#1.
|
|
# - Kontrollera gems (sinatra, slim, sqlite). Kommer du behöva sessions? Troligen ej, ska endast utföra CRUD på databasen.
|
|
# - Se hur Slimfiler är organierade i mappstrukturen. Följer det REST? Hur kallar man på en slimfil i en mapp?
|
|
# [x]
|
|
|
|
#2. Starta upp applikationen och inspektera koden i Chrome (högerklick>inspect). Hur ser länkarna ut? Finns de som routes i app.rb? [x]
|
|
|
|
#3. När vi klickar på ett album vill vi även se artisten (inte bara id). Gör ett andra anrop till db och skicka med i locals. [x]
|
|
|
|
#4. Skapa en sida där vi lägger till nya album för tex Artisten ACDC (ArtistId 1). Hitta gärna på nya namn på skivorna [x]
|
|
|
|
#5. Skapa funktionalitet för att ta bort album [x]
|
|
|
|
#6. Skapa funktionalitet för att uppdatera artistinformation [x]
