如何在Rails 3控制器中更改视图文件的默认路径? [英] How to change the default path of view files in a Rails 3 controller?

问题描述

我有一个名为ProjectsController的控制器.默认情况下，其操作会在app/views/projects中查找视图.我想为控制器中的所有方法(index，show，new，edit等...)更改该路径.

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, edit etc...) in the controller.

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

请注意，我没有使用render更改每个方法，而是为所有方法定义了默认路径.这可能吗?如果可以，怎么办?

Please note I am not changing each method with render but defining a default path for all of them. Is this possible? If so, how?

谢谢！

推荐答案

如果没有内置方法，也许您可​​以为该控制器覆盖render?

If there's no built-in method for this, perhaps you can override render for that controller?

class MyController < ApplicationController
  # actions ..

  private

  def render(*args)
    options = args.extract_options!
    options[:template] = "/mycustomfolder/#{params[:action]}"
    super(*(args << options))
  end
end

不确定这在实践中的效果如何，或者根本无法实现.

Not sure how well this works out in practice, or if it works at all.
