Ruby, Sinatra selector for specific parameter

Question

ruby

There is a standard Sinatra blog code:

post '/articles' do
  article = Article.new(params[:article])

  if article.save
    redirect '/articles'
  else
    redirect '/articles/new'
  end
end

The form has, respectively: id, title, content.
How to immediately apply the UpCase parameter to the title in such code, so that the result would be sent to the database?

Answer 1

If it's an ActiveRecord, then you can use the before_save callback: api.rubyonrails.org/classes/ActiveRecord/Callbacks.html
Like this:

class Article < ActiveRecord::Base
  before_save :upcase_title

  private

  def upcase_title
    self.title.upcase!
  end
end
