A web application is being created with rails.
Like YouTube, I want to create a screen with thumbnails arranged,
I want to call a partial template with render partial:
If i use a variable in the plate, it will be "NameError in Dashboard # index".
The following error screen is displayed.
Applicable source code▼/app/views/dashboard/index.html.haml
= render 'layouts/hedder'
#content
.main
= render 'layouts/page_top'
.dashboard
= image_tag "cover", class: 'cover-img', alt: ""
#info
.popularity
% h2.heading popular videos
% ul.movie-box
= render partial: 'layouts/movie-box', collection: @chapter▼/chapter-tube/app/views/layouts/_movie-box.html.haml
% li.movie-box--list
= link_to "#" do
= image_tag "http://img.youtube.com/vi//sddefault.jpg", class: 'movie-box--list--thumb', alt: "# {chapter.title}"
.chapter-title
= chapter.title
.chapter-pray-time 00:30▼/chapter-tube/app/controllers/dashboard_controller.rb
class DashboardControllerCheck if the variable doesn't pass well to the render destination

I tried many things with reference to this article, but the error content did not change, so
I want you to point out!

Answer # 2
In error message, chapter is incorrect @chapter It may be.
Is the chapter used in _movie-box.html.haml the same as @chapter in the calling index? Is it different?
If it is the same, you can use @chapter.
If it's different, it's supposed to be crossed, but how was it?
