# Instance variables in models 
# recently i came across code where a friend of mine had written  a lot code in models like its below  ( without any attr_reader or accessor ) , is this ok or just plain useless,

  def coordinates
    @coordinates = [latitude, longitude]
  end

# should we do  something like below make more sense 

  def coordinates

- No methods more than 10 lines
- Use database migrations
- after committing a db migration, don't change it. Just add Another migration 
- Thin Controllers, Avoid sharing more than one or two instance variables b/w controllers and views
- use REST at all times
- Use one type of http request per action, do not use "request.post?" type methods.
- Avoid using comments. If unclear, Refactor.
- use "h" in views, to escape everything 
- do not use abbreviations for variable names  
- follow naming conventions don't use variable names like photoalbum use photo_album instead
