错误 - 模板丢失，无法为同一帖子显示2个视图 [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： Rails中同一数据库的两个单独显示视图

我得到的错误是：

 模板缺失
 
缺少模板项目/ show，application / show with {：locale => [：en]，：formats => [： html]，：handlers => [：erb，：builder，：coffee]}。 
  

应该注意，我复制了 show.html.erb 文件复制到两个文件 show_with_edit.html.erb 和 show_with_star.erb

我的代码在 posts_controller.rb

  def show 
如果signed_in？ 
 show_signed_in 
 else 
 show_not_signed_in 
 end 
 end 
 
 def show_signed_in 
 #add方法在这里
 @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方法在这里
 @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一样的，我现在只是把不同的文本。一旦我有了这个钉子，我会添加到每个视图自己的方法和内容等。

解决方案

在错误的地方。

  def show_signed_in 
 #add方法在这里
 @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 
  

应为

  def show_signed_in 
 #add方法在这里
 @post = Post.find（params [：id]）
 
 respond_to do | format | 
 format.html {render'show_with_edit'} 
 format.json {render json：@post} 
 end 
 end 
  pre> 
 
 
请注意将 render 移动到format.html块。
 
 
 
这同样适用于show_not_signed_in。
 
This is a follow up question to: Two separate show views for the same database in Rails

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.
解决方案
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.
