Question

I’m pretty new to rails and it’s the first time I’m actually using authlogic + acl9. I followed the default installation steps for both plugins.

So far everything works great, but I have trouble to find an elegant solution for this problem:

Let’s say I have a model class called Products. When creating a new Product object I assign the current_user as the owner:

current_user.has_role! :owner, @product

I registered a second user and made sure that this part worked.

In the products controller I have an index method, simply returning all products:

def index
  @products = Products.all
end

My question is: How do I call the find method on Products in order to get just those products where the current_user is the :owner?
So I using the acl9 interface that would mean:

@product.accepts_role?(:owner, current_user)

One possibility probably would be to first retrieve all products and then create a new array with just the current_user ones. so maybe like this:

@products = []
products = Products.all
products.each do |p|
  @products << p if p.accepts_role?(:owner, current_user)
end 

This solution seems pretty wasteful. So what’s the right way to do it?

Thanks everyone!

Answer 1

how about doing all in one query:

@products = Product.all.select { |p| p.accepts_role?(:owner, current_user)}

but the idea remains as proposed by yourself
