Now what I am trying to do is list all the ingredients for a Stack
(using standard params[:id]). It seems that I cannot pass multiple
product_ids (but one id work fine!) to get the ingredients listing.
Here's a partial code from my controller :
=== START ===
def stack
begin
@stack = Stack.find(params[:id])
render :template => "public/stack_#{@lang}"
rescue ActiveRecord::RecordNotFound
logger.error("Attempt to access invalid stack #{params[:id]}")
flash[:notice] = "Désolé, cette formule est introuvable."
redirect_to :action => :index
end
end
=== END ===
Any help would be appreciate and I can provide more information if my
request isn't clear enought.
product.ingredients is an array, you could reference
product.ingredients[0].name or you could iterate the array using
product.ingredients.each. Another useful construct is
product.ingredients.map(&:name) which will give you an array of
ingredient names.
In all of this don't forget to watch out for a product with no
ingredients (product.ingredients is nil in this case) which can give
you run-time errors if you have not caught them. The same applies to
stack.products.
I wonder whether it would be useful for you to run through some basic
Ruby tutorials to get a bit more grounding on the basics of Ruby.
