Question

出于此问题的原因，我需要在创建图像时使用JSON进行响应：

<%=
  raw({
    ...
    :url => @image.url(:width => @width, :height => @height),
    :edit_link => render({:state => :image_edit_table_cell, :template_format => :html}, @image),
    # btw, I've also tried passing :format => :html
    :delete_link => link_to_destroy_image(@image, :remote => true, :path => url_for_event(:destroy, :image_id => @image)),
    ...
  }.to_json)
%>

然而，在那个JSON中，我想要包含一些非常精美的HTML。为了包括它，我渲染一个状态/视图（正如你在:edit_link部分中看到的那样）。这是小部件的image_edit_table_cell.html.haml视图：

= link_to_edit_image @image, :remote => true
# ... doesn't really matter - as long as you know this is html.haml

但是，当我创建图像并呈现JSON时，我收到Missing template错误：

ActionView::Template::Error (Missing template cell/rails/image_edit_table_cell with {:handlers=>[:builder, :rjs, :rhtml, :erb, :haml, :rxml], :locale=>[:en, :en], :formats=>[:json]} in view paths "/home/ramon/source/unstilted/app/widgets", "/home/ramon/source/unstilted/app/widgets/layouts" and possible paths image/table/image_edit_table_cellapplication/image_edit_table_cellapotomo/widget/image_edit_table_cellcell/rails/image_edit_table_cell):
    6:     :caption => @image.caption || "",
    7:     :text_tag => @image.text_tag(:width => @width, :height => @height),
    8:     :url => @image.url(:width => @width, :height => @height),
    9:     :edit_link => render({:state => :image_edit_table_cell, :template_format => :html}, @image),
    10:     :delete_link => link_to_destroy_image(@image, :remote => true, :path => url_for_event(:destroy, :image_id => @image)),
    11:     :success => true
    12:   }.to_json)
  app/widgets/image/table_widget.rb:37:in `image_edit_table_cell'

  app/widgets/image/table_widget.rb:16:in `add_image'
  app/widgets/image/uploader_widget.rb:22:in `upload'

似乎问题在于，因为我是从JSON文件渲染它，所以它不知道要查找HTML文件（因此它所寻找的格式是json。这就是你看到的原因上面第一段代码中的:template_file => :html选项（我从here获得了该选项）。

我正在使用这些宝石：

'rails'，'3.0.10'
'cells'，'3.6.2'
'apotomo'，“1.1.2”

Answer 1

显然，这是一个Rails问题，而不是Apotomo问题。这answer为我做了！关键是在渲染html视图之前在视图文件中设置格式：

<% self.formats = ["html"] %>

Apotomo：你如何从另一种格式的另一种视图呈现HTML格式的状态/视图？
