How to render partial.js in rails 3
提问by Julian Mann
Using rails3 - I have a project with many tasks. I want to use javascript to build the UI for each task. I figured I could display those tasks on the projects show page by rendering a javascript partial for each. I can't get 'tasks/show' to see tasks/show.js.erb Any ideas?
使用 rails3 - 我有一个有很多任务的项目。我想使用 javascript 为每个任务构建 UI。我想我可以通过为每个任务渲染一个 javascript 部分来在项目显示页面上显示这些任务。我无法通过 'tasks/show' 来查看 tasks/show.js.erb 有什么想法吗？
In projects/show.html.erb
在项目/show.html.erb
<div id="tasks">
<%= render(:partial => "tasks/show", :collection => @project.tasks) %>
</div>
tasks/show.js.erb
任务/show.js.erb
$("tasks").append(new TaskWidget(task.id))
I get the errors
我得到了错误
ActionView::MissingTemplate in Projects#show
Missing partial tasks/show with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html], :locale=>[:en, :en]} in view paths .... around line #13
Thanks
谢谢

You can try this. Instead of have a Javacript partial you can make an html one _show_js.html.erband surround your JS code with the html <script>tag.
你可以试试这个。您可以制作一个 html_show_js.html.erb并用 html<script>标记包围您的 JS 代码，而不是使用 Javacript 部分。
<script type='text/javascript'>
$("tasks").append(new TaskWidget(task.id))
</script>
and,
和，
<div id="tasks">
<%= render(:partial => "tasks/show_js", :collection => @project.tasks) %>
</div>

To make it work I needed to add the format:
为了使它工作，我需要添加格式：
<script>
<%= render(:partial => 'shared/topmenujs', :formats => [:js] ) %>
</script>

Try:
尝试：
render :partial => "tasks/show.js"
渲染：部分=>“任务/show.js”

Well I don't know if is the same issue, but I went through a similar thing with rails 3. I had for example a partial view in app/views/invoices/_select.html.erband I was able to render in a view with
好吧，我不知道是否是同样的问题，但我在 Rails 3 中经历了类似的事情。例如，我有一个局部视图app/views/invoices/_select.html.erb，我能够在视图中渲染
<%= render :partial => "invoices/select" %>
<%= render :partial => "发票/选择" %>
with out any problem and if in the controller I place
没有任何问题，如果在控制器中我放置
render :partial => "invoices/select"
渲染：部分=>“发票/选择”
I was able to opened the action in the browser, the problem arise when I try to call the action from an ajax call, then I get the ActionView::MissingTemplateerror. The only way I found to solved was to rename the view to _select.rhtmland then every thing works fine.
我能够在浏览器中打开该操作，当我尝试从 ajax 调用中调用该操作时出现问题，然后ActionView::MissingTemplate出现错误。我发现解决的唯一方法是将视图重命名为_select.rhtml，然后一切正常。

The problem is that in Rails 3 the render from the .js file will only look for files in the form of show.js.erb or show.erb
问题在于，在 Rails 3 中，.js 文件的渲染只会查找 show.js.erb 或 show.erb 形式的文件
To get around this, you would either need to create a _show.js.erb file, but since that sort of defeats the purpose of partials, you could alternatively just rename the show.html.erb file to show.erb
为了解决这个问题，您要么需要创建一个 _show.js.erb 文件，但由于这种方式违背了部分的目的，您也可以将 show.html.erb 文件重命名为 show.erb
This is probably bad practice, though, to make a standard controller action without a type ending (e.g. show.erb)
但是，这可能是一种不好的做法，即制作没有类型结尾的标准控制器操作（例如 show.erb）
What I would do if I were you is rename your partial something like _tasks.erb instead of _show.html.erb, and then if you needed a tasks/show.html.erb you could just render the _tasks partial inside of that view.
如果我是你，我会做的是将你的部分重命名为 _tasks.erb 而不是 _show.html.erb，然后如果你需要一个 tasks/show.html.erb，你可以在该视图中渲染 _tasks 部分。
