I'm new to ROR.
How can I use the same App name after I delete my rails App?
Following are the actions I performed. Step #6 is my problem.
1 - Environment
- OS : Ubuntu 12.04.4
- ruby : 2.1.1p76
- rails : 4.1.2
- DB : SQLite
2 - Create rails App :
rails new myApp
=> OK
3 - Create model :
rails generate model mytable name:string
=> OK.
4 - Delete rails App :
rm -rf myApp
=> OK
5 - Re-Create rails App :
rails new myApp
=> OK
6 - Re-Create model :
rails generate model mytable name:string
=> Not OK! waiting for infinite time

Make sure in it by looking at generated migration:
$ rails g model user email This command will generate user model with email field type of string, migration which creates users table, test for model and factory (if you have it). You are able to generate model with few fields like this: $ rails g model user first_name last_name email

Just a hunch, but by any chance, are you still running a server process somewhere on your machine? That could be holding a lock that is preventing the new table from getting built.

Don't kill spring, just use the built in spring stop
