导轨：一页上有多个控制器动作

Question

i got a simple rails app for browser bookmarks.
image here
a bookmark, seen on the top, is a folder that contains the subcategory folders in the left sidebar.
when clicking a folder on the left one gets the bookmarks listing of the folder. ie a bookmarks#index with params. same is folder#index with params on the left and top. how can i render all the 3 controller action on one page?

Answer 1

Well you can definitely render to a common page from different actions, see the example:- in bookmarks_controller.rb

def index
  #do your stuffs
  render "path_of_comman_page",locals: {x: "foo", y: "bar"}
end

in folder_controller.rb

def index
  #do your stuffs
  render "path_of_comman_page",locals: {x: "foo", y: "bar"}
end

So here by you will be able to access all locals variable at your comman page. like x, y path_of_comman_page can be for example /bookmarks/listings which means you are rendering data to bookmarks controller listings.html.erb

Alternative it can be done by common partial for example

def index
  #do your stuffs...
  respond_to do |format|
    format.html { render partial: "listings/listing", locals: {x: "foo", y: "bar"}}
  end
end

Answer 2

actually i want it like this, somehow with js. maybe it's possible with a controller too ... folders/index.haml

.container_top
- @folders.each do |f|
  - if f.is_rootparent?
    -# send ajax to fetch subcategory folders!
    =link_to folder_path(parent: f), remote: true do
      .bookmark_vertical
        %p = f.title
.container_left
  #appendsubcategoryfoldershere
