Rails loop through objects in view

I have the following associations:

class Shop < ApplicationRecord
  has_many :opening_hours
end

class OpeningHour < ApplicationRecord
  belongs_to :shop
end

I'm looping through shops inside a view like this:

<% @shop.each do |shop|%>
  <%= shop.street %>
  <%= shop.city %>
<% end %>

I have an action inside a controller, from which I want to check if a shop is open or not:

def open
  @open = OpeningHour.where(day: Time.zone.now.wday).where('? BETWEEN opens AND closes', Time.zone.now).any?
end

I would like to show if the shop is open or not with something like this:

<% if %>
  <span style="color: black">Open</span>
<% else %>
  <span style="color: lightgrey">Close</span>
<% end %>

How can I add the above if and else to the loop in order to show if each shop is open or close?

Assuming opening_hours belong to the shop model

class Shop
  def open?
    opening_hours.where(day: Time.zone.now.wday).where('? BETWEEN opens AND closes', Time.zone.now).any?
  end
end

Then in the view

<% if shop.open? %>
    <span style="color: black">Open</span>
<% else %>
    <span style="color: lightgrey">Close</span>
<% end %>
