Topic: Class scope question
I hope this the right place. My question is more ruby than rails. When I am writing models sometimes it is nessisary for me to use self and other times I don't need to. I was hoping some one could enlighten me on the subtleties that I am not seeing. They seem the same to me. Let me give you an example.This is a method in one of my models
def fetch_articles current_feed = get_rss_feed( 5 ) debugger if current_feed.class == Feedzirra::Parser::RSS self.status = true else self.status = false end self.save if status current_feed.entries.each do |article| unless Article.array_of_article_urls.include?(article.url) a = Article.new(title: article.title, content: article.content, source: article.url, clicks: 0) a.title ||= article.summary a.content ||= article.summary a.save end end end end
Before I didn't have those self's it wouldn't persist the changes in the database then when I added them it worked.yet a little later this one works fine without self.
def display_status if status "<span class='label label-success'>Success</span>" else "<span class='label label-important'>Fail</span>" end end
