Rack Routes and GET Params Lab
We've provided the code for a basic list of items. Now it's your turn to extend it. Do you work in app/application.rb
.
Vocabulary Word: "Route"
In applications built on Rack, we use the noun "route" to to refer to a path that the application has a special response to.
Thus the /shoes
"route" shows information about shoes. The /profile
"route" shows information about the logged-in user. The /logout
route does something to delete some information that let the server know the user was logged in.
Instructions
Create a new class array called
@@cart
to hold any items in your cartCreate a new route called
/cart
to show the items in your cartCreate a new route called
/add
that takes in aGET
param with the keyitem
. This should check to see if that item is in@@items
and then add it to the cart if it is. Otherwise give an error
