Ruby Helpers 2

To remember:

• Rails will change plurals when generating models
• Do not use convention words for other stuff, you will just confuse yourself!

New:

• Use block to have closing tags
• Form helper: adds more stuff, including the authenticity token
• label_tag: first argument = for and second argument=content
• for inputs, each type has a different tag. First argument = name (and id), 2nd argument = value (prepopulate), 3rd hash = attributes of the element (for example to change id to a non conventional name)
• HTML default behavior is "gets", but Rails is "post"
• find_by: same as where but gives the first instance directly. Also find method is the same but use directly a number (for id). If the id does not exist, first method gives nil, but find gives an exception (ActiveRecord not found = 404 error in production)
• resources :movies = gives all 7 routes
• Default behavior can always be overwrite
• Using conventions makes everything EASIER!
