The code isn't working

I downloaded the code for RailsView. As I followed the readme, it gave full of craps when I type the command “rake setup”. I put the error below.

anyone gets these error messages?

Jooin -

nil method means that the parent class doesn’t have a relationship to client in this case. I’m taking a look at it with a fresh code download to see if I can replicate.

I can replicate in the Layout chapter. Working on a fix for you.

The issue is with the

ProjectSeeder.run(shirt, 'rubyconf2011-shirt', spade)

line, or the ProjectSeeder method entire perhaps.

Try changing this line in Gemfile:

gem "paperclip"

to

gem "paperclip", "~> 2.7"

and let me know if it works for you. Be sure to run rake db:drop first.

I was having the same problem. Changed the line in the Gemfile as above, then Paperclip complained about not having ImageMagick. I installed it on Ubuntu with:

Apparently the equivalent on MacOS is:

But that made everything work fine!
