Hi, I see that nobody knows how to do better way.
So maybe someone could suggest different model design that I can do @category.active And just to avoid calling this self.merchant_categories.find_by_category_id(id).active def active self.merchant_categories.find_by_category_id(id).active end instead to call self.merchant_category.active Thanks, Tod Tod Tod wrote: > 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.
