Could anyone explain params
in Rails controller: where they come from, and what they are referencing?
def create
@vote = Vote.new(params[:vote])
item = params[:vote][:item_id]
uid = params[:vote][:user_id]
@extant = Vote.find(:last, :conditions => ["item_id = ? AND user_id = ?", item, uid])
last_vote_time = @extant.created_at unless @extant.blank?
curr_time = Time.now
end
I would like to be able to read this code line-by-line and understand what's going on.
