错误 - 模板丢失，同一帖子不能有 2 个显示视图 [英] Error - Template is missing, unable to have 2 show views for the same posts

问题描述

这是一个后续问题:在一个动作中呈现不同的视图

我得到的错误是:

Template is missing

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

需要注意的是，我将 show.html.erb 文件复制到两个文件 show_with_edit.html.erb 和 show_with_star.erb>，并删除了 show.html.erb 以避免重复.

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.

我在 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

我知道现在两个不同的视图是相同的，我现在只是在那里放了不同的文本.一旦我确定了这一点，我将向每个视图添加它自己的方法和内容等.

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.

推荐答案

你把渲染放在了错误的地方.

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

应该是

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

注意移动到 format.html 块的 render.

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

同样适用于 show_not_signed_in.

The same applies for show_not_signed_in.
