Iteration 1

There are **3** points possible in Iteration 1:

1.  Artist Creation (must include all attributes)
2.  Photograph Creation (must include all attributes)
3.  Artist #age_at_death

Use TDD to create a Photograph and an Artist class that respond to the following interaction pattern.

For age_at_death, assume an artist was born and died on the same day.

pry(main)> require './lib/photograph'
#=> true

pry(main)> require './lib/artist'
#=> true

pry(main)> attributes = {
  id: "1",
  name: "Rue Mouffetard, Paris (Boy with Bottles)",
  artist_id: "4",
  year: "1954"
}      

pry(main)> photograph = Photograph.new(attributes)
#=> #<Photograph:0x00007fc2d1050c80...>

pry(main)> photograph.id
#=> "1"

pry(main)> photograph.name
#=> "Rue Mouffetard, Paris (Boy with Bottles)"

pry(main)> photograph.artist_id
#=> "4"

pry(main)> photograph.year
#=> "1954"

pry(main)> attributes = {
  id: "2",
  name: "Ansel Adams",
  born: "1902",
  died: "1984",
  country: "United States"
}

pry(main)> artist = Artist.new(attributes)
#=> #<Artist:0x00007fc2d0a6c080...>

pry(main)> artist.id
#=> "2"

pry(main)> artist.name
#=> "Ansel Adams"

pry(main)> artist.born
#=> "1902"

pry(main)> artist.died
#=> "1984"

pry(main)> artist.country
#=> "United States"

pry(main)> artist.age_at_death
#=> 82

Iteration 2

There are **3** points possible in Iteration 2:

4. Curator Creation (must include all attributes)
5. Curator #add_photograph & Curator #add_artist
6. Curator #find_artist_by_id

Use TDD to create a Curator class that responds to the following interaction pattern:

pry(main)> require './lib/photograph'
# => true

pry(main)> require './lib/artist'
# => true

pry(main)> require './lib/curator'
# => true

pry(main)> curator = Curator.new    
# => #<Curator:0x00007fb3d9111cc0...>

pry(main)> curator.photographs
# => []

pry(main)> photo_1 = Photograph.new({
     id: "1",      
     name: "Rue Mouffetard, Paris (Boy with Bottles)",      
     artist_id: "1",      
     year: "1954"      
})        
# => #<Photograph:0x00007fb3d8ea1cd8...>

pry(main)> photo_2 = Photograph.new({
     id: "2",      
     name: "Moonrise, Hernandez",      
     artist_id: "2",      
     year: "1941"      
})        
# => #<Photograph:0x00007fb3d8e0bfa8...>

pry(main)> curator.add_photograph(photo_1)

pry(main)> curator.photographs
# => [#<Photograph:0x00007fb3d8ea1cd8...>, #<Photograph:0x00007fb3d8e0bfa8...>]

pry(main)> curator.artists

    country: "France"

pry(main)> curator.find_artist_by_id("1")
# => #<Artist:0x00007fb3d8b4ed60...>

Iteration 3

There are **3** points possible in Iteration 2:

7. Curator #photographs_by_artist
8. Curator #artists_with_multiple_photographs
9. Curator #photographs_taken_by_artist_from

Use TDD to update your Curator class so that is supports the following methods:

• photographs_by_artist - This method will return a hash with artists as keys, and an array of their photographs as values.
• artists_with_multiple_photographs - This method returns an Array of names of artists who have more than one photograph
• photographs_taken_by_artists_from(string) - This method takes a String representing a country. It returns an Array of Photographs that were taken by a photographer from that country.

The Curator class should now respond to the following interaction pattern:

pry(main)> require './lib/photograph'
# => true

pry(main)> require './lib/artist'
# => true

pry(main)> require './lib/curator'
# => true

Iteration 4

There are **3** points possible in Iteration 2:

10. Curator #load_photographs && #load_artists
11. Curator #photographs_taken_between
12. Curator #artists_photographs_by_age

Use TDD to add the following methods to your Curator class:

• load_photographs(file) - This method takes a path to a CSV file containing photographs and adds them to the Curator. You may find the included FileIO class useful.
• load_artists(file) - This method takes a path to a CSV file containing artists and adds them to the Curator. You may find the included FileIO class useful.
• photographs_taken_between(range) - This method takes a range and returns an array of all photographs with a year that falls in that range.
• artists_photographs_by_age(artist)- This method takes an Artist object and return a hash where the keys are the Artists age when they took a photograph, and the values are the names of the photographs.

pry(main)> require './lib/curator'

pry(main)> curator = Curator.new
#=> #<Curator:0x00007fd98685b2b0...>

pry(main)> curator.load_photographs('./data/photographs.csv')

pry(main)> curator.photographs_taken_between(1950..1965)
#=> [#<Photograph:0x00007fd986254740...>, #<Photograph:0x00007fd986254678...>]

pry(main)> diane_arbus = curator.find_artist_by_id("3")    

pry(main)> curator.artists_photographs_by_age(diane_arbus)
=> {44=>"Identical Twins, Roselle, New Jersey", 39=>"Child with Toy Hand Grenade in Central Park"}
