Why am I getting syntax error, unexpected '}', expecting keyword_end with scope?

I'm a beginner, and have been learning Ruby on Rails for about 10 weeks now. When trying to run an RSpec test on one of my models, I get this error:

rb:4: syntax error, unexpected '}', expecting keyword_end

It looks like my brackets are closed and I have ended properly. 

class Item < ActiveRecord::Base
  belongs_to :list

  scope :created_after, -> (7.days.ago) { where("item.created_at > ?", 7.days.ago) }

 end

The purpose of the scope is to be able to differentiate items that are older than 7 days from items written in the last week.

Here is my schema for this the list model:

  create_table "items", force: true do |t|
    t.string   "body"
    t.integer  "list_id"
    t.boolean  "done",       default: false
    t.datetime "created_at"
    t.datetime "updated_at"
  end`

I've looked at the Rails Guides and have searched repeatedly but can't find anything that tells me my current syntax is wrong. Any ideas?

The issue is with how you have defined your lambda. As you just started learning Ruby & Rails I would recommend you read this article to understand what lambdas are, how they operate and what the syntax is. The code in round brackets should be a variable name that can be passed into the lambda rather than a definition of a date. E.g your code:

scope :created_after, -> (7.days.ago) { where("item.created_at > ?", 7.days.ago) }

Should be:

scope :created_after, -> (date) { where("item.created_at > ?", date) }

That way you can create queries on Items like this:

new_items = Item.created_after(7.days.ago) # or..
newer_items = Item.created_after(3.days.ago) # or...
new_done_items = Item.where(done: true).created_after(7.days.ago) # etc
