Building a Simple Ruby on Rails App (Rails 4 + Bootstrap 3)

I agree that Treehouse should probably push out an update for Rails 4 pretty soon, but their lesson is still very relevant; many apps out there are still on Rails 3 and utilize the Bootstrap 2 framework.

You can still use Bootstrap 2 from here: http://getbootstrap.com/2.3.2/

Or, for a more Railsy approach, you can use the awesome bootstrap-sass gem.

If you want to follow along with Treehouse's lesson exactly, you can set your Bootstrap gem to the specific version:

gem 'bootstrap-sass', '~> 2.3.2.1'

which is shorthand for

gem 'bootstrap-sass', '>= 2.3.2.1', '< 3.0'

which means use any gem version newer than 2.3.2.1 but don’t install 3.0 or anything newer.

Also, if you're just installing Rails, I'd recommend using RVM and specifying that you want to install Rails 3.2.14 rather than Rails 4.

Thank you! I will check out your github. I started this process a couple of days ago and it is much more painful than I had hoped.

This Railscast was pretty useful (http://railscasts.com/episodes/415-upgrading-to-rails-4). But I did run into a few problems there too. I installed 4.0.0 instead of rc1, I did not include 'gem paper_trail...' line, and I had to remove the 'patch :update_many' line. I am still getting ArgumentErrors - maybe you have all the answers. ;-)

True that

I faced the same problem about 6 weeks ago, but I got past it. The tutorial as a whole is very useful despite some inconsistencies. The only major differences I noticed are in the class names used for bootstrap (they changed) and strong params replacing attr accessible.

I actually took a few bootcamps that switched between rails 3 and 4, so I had that experience, but otherwise its mainly a strong_paramaters inconsistency, and some syntax errors.

I got stuck for a long while on the new condition syntax on models, I can't imagine how much work it must take to update all the videos to rails 4 for consistency. I agree it probably would be helpful, but I'd rather just one video update showing what to do for rails 4, or better yet, just new content that relates to rails and keeps me motivated!

I finished with the project. If you get stuck trying to use Rails 4 + Bootstrap 3, feel free to clone my repo: https://github.com/robthefrog/treebook

I tried to do a commit after each section.

Hey Rob, thank you for providing your repo. I've tested it and it works on my machine perfectly. I too am working through the Build a Simple Rails App tutorial using Rails 4 + Bootstrap 3. I went back through your project files and updated my own wherever I thought it looked appropriate, leaving out some of the later features (given that I'm at an earlier stage of the tutorial). However, I'm still stuck at the Creating Relationships section of the Customizing Forms badge and getting the error "NoMethodError in Statuses#index" and "undefined method `full_name' for nil:NilClass". Did you have to do any additional steps to get this working? Clear the database? Migrate it again? I'm able to signup a user and I can confirm that I'm signed in going to localhost:xxxx/users/edit. If you have the time ever and are willing to look at my repo, I would really appreciate it!!! In any case, I was about to totally give up on this project and my hope is now revitalized given that you've got it working. Thanks! https://github.com/jaredgalanis/treebook
