How to change the default path of view files in a Rails 3 controller?
提问by Yuval Karmi
I have a controller called ProjectsController. Its actions, by default, look for views inside app/views/projects. I'd like to change that path for all methods (index, show, new, editetc...) in the controller.
我有一个名为ProjectsController. 默认情况下，它的操作会在app/views/projects. 我想改变这种路径的所有方法（index，show，new，edit等...）在控制器中。
For example:
例如：
class ProjectsController < ApplicationController
#I'd like to be able to do something like this
views_path 'views/mycustomfolder'
def index
#some code
end
def show
#some code
end
def new
#some code
end
def edit
#some code
end
end
Please note I am not changing each method with renderbut defining a default path for all of them. Is this possible? If so, how?
请注意，我没有更改每个方法，render而是为所有方法定义默认路径。这可能吗？如果是这样，如何？
Thank you!
谢谢！

If there's no built-in method for this, perhaps you can override renderfor that controller?
如果没有为此的内置方法，也许您可以覆盖render该控制器？
class MyController < ApplicationController
# actions ..
private
def render(*args)
options = args.extract_options!
options[:template] = "/mycustomfolder/#{params[:action]}"
super(*(args << options))
end
end
Not sure how well this works out in practice, or if it works at all.
不确定这在实践中的效果如何，或者它是否有效。

See ActionView::ViewPaths::ClassMethods#prepend_view_path.
请参阅ActionView::ViewPaths::ClassMethods#prepend_view_path。
class ProjectsController < ApplicationController
prepend_view_path 'app/views/mycustomfolder'

You can do this inside your controller:
您可以在控制器中执行此操作：
def self.controller_path
"mycustomfolder"
end

You can add something like:
您可以添加如下内容：
paths.app.views << "app/views/myspecialdir"
in the config/application.rb file to have rails look in another directory for view templates. The one caveat is that it'll still look for view files that match the controller. So if you have a controller named HomeController with the above config for the views it'll look for something named "app/views/myspecialdir/home/index.html.erb" to render.
在 config/application.rb 文件中，让 rails 在另一个目录中查找视图模板。一个警告是它仍然会寻找与控制器匹配的视图文件。因此，如果您有一个名为 HomeController 且具有上述视图配置的控制器，它将寻找名为“app/views/myspecialdir/home/index.html.erb”的内容来呈现。

If you want to change the default path for all your views at app level, you could do something like following -
如果您想在应用程序级别更改所有视图的默认路径，您可以执行以下操作 -
class ApplicationController < ActionController::Base
before_action :set_views
private
def set_views
prepend_view_path "#{Rails.root.join('app', 'views', 'new_views')}"
end
end
And write all your views in the folder new_viewsfollowing the same directory structure as original.
并new_views按照与原始目录结构相同的目录结构在文件夹中写入所有视图。
