Rendering partial from another folder from another partial in Rails 3
提问by aetaur
For example:
I'm have two models: Taskand List. Taskbelongs_toList.
I'm render lists/_form.html.erbpartial within lists/show.html.erb view.
Now I need to render tasks/_fields.html.erbpartial within lists/_form.html.erbpartial:
例如：我有两个模型：Task和List。Taskbelongs_toList. 我lists/_form.html.erb在lists/show.html.erb view. 现在我需要tasks/_fields.html.erb在lists/_form.html.erb部分渲染部分：
<%= render 'tasks/fields' %>
But I get an error ActionView::MissingTemplate
但我收到一个错误 ActionView::MissingTemplate
If I try to render tasks/_fields.html.erbwithin lists/_form.html.erb, everything works.
如果我尝试在tasks/_fields.html.erb内渲染lists/_form.html.erb，则一切正常。
I see two bad ways to solve this problem:
我看到解决这个问题的两种不好的方法：
- Place
_fields.html.erbtolistsfolder - Make a view from
lists/_form.html.erbpartial and try a "Nested Layouts" from http://guides.rubyonrails.org/layouts_and_rendering.html
- 放置
_fields.html.erb到lists文件夹 - 从
lists/_form.html.erb局部创建视图并尝试从http://guides.rubyonrails.org/layouts_and_rendering.html尝试“嵌套布局”
Is there a good way?
有什么好办法吗？

Try this:
尝试这个：
<%= render :partial => 'tasks/fields' %>

If you are sharing things like this, why not put them into a folder like app/views/shared/or directly into app/views/layouts?
如果你正在分享这样的东西，为什么不把它们放到一个文件夹中，app/views/shared/或者直接放入app/views/layouts？

For Rails 5 & above:
对于 Rails 5 及以上版本：
You better use the render without partial like this:
你最好像这样使用没有部分的渲染：
<% render 'tasks/fields' %>
Because the partialcan cause this kind of issues& is not needed any more
因为partial可能会导致此类问题并且不再需要

Based on @ArunKumarArjun but with the new Rails notation:
基于@ArunKumarArjun 但使用新的 Rails 符号：
<%= render partial: 'tasks/fields' %>
