Good afternoon,
Everyone here has been incredibly helpful in their past support of my issues, so I'm hoping that I can ask just a few more as I move along in learning RoR.
I'm generating two grids in a particular view. The first grid displays the top five selling products (as defined by the field, position) and then the last grid displaying the remaining products.
The existing find query is as follows:
@product_grid = Product.find(:all, :order => 'position', :conditions => {:store_id => current_store.id})
After retrieving all of the information for the relevant products, the array is passed over to a view that displays it as follows:
<% @product_grid.in_groups_of(5, false) do |row_products| %>
<% for product in row_products %> <%= product.name%>
<% end %>
How would one go about limiting this loop to only display the first 5 products that were retrieved based on position? Additionally, how would one use the same grid format to display every product that has a position greater than 5?
How about:
first_five = @product_grid[0..4] everything_else = @product_grid[5..@product_grid.length]
