ruby on rails tutorial section 3.2 rspec testing error

阅读更多关于 ruby on rails tutorial section 3.2 rspec testing error

recently started the RoRTute by Michael Hartl, getting stuck trying my first rspec test in section 3.2, at this point the test is meant to fail but all i get are errors which I'm having a hard time interpreting. I've had a look around but not getting much luck finding a similar error and/or solution. I am brand new to programming and ruby/rails. Any help would be greatly appreciated, thank you! terminal error output Macintosh:sample_app rails$ bundle exec rspec spec/requests/static_pages_spec.rb /Users/rails/.rvm/gems/ruby-2.0.0-p247@railstutorial_rails_4_0/gems/selenium-webdriver-2.0.0/lib

I'm following along with the rails tutorial. I'm on ch. 6 and I'm getting a strange error with SQLite3 (for the record, I'm using sqlite version 1.3.10 and the tutorial uses 1.3.9) I don't get an error when I run rake db:migrate, but when I run the migration for the test environment, here's what I get: $ bundle exec rake test:models rake aborted! ActiveRecord::PendingMigrationError: Migrations are pending. To resolve this issue, run: bin/rake db:migrate RAILS_ENV=test sample_app/test/test_helper.rb:3:in `<top (required)>' sample_app/test/models/user_test.rb:1:in `require' sample_app/test

问题 I'm going through Michael Hartl's Railstutorial and I am stuck on Exercise 9.6.2. I searched online and used this code in my Sessions Helper: module SessionsHelper def sign_in(user) session[:user_id] = user.id self.current_user = user end def current_user=(user) @current_user = user end def current_user @current_user ||= User.find(session[:user_id]) if session[:user_id] end def signed_in? !current_user.nil? end def sign_out session[:user_id] = nil self.current_user = nil end end I found it

Do I need a “Users” controller when using Devise in Rails

阅读更多关于 Do I need a “Users” controller when using Devise in Rails

问题 I am a Rails newbie. I am working on a small Rails4 project trying to improve my skills. I am loosely following M.Hartl's tutorial. As per the tutorial a custom user authentication is built. However I would like to use Devise for User authentication. Do I still need to have a Users controller as in the tutorial? In which cases should I use/not use a Users controller when already using Devise? Concerning the tutorial, do I just skip the controller generating part or do I have to map the

Rails — create and create! methods, RoR 3 Tutorial

阅读更多关于 Rails — create and create! methods, RoR 3 Tutorial

问题 So I know the distinction between the bang (exclamation mark) and non-bang methods usually is whether the method will modify the object itself or return a separate modified object keeping the original unchanged. Then while building the User model in chapter 6 of the book, I came across the User.create method, which creates a new model and saves it to the database in a single step. In Michael Hartl's Ruby on Rails 3 Tutorial , he writes that the User.create! method "works just like the create

RSpec test destroy method (Rails Tutorial 3.2 Ch. 9, Ex. 10)

阅读更多关于 RSpec test destroy method (Rails Tutorial 3.2 Ch. 9, Ex. 10)

问题 Note: I've read this question and the answer, but for some reason the code isn't working for me. (see below for the error I'm getting) Exercise 10 from Chapter 9 of the Rails Tutorial asks you to: Modify the destroy action [for users] to prevent admin users from destroying themselves. (Write a test first.) The tricky part here is testing it, because the application already hides the "delete" link for the current user, so you have to do the http request directly. I got the code working, and

I'm attempting to follow the Hartl Rails Tutorial, and having trouble with the bundler gem. When using the commands 'bundle install' or 'bundle update' I get the following output: Fetching source index from https://rubygems.org/ Could not fetch specs from https://rubygems.org/ I've searched for this output, but did not find many related issues online. Maybe I have another gem that is interrupting bundler? I have little experience with rails at this point. source 'https://rubygems.org' gem 'rails', '3.2.12' group :development do gem 'sqlite3', '1.3.5' end # Gems used only for assets and not

Confused about 'respond_to' vs 'respond_to?'

阅读更多关于 Confused about 'respond_to' vs 'respond_to?'

问题 I am learning Rails with railstutorial.org, and I am confused about something: in this chapter the author tells us to do some testing in the console with the respond_to? method on a User object, and it works ok. But later, when we write the test for the :encrypted_password attribute, he uses respond_to . Out of curiosity, I tried respond_to in the console, for a User object, and I get an error saying the method doesnt exist. Alas, if I try to write the test using respond_to? instead of
