Question

I’m trying to loop through the most recent “Articles” – say, 10 most recently posted within last 30 days.

Should I be creating a method in my article model something like follows:

models/articles.rb

def recent
  self.where('created_at > ?', Time.now-30.days.ago)
end

And then calling it in my views?

views

@articles.each do |article|
   link_to article.title, Article.recent    
end

This of course, does not work.

If this has been answered (maybe I was using wrong search terms – new to stackoverflow), direction is appreciated!

Answer 1

I think this should be in a method, but a class method. I personally prefer methods over scopes for this sort of thing.

def self.recent
  where('created_at > ?', Time.now-30.days.ago).order("created_at desc").first(10)
end

In your controller, you can set @recent_articles with

@recent_articles = Article.recent

view you will then do

@recent_articles.each do |article|
  link_to article.title, article_path(article) # use your proper route method here.
end
