You haven’t provided nearly enough detail for anyone to be able to help  
you. Post a step by step description of what you did, what happened, and  
what you expected to happen.

Oh, and posting your question a second time because you didn’t get an  
answer the first time is considered bad form.

Here is a step by step route i took:

1. rails materials
2. mysqladmin -u root create materials\_development
3. created model named Die
4. modified create\_dies migration and raked it
5. created controller Admin
6. added scaffold :die
