  resources :posts
     collection 
       get :show_not_signed_in
       get :show_signed_in
    end 

collection you write the method that is get or post
