authentication - rails authenticate nomethoderror nil for nilClass -
so, i've been having issues 'authenticate' method coming in rspec nomethoderror. below code. i'm borrowing heavily michael hartl's rails tutorial learning rails , rspec.
i have added 'has_secure_password' user model told in hartl's tutorial, , have created user password_digest, method functional. tests going screwy all. wondered if installed rspec wrong, somehow. have followed tutorial tee without error getting in way this. ideas on why occurring?
my user_spec.rb:
require 'spec_helper' describe user before @user = user.new(name: "example user", email: "user@example.com") end subject { @user } { should respond_to(:name) } { should respond_to(:email) } { should respond_to(:password_digest) } { should respond_to(:password) } { should respond_to(:password_confirmation) } { should respond_to(:authenticate) } { should be_valid } describe "when name not present" before { @user.name = ' ' } { should_not be_valid} end describe "name long" before { @user.name = "a" * 51 } { should_not be_valid } end describe "when email format valid" "should valid" addresses = %w[user@foo.com a_us-er@f.b.org frst.lst@foo.jp a+b@baz.cn] addresses.each |valid_address| @user.email = valid_address @user.should be_valid end end end describe "when email format invalid" "should invalid" addresses = %w[user@foo,com user_at_foo.org example.user@foo. foo@bar_baz.com foo@bar+baz.com] addresses.each |invalid_address| @user.email = invalid_address @user.should_not be_valid end end end describe "when email taken" before user_with_same_email = @user.dup user_with_same_email.email = @user.email.upcase user_with_same_email.save end { should_not be_valid } end describe "when password not present" before { @user.password = @user.password_confirmation = " " } { should_not be_valid } end describe "when password doesn't match confirm" before { @user.password_confirmation = "mismatch" } { should_not be_valid } end describe "when password confirm nil" before { @user.password_confirmation = nil } { should be_invalid } end describe "with password that's short" before { @user.password = @user.password_confirmation = "a" * 5 } { should_not be_valid } end describe "return value of authenticate method" before { @user.save } let(:found_user) { user.find_by_email(@user.email) } describe "with valid password" { should == found_user.authenticate(@user.password) } end describe "with invalid password" let(:user_for_invalid_password) { found_user.authenticate("invalid") } { should_not == user_for_invalid_password } specify { user_for_invalid_password.should be_false } end end end and gemfile:

editing instance user such solved issues:
before @user = user.new(name: "example user", email: "user@example.com", password: "foobar", password_confirmation: "foobar") end
in user model you're validating presence of password in spec should pass in password new user object. should valid.
i'm guessing that's reason you're running problems authentication method well.
