Hi and thanks,
yes this works Shop.find(2).shop_categories.find_by_category_id(10)
In shop_categories table I have field 'active' to mark that a category
is visible/active for the shop.
So what is the best way to retrieve this value for shop's category?
In Category model I have defined 'active' so I can fetch with
@category.active or
@categories.each do |category|
<%= category.name %>
<%= category.active %>
end
def active
self.merchant_categories.find_by_category_id(id).active
end
I know that this is not so good solution, but I could not figured out
over way to get this value. It is realy over kill for server. And It
would get harder if there are more values that I need to keep in
merchant_categories.
Is there a better way to do it?
