Having different database sorting order (default_scope) for two different views
- by Juniper747
In my model (pins.rb), I have two sorting orders:
default_scope order: 'pins.featured DESC' #for adding featured posts to the top of a list
default_scope order: 'pins.created_at DESC' #for adding the remaining posts beneath the featured posts
This sorting order (above) is how I want my 'pins view' (index.html.erb) to look. Which is just a list of ALL user posts.
In my 'users view' (show.html.erb) I am using the same model (pins.rb) to list only current_user pins. HOWEVER, I want to sorting order to ignore the "featured" default scope and only use the second scope:
default_scope order: 'pins.created_at DESC'
How can I accomplish this? I tried doing something like this:
default_scope order: 'pins.featured DESC', only: :index
default_scope order: 'pins.created_at DESC'
But that didn't fly...
UPDATE
I updated my model to define a scope:
scope :featy, order: 'pins.featured DESC'
default_scope order: 'pins.created_at DESC'
And updated my pins view to:
<%= render @pins.featy %>
However, now when I open my pins view, I get the error:
undefined method `featy' for #<Array:0x00000100ddbc78>

def edit
@pin = current_user.pins.find_by_slug!(params[:id])
end
Finally, on my index.html.erb I have:
<%= render @featured_pins %>
