[SOLVED] Rails: render certain pins on a specific page

Rails: render certain pins on a specific page

I would like to render only certain pins of my rails app on a page. Pins has a specific id. And I would like to render for example pin with id: 2 and 3 on a page and render pins with id 4 and 4 on an other page.

So i tried to implement this code on my controller in: app/controller/pin_controller.rb

def mypage
   @pin = Pin.find(2)
   @pin = Pin.find(3)
end

And in my app/views/pins/mypage.html.erb I inserted the app/views/pins/index.html.erb

to make it short it looks like this:

<% @pins.each do |pin| %>
  <%=link_to pin_path(pin) do %>
    <%= pin.description %>
  <% end %>
<% end %>

I have a method error saying that there is no method: each:

undefined method `each' for nil:NilClass

And of course if I get rid of this each method: the page only render one pin from the two pins I want to render.

Any ideas how to fix this?

Solution

You haven't defined @pins anywhere.

def mypage
   @pins = Pin.where(id: [2,3])
end
