added model specs

April, 

I read the resource you provided on creating model specs. It suggested testing the factories, so I wrote a test for the user factory. 5 hours later, I still cannot get the factory validated. The latest reason is that I have the wrong number of argument in my spec "   @user_attr = create(:user) " 

Could you take a look and see if anything stands out? The first problem was, since that blog post was written, statements like "Factory" have deprecated. I went to the latest FactoryGirl getting started guide and made some changes, then office hours, then stack overflow.......
