Michael Hartl Tutorial Chapter 6 - Syntax error - ruby-on-rails

Question

I'm working on Michael Hartl's Tutorial. I'm on Chapter 6. I am up to user validation. The code below is what I was told to use, but it doesn't work. I get the error message syntax error, unexpected end-of-input, expecting keyword_end (SyntaxError). I don't see a syntax error. Any suggestions?
require 'spec_helper'
describe User do
before do
#user = User.new(name: "Example User", email: "user#example.com")
end
subject { #user }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should be_valid }
describe "when name is not present" do
before { #user.name = " " }
it { should_not be_valid }
end
describe "when email is not present" do
before { #user.email = " " }
it { should_not be_valid }
end
describe "when name is too long" do
before { #user.name = "a" * 51 }
it { should_not be_valid }
end
describe "when email format is invalid" do
it "should be invalid" do
addresses = %w[user#foo,com user_at_foo.org example.user#foo.
foo#bar_baz.com foo#bar+baz.com]
addresses.each do |invalid_address|
#user.email = invalid_address
#user.should_not be_valid
end
describe "when email format is valid" do
it "should be valid" do
addresses = %w[user#foo.COM A_US-ER#f.b.org frst.lst#foo.jp a+b#baz.cn]
addresses.each do |valid_address|
#user.email = valid_address
#user.should be_valid
end
describe "when email address is already taken" do
before do
user_with_same_email = #user.dup
user_with_same_email.email = #user.email.upcase
user_with_same_email.save
end
it { should_not be_valid }
end
end

Answer 1

I recommend that you indent your code, that way it'll be much more obvious where end keywords should go (and you'll see immediately that you're missing one). (Hartl does throughout the book.)
For example:
require 'spec_helper'
describe User do
before do
#user = User.new(name: "Example User", email: "user#example.com")
end
subject { #user }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should be_valid }
describe "when name is not present" do
before { #user.name = " " }
it { should_not be_valid }
end
end
If the indentation doesn't match up anywhere, it should jump out at you, then you'll know there's a problem.

require 'spec_helper'
describe User do
before do
#user = User.new(name: "Example User", email: "user#example.com")
end
subject { #user }
it { should respond_to(:name) }
it { should respond_to(:email) }
it { should respond_to(:password_digest) }
it { should be_valid }
describe "when name is not present" do
before { #user.name = " " }
it { should_not be_valid }
end
describe "when email is not present" do
before { #user.email = " " }
it { should_not be_valid }
end
describe "when name is too long" do
before { #user.name = "a" * 51 }
it { should_not be_valid }
end
describe "when email format is invalid" do
it "should be invalid" do
addresses = %w[user#foo,com user_at_foo.org example.user#foo.
foo#bar_baz.com foo#bar+baz.com]
addresses.each do |invalid_address|
#user.email = invalid_address
#user.should_not be_valid
end
end # you've missed it
end # and this one
describe "when email format is valid" do
it "should be valid" do
addresses = %w[user#foo.COM A_US-ER#f.b.org frst.lst#foo.jp a+b#baz.cn]
addresses.each do |valid_address|
#user.email = valid_address
#user.should be_valid
end
end #
end # and two more
describe "when email address is already taken" do
before do
user_with_same_email = #user.dup
user_with_same_email.email = #user.email.upcase
user_with_same_email.save
end
it { should_not be_valid }
end
end

In Ruby, do .. end specifies a block. It goes like:
... do
.. Some Code Here ...
end
You should indent your code and have better look at the missing end.
In general, Its a convention in Ruby to use 2 spaces Or a tab character with length of 2 spaces to indent your code.
