ruby on rails rake db：migrate error

Question

i'm starting to learn ruby on rails using this guide : getting_started , i created my project and database but when i run rake db:migrate i get this error:

@mona-Extensa-5230:~/rubyDev/Sites/blog# rake db:migrate
(in /home/mona/rubyDev/Sites/blog)
== CreatePosts: migrating ==================================================== -- create_table(:posts)
rake aborted!
An error has occurred, this and all later migrations canceled:
private method `String' called for#
ActiveRecord::ConnectionAdapters::TableDefinition:0xb7540f30>

thanks.

Answer 1

Looks like you have a line like this in one of your migrations:

t.String

Note that the s needs to be in lowercase ( t.string )
